+external libraries:
+-------------------
 
+Some external libraries, e.g. libx264, are under GPL and can be used in
+conjunction with FFmpeg. They require --enable-gpl to be passed to configure
+as well.
 
-external libraries
-==================
+The OpenCORE external libraries are under the Apache License 2.0. That license
+is incompatible with the LGPL v2.1 and the GPL v2, but not with version 3 of
+those licenses. So to combine the OpenCORE libraries with FFmpeg, the license
+version needs to be upgraded by passing --enable-version3 to configure.
 
-FFmpeg can be combined with a number of external libraries, which sometimes
-affect the licensing of binaries resulting from the combination.
-
-compatible libraries
---------------------
-
-The following libraries are under GPL:
-    - frei0r
-    - libcdio
-    - libutvideo
-    - libvidstab
-    - libx264
-    - libx265
-    - libxavs
-    - libxvid
-When combining them with FFmpeg, FFmpeg needs to be licensed as GPL as well by
-passing --enable-gpl to configure.
-
-The OpenCORE and VisualOn libraries are under the Apache License 2.0. That
-license is incompatible with the LGPL v2.1 and the GPL v2, but not with
-version 3 of those licenses. So to combine these libraries with FFmpeg, the
-license version needs to be upgraded by passing --enable-version3 to configure.
-
-incompatible libraries
-----------------------
-
-The Fraunhofer AAC library, FAAC and aacplus are under licenses which
-are incompatible with the GPLv2 and v3. We do not know for certain if their
-licenses are compatible with the LGPL.
-If you wish to enable these libraries, pass --enable-nonfree to configure.
-But note that if you enable any of these libraries the resulting binary will
-be under a complex license mix that is more restrictive than the LGPL and that
-may result in additional obligations. It is possible that these
-restrictions cause the resulting binary to be unredistributeable.
+The nonfree external libraries libamrnb, libamrwb and libfaac can be hooked up
+in FFmpeg. You need to pass --enable-nonfree to configure to enable them. Employ
+this option with care as FFmpeg then becomes nonfree and unredistributable.
+Note that libfaac claims to be LGPL, but is not.

-2.2.7
+Release Notes
+=============
+
+* 0.5 "Bike Shed World Domination" March 3, 2009
+
+General notes
+-------------
+
+It has been so long since the last release that this should be considered the
+first FFmpeg release of recent times. Because of the way things have unfolded to
+date, the notes for this version cannot be entirely conventional.
+
+See the Changelog file for a list of significant changes.
+
+Please note that our policy on bug reports has not changed. We still only accept
+bug reports against HEAD of the FFmpeg trunk repository. If you are experiencing
+any issues with any formally released version of FFmpeg, please try a current
+version of the development code to check if the issue still exists. If it does,
+make your report against the development code following the usual bug reporting
+guidelines.
+
+API notes
+---------
+
+In the next release, it is intended to remove a number of deprecated APIs. We
+decided to put out a release that includes said APIs for the benefit of third
+party software.
+
+As such, this release:
+- provides a sync point for said APIs
+- increases awareness of API changes
+- allows the next release to detail how to transition from the old to the new
+
+The deprecated APIs to be removed are:
+- imgconvert (to be replaced by libswscale)
+- vhook (to be replaced by libavfilter)
+
+If at all possible, do not use the deprecated APIs. All notes on API changes
+should appear in doc/APIchanges.
+
+
+
+* 0.5.1 March 2, 2010
+
+General notes
+-------------
+
+This point release includes some minor updates to make the 0.5 release series
+usable for users that need to retain the existing behavior as closely as
+possible. The changes follow below:
+
+Security fixes
+--------------
+
+Various programming errors in container and codec implementations
+may lead to denial of service or the execution of arbitrary code
+if the user is tricked into opening a malformed media file or stream.
+
+Affected and updated have been the implementations of the following
+codecs and container formats:
+
+ - the Vorbis audio codec
+ - the FF Video 1 codec
+ - the MPEG audio codec
+ - the H264 video codec
+ - the MLP codec
+ - the HuffYUV codec
+ - the ASF demuxer
+ - the Ogg container implementation
+ - the MOV container implementation
+
+Symbol Versioning enabled
+-------------------------
+
+The backported symbol versioning change is enabled on platforms that support
+it. This allows users to upgrade from 0.5.1 to the upcoming 0.6 release
+without having to recompile their applications. Please note that distributors
+have to recompile applications against 0.5.1 before upgrading to 0.6.
+
+libx264.c backport
+------------------
+
+This release includes a backport to the libx264 wrapper that allows FFmpeg to
+be compiled against newer versions of libx264 up to API version 85.
+
+licensing changes
+-----------------
+
+Previously both libswscale and our AC-3 decoder had GPLed parts. These have
+been replaced by fresh LGPL code. x86 optimizations for libswscale remain GPL,
+but the C code is fully functional. Optimizations for other architectures have
+been relicensed to LGPL.
+
+AMR-NB decoding/encoding and AMR-WB decoding is now possible through the free
+software OpenCORE libraries as an alternative to the non-free libamr libraries.
+
+We found out that libfaac contains non-free parts and is not LGPL as previously
+claimed. We have changed configure to reflect this. You now have to pass the
+--enable-nonfree option if you wish to compile with libfaac support enabled.
+
+Furthermore the non-free bits in libavcodec/fdctref.c have been rewritten. Note
+well that they were only used in a test program and never compiled into any
+FFmpeg library.
+
+
+
+* 0.5.2 May 25, 2010
+
+General notes
+-------------
+
+This is a maintenance-only release that addresses a small number of security
+and portability issues. Distributors and system integrators are encouraged
+to update and share their patches against this branch.

+This is (again) another maintenance-only release that addresses a fix
+for seekable HTTP and an exploitable bug in the FLIC decoder
+(cf. CVE-2010-3429 for details). Distributors and system integrators are
+encouraged to update and share their patches against this branch.
+
+
+
+* 0.5.4 Mar 17, 2011

+AVUtil
+======
+libavutil is a small lightweight library of generally useful functions.
+It is not a library for code needed by both libavcodec and libavformat.
+
+
+Overview:
+=========
+adler32.c               adler32 checksum
+aes.c                   AES encryption and decryption
+fifo.c                  resizeable first in first out buffer
+intfloat_readwrite.c    portable reading and writing of floating point values
+log.c                   "printf" with context and level
+md5.c                   MD5 Message-Digest Algorithm
+rational.c              code to perform exact calculations with rational numbers
+tree.c                  generic AVL tree
+crc.c                   generic CRC checksumming code
+integer.c               128bit integer math
+lls.c
+mathematics.c           greatest common divisor, integer sqrt, integer log2, ...
+mem.c                   memory allocation routines with guaranteed alignment
+softfloat.c
+
+Headers:
+bswap.h                 big/little/native-endian conversion code
+x86_cpu.h               a few useful macros for unifying x86-64 and x86-32 code
+avutil.h
+common.h
+intreadwrite.h          reading and writing of unaligned big/little/native-endian integers
+
+
+Goals:
+======
+* Modular (few interdependencies and the possibility of disabling individual parts during ./configure)
+* Small (source and object)
+* Efficient (low CPU and memory usage)
+* Useful (avoid useless features almost no one needs)

-@chapter Bitstream Filters
-@c man begin BITSTREAM FILTERS
-
-When you configure your FFmpeg build, all the supported bitstream
-filters are enabled by default. You can list all available ones using
-the configure option @code{--list-bsfs}.
-
-You can disable all the bitstream filters using the configure option
-@code{--disable-bsfs}, and selectively enable any bitstream filter using
-the option @code{--enable-bsf=BSF}, or you can disable a particular
-bitstream filter using the option @code{--disable-bsf=BSF}.
-
-The option @code{-bsfs} of the ff* tools will display the list of
-all the supported bitstream filters included in your build.
-
-Below is a description of the currently available bitstream filters.
-
-@section aac_adtstoasc
-
-Convert MPEG-2/4 AAC ADTS to MPEG-4 Audio Specific Configuration
-bitstream filter.
-
-This filter creates an MPEG-4 AudioSpecificConfig from an MPEG-2/4
-ADTS header and removes the ADTS header.
-
-This is required for example when copying an AAC stream from a raw
-ADTS AAC container to a FLV or a MOV/MP4 file.
-
-@section chomp
-
-Remove zero padding at the end of a packet.
-
-@section dump_extra
-
-Add extradata to the beginning of the filtered packets.
-
-The additional argument specifies which packets should be filtered.
-It accepts the values:
-@table @samp
-@item a
-add extradata to all key packets, but only if @var{local_header} is
-set in the @option{flags2} codec context field
-
-@item k
-add extradata to all key packets
-
-@item e
-add extradata to all packets
-@end table
-
-If not specified it is assumed @samp{k}.
-
-For example the following @command{ffmpeg} command forces a global
-header (thus disabling individual packet headers) in the H.264 packets
-generated by the @code{libx264} encoder, but corrects them by adding
-the header stored in extradata to the key packets:
-@example
-ffmpeg -i INPUT -map 0 -flags:v +global_header -c:v libx264 -bsf:v dump_extra out.ts
-@end example
-
-@section h264_mp4toannexb
-
-Convert an H.264 bitstream from length prefixed mode to start code
-prefixed mode (as defined in the Annex B of the ITU-T H.264
-specification).
-
-This is required by some streaming formats, typically the MPEG-2
-transport stream format ("mpegts").
-
-For example to remux an MP4 file containing an H.264 stream to mpegts
-format with @command{ffmpeg}, you can use the command:
-
-@example
-ffmpeg -i INPUT.mp4 -codec copy -bsf:v h264_mp4toannexb OUTPUT.ts
-@end example
-
-@section imx_dump_header
-
-@section mjpeg2jpeg
-
-Convert MJPEG/AVI1 packets to full JPEG/JFIF packets.
-
-MJPEG is a video codec wherein each video frame is essentially a
-JPEG image. The individual frames can be extracted without loss,
-e.g. by
-
-@example
-ffmpeg -i ../some_mjpeg.avi -c:v copy frames_%d.jpg
-@end example
-
-Unfortunately, these chunks are incomplete JPEG images, because
-they lack the DHT segment required for decoding. Quoting from
-@url{http://www.digitalpreservation.gov/formats/fdd/fdd000063.shtml}:
-
-Avery Lee, writing in the rec.video.desktop newsgroup in 2001,
-commented that "MJPEG, or at least the MJPEG in AVIs having the
-MJPG fourcc, is restricted JPEG with a fixed -- and *omitted* --
-Huffman table. The JPEG must be YCbCr colorspace, it must be 4:2:2,
-and it must use basic Huffman encoding, not arithmetic or
-progressive. . . . You can indeed extract the MJPEG frames and
-decode them with a regular JPEG decoder, but you have to prepend
-the DHT segment to them, or else the decoder won't have any idea
-how to decompress the data. The exact table necessary is given in
-the OpenDML spec."
-
-This bitstream filter patches the header of frames extracted from an MJPEG
-stream (carrying the AVI1 header ID and lacking a DHT segment) to
-produce fully qualified JPEG images.
-
-@example
-ffmpeg -i mjpeg-movie.avi -c:v copy -bsf:v mjpeg2jpeg frame_%d.jpg
-exiftran -i -9 frame*.jpg
-ffmpeg -i frame_%d.jpg -c:v copy rotated.avi
-@end example
-
-@section mjpega_dump_header
-
-@section movsub
-
-@section mp3_header_decompress

-@section noise

-@section remove_extra

-Useful standard make commands:
-make -t <target>
-    Touch all files that otherwise would be build, this is useful to reduce

-
-make -j<num>
-    rebuild with multiple jobs at the same time. Faster on multi processor systems
-
-make -k
-    continue build in case of errors, this is useful for the regression tests
-    sometimes but note it will still not run all reg tests.

-
-This codec decodes the bitmap subtitles used in DVDs; the same subtitles can
-also be found in VobSub file pairs and in some Matroska files.
-
-@subsection Options
-
-@table @option
-@item palette
-Specify the global palette used by the bitmaps. When stored in VobSub, the
-palette is normally specified in the index file; in Matroska, the palette is
-stored in the codec extra-data in the same format as in VobSub. In DVDs, the

-from dumped VOB files.
-
-The format for this option is a string containing 16 24-bits hexadecimal
-numbers (without 0x prefix) separated by comas, for example @code{0d00ee,
-ee450d, 101010, eaeaea, 0ce60b, ec14ed, ebff0b, 0d617a, 7b7b7b, d1d1d1,

-@section libzvbi-teletext
-
-Libzvbi allows libavcodec to decode DVB teletext pages and DVB teletext
-subtitles. Requires the presence of the libzvbi headers and library during
-configuration. You need to explicitly configure the build with
-@code{--enable-libzvbi}.
-
-@subsection Options
-
-@table @option
-@item txt_page
-List of teletext page numbers to decode. You may use the special * string to
-match all pages. Pages that do not match the specified list are dropped.
-Default value is *.
-@item txt_chop_top
-Discards the top teletext line. Default value is 1.
-@item txt_format
-Specifies the format of the decoded subtitles. The teletext decoder is capable
-of decoding the teletext pages to bitmaps or to simple text, you should use
-"bitmap" for teletext pages, because certain graphics and colors cannot be
-expressed in simple text. You might use "text" for teletext based subtitles if
-your application can handle simple text based subtitles. Default value is
-bitmap.
-@item txt_left
-X offset of generated bitmaps, default is 0.
-@item txt_top
-Y offset of generated bitmaps, default is 0.
-@item txt_chop_spaces
-Chops leading and trailing spaces and removes empty lines from the generated
-text. This option is useful for teletext based subtitles where empty spaces may
-be present at the start or at the end of the lines or empty lines may be
-present between the subtitle lines because of double-sized teletext charactes.
-Default value is 1.
-@item txt_duration
-Sets the display duration of the decoded teletext pages or subtitles in
-miliseconds. Default value is 30000 which is 30 seconds.
-@item txt_transparent
-Force transparent background of the generated teletext bitmaps. Default value
-is 0 which means an opaque (black) background.

-@chapter Demuxers
-@c man begin DEMUXERS
-
-Demuxers are configured elements in FFmpeg that can read the
-multimedia streams from a particular type of file.
-
-When you configure your FFmpeg build, all the supported demuxers
-are enabled by default. You can list all available ones using the
-configure option @code{--list-demuxers}.
-
-You can disable all the demuxers using the configure option
-@code{--disable-demuxers}, and selectively enable a single demuxer with
-the option @code{--enable-demuxer=@var{DEMUXER}}, or disable it
-with the option @code{--disable-demuxer=@var{DEMUXER}}.
-
-The option @code{-formats} of the ff* tools will display the list of
-enabled demuxers.
-
-The description of some of the currently available demuxers follows.
-
-@section applehttp
-
-Apple HTTP Live Streaming demuxer.
-
-This demuxer presents all AVStreams from all variant streams.
-The id field is set to the bitrate variant index number. By setting
-the discard flags on AVStreams (by pressing 'a' or 'v' in ffplay),
-the caller can decide which variant streams to actually receive.
-The total bitrate of the variant that the stream belongs to is
-available in a metadata key named "variant_bitrate".
-
-@section asf
-
-Advanced Systems Format demuxer.
-
-This demuxer is used to demux ASF files and MMS network streams.
-
-@table @option
-@item -no_resync_search @var{bool}
-Do not try to resynchronize by looking for a certain optional start code.
-@end table
-
-@anchor{concat}
-@section concat
-
-Virtual concatenation script demuxer.
-
-This demuxer reads a list of files and other directives from a text file and
-demuxes them one after the other, as if all their packet had been muxed
-together.
-
-The timestamps in the files are adjusted so that the first file starts at 0
-and each next file starts where the previous one finishes. Note that it is
-done globally and may cause gaps if all streams do not have exactly the same
-length.
-
-All files must have the same streams (same codecs, same time base, etc.).
-
-The duration of each file is used to adjust the timestamps of the next file:
-if the duration is incorrect (because it was computed using the bit-rate or
-because the file is truncated, for example), it can cause artifacts. The
-@code{duration} directive can be used to override the duration stored in
-each file.
-
-@subsection Syntax
-
-The script is a text file in extended-ASCII, with one directive per line.
-Empty lines, leading spaces and lines starting with '#' are ignored. The
-following directive is recognized:
-
-@table @option
-
-@item @code{file @var{path}}
-Path to a file to read; special characters and spaces must be escaped with
-backslash or single quotes.
-
-All subsequent directives apply to that file.
-
-@item @code{ffconcat version 1.0}
-Identify the script type and version. It also sets the @option{safe} option
-to 1 if it was to its default -1.
-
-To make FFmpeg recognize the format automatically, this directive must
-appears exactly as is (no extra space or byte-order-mark) on the very first
-line of the script.
-
-@item @code{duration @var{dur}}
-Duration of the file. This information can be specified from the file;
-specifying it here may be more efficient or help if the information from the
-file is not available or accurate.
-
-If the duration is set for all files, then it is possible to seek in the
-whole concatenated video.
-
-@end table
-
-@subsection Options
-
-This demuxer accepts the following option:
-
-@table @option
-
-@item safe
-If set to 1, reject unsafe file paths. A file path is considered safe if it
-does not contain a protocol specification and is relative and all components
-only contain characters from the portable character set (letters, digits,
-period, underscore and hyphen) and have no period at the beginning of a
-component.
-
-If set to 0, any file name is accepted.
-
-The default is -1, it is equivalent to 1 if the format was automatically
-probed and 0 otherwise.
-
-@end table
-
-@section flv
-
-Adobe Flash Video Format demuxer.
-
-This demuxer is used to demux FLV files and RTMP network streams.
-
-@table @option
-@item -flv_metadata @var{bool}
-Allocate the streams according to the onMetaData array content.
-@end table
-
-@section libgme
-
-The Game Music Emu library is a collection of video game music file emulators.
-
-See @url{http://code.google.com/p/game-music-emu/} for more information.
-
-Some files have multiple tracks. The demuxer will pick the first track by
-default. The @option{track_index} option can be used to select a different
-track. Track indexes start at 0. The demuxer exports the number of tracks as
-@var{tracks} meta data entry.
-
-For very large files, the @option{max_size} option may have to be adjusted.
-
-@section libquvi
-
-Play media from Internet services using the quvi project.
-
-The demuxer accepts a @option{format} option to request a specific quality. It
-is by default set to @var{best}.
-
-See @url{http://quvi.sourceforge.net/} for more information.
-
-FFmpeg needs to be built with @code{--enable-libquvi} for this demuxer to be
-enabled.
-
-@section image2
-
-Image file demuxer.
-
-This demuxer reads from a list of image files specified by a pattern.
-The syntax and meaning of the pattern is specified by the
-option @var{pattern_type}.
-
-The pattern may contain a suffix which is used to automatically
-determine the format of the images contained in the files.
-
-The size, the pixel format, and the format of each image must be the
-same for all the files in the sequence.
-
-This demuxer accepts the following options:
-@table @option
-@item framerate
-Set the frame rate for the video stream. It defaults to 25.
-@item loop
-If set to 1, loop over the input. Default value is 0.
-@item pattern_type
-Select the pattern type used to interpret the provided filename.
-
-@var{pattern_type} accepts one of the following values.
-@table @option
-@item sequence
-Select a sequence pattern type, used to specify a sequence of files
-indexed by sequential numbers.
-
-A sequence pattern may contain the string "%d" or "%0@var{N}d", which
-specifies the position of the characters representing a sequential
-number in each filename matched by the pattern. If the form
-"%d0@var{N}d" is used, the string representing the number in each
-filename is 0-padded and @var{N} is the total number of 0-padded
-digits representing the number. The literal character '%' can be
-specified in the pattern with the string "%%".
-
-If the sequence pattern contains "%d" or "%0@var{N}d", the first filename of
-the file list specified by the pattern must contain a number
-inclusively contained between @var{start_number} and
-@var{start_number}+@var{start_number_range}-1, and all the following
-numbers must be sequential.
-
-For example the pattern "img-%03d.bmp" will match a sequence of
-filenames of the form @file{img-001.bmp}, @file{img-002.bmp}, ...,
-@file{img-010.bmp}, etc.; the pattern "i%%m%%g-%d.jpg" will match a
-sequence of filenames of the form @file{i%m%g-1.jpg},
-@file{i%m%g-2.jpg}, ..., @file{i%m%g-10.jpg}, etc.
-
-Note that the pattern must not necessarily contain "%d" or
-"%0@var{N}d", for example to convert a single image file
-@file{img.jpeg} you can employ the command:
-@example
-ffmpeg -i img.jpeg img.png
-@end example
-
-@item glob
-Select a glob wildcard pattern type.
-
-The pattern is interpreted like a @code{glob()} pattern. This is only
-selectable if libavformat was compiled with globbing support.
-
-@item glob_sequence @emph{(deprecated, will be removed)}
-Select a mixed glob wildcard/sequence pattern.
-
-If your version of libavformat was compiled with globbing support, and
-the provided pattern contains at least one glob meta character among
-@code{%*?[]@{@}} that is preceded by an unescaped "%", the pattern is
-interpreted like a @code{glob()} pattern, otherwise it is interpreted
-like a sequence pattern.
-
-All glob special characters @code{%*?[]@{@}} must be prefixed
-with "%". To escape a literal "%" you shall use "%%".
-
-For example the pattern @code{foo-%*.jpeg} will match all the
-filenames prefixed by "foo-" and terminating with ".jpeg", and
-@code{foo-%?%?%?.jpeg} will match all the filenames prefixed with
-"foo-", followed by a sequence of three characters, and terminating
-with ".jpeg".
-
-This pattern type is deprecated in favor of @var{glob} and
-@var{sequence}.
-@end table
-
-Default value is @var{glob_sequence}.
-@item pixel_format
-Set the pixel format of the images to read. If not specified the pixel
-format is guessed from the first image file in the sequence.
-@item start_number
-Set the index of the file matched by the image file pattern to start
-to read from. Default value is 0.
-@item start_number_range
-Set the index interval range to check when looking for the first image
-file in the sequence, starting from @var{start_number}. Default value
-is 5.
-@item ts_from_file
-If set to 1, will set frame timestamp to modification time of image file. Note
-that monotonity of timestamps is not provided: images go in the same order as
-without this option. Default value is 0.
-@item video_size
-Set the video size of the images to read. If not specified the video
-size is guessed from the first image file in the sequence.
-@end table
-
-@subsection Examples
-
-@itemize
-@item
-Use @command{ffmpeg} for creating a video from the images in the file
-sequence @file{img-001.jpeg}, @file{img-002.jpeg}, ..., assuming an
-input frame rate of 10 frames per second:
-@example
-ffmpeg -framerate 10 -i 'img-%03d.jpeg' out.mkv
-@end example
-
-@item
-As above, but start by reading from a file with index 100 in the sequence:
-@example
-ffmpeg -framerate 10 -start_number 100 -i 'img-%03d.jpeg' out.mkv
-@end example
-
-@item
-Read images matching the "*.png" glob pattern , that is all the files
-terminating with the ".png" suffix:
-@example
-ffmpeg -framerate 10 -pattern_type glob -i "*.png" out.mkv
-@end example
-@end itemize
-
-@section mpegts
-
-MPEG-2 transport stream demuxer.
-
-@table @option
-
-@item fix_teletext_pts
-Overrides teletext packet PTS and DTS values with the timestamps calculated
-from the PCR of the first program which the teletext stream is part of and is
-not discarded. Default value is 1, set this option to 0 if you want your
-teletext packet PTS and DTS values untouched.
-@end table
-
-@section rawvideo
-
-Raw video demuxer.
-
-This demuxer allows one to read raw video data. Since there is no header
-specifying the assumed video parameters, the user must specify them
-in order to be able to decode the data correctly.
-
-This demuxer accepts the following options:
-@table @option
-
-@item framerate
-Set input video frame rate. Default value is 25.
-
-@item pixel_format
-Set the input video pixel format. Default value is @code{yuv420p}.
-
-@item video_size
-Set the input video size. This value must be specified explicitly.
-@end table
-
-For example to read a rawvideo file @file{input.raw} with
-@command{ffplay}, assuming a pixel format of @code{rgb24}, a video
-size of @code{320x240}, and a frame rate of 10 images per second, use
-the command:
-@example
-ffplay -f rawvideo -pixel_format rgb24 -video_size 320x240 -framerate 10 input.raw
-@end example
-
-@section sbg
-
-SBaGen script demuxer.
-
-This demuxer reads the script language used by SBaGen
-@url{http://uazu.net/sbagen/} to generate binaural beats sessions. A SBG
-script looks like that:
-@example
--SE
-a: 300-2.5/3 440+4.5/0
-b: 300-2.5/0 440+4.5/3
-off: -
-NOW      == a
-+0:07:00 == b
-+0:14:00 == a
-+0:21:00 == b
-+0:30:00    off
-@end example
-
-A SBG script can mix absolute and relative timestamps. If the script uses
-either only absolute timestamps (including the script start time) or only
-relative ones, then its layout is fixed, and the conversion is
-straightforward. On the other hand, if the script mixes both kind of
-timestamps, then the @var{NOW} reference for relative timestamps will be
-taken from the current time of day at the time the script is read, and the
-script layout will be frozen according to that reference. That means that if
-the script is directly played, the actual times will match the absolute
-timestamps up to the sound controller's clock accuracy, but if the user
-somehow pauses the playback or seeks, all times will be shifted accordingly.
-
-@section tedcaptions
-
-JSON captions used for @url{http://www.ted.com/, TED Talks}.
-
-TED does not provide links to the captions, but they can be guessed from the
-page. The file @file{tools/bookmarklets.html} from the FFmpeg source tree
-contains a bookmarklet to expose them.
-
-This demuxer accepts the following option:
-@table @option
-@item start_time
-Set the start time of the TED talk, in milliseconds. The default is 15000
-(15s). It is used to sync the captions with the downloadable videos, because
-they include a 15s intro.
-@end table
-
-Example: convert the captions to a format most players understand:
-@example
-ffmpeg -i http://www.ted.com/talks/subtitles/id/1/lang/en talk1-en.srt

-      see @ref{Submitting patches} for details.

-
-Whichever way, changes should be reviewed by the maintainer of the code
-before they are committed. And they should follow the @ref{Coding Rules}.
-The developer making the commit and the author are responsible for their changes
-and should try to fix issues their commit causes.

-@section Coding Rules
-
-@subsection Code formatting conventions
-
-There are the following guidelines regarding the indentation in files:
-
-@itemize @bullet
-@item
-Indent size is 4.
-
-@item
-The TAB character is forbidden outside of Makefiles as is any
-form of trailing whitespace. Commits containing either will be
-rejected by the git repository.
-
-@item
-You should try to limit your code lines to 80 characters; however, do so if
-and only if this improves readability.
-@end itemize
-The presentation is one inspired by 'indent -i4 -kr -nut'.
-
-The main priority in FFmpeg is simplicity and small code size in order to
-minimize the bug count.
-
-@subsection Comments
-Use the JavaDoc/Doxygen  format (see examples below) so that code documentation
-can be generated automatically. All nontrivial functions should have a comment
-above them explaining what the function does, even if it is just one sentence.
-All structures and their member variables should be documented, too.
-
-Avoid Qt-style and similar Doxygen syntax with @code{!} in it, i.e. replace
-@code{//!} with @code{///} and similar.  Also @@ syntax should be employed
-for markup commands, i.e. use @code{@@param} and not @code{\param}.
-
-@example
-/**
- * @@file
- * MPEG codec.
- * @@author ...
- */
-
-/**
- * Summary sentence.
- * more text ...
- * ...
- */
-typedef struct Foobar @{
-    int var1; /**< var1 description */
-    int var2; ///< var2 description
-    /** var3 description */
-    int var3;
-@} Foobar;
-
-/**
- * Summary sentence.
- * more text ...
- * ...
- * @@param my_parameter description of my_parameter
- * @@return return value description
- */
-int myfunc(int my_parameter)
-...
-@end example
-
-@subsection C language features
-
-FFmpeg is programmed in the ISO C90 language with a few additional
-features from ISO C99, namely:
-
-@itemize @bullet
-@item
-the @samp{inline} keyword;
-
-@item
-@samp{//} comments;
-
-@item
-designated struct initializers (@samp{struct s x = @{ .i = 17 @};})
-
-@item
-compound literals (@samp{x = (struct s) @{ 17, 23 @};})
-@end itemize
-
-These features are supported by all compilers we care about, so we will not
-accept patches to remove their use unless they absolutely do not impair
-clarity and performance.
-
-All code must compile with recent versions of GCC and a number of other
-currently supported compilers. To ensure compatibility, please do not use
-additional C99 features or GCC extensions. Especially watch out for:
-
-@itemize @bullet
-@item
-mixing statements and declarations;
-
-@item
-@samp{long long} (use @samp{int64_t} instead);
-
-@item
-@samp{__attribute__} not protected by @samp{#ifdef __GNUC__} or similar;
-
-@item
-GCC statement expressions (@samp{(x = (@{ int y = 4; y; @})}).
-@end itemize
-
-@subsection Naming conventions
-All names should be composed with underscores (_), not CamelCase. For example,
-@samp{avfilter_get_video_buffer} is an acceptable function name and
-@samp{AVFilterGetVideo} is not. The exception from this are type names, like
-for example structs and enums; they should always be in the CamelCase
-
-There are the following conventions for naming variables and functions:
-
-@itemize @bullet
-@item
-For local variables no prefix is required.
-
-@item
-For file-scope variables and functions declared as @code{static}, no prefix
-is required.
-
-@item
-For variables and functions visible outside of file scope, but only used
-internally by a library, an @code{ff_} prefix should be used,
-e.g. @samp{ff_w64_demuxer}.
-
-@item
-For variables and functions visible outside of file scope, used internally
-across multiple libraries, use @code{avpriv_} as prefix, for example,
-@samp{avpriv_aac_parse_header}.
-
-@item
-Each library has its own prefix for public symbols, in addition to the
-commonly used @code{av_} (@code{avformat_} for libavformat,
-@code{avcodec_} for libavcodec, @code{swr_} for libswresample, etc).
-Check the existing code and choose names accordingly.
-Note that some symbols without these prefixes are also exported for
-retro-compatibility reasons. These exceptions are declared in the
-@code{lib<name>/lib<name>.v} files.
-@end itemize
-
-Furthermore, name space reserved for the system should not be invaded.
-Identifiers ending in @code{_t} are reserved by
-@url{http://pubs.opengroup.org/onlinepubs/007904975/functions/xsh_chap02_02.html#tag_02_02_02, POSIX}.
-Also avoid names starting with @code{__} or @code{_} followed by an uppercase
-letter as they are reserved by the C standard. Names starting with @code{_}
-are reserved at the file level and may not be used for externally visible
-symbols. If in doubt, just avoid names starting with @code{_} altogether.
-
-@subsection Miscellaneous conventions
-
-@itemize @bullet
-@item
-fprintf and printf are forbidden in libavformat and libavcodec,
-please use av_log() instead.
-
-@item
-Casts should be used only when necessary. Unneeded parentheses
-should also be avoided if they don't make the code easier to understand.
-@end itemize
-
-@subsection Editor configuration
-In order to configure Vim to follow FFmpeg formatting conventions, paste
-the following snippet into your @file{.vimrc}:
-@example
-" indentation rules for FFmpeg: 4 spaces, no tabs
-set expandtab
-set shiftwidth=4
-set softtabstop=4
-set cindent
-set cinoptions=(0
-" Allow tabs in Makefiles.
-autocmd FileType make,automake set noexpandtab shiftwidth=8 softtabstop=8
-" Trailing whitespace and tabs are forbidden, so highlight them.
-highlight ForbiddenWhitespace ctermbg=red guibg=red
-match ForbiddenWhitespace /\s\+$\|\t/
-" Do not highlight spaces at the end of line while typing on that line.
-autocmd InsertEnter * match ForbiddenWhitespace /\t\|\s\+\%#\@@<!$/
-@end example
-
-For Emacs, add these roughly equivalent lines to your @file{.emacs.d/init.el}:
-@example
-(c-add-style "ffmpeg"
-             '("k&r"
-               (c-basic-offset . 4)
-               (indent-tabs-mode . nil)
-               (show-trailing-whitespace . t)
-               (c-offsets-alist
-                (statement-cont . (c-lineup-assignments +)))
-               )
-             )
-(setq c-default-style "ffmpeg")
-@end example

-@section Development Policy
-
-@enumerate
-@item
-Contributions should be licensed under the
-@uref{http://www.gnu.org/licenses/lgpl-2.1.html, LGPL 2.1},
-including an "or any later version" clause, or, if you prefer
-a gift-style license, the
-@uref{http://opensource.org/licenses/isc-license.txt, ISC} or
-@uref{http://mit-license.org/, MIT} license.
-@uref{http://www.gnu.org/licenses/gpl-2.0.html, GPL 2} including
-an "or any later version" clause is also acceptable, but LGPL is
-preferred.
-If you add a new file, give it a proper license header. Do not copy and
-paste it from a random place, use an existing file as template.
-
-@item
-You must not commit code which breaks FFmpeg! (Meaning unfinished but
-enabled code which breaks compilation or compiles but does not work or
-breaks the regression tests)
-You can commit unfinished stuff (for testing etc), but it must be disabled
-(#ifdef etc) by default so it does not interfere with other developers'
-work.
-
-@item
-The commit message should have a short first line in the form of
-a @samp{topic: short description} as a header, separated by a newline
-from the body consisting of an explanation of why the change is necessary.
-If the commit fixes a known bug on the bug tracker, the commit message
-should include its bug ID. Referring to the issue on the bug tracker does
-not exempt you from writing an excerpt of the bug in the commit message.
-
-@item
-You do not have to over-test things. If it works for you, and you think it
-should work for others, then commit. If your code has problems
-(portability, triggers compiler bugs, unusual environment etc) they will be
-reported and eventually fixed.
-
-@item
-Do not commit unrelated changes together, split them into self-contained
-pieces. Also do not forget that if part B depends on part A, but A does not
-depend on B, then A can and should be committed first and separate from B.
-Keeping changes well split into self-contained parts makes reviewing and
-understanding them on the commit log mailing list easier. This also helps
-in case of debugging later on.
-Also if you have doubts about splitting or not splitting, do not hesitate to
-ask/discuss it on the developer mailing list.
-
-@item
-Do not change behavior of the programs (renaming options etc) or public
-API or ABI without first discussing it on the ffmpeg-devel mailing list.
-Do not remove functionality from the code. Just improve!
-
-Note: Redundant code can be removed.
-
-@item
-Do not commit changes to the build system (Makefiles, configure script)
-which change behavior, defaults etc, without asking first. The same
-applies to compiler warning fixes, trivial looking fixes and to code
-maintained by other developers. We usually have a reason for doing things
-the way we do. Send your changes as patches to the ffmpeg-devel mailing
-list, and if the code maintainers say OK, you may commit. This does not
-apply to files you wrote and/or maintain.
-
-@item
-We refuse source indentation and other cosmetic changes if they are mixed
-with functional changes, such commits will be rejected and removed. Every
-developer has his own indentation style, you should not change it. Of course
-if you (re)write something, you can use your own style, even though we would
-prefer if the indentation throughout FFmpeg was consistent (Many projects
-force a given indentation style - we do not.). If you really need to make
-indentation changes (try to avoid this), separate them strictly from real
-changes.
-
-NOTE: If you had to put if()@{ .. @} over a large (> 5 lines) chunk of code,
-then either do NOT change the indentation of the inner part within (do not
-move it to the right)! or do so in a separate commit
-
-@item
-Always fill out the commit log message. Describe in a few lines what you
-changed and why. You can refer to mailing list postings if you fix a
-particular bug. Comments such as "fixed!" or "Changed it." are unacceptable.
-Recommended format:
-area changed: Short 1 line description
-
-details describing what and why and giving references.
-
-@item
-Make sure the author of the commit is set correctly. (see git commit --author)
-If you apply a patch, send an
-answer to ffmpeg-devel (or wherever you got the patch from) saying that
-you applied the patch.
-
-@item
-When applying patches that have been discussed (at length) on the mailing
-list, reference the thread in the log message.
-
-@item
-Do NOT commit to code actively maintained by others without permission.
-Send a patch to ffmpeg-devel instead. If no one answers within a reasonable
-timeframe (12h for build failures and security fixes, 3 days small changes,
-1 week for big patches) then commit your patch if you think it is OK.
-Also note, the maintainer can simply ask for more time to review!
-
-@item
-Subscribe to the ffmpeg-cvslog mailing list. The diffs of all commits
-are sent there and reviewed by all the other developers. Bugs and possible
-improvements or general questions regarding commits are discussed there. We
-expect you to react if problems with your code are uncovered.
-
-@item
-Update the documentation if you change behavior or add features. If you are
-unsure how best to do this, send a patch to ffmpeg-devel, the documentation
-maintainer(s) will review and commit your stuff.
-
-@item
-Try to keep important discussions and requests (also) on the public
-developer mailing list, so that all developers can benefit from them.
-
-@item
-Never write to unallocated memory, never write over the end of arrays,
-always check values read from some untrusted source before using them
-as array index or other risky things.
-
-@item
-Remember to check if you need to bump versions for the specific libav*
-parts (libavutil, libavcodec, libavformat) you are changing. You need
-to change the version integer.
-Incrementing the first component means no backward compatibility to
-previous versions (e.g. removal of a function from the public API).
-Incrementing the second component means backward compatible change
-(e.g. addition of a function to the public API or extension of an
-existing data structure).
-Incrementing the third component means a noteworthy binary compatible
-change (e.g. encoder bug fix that matters for the decoder). The third
-component always starts at 100 to distinguish FFmpeg from Libav.
-
-@item
-Compiler warnings indicate potential bugs or code with bad style. If a type of
-warning always points to correct and clean code, that warning should
-be disabled, not the code changed.
-Thus the remaining warnings can either be bugs or correct code.
-If it is a bug, the bug has to be fixed. If it is not, the code should
-be changed to not generate a warning unless that causes a slowdown
-or obfuscates the code.
-
-@item
-Make sure that no parts of the codebase that you maintain are missing from the
-@file{MAINTAINERS} file. If something that you want to maintain is missing add it with
-your name after it.
-If at some point you no longer want to maintain some code, then please help
-finding a new maintainer and also don't forget updating the @file{MAINTAINERS} file.
-@end enumerate
-
-We think our rules are not too hard. If you have comments, contact us.
-
-@anchor{Submitting patches}
-@section Submitting patches
-
-First, read the @ref{Coding Rules} above if you did not yet, in particular
-the rules regarding patch submission.
-
-When you submit your patch, please use @code{git format-patch} or
-@code{git send-email}. We cannot read other diffs :-)
-
-Also please do not submit a patch which contains several unrelated changes.
-Split it into separate, self-contained pieces. This does not mean splitting
-file by file. Instead, make the patch as small as possible while still
-keeping it as a logical unit that contains an individual change, even
-if it spans multiple files. This makes reviewing your patches much easier
-for us and greatly increases your chances of getting your patch applied.
-
-Use the patcheck tool of FFmpeg to check your patch.
-The tool is located in the tools directory.
-
-Run the @ref{Regression tests} before submitting a patch in order to verify
-it does not cause unexpected problems.
-
-It also helps quite a bit if you tell us what the patch does (for example
-'replaces lrint by lrintf'), and why (for example '*BSD isn't C99 compliant
-and has no lrint()')
-
-Also please if you send several patches, send each patch as a separate mail,
-do not attach several unrelated patches to the same mail.
-
-Patches should be posted to the
-@uref{http://lists.ffmpeg.org/mailman/listinfo/ffmpeg-devel, ffmpeg-devel}
-mailing list. Use @code{git send-email} when possible since it will properly
-send patches without requiring extra care. If you cannot, then send patches
-as base64-encoded attachments, so your patch is not trashed during
-transmission.
-
-Your patch will be reviewed on the mailing list. You will likely be asked
-to make some changes and are expected to send in an improved version that
-incorporates the requests from the review. This process may go through
-several iterations. Once your patch is deemed good enough, some developer
-will pick it up and commit it to the official FFmpeg tree.
-
-Give us a few days to react. But if some time passes without reaction,
-send a reminder by email. Your patch should eventually be dealt with.

-
-@section New codecs or formats checklist
-
-@enumerate
-@item
-Did you use av_cold for codec initialization and close functions?
-
-@item
-Did you add a long_name under NULL_IF_CONFIG_SMALL to the AVCodec or
-AVInputFormat/AVOutputFormat struct?
-
-@item
-Did you bump the minor version number (and reset the micro version
-number) in @file{libavcodec/version.h} or @file{libavformat/version.h}?
-
-@item
-Did you register it in @file{allcodecs.c} or @file{allformats.c}?
-
-@item
-Did you add the AVCodecID to @file{avcodec.h}?
-When adding new codec IDs, also add an entry to the codec descriptor
-list in @file{libavcodec/codec_desc.c}.
-
-@item
-If it has a FourCC, did you add it to @file{libavformat/riff.c},
-even if it is only a decoder?
-
-@item
-Did you add a rule to compile the appropriate files in the Makefile?
-Remember to do this even if you're just adding a format to a file that is
-already being compiled by some other rule, like a raw demuxer.
-
-@item
-Did you add an entry to the table of supported formats or codecs in
-@file{doc/general.texi}?
-
-@item
-Did you add an entry in the Changelog?
-
-@item
-If it depends on a parser or a library, did you add that dependency in
-configure?
-
-@item
-Did you @code{git add} the appropriate files before committing?
-
-@item
-Did you make sure it compiles standalone, i.e. with
-@code{configure --disable-everything --enable-decoder=foo}
-(or @code{--enable-demuxer} or whatever your component is)?

-
-@item
-Did you provide a clear git commit log message?
-
-@item
-Is the patch against latest FFmpeg git master branch?
-
-@item
-Are you subscribed to ffmpeg-devel?
-(the list is subscribers only due to spam)
-
-@item
-Have you checked that the changes are minimal, so that the same cannot be
-achieved with a smaller patch and/or simpler final code?
-
-@item
-If the change is to speed critical code, did you benchmark it?
-
-@item
-If you did any benchmarks, did you provide them in the mail?
-
-@item
-Have you checked that the patch does not introduce buffer overflows or

-
-@item
-Did you test your decoder or demuxer against damaged data? If no, see
-tools/trasher, the noise bitstream filter, and
-@uref{http://caca.zoy.org/wiki/zzuf, zzuf}. Your decoder or demuxer
-should not crash, end in a (near) infinite loop, or allocate ridiculous
-amounts of memory when fed damaged data.
-
-@item
-Does the patch not mix functional and cosmetic changes?
-
-@item
-Did you add tabs or trailing whitespace to the code? Both are forbidden.
-
-@item
-Is the patch attached to the email you send?
-
-@item
-Is the mime type of the patch correct? It should be text/x-diff or
-text/x-patch or at least text/plain and not application/octet-stream.
-
-@item
-If the patch fixes a bug, did you provide a verbose analysis of the bug?
-
-@item
-If the patch fixes a bug, did you provide enough information, including

-Note please do not attach samples >100k to mails but rather provide a
-URL, you can upload to ftp://upload.ffmpeg.org
-
-@item
-Did you provide a verbose summary about what the patch does change?
-
-@item
-Did you provide a verbose explanation why it changes things like it does?
-

-
-@item
-Did you provide an example so we can verify the new feature added by the
-patch easily?
-
-@item
-If you added a new file, did you insert a license header? It should be
-taken from FFmpeg, not randomly copied and pasted from somewhere else.
-
-@item
-You should maintain alphabetical order in alphabetically ordered lists as
-long as doing so does not break API/ABI compatibility.
-
-@item
-Lines with similar content should be aligned vertically when doing so
-improves readability.
-
-@item
-Consider to add a regression test for your code.
-
-@item
-If you added YASM code please check that things still work with --disable-yasm
-
-@item
-Make sure you check the return values of function and return appropriate
-error codes. Especially memory allocation functions like @code{av_malloc()}
-are notoriously left unchecked, which is a serious problem.
-
-@item
-Test your code with valgrind and or Address Sanitizer to ensure it's free
-of leaks, out of array accesses, etc.
-@end enumerate
-
-@section Patch review process
-
-All patches posted to ffmpeg-devel will be reviewed, unless they contain a
-clear note that the patch is not for the git master branch.
-Reviews and comments will be posted as replies to the patch on the
-mailing list. The patch submitter then has to take care of every comment,
-that can be by resubmitting a changed patch or by discussion. Resubmitted
-patches will themselves be reviewed like any other patch. If at some point
-a patch passes review with no comments then it is approved, that can for
-simple and small patches happen immediately while large patches will generally
-have to be changed and reviewed many times before they are approved.
-After a patch is approved it will be committed to the repository.
-
-We will review all submitted patches, but sometimes we are quite busy so
-especially for large patches this can take several weeks.
-
-If you feel that the review process is too slow and you are willing to try to
-take over maintainership of the area of code you change then just clone
-git master and maintain the area of code there. We will merge each area from
-where its best maintained.
-
-When resubmitting patches, please do not make any significant changes
-not related to the comments received during review. Such patches will
-be rejected. Instead, submit significant changes or new features as
-separate patches.
-
-@anchor{Regression tests}
-@section Regression tests
-
-Before submitting a patch (or committing to the repository), you should at least
-test that you did not break anything.
-
-Running 'make fate' accomplishes this, please see @url{fate.html} for details.
-
-[Of course, some patches may change the results of the regression tests. In
-this case, the reference results of the regression tests shall be modified
-accordingly].
-
-@subsection Adding files to the fate-suite dataset
-
-When there is no muxer or encoder available to generate test media for a
-specific test then the media has to be inlcuded in the fate-suite.
-First please make sure that the sample file is as small as possible to test the
-respective decoder or demuxer sufficiently. Large files increase network
-bandwidth and disk space requirements.
-Once you have a working fate test and fate sample, provide in the commit
-message or introductionary message for the patch series that you post to
-the ffmpeg-devel mailing list, a direct link to download the sample media.
-
-
-@subsection Visualizing Test Coverage
-
-The FFmpeg build system allows visualizing the test coverage in an easy
-manner with the coverage tools @code{gcov}/@code{lcov}.  This involves
-the following steps:
-
-@enumerate
-@item
-    Configure to compile with instrumentation enabled:
-    @code{configure --toolchain=gcov}.
-
-@item
-    Run your test case, either manually or via FATE. This can be either
-    the full FATE regression suite, or any arbitrary invocation of any
-    front-end tool provided by FFmpeg, in any combination.
-
-@item
-    Run @code{make lcov} to generate coverage data in HTML format.
-
-@item
-    View @code{lcov/index.html} in your preferred HTML viewer.
-@end enumerate
-
-You can use the command @code{make lcov-reset} to reset the coverage
-measurements. You will need to rerun @code{make lcov} after running a
-new test.
-
-@subsection Using Valgrind
-
-The configure script provides a shortcut for using valgrind to spot bugs
-related to memory handling. Just add the option
-@code{--toolchain=valgrind-memcheck} or @code{--toolchain=valgrind-massif}
-to your configure line, and reasonable defaults will be set for running
-FATE under the supervision of either the @strong{memcheck} or the
-@strong{massif} tool of the valgrind suite.
-
-In case you need finer control over how valgrind is invoked, use the
-@code{--target-exec='valgrind <your_custom_valgrind_options>} option in
-your configure line instead.
-
-@anchor{Release process}
-@section Release process
-
-FFmpeg maintains a set of @strong{release branches}, which are the
-recommended deliverable for system integrators and distributors (such as
-Linux distributions, etc.). At regular times, a @strong{release
-manager} prepares, tests and publishes tarballs on the
-@url{http://ffmpeg.org} website.
-
-There are two kinds of releases:
-
-@enumerate
-@item
-@strong{Major releases} always include the latest and greatest
-features and functionality.
-
-@item
-@strong{Point releases} are cut from @strong{release} branches,
-which are named @code{release/X}, with @code{X} being the release
-version number.
-@end enumerate
-
-Note that we promise to our users that shared libraries from any FFmpeg
-release never break programs that have been @strong{compiled} against
-previous versions of @strong{the same release series} in any case!
-
-However, from time to time, we do make API changes that require adaptations
-in applications. Such changes are only allowed in (new) major releases and
-require further steps such as bumping library version numbers and/or
-adjustments to the symbol versioning file. Please discuss such changes
-on the @strong{ffmpeg-devel} mailing list in time to allow forward planning.
-
-@anchor{Criteria for Point Releases}
-@subsection Criteria for Point Releases
-
-Changes that match the following criteria are valid candidates for
-inclusion into a point release:
-
-@enumerate
-@item
-Fixes a security issue, preferably identified by a @strong{CVE
-number} issued by @url{http://cve.mitre.org/}.
-
-@item
-Fixes a documented bug in @url{https://trac.ffmpeg.org}.
-
-@item
-Improves the included documentation.
-
-@item
-Retains both source code and binary compatibility with previous
-point releases of the same release branch.
-@end enumerate
-
-The order for checking the rules is (1 OR 2 OR 3) AND 4.
-
-
-@subsection Release Checklist
-
-The release process involves the following steps:
-
-@enumerate
-@item
-Ensure that the @file{RELEASE} file contains the version number for
-the upcoming release.

-@chapter Device Options
-@c man begin DEVICE OPTIONS
-
-The libavdevice library provides the same interface as
-libavformat. Namely, an input device is considered like a demuxer, and
-an output device like a muxer, and the interface and generic device
-options are the same provided by libavformat (see the ffmpeg-formats
-manual).
-
-In addition each input or output device may support so-called private
-options, which are specific for that component.
-
-Options may be set by specifying -@var{option} @var{value} in the
-FFmpeg tools, or by setting the value explicitly in the device
-@code{AVFormatContext} options or using the @file{libavutil/opt.h} API
-for programmatic use.

-FFmpeg examples README
-----------------------
-
-Both following use cases rely on pkg-config and make, thus make sure
-that you have them installed and working on your system.
-
-
-Method 1: build the installed examples in a generic read/write user directory
-
-Copy to a read/write user directory and just use "make", it will link
-to the libraries on your system, assuming the PKG_CONFIG_PATH is
-correctly configured.
-
-Method 2: build the examples in-tree
-
-Assuming you are in the source FFmpeg checkout directory, you need to build
-FFmpeg (no need to make install in any prefix). Then just run "make examples".
-This will build the examples using the FFmpeg build system. You can clean those
-examples using "make examplesclean"
-
-If you want to try the dedicated Makefile examples (to emulate the first
-method), go into doc/examples and run a command such as
-PKG_CONFIG_PATH=pc-uninstalled make.

-/**
- * @file
- * libavfilter API usage example.
- *
- * @example filter_audio.c
- * This example will generate a sine wave audio,
- * pass it through a simple filter chain, and then compute the MD5 checksum of
- * the output data.
- *
- * The filter chain it uses is:
- * (input) -> abuffer -> volume -> aformat -> abuffersink -> (output)
- *
- * abuffer: This provides the endpoint where you can feed the decoded samples.
- * volume: In this example we hardcode it to 0.90.
- * aformat: This converts the samples to the samplefreq, channel layout,
- *          and sample format required by the audio device.
- * abuffersink: This provides the endpoint where you can read the samples after
- *              they have passed through the filter chain.

 @chapter General Questions
 
+@section When will the next FFmpeg version be released? / Why are FFmpeg releases so few and far between?
+
+Like most open source projects FFmpeg suffers from a certain lack of
+manpower. For this reason the developers have to prioritize the work
+they do and putting out releases is not at the top of the list, fixing
+bugs and reviewing patches takes precedence. Please don't complain or
+request more timely and/or frequent releases unless you are willing to
+help out creating them.
+
+@section I have a problem with an old version of FFmpeg; where should I report it?
+Nowhere. Upgrade to the latest release or if there is no recent release upgrade
+to Subversion HEAD. You could also try to report it. Maybe you will get lucky and
+become the first person in history to get an answer different from "upgrade
+to Subversion HEAD".

-
-FFmpeg has a @url{http://ffmpeg.org/ffmpeg-filters.html#concat,
-@code{concat}} filter designed specifically for that, with examples in the
-documentation. This operation is recommended if you need to re-encode.
-
-@subsection Concatenating using the concat @emph{demuxer}
-
-FFmpeg has a @url{http://www.ffmpeg.org/ffmpeg-formats.html#concat,
-@code{concat}} demuxer which you can use when you want to avoid a re-encode and
-your format doesn't support file level concatenation.

-@subsection Concatenating using the concat @emph{protocol} (file level)

+A few multimedia containers (MPEG-1, MPEG-2 PS, DV) allow to join video files by

 format of choice.

+ffmpeg -i intermediate_all.mpg -sameq output.avi
 @end example
 
-Additionally, you can use the @code{concat} protocol instead of @code{cat} or
-@code{copy} which will avoid creation of a potentially huge intermediate file.
+Notice that you should either use @code{-sameq} or set a reasonably high
+bitrate for your intermediate and output files, if you want to preserve

-@subsection Concatenating using raw audio and video

 Similarly, the yuv4mpegpipe format, and the raw video, raw audio codecs also
 allow concatenation, and the transcoding step is almost lossless.

-@section Why does FFmpeg not see the subtitles in my VOB file?
-
-VOB and a few other formats do not have a global header that describes
-everything present in the file. Instead, applications are supposed to scan
-the file to see what it contains. Since VOB files are frequently large, only
-the beginning is scanned. If the subtitles happen only later in the file,
-they will not be initally detected.
-
-Some applications, including the @code{ffmpeg} command-line tool, can only
-work with streams that were detected during the initial scan; streams that
-are detected later are ignored.
-
-The size of the initial scan is controlled by two options: @code{probesize}
-(default ~5 Mo) and @code{analyzeduration} (default 5,000,000 µs = 5 s). For
-the subtitle stream to be detected, both values must be large enough.
-
-@section Why was the @command{ffmpeg} @option{-sameq} option removed? What to use instead?
-
-The @option{-sameq} option meant "same quantizer", and made sense only in a
-very limited set of cases. Unfortunately, a lot of people mistook it for
-"same quality" and used it in places where it did not make sense: it had
-roughly the expected visible effect, but achieved it in a very inefficient
-way.
-
-Each encoder has its own set of options to set the quality-vs-size balance,
-use the options for the encoder you are using to set the quality level to a
-point acceptable for your tastes. The most common options to do that are
-@option{-qscale} and @option{-qmax}, but you should peruse the documentation
-of the encoder you chose.

-@chapter Introduction
-
-  FATE is an extended regression suite on the client-side and a means
-for results aggregation and presentation on the server-side.
-
-  The first part of this document explains how you can use FATE from
-your FFmpeg source directory to test your ffmpeg binary. The second
-part describes how you can run FATE to submit the results to FFmpeg's
-FATE server.
-
-  In any way you can have a look at the publicly viewable FATE results
-by visiting this website:
-
-  @url{http://fate.ffmpeg.org/}
-
-  This is especially recommended for all people contributing source
-code to FFmpeg, as it can be seen if some test on some platform broke
-with their recent contribution. This usually happens on the platforms
-the developers could not test on.
-
-  The second part of this document describes how you can run FATE to
-submit your results to FFmpeg's FATE server. If you want to submit your
-results be sure to check that your combination of CPU, OS and compiler
-is not already listed on the above mentioned website.
-
-  In the third part you can find a comprehensive listing of FATE makefile
-targets and variables.
-
-
-@chapter Using FATE from your FFmpeg source directory
-
-  If you want to run FATE on your machine you need to have the samples
-in place. You can get the samples via the build target fate-rsync.
-Use this command from the top-level source directory:
-
-@example
-make fate-rsync SAMPLES=fate-suite/
-make fate       SAMPLES=fate-suite/
-@end example
-
-  The above commands set the samples location by passing a makefile
-variable via command line. It is also possible to set the samples
-location at source configuration time by invoking configure with
-`--samples=<path to the samples directory>'. Afterwards you can
-invoke the makefile targets without setting the SAMPLES makefile
-variable. This is illustrated by the following commands:
-
-@example
-./configure --samples=fate-suite/
-make fate-rsync
-make fate
-@end example
-
-  Yet another way to tell FATE about the location of the sample
-directory is by making sure the environment variable FATE_SAMPLES
-contains the path to your samples directory. This can be achieved
-by e.g. putting that variable in your shell profile or by setting
-it in your interactive session.
-
-@example
-FATE_SAMPLES=fate-suite/ make fate
-@end example
-
-@float NOTE
-Do not put a '~' character in the samples path to indicate a home
-directory. Because of shell nuances, this will cause FATE to fail.
-@end float
-
-To use a custom wrapper to run the test, pass @option{--target-exec} to
-@command{configure} or set the @var{TARGET_EXEC} Make variable.
-
-
-@chapter Submitting the results to the FFmpeg result aggregation server
-
-  To submit your results to the server you should run fate through the
-shell script @file{tests/fate.sh} from the FFmpeg sources. This script needs
-to be invoked with a configuration file as its first argument.
-
-@example
-tests/fate.sh /path/to/fate_config
-@end example
-
-  A configuration file template with comments describing the individual
-configuration variables can be found at @file{doc/fate_config.sh.template}.
-
-@ifhtml
-  The mentioned configuration template is also available here:
-@verbatiminclude fate_config.sh.template
-@end ifhtml
-
-  Create a configuration that suits your needs, based on the configuration
-template. The `slot' configuration variable can be any string that is not
-yet used, but it is suggested that you name it adhering to the following
-pattern <arch>-<os>-<compiler>-<compiler version>. The configuration file
-itself will be sourced in a shell script, therefore all shell features may
-be used. This enables you to setup the environment as you need it for your
-build.
-
-  For your first test runs the `fate_recv' variable should be empty or
-commented out. This will run everything as normal except that it will omit
-the submission of the results to the server. The following files should be
-present in $workdir as specified in the configuration file:
-
-@itemize
-    @item configure.log
-    @item compile.log
-    @item test.log
-    @item report
-    @item version
-@end itemize
-
-  When you have everything working properly you can create an SSH key pair
-and send the public key to the FATE server administrator who can be contacted
-at the email address @email{fate-admin@@ffmpeg.org}.
-
-  Configure your SSH client to use public key authentication with that key
-when connecting to the FATE server. Also do not forget to check the identity
-of the server and to accept its host key. This can usually be achieved by
-running your SSH client manually and killing it after you accepted the key.
-The FATE server's fingerprint is:

-@end table
-
-  If you have problems connecting to the FATE server, it may help to try out
-the @command{ssh} command with one or more @option{-v} options. You should
-get detailed output concerning your SSH configuration and the authentication
-process.

+@chapter Introduction
+
+FFmpeg is a very fast video and audio converter. It can also grab from
+a live audio/video source.
+
+The command line interface is designed to be intuitive, in the sense
+that FFmpeg tries to figure out all parameters that can possibly be
+derived automatically. You usually only have to specify the target
+bitrate you want.
+
+FFmpeg can also convert from any sample rate to any other, and resize
+video on the fly with a high quality polyphase filter.
+
+@chapter Quick Start
+
+@c man begin EXAMPLES
+@section Video and Audio grabbing
+
+FFmpeg can grab video and audio from devices given that you specify the input
+format and device.
+
+@example
+ffmpeg -f oss -i /dev/dsp -f video4linux2 -i /dev/video0 /tmp/out.mpg
+@end example
+
+Note that you must activate the right video source and channel before
+launching FFmpeg with any TV viewer such as xawtv
+(@url{http://linux.bytesex.org/xawtv/}) by Gerd Knorr. You also
+have to set the audio recording levels correctly with a
+standard mixer.
+
+@section X11 grabbing
+
+FFmpeg can grab the X11 display.
+
+@example
+ffmpeg -f x11grab -s cif -i :0.0 /tmp/out.mpg
+@end example
+
+0.0 is display.screen number of your X11 server, same as
+the DISPLAY environment variable.
+
+@example
+ffmpeg -f x11grab -s cif -i :0.0+10,20 /tmp/out.mpg
+@end example
+
+0.0 is display.screen number of your X11 server, same as the DISPLAY environment
+variable. 10 is the x-offset and 20 the y-offset for the grabbing.
+
+@section Video and Audio file format conversion
+
+* FFmpeg can use any supported file format and protocol as input:
+
+Examples:
+
+* You can use YUV files as input:
+
+@example
+ffmpeg -i /tmp/test%d.Y /tmp/out.mpg
+@end example
+
+It will use the files:
+@example
+/tmp/test0.Y, /tmp/test0.U, /tmp/test0.V,
+/tmp/test1.Y, /tmp/test1.U, /tmp/test1.V, etc...
+@end example
+
+The Y files use twice the resolution of the U and V files. They are
+raw files, without header. They can be generated by all decent video
+decoders. You must specify the size of the image with the @option{-s} option
+if FFmpeg cannot guess it.
+
+* You can input from a raw YUV420P file:
+
+@example
+ffmpeg -i /tmp/test.yuv /tmp/out.avi
+@end example
+
+test.yuv is a file containing raw YUV planar data. Each frame is composed
+of the Y plane followed by the U and V planes at half vertical and
+horizontal resolution.
+
+* You can output to a raw YUV420P file:
+
+@example
+ffmpeg -i mydivx.avi hugefile.yuv
+@end example
+
+* You can set several input files and output files:
+
+@example
+ffmpeg -i /tmp/a.wav -s 640x480 -i /tmp/a.yuv /tmp/a.mpg
+@end example
+
+Converts the audio file a.wav and the raw YUV video file a.yuv
+to MPEG file a.mpg.
+
+* You can also do audio and video conversions at the same time:
+
+@example
+ffmpeg -i /tmp/a.wav -ar 22050 /tmp/a.mp2
+@end example
+
+Converts a.wav to MPEG audio at 22050 Hz sample rate.
+
+* You can encode to several formats at the same time and define a
+mapping from input stream to output streams:
+
+@example
+ffmpeg -i /tmp/a.wav -ab 64k /tmp/a.mp2 -ab 128k /tmp/b.mp2 -map 0:0 -map 0:0
+@end example
+
+Converts a.wav to a.mp2 at 64 kbits and to b.mp2 at 128 kbits. '-map
+file:index' specifies which input stream is used for each output
+stream, in the order of the definition of output streams.
+
+* You can transcode decrypted VOBs:
+
+@example
+ffmpeg -i snatch_1.vob -f avi -vcodec mpeg4 -b 800k -g 300 -bf 2 -acodec libmp3lame -ab 128k snatch.avi
+@end example
+
+This is a typical DVD ripping example; the input is a VOB file, the
+output an AVI file with MPEG-4 video and MP3 audio. Note that in this
+command we use B-frames so the MPEG-4 stream is DivX5 compatible, and
+GOP size is 300 which means one intra frame every 10 seconds for 29.97fps
+input video. Furthermore, the audio stream is MP3-encoded so you need
+to enable LAME support by passing @code{--enable-libmp3lame} to configure.
+The mapping is particularly useful for DVD transcoding
+to get the desired audio language.
+
+NOTE: To see the supported input formats, use @code{ffmpeg -formats}.
+
+* You can extract images from a video, or create a video from many images:
+
+For extracting images from a video:
+@example
+ffmpeg -i foo.avi -r 1 -s WxH -f image2 foo-%03d.jpeg
+@end example
+
+This will extract one video frame per second from the video and will
+output them in files named @file{foo-001.jpeg}, @file{foo-002.jpeg},
+etc. Images will be rescaled to fit the new WxH values.
+
+If you want to extract just a limited number of frames, you can use the
+above command in combination with the -vframes or -t option, or in
+combination with -ss to start extracting from a certain point in time.
+
+For creating a video from many images:
+@example
+ffmpeg -f image2 -i foo-%03d.jpeg -r 12 -s WxH foo.avi
+@end example
+
+The syntax @code{foo-%03d.jpeg} specifies to use a decimal number
+composed of three digits padded with zeroes to express the sequence
+number. It is the same syntax supported by the C printf function, but
+only formats accepting a normal integer are suitable.
+
+* You can put many streams of the same type in the output:
+
+@example
+ffmpeg -i test1.avi -i test2.avi -vcodec copy -acodec copy -vcodec copy -acodec copy test12.avi -newvideo -newaudio
+@end example
+
+In addition to the first video and audio streams, the resulting
+output file @file{test12.avi} will contain the second video
+and the second audio stream found in the input streams list.
+
+The @code{-newvideo}, @code{-newaudio} and @code{-newsubtitle}
+options have to be specified immediately after the name of the output
+file to which you want to add them.

+@chapter Invocation
+
+@section Syntax
+
+The generic syntax is:
+
+@example
+@c man begin SYNOPSIS
+ffmpeg [[infile options][@option{-i} @var{infile}]]... @{[outfile options] @var{outfile}@}...
+@c man end
+@end example
+@c man begin DESCRIPTION
+As a general rule, options are applied to the next specified
+file. Therefore, order is important, and you can have the same
+option on the command line multiple times. Each occurrence is
+then applied to the next input or output file.
+
+* To set the video bitrate of the output file to 64kbit/s:
+@example
+ffmpeg -i input.avi -b 64k output.avi
+@end example
+
+* To force the frame rate of the output file to 24 fps:
+@example
+ffmpeg -i input.avi -r 24 output.avi
+@end example
+
+* To force the frame rate of the input file (valid for raw formats only)
+to 1 fps and the frame rate of the output file to 24 fps:
+@example
+ffmpeg -r 1 -i input.m2v -r 24 output.avi
+@end example
+
+The format option may be needed for raw input files.
+
+By default, FFmpeg tries to convert as losslessly as possible: It
+uses the same audio and video parameters for the outputs as the one
+specified for the inputs.

+Disable video recording.
+@item -bt @var{tolerance}
+Set video bitrate tolerance (in bits, default 4000k).
+Has a minimum value of: (target_bitrate/target_framerate).
+In 1-pass mode, bitrate tolerance specifies how far ratecontrol is
+willing to deviate from the target average bitrate value. This is
+not related to min/max bitrate. Lowering tolerance too much has
+an adverse effect on quality.
+@item -maxrate @var{bitrate}
+Set max video bitrate (in bit/s).
+Requires -bufsize to be set.
+@item -minrate @var{bitrate}
+Set min video bitrate (in bit/s).

+@example
+ffmpeg -i myfile.avi -b 4000k -minrate 4000k -maxrate 4000k -bufsize 1835k out.m2v
+@end example
+It is of little use elsewise.
+@item -bufsize @var{size}

+Select the pass number (1 or 2). It is used to do two-pass
+video encoding. The statistics of the video are recorded in the first
+pass into a log file (see also the option -passlogfile),
+and in the second pass that log file is used to generate the video
+at the exact requested bitrate.
+On pass 1, you may just deactivate audio and set output to null,
+examples for Windows and Unix:
+@example
+ffmpeg -i foo.mov -vcodec libxvid -pass 1 -an -f rawvideo -y NUL
+ffmpeg -i foo.mov -vcodec libxvid -pass 1 -an -f rawvideo -y /dev/null
+@end example
+
+@item -passlogfile @var{prefix}
+Set two-pass log file name prefix to @var{prefix}, the default file name
+prefix is ``ffmpeg2pass''. The complete file name will be

+@end table
+
+@section Preset files
+
+A preset file contains a sequence of @var{option}=@var{value} pairs,
+one for each line, specifying a sequence of options which would be
+awkward to specify on the command line. Lines starting with the hash
+('#') character are ignored and are used to provide comments. Check
+the @file{ffpresets} directory in the FFmpeg source tree for examples.
+
+Preset files are specified with the @code{vpre}, @code{apre} and
+@code{spre} options. The options specified in a preset file are
+applied to the currently selected codec of the same type as the preset
+option.
+
+The argument passed to the preset options identifies the preset file
+to use according to the following rules.
+
+First ffmpeg searches for a file named @var{arg}.ffpreset in the
+directories @file{$HOME/.ffmpeg}, and in the datadir defined at
+configuration time (usually @file{PREFIX/share/ffmpeg}) in that
+order. For example, if the argument is @code{libx264-max}, it will
+search for the file @file{libx264-max.ffpreset}.
+
+If no such file is found, then ffmpeg will search for a file named
+@var{codec_name}-@var{arg}.ffpreset in the above-mentioned
+directories, where @var{codec_name} is the name of the codec to which
+the preset file options will be applied. For example, if you select
+the video codec with @code{-vcodec libx264} and use @code{-vpre max},
+then it will search for the file @file{libx264-max.ffpreset}.
+
+Finally, if the above rules failed and the argument specifies an
+absolute pathname, ffmpeg will search for that filename. This way you
+can specify the absolute and complete filename of the preset file, for
+example @file{./ffpresets/libx264-max.ffpreset}.

+@section Protocols
+
+The file name can be @file{-} to read from standard input or to write
+to standard output.
+
+FFmpeg also handles many protocols specified with an URL syntax.
+
+Use 'ffmpeg -formats' to see a list of the supported protocols.
+
+The protocol @code{http:} is currently used only to communicate with
+FFserver (see the FFserver documentation). When FFmpeg will be a
+video player it will also be used for streaming :-)
+
+@chapter Tips
+
+@itemize
+@item For streaming at very low bitrate application, use a low frame rate
+and a small GOP size. This is especially true for RealVideo where
+the Linux player does not seem to be very fast, so it can miss
+frames. An example is:
+
+@example
+ffmpeg -g 3 -r 3 -t 10 -b 50k -s qcif -f rv10 /tmp/b.rm
+@end example
+
+@item  The parameter 'q' which is displayed while encoding is the current
+quantizer. The value 1 indicates that a very good quality could
+be achieved. The value 31 indicates the worst quality. If q=31 appears
+too often, it means that the encoder cannot compress enough to meet
+your bitrate. You must either increase the bitrate, decrease the
+frame rate or decrease the frame size.
+
+@item If your computer is not fast enough, you can speed up the
+compression at the expense of the compression ratio. You can use
+'-me zero' to speed up motion estimation, and '-intra' to disable
+motion estimation completely (you have only I-frames, which means it
+is about as good as JPEG compression).
+
+@item To have very low audio bitrates, reduce the sampling frequency
+(down to 22050 Hz for MPEG audio, 22050 or 11025 for AC-3).
+
+@item To have a constant quality (but a variable bitrate), use the option
+'-qscale n' when 'n' is between 1 (excellent quality) and 31 (worst
+quality).
+
+@item When converting video files, you can use the '-sameq' option which
+uses the same quality factor in the encoder as in the decoder.
+It allows almost lossless encoding.

+FFmpeg & evaluating performance on the PowerPC Architecture HOWTO
+
+(c) 2003-2004 Romain Dolbeau <romain@dolbeau.org>
+
+
+
+I - Introduction
+
+The PowerPC architecture and its SIMD extension AltiVec offer some
+interesting tools to evaluate performance and improve the code.
+This document tries to explain how to use those tools with FFmpeg.
+
+The architecture itself offers two ways to evaluate the performance of
+a given piece of code:
+
+1) The Time Base Registers (TBL)
+2) The Performance Monitor Counter Registers (PMC)
+
+The first ones are always available, always active, but they're not very
+accurate: the registers increment by one every four *bus* cycles. On
+my 667 Mhz tiBook (ppc7450), this means once every twenty *processor*
+cycles. So we won't use that.
+
+The PMC are much more useful: not only can they report cycle-accurate
+timing, but they can also be used to monitor many other parameters,
+such as the number of AltiVec stalls for every kind of instruction,
+or instruction cache misses. The downside is that not all processors
+support the PMC (all G3, all G4 and the 970 do support them), and
+they're inactive by default - you need to activate them with a
+dedicated tool. Also, the number of available PMC depends on the
+procesor: the various 604 have 2, the various 75x (aka. G3) have 4,
+and the various 74xx (aka G4) have 6.
+
+*WARNING*: The PowerPC 970 is not very well documented, and its PMC
+registers are 64 bits wide. To properly notify the code, you *must*
+tune for the 970 (using --tune=970), or the code will assume 32 bit
+registers.
+
+
+II - Enabling FFmpeg PowerPC performance support
+
+This needs to be done by hand. First, you need to configure FFmpeg as
+usual, but add the "--powerpc-perf-enable" option. For instance:
+
+#####
+./configure --prefix=/usr/local/ffmpeg-svn --cc=gcc-3.3 --tune=7450 --powerpc-perf-enable
+#####
+
+This will configure FFmpeg to install inside /usr/local/ffmpeg-svn,
+compiling with gcc-3.3 (you should try to use this one or a newer
+gcc), and tuning for the PowerPC 7450 (i.e. the newer G4; as a rule of
+thumb, those at 550Mhz and more). It will also enable the PMC.
+
+You may also edit the file "config.h" to enable the following line:
+
+#####
+// #define ALTIVEC_USE_REFERENCE_C_CODE 1
+#####
+
+If you enable this line, then the code will not make use of AltiVec,
+but will use the reference C code instead. This is useful to compare
+performance between two versions of the code.
+
+Also, the number of enabled PMC is defined in "libavcodec/ppc/dsputil_ppc.h":
+
+#####
+#define POWERPC_NUM_PMC_ENABLED 4
+#####
+
+If you have a G4 CPU, you can enable all 6 PMC. DO NOT enable more
+PMC than available on your CPU!
+
+Then, simply compile FFmpeg as usual (make && make install).
+
+
+
+III - Using FFmpeg PowerPC performance support
+
+This FFmeg can be used exactly as usual. But before exiting, FFmpeg
+will dump a per-function report that looks like this:
+
+#####
+PowerPC performance report
+ Values are from the PMC registers, and represent whatever the
+ registers are set to record.
+ Function "gmc1_altivec" (pmc1):
+        min: 231
+        max: 1339867
+        avg: 558.25 (255302)
+ Function "gmc1_altivec" (pmc2):
+        min: 93
+        max: 2164
+        avg: 267.31 (255302)
+ Function "gmc1_altivec" (pmc3):
+        min: 72
+        max: 1987
+        avg: 276.20 (255302)
+(...)
+#####
+
+In this example, PMC1 was set to record CPU cycles, PMC2 was set to
+record AltiVec Permute Stall Cycles, and PMC3 was set to record AltiVec
+Issue Stalls.
+
+The function "gmc1_altivec" was monitored 255302 times, and the
+minimum execution time was 231 processor cycles. The max and average
+aren't much use, as it's very likely the OS interrupted execution for
+reasons of its own :-(
+
+With the exact same settings and source file, but using the reference C
+code we get:
+
+#####
+PowerPC performance report
+ Values are from the PMC registers, and represent whatever the
+ registers are set to record.
+ Function "gmc1_altivec" (pmc1):
+        min: 592
+        max: 2532235
+        avg: 962.88 (255302)
+ Function "gmc1_altivec" (pmc2):
+        min: 0
+        max: 33
+        avg: 0.00 (255302)
+ Function "gmc1_altivec" (pmc3):
+        min: 0
+        max: 350
+        avg: 0.03 (255302)
+(...)
+#####
+
+592 cycles, so the fastest AltiVec execution is about 2.5x faster than
+the fastest C execution in this example. It's not perfect but it's not
+bad (well I wrote this function so I can't say otherwise :-).
+
+Once you have that kind of report, you can try to improve things by
+finding what goes wrong and fixing it; in the example above, one
+should try to diminish the number of AltiVec stalls, as this *may*
+improve performance.
+
+
+
+IV) Enabling the PMC in Mac OS X
+
+This is easy. Use "Monster" and "monster". Those tools come from
+Apple's CHUD package, and can be found hidden in the developer web
+site & FTP site. "MONster" is the graphical application, use it to
+generate a config file specifying what each register should
+monitor. Then use the command-line application "monster" to use that
+config file, and enjoy the results.
+
+Note that "MONster" can be used for many other things, but it's
+documented by Apple, it's not my subject.
+
+If you are using CHUD 4.4.2 or later, you'll notice that MONster is
+no longer available. It's been superseeded by Shark, where
+configuration of PMCs is available as a plugin.
+
+
+
+V) Enabling the PMC on Linux
+
+On linux you may use oprofile from http://oprofile.sf.net, depending on the
+version and the cpu you may need to apply a patch[1] to access a set of the
+possibile counters from the userspace application. You can always define them
+using the kernel interface /dev/oprofile/* .

-@chapter Description
-@c man begin DESCRIPTION
-
-ffprobe gathers information from multimedia streams and prints it in
-human- and machine-readable fashion.
-
-For example it can be used to check the format of the container used
-by a multimedia stream and the format and type of each media stream
-contained in it.
-
-If a filename is specified in input, ffprobe will try to open and
-probe the file content. If the file cannot be opened or recognized as
-a multimedia file, a positive exit code is returned.
-
-ffprobe may be employed both as a standalone application or in
-combination with a textual filter, which may perform more
-sophisticated processing, e.g. statistical processing or plotting.
-
-Options are used to list some of the formats supported by ffprobe or
-for specifying which information to display, and for setting how
-ffprobe will show it.
-
-ffprobe output is designed to be easily parsable by a textual filter,
-and consists of one or more sections of a form defined by the selected
-writer, which is specified by the @option{print_format} option.
-
-Sections may contain other nested sections, and are identified by a
-name (which may be shared by other sections), and an unique
-name. See the output of @option{sections}.
-
-Metadata tags stored in the container or in the streams are recognized
-and printed in the corresponding "FORMAT", "STREAM" or "PROGRAM_STREAM"
-section.

-than once, then all specified entries will be shown.
-
-This option is deprecated, use @code{show_entries} instead.
-
-@item -show_entries @var{section_entries}
-Set list of entries to show.
-
-Entries are specified according to the following
-syntax. @var{section_entries} contains a list of section entries
-separated by @code{:}. Each section entry is composed by a section
-name (or unique name), optionally followed by a list of entries local
-to that section, separated by @code{,}.
-
-If section name is specified but is followed by no @code{=}, all
-entries are printed to output, together with all the contained
-sections. Otherwise only the entries specified in the local section
-entries list are printed. In particular, if @code{=} is specified but
-the list of local entries is empty, then no entries will be shown for
-that section.
-
-Note that the order of specification of the local section entries is
-not honored in the output, and the usual display order will be
-retained.
-
-The formal syntax is given by:
-@example
-@var{LOCAL_SECTION_ENTRIES} ::= @var{SECTION_ENTRY_NAME}[,@var{LOCAL_SECTION_ENTRIES}]
-@var{SECTION_ENTRY}         ::= @var{SECTION_NAME}[=[@var{LOCAL_SECTION_ENTRIES}]]
-@var{SECTION_ENTRIES}       ::= @var{SECTION_ENTRY}[:@var{SECTION_ENTRIES}]
-@end example
-
-For example, to show only the index and type of each stream, and the PTS
-time, duration time, and stream index of the packets, you can specify
-the argument:
-@example
-packet=pts_time,duration_time,stream_index : stream=index,codec_type
-@end example
-
-To show all the entries in the section "format", but only the codec
-type in the section "stream", specify the argument:
-@example
-format : stream=codec_type
-@end example
-
-To show all the tags in the stream and format sections:
-@example
-format_tags : format_tags
-@end example
-
-To show only the @code{title} tag (if available) in the stream
-sections:
-@example
-stream_tags=title
-@end example
-
-@item -show_packets
-Show information about each packet contained in the input multimedia
-stream.
-
-The information for each single packet is printed within a dedicated
-section with name "PACKET".
-
-@item -show_frames
-Show information about each frame and subtitle contained in the input
-multimedia stream.
-
-The information for each single frame is printed within a dedicated
-section with name "FRAME" or "SUBTITLE".
-
-@item -show_streams
-Show information about each media stream contained in the input
-multimedia stream.
-
-Each media stream information is printed within a dedicated section
-with name "STREAM".
-
-@item -show_programs
-Show information about programs and their streams contained in the input
-multimedia stream.
-
-Each media stream information is printed within a dedicated section
-with name "PROGRAM_STREAM".
-
-@item -show_chapters
-Show information about chapters stored in the format.
-
-Each chapter is printed within a dedicated section with name "CHAPTER".
-
-@item -count_frames
-Count the number of frames per stream and report it in the
-corresponding stream section.
-
-@item -count_packets
-Count the number of packets per stream and report it in the
-corresponding stream section.
-
-@item -read_intervals @var{read_intervals}
-
-Read only the specified intervals. @var{read_intervals} must be a
-sequence of interval specifications separated by ",".
-@command{ffprobe} will seek to the interval starting point, and will
-continue reading from that.
-
-Each interval is specified by two optional parts, separated by "%".
-
-The first part specifies the interval start position. It is
-interpreted as an abolute position, or as a relative offset from the
-current position if it is preceded by the "+" character. If this first
-part is not specified, no seeking will be performed when reading this
-interval.
-
-The second part specifies the interval end position. It is interpreted
-as an absolute position, or as a relative offset from the current
-position if it is preceded by the "+" character. If the offset
-specification starts with "#", it is interpreted as the number of
-packets to read (not including the flushing packets) from the interval
-start. If no second part is specified, the program will read until the
-end of the input.
-
-Note that seeking is not accurate, thus the actual interval start
-point may be different from the specified position. Also, when an
-interval duration is specified, the absolute end time will be computed
-by adding the duration to the interval start point found by seeking
-the file, rather than to the specified start value.
-
-The formal syntax is given by:
-@example
-@var{INTERVAL}  ::= [@var{START}|+@var{START_OFFSET}][%[@var{END}|+@var{END_OFFSET}]]
-@var{INTERVALS} ::= @var{INTERVAL}[,@var{INTERVALS}]
-@end example
-
-A few examples follow.
-@itemize
-@item
-Seek to time 10, read packets until 20 seconds after the found seek
-point, then seek to position @code{01:30} (1 minute and thirty
-seconds) and read packets until position @code{01:45}.
-@example
-10%+20,01:30%01:45
-@end example
-
-@item
-Read only 42 packets after seeking to position @code{01:23}:
-@example
-01:23%+#42
-@end example
-
-@item
-Read only the first 20 seconds from the start:
-@example
-%+20
-@end example
-
-@item
-Read from the start until position @code{02:30}:
-@example
-%02:30
-@end example
-@end itemize
-
-@item -show_private_data, -private
-Show private data, that is data depending on the format of the
-particular shown element.
-This option is enabled by default, but you may need to disable it
-for specific uses, for example when creating XSD-compliant XML output.

-Show information related to program version.
-
-Version information is printed within a section with name

-Force bitexact output, useful to produce output which is not dependent
-on the specific build.
-

-@chapter Writers
-@c man begin WRITERS
-
-A writer defines the output format adopted by @command{ffprobe}, and will be
-used for printing all the parts of the output.
-
-A writer may accept one or more arguments, which specify the options
-to adopt. The options are specified as a list of @var{key}=@var{value}
-pairs, separated by ":".
-
-All writers support the following options:
-
-@table @option
-@item string_validation, sv
-Set string validation mode.
-
-The following values are accepted.
-@table @samp
-@item fail
-The writer will fail immediately in case an invalid string (UTF-8)
-sequence or code point is found in the input. This is especially
-useful to validate input metadata.
-
-@item ignore
-Any validation error will be ignored. This will result in possibly
-broken output, especially with the json or xml writer.
-
-@item replace
-The writer will substitute invalid UTF-8 sequences or code points with
-the string specified with the @option{string_validation_replacement}.
-@end table
-
-Default value is @samp{replace}.
-
-@item string_validation_replacement, svr
-Set replacement string to use in case @option{string_validation} is
-set to @samp{replace}.
-
-In case the option is not specified, the writer will assume the empty
-string, that is it will remove the invalid sequences from the input
-strings.
-@end table
-
-A description of the currently available writers follows.
-
-@section default
-Default format.
-
-Print each section in the form:
-@example
-[SECTION]
-key1=val1
-...
-keyN=valN
-[/SECTION]
-@end example
-
-Metadata tags are printed as a line in the corresponding FORMAT, STREAM or
-PROGRAM_STREAM section, and are prefixed by the string "TAG:".
-
-A description of the accepted options follows.
-
-@table @option
-
-@item nokey, nk
-If set to 1 specify not to print the key of each field. Default value
-is 0.
-
-@item noprint_wrappers, nw
-If set to 1 specify not to print the section header and footer.
-Default value is 0.
-@end table
-
-@section compact, csv
-Compact and CSV format.
-
-The @code{csv} writer is equivalent to @code{compact}, but supports
-different defaults.
-
-Each section is printed on a single line.
-If no option is specifid, the output has the form:
-@example
-section|key1=val1| ... |keyN=valN
-@end example
-
-Metadata tags are printed in the corresponding "format" or "stream"
-section. A metadata tag key, if printed, is prefixed by the string
-"tag:".
-
-The description of the accepted options follows.
-
-@table @option
-
-@item item_sep, s

-If set to 1 specify not to print the key of each field. Its default
-value is 0 (1 for the @code{csv} writer).
-
-@item escape, e
-Set the escape mode to use, default to "c" ("csv" for the @code{csv}
-writer).
-
-It can assume one of the following values:
-@table @option
-@item c
-Perform C-like escaping. Strings containing a newline ('\n'), carriage
-return ('\r'), a tab ('\t'), a form feed ('\f'), the escaping
-character ('\') or the item separator character @var{SEP} are escaped using C-like fashioned
-escaping, so that a newline is converted to the sequence "\n", a
-carriage return to "\r", '\' to "\\" and the separator @var{SEP} is
-converted to "\@var{SEP}".
-
-@item csv
-Perform CSV-like escaping, as described in RFC4180.  Strings
-containing a newline ('\n'), a carriage return ('\r'), a double quote
-('"'), or @var{SEP} are enclosed in double-quotes.
-
-@item none
-Perform no escaping.
-@end table
-
-@item print_section, p

-@end table
-
-@section flat
-Flat format.
-
-A free-form output where each line contains an explicit key=value, such as
-"streams.stream.3.tags.foo=bar". The output is shell escaped, so it can be

-chapter. A value of 0 will disable this behavior.
-
-Default value is 1.
-@end table
-
-@section ini
-INI format output.
-
-Print output in an INI based format.
-
-The following conventions are adopted:
-
-@itemize
-@item
-all key and values are UTF-8
-@item

-JSON based format.
-
-Each section is printed using JSON notation.
-
-The description of the accepted options follows.
-
-@table @option
-
-@item compact, c
-If set to 1 enable compact output, that is each section will be
-printed on a single line. Default value is 0.

+@chapter Introduction
+
+@c man begin DESCRIPTION
+FFserver is a streaming server for both audio and video. It supports
+several live feeds, streaming from files and time shifting on live feeds
+(you can seek to positions in the past on each live feed, provided you
+specify a big enough feed storage in ffserver.conf).
+
+FFserver runs in daemon mode by default; that is, it puts itself in
+the background and detaches from its TTY, unless it is launched in
+debug mode or a NoDaemon option is specified in the configuration
+file.
+
+This documentation covers only the streaming aspects of ffserver /
+ffmpeg. All questions about parameters for ffmpeg, codec questions,
+etc. are not covered here. Read @file{ffmpeg-doc.html} for more
+information.
+
+@section How does it work?
+
+FFserver receives prerecorded files or FFM streams from some ffmpeg
+instance as input, then streams them over RTP/RTSP/HTTP.
+
+An ffserver instance will listen on some port as specified in the
+configuration file. You can launch one or more instances of ffmpeg and
+send one or more FFM streams to the port where ffserver is expecting
+to receive them. Alternately, you can make ffserver launch such ffmpeg
+instances at startup.
+
+Input streams are called feeds, and each one is specified by a <Feed>
+section in the configuration file.
+
+For each feed you can have different output streams in various
+formats, each one specified by a <Stream> section in the configuration
+file.
+
+@section Status stream
+
+FFserver supports an HTTP interface which exposes the current status
+of the server.
+
+Simply point your browser to the address of the special status stream
+specified in the configuration file.
+
+For example if you have:
+@example
+<Stream status.html>
+Format status
+
+# Only allow local people to get the status
+ACL allow localhost
+ACL allow 192.168.0.0 192.168.255.255
+</Stream>
+@end example
+
+then the server will post a page with the status information when
+the special stream @file{status.html} is requested.
+
+@section What can this do?
+
+When properly configured and running, you can capture video and audio in real
+time from a suitable capture card, and stream it out over the Internet to
+either Windows Media Player or RealAudio player (with some restrictions).
+
+It can also stream from files, though that is currently broken. Very often, a
+web server can be used to serve up the files just as well.
+
+It can stream prerecorded video from .ffm files, though it is somewhat tricky
+to make it work correctly.
+
+@section What do I need?
+
+I use Linux on a 900 MHz Duron with a cheapo Bt848 based TV capture card. I'm
+using stock Linux 2.4.17 with the stock drivers. [Actually that isn't true,
+I needed some special drivers for my motherboard-based sound card.]
+
+I understand that FreeBSD systems work just fine as well.
+
+@section How do I make it work?
+
+First, build the kit. It *really* helps to have installed LAME first. Then when
+you run the ffserver ./configure, make sure that you have the
+@code{--enable-libmp3lame} flag turned on.
+
+LAME is important as it allows for streaming audio to Windows Media Player.
+Don't ask why the other audio types do not work.
+
+As a simple test, just run the following two command lines where INPUTFILE
+is some file which you can decode with ffmpeg:
+
+@example
+./ffserver -f doc/ffserver.conf &
+./ffmpeg -i INPUTFILE http://localhost:8090/feed1.ffm
+@end example
+
+At this point you should be able to go to your Windows machine and fire up
+Windows Media Player (WMP). Go to Open URL and enter
+
+@example
+    http://<linuxbox>:8090/test.asf
+@end example
+
+You should (after a short delay) see video and hear audio.
+
+WARNING: trying to stream test1.mpg doesn't work with WMP as it tries to
+transfer the entire file before starting to play.
+The same is true of AVI files.
+
+@section What happens next?
+
+You should edit the ffserver.conf file to suit your needs (in terms of
+frame rates etc). Then install ffserver and ffmpeg, write a script to start
+them up, and off you go.
+
+@section Troubleshooting
+
+@subsection I don't hear any audio, but video is fine.
+
+Maybe you didn't install LAME, or got your ./configure statement wrong. Check
+the ffmpeg output to see if a line referring to MP3 is present. If not, then
+your configuration was incorrect. If it is, then maybe your wiring is not
+set up correctly. Maybe the sound card is not getting data from the right
+input source. Maybe you have a really awful audio interface (like I do)
+that only captures in stereo and also requires that one channel be flipped.
+If you are one of these people, then export 'AUDIO_FLIP_LEFT=1' before
+starting ffmpeg.
+
+@subsection The audio and video loose sync after a while.
+
+Yes, they do.
+
+@subsection After a long while, the video update rate goes way down in WMP.
+
+Yes, it does. Who knows why?
+
+@subsection WMP 6.4 behaves differently to WMP 7.
+
+Yes, it does. Any thoughts on this would be gratefully received. These
+differences extend to embedding WMP into a web page. [There are two
+object IDs that you can use: The old one, which does not play well, and
+the new one, which does (both tested on the same system). However,
+I suspect that the new one is not available unless you have installed WMP 7].
+
+@section What else can it do?
+
+You can replay video from .ffm files that was recorded earlier.
+However, there are a number of caveats, including the fact that the
+ffserver parameters must match the original parameters used to record the
+file. If they do not, then ffserver deletes the file before recording into it.
+(Now that I write this, it seems broken).
+
+You can fiddle with many of the codec choices and encoding parameters, and
+there are a bunch more parameters that you cannot control. Post a message
+to the mailing list if there are some 'must have' parameters. Look in
+ffserver.conf for a list of the currently available controls.
+
+It will automatically generate the ASX or RAM files that are often used
+in browsers. These files are actually redirections to the underlying ASF
+or RM file. The reason for this is that the browser often fetches the
+entire file before starting up the external viewer. The redirection files
+are very small and can be transferred quickly. [The stream itself is
+often 'infinite' and thus the browser tries to download it and never
+finishes.]
+
+@section Tips
+
+* When you connect to a live stream, most players (WMP, RA, etc) want to
+buffer a certain number of seconds of material so that they can display the
+signal continuously. However, ffserver (by default) starts sending data
+in realtime. This means that there is a pause of a few seconds while the
+buffering is being done by the player. The good news is that this can be
+cured by adding a '?buffer=5' to the end of the URL. This means that the
+stream should start 5 seconds in the past -- and so the first 5 seconds
+of the stream are sent as fast as the network will allow. It will then
+slow down to real time. This noticeably improves the startup experience.
+
+You can also add a 'Preroll 15' statement into the ffserver.conf that will
+add the 15 second prebuffering on all requests that do not otherwise
+specify a time. In addition, ffserver will skip frames until a key_frame
+is found. This further reduces the startup delay by not transferring data
+that will be discarded.
+
+* You may want to adjust the MaxBandwidth in the ffserver.conf to limit
+the amount of bandwidth consumed by live streams.
+
+@section Why does the ?buffer / Preroll stop working after a time?
+
+It turns out that (on my machine at least) the number of frames successfully
+grabbed is marginally less than the number that ought to be grabbed. This
+means that the timestamp in the encoded data stream gets behind realtime.
+This means that if you say 'Preroll 10', then when the stream gets 10
+or more seconds behind, there is no Preroll left.
+
+Fixing this requires a change in the internals of how timestamps are
+handled.
+
+@section Does the @code{?date=} stuff work.
+
+Yes (subject to the limitation outlined above). Also note that whenever you
+start ffserver, it deletes the ffm file (if any parameters have changed),
+thus wiping out what you had recorded before.
+
+The format of the @code{?date=xxxxxx} is fairly flexible. You should use one
+of the following formats (the 'T' is literal):
+
+@example
+* YYYY-MM-DDTHH:MM:SS     (localtime)
+* YYYY-MM-DDTHH:MM:SSZ    (UTC)
+@end example
+
+You can omit the YYYY-MM-DD, and then it refers to the current day. However
+note that @samp{?date=16:00:00} refers to 16:00 on the current day -- this
+may be in the future and so is unlikely to be useful.
+
+You use this by adding the ?date= to the end of the URL for the stream.
+For example:   @samp{http://localhost:8080/test.asf?date=2002-07-26T23:05:00}.

-
-@chapter Detailed description
-
-@command{ffserver} works by forwarding streams encoded by
-@command{ffmpeg}, or pre-recorded streams which are read from disk.
-
-Precisely, @command{ffserver} acts as an HTTP server, accepting POST
-requests from @command{ffmpeg} to acquire the stream to publish, and
-serving RTSP clients or HTTP clients GET requests with the stream
-media content.
-
-A feed is an @ref{FFM} stream created by @command{ffmpeg}, and sent to
-a port where @command{ffserver} is listening.
-
-Each feed is identified by a unique name, corresponding to the name
-of the resource published on @command{ffserver}, and is configured by
-a dedicated @code{Feed} section in the configuration file.
-
-The feed publish URL is given by:
-@example
-http://@var{ffserver_ip_address}:@var{http_port}/@var{feed_name}
-@end example
-
-where @var{ffserver_ip_address} is the IP address of the machine where
-@command{ffserver} is installed, @var{http_port} is the port number of
-the HTTP server (configured through the @option{Port} option), and
-@var{feed_name} is the name of the corresponding feed defined in the
-configuration file.
-
-Each feed is associated to a file which is stored on disk. This stored
-file is used to allow to send pre-recorded data to a player as fast as
-possible when new content is added in real-time to the stream.
-
-A "live-stream" or "stream" is a resource published by
-@command{ffserver}, and made accessible through the HTTP protocol to
-clients.
-
-A stream can be connected to a feed, or to a file. In the first case,
-the published stream is forwarded from the corresponding feed
-generated by a running instance of @command{ffmpeg}, in the second
-case the stream is read from a pre-recorded file.
-
-Each stream is identified by a unique name, corresponding to the name
-of the resource served by @command{ffserver}, and is configured by
-a dedicated @code{Stream} section in the configuration file.
-
-The stream access HTTP URL is given by:
-@example
-http://@var{ffserver_ip_address}:@var{http_port}/@var{stream_name}[@var{options}]
-@end example
-
-The stream access RTSP URL is given by:
-@example
-http://@var{ffserver_ip_address}:@var{rtsp_port}/@var{stream_name}[@var{options}]
-@end example
-
-@var{stream_name} is the name of the corresponding stream defined in
-the configuration file. @var{options} is a list of options specified
-after the URL which affects how the stream is served by
-@command{ffserver}. @var{http_port} and @var{rtsp_port} are the HTTP
-and RTSP ports configured with the options @var{Port} and
-@var{RTSPPort} respectively.
-
-In case the stream is associated to a feed, the encoding parameters
-must be configured in the stream configuration. They are sent to
-@command{ffmpeg} when setting up the encoding. This allows
-@command{ffserver} to define the encoding parameters used by
-the @command{ffmpeg} encoders.
-
-The @command{ffmpeg} @option{override_ffserver} commandline option
-allows one to override the encoding parameters set by the server.
-
-Multiple streams can be connected to the same feed.
-
-For example, you can have a situation described by the following
-graph:
-@example
-               _________       __________
-              |         |     |          |

-@anchor{FFM}
-@section FFM, FFM2 formats
-
-FFM and FFM2 are formats used by ffserver. They allow storing a wide variety of
-video and audio streams and encoding options, and can store a moving time segment
-of an infinite movie or a whole movie.
-
-FFM is version specific, and there is limited compatibility of FFM files
-generated by one version of ffmpeg/ffserver and another version of
-ffmpeg/ffserver. It may work but it is not guaranteed to work.
-
-FFM2 is extensible while maintaining compatibility and should work between
-differing versions of tools. FFM2 is the default.
-
-@section Status stream
-
-@command{ffserver} supports an HTTP interface which exposes the
-current status of the server.
-
-Simply point your browser to the address of the special status stream
-specified in the configuration file.
-
-For example if you have:
-@example
-<Stream status.html>
-Format status
-
-# Only allow local people to get the status
-ACL allow localhost
-ACL allow 192.168.0.0 192.168.255.255
-</Stream>
-@end example
-
-then the server will post a page with the status information when
-the special stream @file{status.html} is requested.
-
-@section How do I make it work?
-
-As a simple test, just run the following two command lines where INPUTFILE
-is some file which you can decode with ffmpeg:
-
-@example
-ffserver -f doc/ffserver.conf &
-ffmpeg -i INPUTFILE http://localhost:8090/feed1.ffm
-@end example
-
-At this point you should be able to go to your Windows machine and fire up
-Windows Media Player (WMP). Go to Open URL and enter
-
-@example
-    http://<linuxbox>:8090/test.asf
-@end example
-
-You should (after a short delay) see video and hear audio.
-
-WARNING: trying to stream test1.mpg doesn't work with WMP as it tries to
-transfer the entire file before starting to play.
-The same is true of AVI files.
-
-@section What happens next?
-
-You should edit the ffserver.conf file to suit your needs (in terms of
-frame rates etc). Then install ffserver and ffmpeg, write a script to start
-them up, and off you go.
-
-@section What else can it do?
-
-You can replay video from .ffm files that was recorded earlier.
-However, there are a number of caveats, including the fact that the
-ffserver parameters must match the original parameters used to record the
-file. If they do not, then ffserver deletes the file before recording into it.
-(Now that I write this, it seems broken).
-
-You can fiddle with many of the codec choices and encoding parameters, and
-there are a bunch more parameters that you cannot control. Post a message
-to the mailing list if there are some 'must have' parameters. Look in
-ffserver.conf for a list of the currently available controls.
-
-It will automatically generate the ASX or RAM files that are often used
-in browsers. These files are actually redirections to the underlying ASF
-or RM file. The reason for this is that the browser often fetches the
-entire file before starting up the external viewer. The redirection files
-are very small and can be transferred quickly. [The stream itself is
-often 'infinite' and thus the browser tries to download it and never
-finishes.]
-
-@section Tips
-
-* When you connect to a live stream, most players (WMP, RA, etc) want to
-buffer a certain number of seconds of material so that they can display the
-signal continuously. However, ffserver (by default) starts sending data
-in realtime. This means that there is a pause of a few seconds while the
-buffering is being done by the player. The good news is that this can be
-cured by adding a '?buffer=5' to the end of the URL. This means that the
-stream should start 5 seconds in the past -- and so the first 5 seconds
-of the stream are sent as fast as the network will allow. It will then
-slow down to real time. This noticeably improves the startup experience.
-
-You can also add a 'Preroll 15' statement into the ffserver.conf that will
-add the 15 second prebuffering on all requests that do not otherwise
-specify a time. In addition, ffserver will skip frames until a key_frame
-is found. This further reduces the startup delay by not transferring data
-that will be discarded.
-
-@section Why does the ?buffer / Preroll stop working after a time?
-
-It turns out that (on my machine at least) the number of frames successfully
-grabbed is marginally less than the number that ought to be grabbed. This
-means that the timestamp in the encoded data stream gets behind realtime.
-This means that if you say 'Preroll 10', then when the stream gets 10
-or more seconds behind, there is no Preroll left.
-
-Fixing this requires a change in the internals of how timestamps are
-handled.
-
-@section Does the @code{?date=} stuff work.
-
-Yes (subject to the limitation outlined above). Also note that whenever you
-start ffserver, it deletes the ffm file (if any parameters have changed),
-thus wiping out what you had recorded before.
-
-The format of the @code{?date=xxxxxx} is fairly flexible. You should use one
-of the following formats (the 'T' is literal):
-
-@example
-* YYYY-MM-DDTHH:MM:SS     (localtime)
-* YYYY-MM-DDTHH:MM:SSZ    (UTC)
-@end example
-
-You can omit the YYYY-MM-DD, and then it refers to the current day. However
-note that @samp{?date=16:00:00} refers to 16:00 on the current day -- this
-may be in the future and so is unlikely to be useful.
-
-You use this by adding the ?date= to the end of the URL for the stream.
-For example:   @samp{http://localhost:8080/test.asf?date=2002-07-26T23:05:00}.

-@chapter Options
-@c man begin OPTIONS
-
-@include fftools-common-opts.texi
-
-@section Main options
-
-@table @option
-@item -f @var{configfile}
-Read configuration file @file{configfile}. If not specified it will
-read by default from @file{/etc/ffserver.conf}.
-
-@item -n
-Enable no-launch mode. This option disables all the @code{Launch}
-directives within the various @code{<Feed>} sections. Since
-@command{ffserver} will not launch any @command{ffmpeg} instances, you
-will have to launch them manually.
-
-@item -d
-Enable debug mode. This option increases log verbosity, and directs
-log messages to stdout. When specified, the @option{CustomLog} option
-is ignored.
-@end table
-
-@chapter Configuration file syntax
-
-@command{ffserver} reads a configuration file containing global
-options and settings for each stream and feed.
-
-The configuration file consists of global options and dedicated
-sections, which must be introduced by "<@var{SECTION_NAME}
-@var{ARGS}>" on a separate line and must be terminated by a line in
-the form "</@var{SECTION_NAME}>". @var{ARGS} is optional.
-
-Currently the following sections are recognized: @samp{Feed},
-@samp{Stream}, @samp{Redirect}.
-
-A line starting with @code{#} is ignored and treated as a comment.
-
-Name of options and sections are case-insensitive.
-
-@section ACL syntax
-An ACL (Access Control List) specifies the address which are allowed
-to access a given stream, or to write a given feed.
-
-It accepts the folling forms
-@itemize
-@item
-Allow/deny access to @var{address}.
-@example
-ACL ALLOW <address>
-ACL DENY <address>
-@end example
-
-@item
-Allow/deny access to ranges of addresses from @var{first_address} to
-@var{last_address}.
-@example
-ACL ALLOW <first_address> <last_address>
-ACL DENY <first_address> <last_address>
-@end example
-@end itemize
-
-You can repeat the ACL allow/deny as often as you like. It is on a per
-stream basis. The first match defines the action. If there are no matches,
-then the default is the inverse of the last ACL statement.
-
-Thus 'ACL allow localhost' only allows access from localhost.
-'ACL deny 1.0.0.0 1.255.255.255' would deny the whole of network 1 and
-allow everybody else.
-
-@section Global options
-@table @option
-@item Port @var{port_number}
-@item RTSPPort @var{port_number}
-
-Set TCP port number on which the HTTP/RTSP server is listening. You
-must select a different port from your standard HTTP web server if it
-is running on the same computer.
-
-If not specified, no corresponding server will be created.
-
-@item BindAddress @var{ip_address}
-@item RTSPBindAddress @var{ip_address}
-Set address on which the HTTP/RTSP server is bound. Only useful if you
-have several network interfaces.
-
-@item MaxHTTPConnections @var{n}
-Set number of simultaneous HTTP connections that can be handled. It
-has to be defined @emph{before} the @option{MaxClients} parameter,
-since it defines the @option{MaxClients} maximum limit.
-
-Default value is 2000.
-
-@item MaxClients @var{n}
-Set number of simultaneous requests that can be handled. Since
-@command{ffserver} is very fast, it is more likely that you will want
-to leave this high and use @option{MaxBandwidth}.
-
-Default value is 5.
-
-@item MaxBandwidth @var{kbps}
-Set the maximum amount of kbit/sec that you are prepared to consume
-when streaming to clients.
-
-Default value is 1000.
-
-@item CustomLog @var{filename}
-Set access log file (uses standard Apache log file format). '-' is the
-standard output.
-
-If not specified @command{ffserver} will produce no log.
-
-In case the commandline option @option{-d} is specified this option is
-ignored, and the log is written to standard output.
-
-@item NoDaemon
-Set no-daemon mode. This option is currently ignored since now
-@command{ffserver} will always work in no-daemon mode, and is
-deprecated.
-@end table
-
-@section Feed section
-
-A Feed section defines a feed provided to @command{ffserver}.
-
-Each live feed contains one video and/or audio sequence coming from an
-@command{ffmpeg} encoder or another @command{ffserver}. This sequence
-may be encoded simultaneously with several codecs at several
-resolutions.
-
-A feed instance specification is introduced by a line in the form:
-@example
-<Feed FEED_FILENAME>
-@end example
-
-where @var{FEED_FILENAME} specifies the unique name of the FFM stream.
-
-The following options are recognized within a Feed section.
-
-@table @option
-@item File @var{filename}
-@item ReadOnlyFile @var{filename}
-Set the path where the feed file is stored on disk.
-
-If not specified, the @file{/tmp/FEED.ffm} is assumed, where
-@var{FEED} is the feed name.
-
-If @option{ReadOnlyFile} is used the file is marked as read-only and
-it will not be deleted or updated.
-
-@item Truncate
-Truncate the feed file, rather than appending to it. By default
-@command{ffserver} will append data to the file, until the maximum
-file size value is reached (see @option{FileMaxSize} option).
-
-@item FileMaxSize @var{size}
-Set maximum size of the feed file in bytes. 0 means unlimited. The
-postfixes @code{K} (2^10), @code{M} (2^20), and @code{G} (2^30) are
-recognized.
-
-Default value is 5M.
-
-@item Launch @var{args}
-Launch an @command{ffmpeg} command when creating @command{ffserver}.
-
-@var{args} must be a sequence of arguments to be provided to an
-@command{ffmpeg} instance. The first provided argument is ignored, and
-it is replaced by a path with the same dirname of the @command{ffserver}
-instance, followed by the remaining argument and terminated with a
-path corresponding to the feed.
-
-When the launched process exits, @command{ffserver} will launch
-another program instance.
-
-In case you need a more complex @command{ffmpeg} configuration,
-e.g. if you need to generate multiple FFM feeds with a single
-@command{ffmpeg} instance, you should launch @command{ffmpeg} by hand.
-
-This option is ignored in case the commandline option @option{-n} is
-specified.
-
-@item ACL @var{spec}
-Specify the list of IP address which are allowed or denied to write
-the feed. Multiple ACL options can be specified.
-@end table
-
-@section Stream section
-
-A Stream section defines a stream provided by @command{ffserver}, and
-identified by a single name.
-
-The stream is sent when answering a request containing the stream
-name.
-
-A stream section must be introduced by the line:
-@example
-<Stream STREAM_NAME>
-@end example
-
-where @var{STREAM_NAME} specifies the unique name of the stream.
-
-The following options are recognized within a Stream section.
-
-Encoding options are marked with the @emph{encoding} tag, and they are
-used to set the encoding parameters, and are mapped to libavcodec
-encoding options. Not all encoding options are supported, in
-particular it is not possible to set encoder private options. In order
-to override the encoding options specified by @command{ffserver}, you
-can use the @command{ffmpeg} @option{override_ffserver} commandline
-option.
-
-Only one of the @option{Feed} and @option{File} options should be set.
-
-@table @option
-@item Feed @var{feed_name}
-Set the input feed. @var{feed_name} must correspond to an existing
-feed defined in a @code{Feed} section.
-
-When this option is set, encoding options are used to setup the
-encoding operated by the remote @command{ffmpeg} process.
-
-@item File @var{filename}
-Set the filename of the pre-recorded input file to stream.
-
-When this option is set, encoding options are ignored and the input
-file content is re-streamed as is.
-
-@item Format @var{format_name}
-Set the format of the output stream.
-
-Must be the name of a format recognized by FFmpeg. If set to
-@samp{status}, it is treated as a status stream.
-
-@item InputFormat @var{format_name}
-Set input format. If not specified, it is automatically guessed.
-
-@item Preroll @var{n}
-Set this to the number of seconds backwards in time to start. Note that
-most players will buffer 5-10 seconds of video, and also you need to allow
-for a keyframe to appear in the data stream.
-
-Default value is 0.
-
-@item StartSendOnKey
-Do not send stream until it gets the first key frame. By default
-@command{ffserver} will send data immediately.
-
-@item MaxTime @var{n}
-Set the number of seconds to run. This value set the maximum duration
-of the stream a client will be able to receive.
-
-A value of 0 means that no limit is set on the stream duration.

-All the numerical options, if not specified otherwise, accept a string
-representing a number as input, which may be followed by one of the SI
-unit prefixes, for example: 'K', 'M', or 'G'.
-
-If 'i' is appended to the SI unit prefix, the complete prefix will be
-interpreted as a unit prefix for binary multiplies, which are based on
-powers of 1024 instead of powers of 1000. Appending 'B' to the SI unit
-prefix multiplies the value by 8. This allows using, for example:
-'KB', 'MiB', 'G' and 'B' as number suffixes.
-
-Options which do not take arguments are boolean options, and set the
-corresponding value to true. They can be set to false by prefixing
-the option name with "no". For example using "-nofoo"
-will set the boolean option with name "foo" to false.
-
-@anchor{Stream specifiers}
-@section Stream specifiers
-Some options are applied per-stream, e.g. bitrate or codec. Stream specifiers
-are used to precisely specify which stream(s) a given option belongs to.
-
-A stream specifier is a string generally appended to the option name and
-separated from it by a colon. E.g. @code{-codec:a:1 ac3} contains the
-@code{a:1} stream specifier, which matches the second audio stream. Therefore, it
-would select the ac3 codec for the second audio stream.
-
-A stream specifier can match several streams, so that the option is applied to all
-of them. E.g. the stream specifier in @code{-b:a 128k} matches all audio
-streams.
-
-An empty stream specifier matches all streams. For example, @code{-codec copy}
-or @code{-codec: copy} would copy all the streams without reencoding.
-
-Possible forms of stream specifiers are:
-@table @option
-@item @var{stream_index}
-Matches the stream with this index. E.g. @code{-threads:1 4} would set the
-thread count for the second stream to 4.
-@item @var{stream_type}[:@var{stream_index}]
-@var{stream_type} is one of following: 'v' for video, 'a' for audio, 's' for subtitle,
-'d' for data, and 't' for attachments. If @var{stream_index} is given, then it matches
-stream number @var{stream_index} of this type. Otherwise, it matches all
-streams of this type.
-@item p:@var{program_id}[:@var{stream_index}]
-If @var{stream_index} is given, then it matches the stream with number @var{stream_index}
-in the program with the id @var{program_id}. Otherwise, it matches all streams in the
-program.
-@item #@var{stream_id}
-Matches the stream by a format-specific ID.

-Filter design
-=============
-
-This document explains guidelines that should be observed (or ignored with
-good reason) when writing filters for libavfilter.
-
-In this document, the word “frame” indicates either a video frame or a group
-of audio samples, as stored in an AVFilterBuffer structure.
-
-
-Format negotiation
-==================
-
-  The query_formats method should set, for each input and each output links,
-  the list of supported formats.
-
-  For video links, that means pixel format. For audio links, that means
-  channel layout, sample format (the sample packing is implied by the sample
-  format) and sample rate.
-
-  The lists are not just lists, they are references to shared objects. When
-  the negotiation mechanism computes the intersection of the formats
-  supported at each end of a link, all references to both lists are replaced
-  with a reference to the intersection. And when a single format is
-  eventually chosen for a link amongst the remaining list, again, all
-  references to the list are updated.
-
-  That means that if a filter requires that its input and output have the
-  same format amongst a supported list, all it has to do is use a reference
-  to the same list of formats.
-
-  query_formats can leave some formats unset and return AVERROR(EAGAIN) to
-  cause the negotiation mechanism to try again later. That can be used by
-  filters with complex requirements to use the format negotiated on one link
-  to set the formats supported on another.
-
-
-Buffer references ownership and permissions
-===========================================
-
-  Principle
-  ---------
-
-    Audio and video data are voluminous; the buffer and buffer reference
-    mechanism is intended to avoid, as much as possible, expensive copies of
-    that data while still allowing the filters to produce correct results.
-
-    The data is stored in buffers represented by AVFilterBuffer structures.
-    They must not be accessed directly, but through references stored in
-    AVFilterBufferRef structures. Several references can point to the
-    same buffer; the buffer is automatically deallocated once all
-    corresponding references have been destroyed.
-
-    The characteristics of the data (resolution, sample rate, etc.) are
-    stored in the reference; different references for the same buffer can
-    show different characteristics. In particular, a video reference can
-    point to only a part of a video buffer.
-
-    A reference is usually obtained as input to the start_frame or
-    filter_frame method or requested using the ff_get_video_buffer or
-    ff_get_audio_buffer functions. A new reference on an existing buffer can
-    be created with the avfilter_ref_buffer. A reference is destroyed using
-    the avfilter_unref_bufferp function.
-
-  Reference ownership
-  -------------------
-
-    At any time, a reference “belongs” to a particular piece of code,
-    usually a filter. With a few caveats that will be explained below, only
-    that piece of code is allowed to access it. It is also responsible for
-    destroying it, although this is sometimes done automatically (see the
-    section on link reference fields).
-
-    Here are the (fairly obvious) rules for reference ownership:
-
-    * A reference received by the filter_frame method (or its start_frame
-      deprecated version) belongs to the corresponding filter.
-
-      Special exception: for video references: the reference may be used
-      internally for automatic copying and must not be destroyed before
-      end_frame; it can be given away to ff_start_frame.
-
-    * A reference passed to ff_filter_frame (or the deprecated
-      ff_start_frame) is given away and must no longer be used.
-
-    * A reference created with avfilter_ref_buffer belongs to the code that
-      created it.
-
-    * A reference obtained with ff_get_video_buffer or ff_get_audio_buffer
-      belongs to the code that requested it.
-
-    * A reference given as return value by the get_video_buffer or
-      get_audio_buffer method is given away and must no longer be used.
-
-  Link reference fields
-  ---------------------
-
-    The AVFilterLink structure has a few AVFilterBufferRef fields. The
-    cur_buf and out_buf were used with the deprecated
-    start_frame/draw_slice/end_frame API and should no longer be used.
-    src_buf, cur_buf_copy and partial_buf are used by libavfilter internally
-    and must not be accessed by filters.
-
-  Reference permissions
-  ---------------------
-
-    The AVFilterBufferRef structure has a perms field that describes what
-    the code that owns the reference is allowed to do to the buffer data.
-    Different references for the same buffer can have different permissions.
-
-    For video filters that implement the deprecated
-    start_frame/draw_slice/end_frame API, the permissions only apply to the
-    parts of the buffer that have already been covered by the draw_slice
-    method.
-
-    The value is a binary OR of the following constants:
-
-    * AV_PERM_READ: the owner can read the buffer data; this is essentially
-      always true and is there for self-documentation.
-
-    * AV_PERM_WRITE: the owner can modify the buffer data.
-
-    * AV_PERM_PRESERVE: the owner can rely on the fact that the buffer data
-      will not be modified by previous filters.
-
-    * AV_PERM_REUSE: the owner can output the buffer several times, without
-      modifying the data in between.
-
-    * AV_PERM_REUSE2: the owner can output the buffer several times and
-      modify the data in between (useless without the WRITE permissions).
-
-    * AV_PERM_ALIGN: the owner can access the data using fast operations
-      that require data alignment.
-
-    The READ, WRITE and PRESERVE permissions are about sharing the same
-    buffer between several filters to avoid expensive copies without them
-    doing conflicting changes on the data.
-
-    The REUSE and REUSE2 permissions are about special memory for direct
-    rendering. For example a buffer directly allocated in video memory must
-    not modified once it is displayed on screen, or it will cause tearing;
-    it will therefore not have the REUSE2 permission.
-
-    The ALIGN permission is about extracting part of the buffer, for
-    copy-less padding or cropping for example.
-
-
-    References received on input pads are guaranteed to have all the
-    permissions stated in the min_perms field and none of the permissions
-    stated in the rej_perms.
-
-    References obtained by ff_get_video_buffer and ff_get_audio_buffer are
-    guaranteed to have at least all the permissions requested as argument.
-
-    References created by avfilter_ref_buffer have the same permissions as
-    the original reference minus the ones explicitly masked; the mask is
-    usually ~0 to keep the same permissions.
-
-    Filters should remove permissions on reference they give to output
-    whenever necessary. It can be automatically done by setting the
-    rej_perms field on the output pad.
-
-    Here are a few guidelines corresponding to common situations:
-
-    * Filters that modify and forward their frame (like drawtext) need the
-      WRITE permission.
-
-    * Filters that read their input to produce a new frame on output (like
-      scale) need the READ permission on input and must request a buffer
-      with the WRITE permission.
-
-    * Filters that intend to keep a reference after the filtering process
-      is finished (after filter_frame returns) must have the PRESERVE
-      permission on it and remove the WRITE permission if they create a new
-      reference to give it away.
-
-    * Filters that intend to modify a reference they have kept after the end
-      of the filtering process need the REUSE2 permission and must remove
-      the PRESERVE permission if they create a new reference to give it
-      away.
-
-
-Frame scheduling
-================
-
-  The purpose of these rules is to ensure that frames flow in the filter
-  graph without getting stuck and accumulating somewhere.
-
-  Simple filters that output one frame for each input frame should not have
-  to worry about it.
-
-  filter_frame
-  ------------
-
-    This method is called when a frame is pushed to the filter's input. It
-    can be called at any time except in a reentrant way.
-
-    If the input frame is enough to produce output, then the filter should
-    push the output frames on the output link immediately.
-
-    As an exception to the previous rule, if the input frame is enough to
-    produce several output frames, then the filter needs output only at
-    least one per link. The additional frames can be left buffered in the
-    filter; these buffered frames must be flushed immediately if a new input
-    produces new output.
-
-    (Example: frame rate-doubling filter: filter_frame must (1) flush the
-    second copy of the previous frame, if it is still there, (2) push the
-    first copy of the incoming frame, (3) keep the second copy for later.)
-
-    If the input frame is not enough to produce output, the filter must not
-    call request_frame to get more. It must just process the frame or queue
-    it. The task of requesting more frames is left to the filter's
-    request_frame method or the application.
-
-    If a filter has several inputs, the filter must be ready for frames
-    arriving randomly on any input. Therefore, any filter with several inputs
-    will most likely require some kind of queuing mechanism. It is perfectly
-    acceptable to have a limited queue and to drop frames when the inputs
-    are too unbalanced.
-
-  request_frame
-  -------------
-
-    This method is called when a frame is wanted on an output.
-
-    For an input, it should directly call filter_frame on the corresponding
-    output.
-
-    For a filter, if there are queued frames already ready, one of these
-    frames should be pushed. If not, the filter should request a frame on
-    one of its inputs, repeatedly until at least one frame has been pushed.
-
-    Return values:
-    if request_frame could produce a frame, it should return 0;
-    if it could not for temporary reasons, it should return AVERROR(EAGAIN);
-    if it could not because there are no more frames, it should return
-    AVERROR_EOF.
-
-    The typical implementation of request_frame for a filter with several
-    inputs will look like that:
-
-        if (frames_queued) {
-            push_one_frame();
-            return 0;
-        }
-        while (!frame_pushed) {
-            input = input_where_a_frame_is_most_needed();
-            ret = ff_request_frame(input);
-            if (ret == AVERROR_EOF) {
-                process_eof_on_input();
-            } else if (ret < 0) {
-                return ret;
-            }
-        }
-        return 0;
-
-    Note that, except for filters that can have queued frames, request_frame
-    does not push frames: it requests them to its input, and as a reaction,
-    the filter_frame method will be called and do the work.
-
-Legacy API
-==========
-
-  Until libavfilter 3.23, the filter_frame method was split:
-
-  - for video filters, it was made of start_frame, draw_slice (that could be
-    called several times on distinct parts of the frame) and end_frame;
-
-  - for audio filters, it was called filter_samples.

-can be set on all the muxers and demuxers. In addition each muxer or
-demuxer may support so-called private options, which are specific for
-that component.
-
-Options may be set by specifying -@var{option} @var{value} in the
-FFmpeg tools, or by setting the value explicitly in the
-@code{AVFormatContext} options or using the @file{libavutil/opt.h} API
-for programmatic use.
-
-The list of supported options follows:
-
-@table @option
-@item avioflags @var{flags} (@emph{input/output})
-Possible values:
-@table @samp
-@item direct
-Reduce buffering.
-@end table
-
-@item probesize @var{integer} (@emph{input})
-Set probing size in bytes, i.e. the size of the data to analyze to get
-stream information. A higher value will allow to detect more
-information in case it is dispersed into the stream, but will increase
-latency. Must be an integer not lesser than 32. It is 5000000 by default.
-
-@item packetsize @var{integer} (@emph{output})
-Set packet size.
-
-@item fflags @var{flags} (@emph{input/output})
-Set format flags.
-
-Possible values:
-@table @samp
-@item ignidx
-Ignore index.
-@item genpts
-Generate PTS.
-@item nofillin
-Do not fill in missing values that can be exactly calculated.
-@item noparse
-Disable AVParsers, this needs @code{+nofillin} too.
-@item igndts
-Ignore DTS.
-@item discardcorrupt
-Discard corrupted frames.
-@item sortdts
-Try to interleave output packets by DTS.
-@item keepside
-Do not merge side data.
-@item latm
-Enable RTP MP4A-LATM payload.
-@item nobuffer
-Reduce the latency introduced by optional buffering
-@end table
-
-@item seek2any @var{integer} (@emph{input})
-Allow seeking to non-keyframes on demuxer level when supported if set to 1.
-Default is 0.
-
-@item analyzeduration @var{integer} (@emph{input})
-Specify how many microseconds are analyzed to probe the input. A
-higher value will allow to detect more accurate information, but will
-increase latency. It defaults to 5,000,000 microseconds = 5 seconds.
-
-@item cryptokey @var{hexadecimal string} (@emph{input})
-Set decryption key.
-
-@item indexmem @var{integer} (@emph{input})
-Set max memory used for timestamp index (per stream).
-
-@item rtbufsize @var{integer} (@emph{input})
-Set max memory used for buffering real-time frames.
-
-@item fdebug @var{flags} (@emph{input/output})
-Print specific debug info.
-
-Possible values:
-@table @samp
-@item ts
-@end table
-
-@item max_delay @var{integer} (@emph{input/output})
-Set maximum muxing or demuxing delay in microseconds.
-
-@item fpsprobesize @var{integer} (@emph{input})
-Set number of frames used to probe fps.
-
-@item audio_preload @var{integer} (@emph{output})
-Set microseconds by which audio packets should be interleaved earlier.
-
-@item chunk_duration @var{integer} (@emph{output})
-Set microseconds for each chunk.
-
-@item chunk_size @var{integer} (@emph{output})
-Set size in bytes for each chunk.
-
-@item err_detect, f_err_detect @var{flags} (@emph{input})
-Set error detection flags. @code{f_err_detect} is deprecated and
-should be used only via the @command{ffmpeg} tool.
-
-Possible values:
-@table @samp
-@item crccheck
-Verify embedded CRCs.
-@item bitstream
-Detect bitstream specification deviations.
-@item buffer
-Detect improper bitstream length.
-@item explode
-Abort decoding on minor error detection.
-@item careful
-Consider things that violate the spec and have not been seen in the
-wild as errors.
-@item compliant
-Consider all spec non compliancies as errors.
-@item aggressive
-Consider things that a sane encoder should not do as an error.
-@end table
-
-@item use_wallclock_as_timestamps @var{integer} (@emph{input})
-Use wallclock as timestamps.
-
-@item avoid_negative_ts @var{integer} (@emph{output})
-
-Possible values:
-@table @samp
-@item make_non_negative
-Shift timestamps to make them non-negative.
-Also note that this affects only leading negative timestamps, and not
-non-monotonic negative timestamps.
-@item make_zero
-Shift timestamps so that the first timestamp is 0.
-@item auto (default)
-Enables shifting when required by the target format.
-@item disabled
-Disables shifting of timestamp.
-@end table
-
-When shifting is enabled, all output timestamps are shifted by the
-same amount. Audio, video, and subtitles desynching and relative
-timestamp differences are preserved compared to how they would have
-been without shifting.
-
-@item skip_initial_bytes @var{integer} (@emph{input})
-Set number of bytes to skip before reading header and frames if set to 1.
-Default is 0.
-
-@item correct_ts_overflow @var{integer} (@emph{input})
-Correct single timestamp overflows if set to 1. Default is 1.
-
-@item flush_packets @var{integer} (@emph{output})
-Flush the underlying I/O stream after each packet. Default 1 enables it, and
-has the effect of reducing the latency; 0 disables it and may slightly
-increase performance in some cases.
-
-@item output_ts_offset @var{offset} (@emph{output})
-Set the output time offset.
-
-@var{offset} must be a time duration specification,
-see @ref{time duration syntax,,the Time duration section in the ffmpeg-utils(1) manual,ffmpeg-utils}.
-
-The offset is added by the muxer to the output timestamps.
-
-Specifying a positive offset means that the corresponding streams are
-delayed bt the time duration specified in @var{offset}. Default value
-is @code{0} (meaning that no offset is applied).
-@end table
-
-@c man end FORMAT OPTIONS
-
-@anchor{Format stream specifiers}
-@section Format stream specifiers
-
-Format stream specifiers allow selection of one or more streams that
-match specific properties.
-
-Possible forms of stream specifiers are:
-@table @option
-@item @var{stream_index}
-Matches the stream with this index.
-
-@item @var{stream_type}[:@var{stream_index}]
-@var{stream_type} is one of following: 'v' for video, 'a' for audio,
-'s' for subtitle, 'd' for data, and 't' for attachments. If
-@var{stream_index} is given, then it matches the stream number
-@var{stream_index} of this type. Otherwise, it matches all streams of
-this type.
-
-@item p:@var{program_id}[:@var{stream_index}]
-If @var{stream_index} is given, then it matches the stream with number
-@var{stream_index} in the program with the id
-@var{program_id}. Otherwise, it matches all streams in the program.
-
-@item #@var{stream_id}
-Matches the stream by a format-specific ID.
-@end table
-
-The exact semantics of stream specifiers is defined by the
-@code{avformat_match_stream_specifier()} function declared in the
-@file{libavformat/avformat.h} header.

-@chapter Introduction
-
-This document aims in giving some quick references on a set of useful git
-commands. You should always use the extensive and detailed documentation
-provided directly by git:
-
-@example
-git --help
-man git
-@end example
-
-shows you the available subcommands,
-
-@example
-git <command> --help
-man git-<command>
-@end example
-
-shows information about the subcommand <command>.
-
-Additional information could be found on the
-@url{http://gitref.org, Git Reference} website
-
-For more information about the Git project, visit the
-
-@url{http://git-scm.com/, Git website}
-
-Consult these resources whenever you have problems, they are quite exhaustive.
-
-What follows now is a basic introduction to Git and some FFmpeg-specific
-guidelines to ease the contribution to the project
-
-@chapter Basics Usage
-
-@section Get GIT
-
-You can get git from @url{http://git-scm.com/}
-Most distribution and operating system provide a package for it.
-
-
-@section Cloning the source tree
-
-@example
-git clone git://source.ffmpeg.org/ffmpeg <target>
-@end example
-
-This will put the FFmpeg sources into the directory @var{<target>}.
-
-@example
-git clone git@@source.ffmpeg.org:ffmpeg <target>
-@end example
-
-This will put the FFmpeg sources into the directory @var{<target>} and let
-you push back your changes to the remote repository.
-
-Make sure that you do not have Windows line endings in your checkouts,
-otherwise you may experience spurious compilation failures. One way to
-achieve this is to run
-
-@example
-git config --global core.autocrlf false
-@end example
-
-
-@section Updating the source tree to the latest revision
-
-@example
-git pull (--rebase)
-@end example
-
-pulls in the latest changes from the tracked branch. The tracked branch
-can be remote. By default the master branch tracks the branch master in
-the remote origin.
-
-@float IMPORTANT
-@command{--rebase} (see below) is recommended.
-@end float
-
-@section Rebasing your local branches
-
-@example
-git pull --rebase
-@end example
-
-fetches the changes from the main repository and replays your local commits
-over it. This is required to keep all your local changes at the top of
-FFmpeg's master tree. The master tree will reject pushes with merge commits.
-
-
-@section Adding/removing files/directories
-
-@example
-git add [-A] <filename/dirname>
-git rm [-r] <filename/dirname>
-@end example
-
-GIT needs to get notified of all changes you make to your working
-directory that makes files appear or disappear.
-Line moves across files are automatically tracked.
-
-
-@section Showing modifications
-
-@example
-git diff <filename(s)>
-@end example
-
-will show all local modifications in your working directory as unified diff.
-
-
-@section Inspecting the changelog
-
-@example
-git log <filename(s)>
-@end example
-
-You may also use the graphical tools like gitview or gitk or the web
-interface available at http://source.ffmpeg.org/
-
-@section Checking source tree status
-
-@example
-git status
-@end example
-
-detects all the changes you made and lists what actions will be taken in case
-of a commit (additions, modifications, deletions, etc.).
-
-
-@section Committing
-
-@example
-git diff --check
-@end example
-
-to double check your changes before committing them to avoid trouble later
-on. All experienced developers do this on each and every commit, no matter
-how small.
-Every one of them has been saved from looking like a fool by this many times.
-It's very easy for stray debug output or cosmetic modifications to slip in,
-please avoid problems through this extra level of scrutiny.
-
-For cosmetics-only commits you should get (almost) empty output from
-
-@example
-git diff -w -b <filename(s)>
-@end example
-
-Also check the output of
-
-@example
-git status
-@end example
-
-to make sure you don't have untracked files or deletions.
-
-@example
-git add [-i|-p|-A] <filenames/dirnames>
-@end example
-
-Make sure you have told git your name and email address
-
-@example
-git config --global user.name "My Name"
-git config --global user.email my@@email.invalid
-@end example
-
-Use @var{--global} to set the global configuration for all your git checkouts.
-
-Git will select the changes to the files for commit. Optionally you can use
-the interactive or the patch mode to select hunk by hunk what should be
-added to the commit.
-
-
-@example
-git commit
-@end example
-
-Git will commit the selected changes to your current local branch.
-
-You will be prompted for a log message in an editor, which is either
-set in your personal configuration file through
-
-@example
-git config --global core.editor
-@end example
-
-or set by one of the following environment variables:
-@var{GIT_EDITOR}, @var{VISUAL} or @var{EDITOR}.
-
-Log messages should be concise but descriptive. Explain why you made a change,
-what you did will be obvious from the changes themselves most of the time.
-Saying just "bug fix" or "10l" is bad. Remember that people of varying skill
-levels look at and educate themselves while reading through your code. Don't
-include filenames in log messages, Git provides that information.
-
-Possibly make the commit message have a terse, descriptive first line, an
-empty line and then a full description. The first line will be used to name
-the patch by git format-patch.
-
-@section Preparing a patchset
-
-@example
-git format-patch <commit> [-o directory]
-@end example
-
-will generate a set of patches for each commit between @var{<commit>} and
-current @var{HEAD}. E.g.
-
-@example
-git format-patch origin/master
-@end example
-
-will generate patches for all commits on current branch which are not
-present in upstream.
-A useful shortcut is also
-
-@example
-git format-patch -n
-@end example
-
-which will generate patches from last @var{n} commits.
-By default the patches are created in the current directory.
-
-@section Sending patches for review
-
-@example
-git send-email <commit list|directory>
-@end example
-
-will send the patches created by @command{git format-patch} or directly
-generates them. All the email fields can be configured in the global/local
-configuration or overridden by command line.
-Note that this tool must often be installed separately (e.g. @var{git-email}
-package on Debian-based distros).
-
-
-@section Renaming/moving/copying files or contents of files
-
-Git automatically tracks such changes, making those normal commits.
-
-@example
-mv/cp path/file otherpath/otherfile
-git add [-A] .
-git commit
-@end example
-
-
-@chapter Git configuration
-
-In order to simplify a few workflows, it is advisable to configure both
-your personal Git installation and your local FFmpeg repository.
-
-@section Personal Git installation
-
-Add the following to your @file{~/.gitconfig} to help @command{git send-email}
-and @command{git format-patch} detect renames:
-
-@example
-[diff]
-        renames = copy
-@end example
-
-@section Repository configuration
-
-In order to have @command{git send-email} automatically send patches
-to the ffmpeg-devel mailing list, add the following stanza
-to @file{/path/to/ffmpeg/repository/.git/config}:
-
-@example
-[sendemail]
-        to = ffmpeg-devel@@ffmpeg.org
-@end example
-
-@chapter FFmpeg specific
-
-@section Reverting broken commits
-
-@example
-git reset <commit>
-@end example
-
-@command{git reset} will uncommit the changes till @var{<commit>} rewriting
-the current branch history.
-
-@example
-git commit --amend
-@end example
-
-allows one to amend the last commit details quickly.
-
-@example
-git rebase -i origin/master
-@end example
-
-will replay local commits over the main repository allowing to edit, merge
-or remove some of them in the process.
-
-@float NOTE
-@command{git reset}, @command{git commit --amend} and @command{git rebase}
-rewrite history, so you should use them ONLY on your local or topic branches.
-The main repository will reject those changes.
-@end float
-
-@example
-git revert <commit>
-@end example
-
-@command{git revert} will generate a revert commit. This will not make the
-faulty commit disappear from the history.
-
-@section Pushing changes to remote trees
-
-@example
-git push
-@end example
-
-Will push the changes to the default remote (@var{origin}).
-Git will prevent you from pushing changes if the local and remote trees are
-out of sync. Refer to and to sync the local tree.
-
-@example
-git remote add <name> <url>
-@end example
-
-Will add additional remote with a name reference, it is useful if you want
-to push your local branch for review on a remote host.
-
-@example
-git push <remote> <refspec>
-@end example
-
-Will push the changes to the @var{<remote>} repository.
-Omitting @var{<refspec>} makes @command{git push} update all the remote
-branches matching the local ones.
-
-@section Finding a specific svn revision
-
-Since version 1.7.1 git supports @var{:/foo} syntax for specifying commits
-based on a regular expression. see man gitrevisions
-
-@example
-git show :/'as revision 23456'
-@end example
-
-will show the svn changeset @var{r23456}. With older git versions searching in
-the @command{git log} output is the easiest option (especially if a pager with
-search capabilities is used).
-This commit can be checked out with
-
-@example
-git checkout -b svn_23456 :/'as revision 23456'
-@end example
-
-or for git < 1.7.1 with
-
-@example
-git checkout -b svn_23456 $SHA1
-@end example
-
-where @var{$SHA1} is the commit hash from the @command{git log} output.
-
-
-@chapter pre-push checklist
-
-Once you have a set of commits that you feel are ready for pushing,
-work through the following checklist to doublecheck everything is in
-proper order. This list tries to be exhaustive. In case you are just
-pushing a typo in a comment, some of the steps may be unnecessary.
-Apply your common sense, but if in doubt, err on the side of caution.
-
-First, make sure that the commits and branches you are going to push
-match what you want pushed and that nothing is missing, extraneous or
-wrong. You can see what will be pushed by running the git push command
-with --dry-run first. And then inspecting the commits listed with
-@command{git log -p 1234567..987654}. The @command{git status} command
-may help in finding local changes that have been forgotten to be added.
-
-Next let the code pass through a full run of our testsuite.
-
-@itemize
-@item @command{make distclean}
-@item @command{/path/to/ffmpeg/configure}
-@item @command{make check}
-@item if fate fails due to missing samples run @command{make fate-rsync} and retry
-@end itemize
-
-Make sure all your changes have been checked before pushing them, the
-testsuite only checks against regressions and that only to some extend. It does
-obviously not check newly added features/code to be working unless you have
-added a test for that (which is recommended).
-
-Also note that every single commit should pass the test suite, not just
-the result of a series of patches.
-
-Once everything passed, push the changes to your public ffmpeg clone and post a
-merge request to ffmpeg-devel. You can also push them directly but this is not
-recommended.
-
-@chapter Server Issues
-
-Contact the project admins @email{root@@ffmpeg.org} if you have technical
-problems with the GIT server.

+@settitle Video Hook Documentation
+@titlepage
+@sp 7
+@center @titlefont{Video Hook Documentation}
+@sp 3
+@end titlepage
+
+
+@chapter Introduction
+
+@var{Please be aware that vhook is deprecated, and hence its development is
+frozen (bug fixes are still accepted).
+The substitute will be 'libavfilter', the result of our 'Video Filter API'
+Google Summer of Code project. You may monitor its progress by subscribing to
+the ffmpeg-soc mailing list at
+@url{http://lists.mplayerhq.hu/mailman/listinfo/ffmpeg-soc}.}
+
+The video hook functionality is designed (mostly) for live video. It allows
+the video to be modified or examined between the decoder and the encoder.
+
+Any number of hook modules can be placed inline, and they are run in the
+order that they were specified on the ffmpeg command line.
+
+The video hook modules are provided for use as a base for your own modules,
+and are described below.
+
+Modules are loaded using the -vhook option to ffmpeg. The value of this parameter
+is a space separated list of arguments. The first is the module name, and the rest
+are passed as arguments to the Configure function of the module.
+
+The modules are dynamic libraries: They have different suffixes (.so, .dll, .dylib)
+depending on your platform. And your platform dictates if they need to be
+somewhere in your PATH, or in your LD_LIBRARY_PATH. Otherwise you will need to
+specify the full path of the vhook file that you are using.
+
+@section null.c
+
+This does nothing. Actually it converts the input image to RGB24 and then converts
+it back again. This is meant as a sample that you can use to test your setup.
+
+@section fish.c
+
+This implements a 'fish detector'. Essentially it converts the image into HSV
+space and tests whether more than a certain percentage of the pixels fall into
+a specific HSV cuboid. If so, then the image is saved into a file for processing
+by other bits of code.
+
+Why use HSV? It turns out that HSV cuboids represent a more compact range of
+colors than would an RGB cuboid.
+
+@section imlib2.c
+
+This module implements a text overlay for a video image. Currently it
+supports a fixed overlay or reading the text from a file. The string
+is passed through strftime() so that it is easy to imprint the date and
+time onto the image.
+
+This module depends on the external library imlib2, available on
+Sourceforge, among other places, if it is not already installed on
+your system.
+
+You may also overlay an image (even semi-transparent) like TV stations do.
+You may move either the text or the image around your video to create
+scrolling credits, for example.
+
+The font file used is looked for in a FONTPATH environment variable, and
+prepended to the point size as a command line option and can be specified
+with the full path to the font file, as in:
+@example
+-F /usr/X11R6/lib/X11/fonts/TTF/VeraBd.ttf/20
+@end example
+where 20 is the point size.
+
+You can specify the filename to read RGB color names from. If it is not
+specified, these defaults are used: @file{/usr/share/X11/rgb.txt} and
+@file{/usr/lib/X11/rgb.txt}
+
+Options:
+@multitable @columnfractions .2 .8
+@item @option{-C <rgb.txt>}   @tab The filename to read RGB color names from
+@item @option{-c <color>}     @tab The color of the text
+@item @option{-F <fontname>}  @tab The font face and size
+@item @option{-t <text>}      @tab The text
+@item @option{-f <filename>}  @tab The filename to read text from
+@item @option{-x <expression>}@tab x coordinate of text or image
+@item @option{-y <expression>}@tab y coordinate of text or image
+@item @option{-i <filename>}  @tab The filename to read a image from
+@item @option{-R <expression>}@tab Value for R color
+@item @option{-G <expression>}@tab Value for G color
+@item @option{-B <expression>}@tab Value for B color
+@item @option{-A <expression>}@tab Value for Alpha channel
+@end multitable
+
+Expressions are functions of these variables:
+@multitable @columnfractions .2 .8
+@item @var{N} @tab frame number (starting at zero)
+@item @var{H} @tab frame height
+@item @var{W} @tab frame width
+@item @var{h} @tab image height
+@item @var{w} @tab image width
+@item @var{X} @tab previous x coordinate of text or image
+@item @var{Y} @tab previous y coordinate of text or image
+@end multitable
+
+You may also use the constants @var{PI}, @var{E}, and the math functions available at the
+FFmpeg formula evaluator at (@url{ffmpeg-doc.html#SEC13}), except @var{bits2qp(bits)}
+and @var{qp2bits(qp)}.
+
+Usage examples:
+
+@example
+   # Remember to set the path to your fonts
+   FONTPATH="/cygdrive/c/WINDOWS/Fonts/"
+   FONTPATH="$FONTPATH:/usr/share/imlib2/data/fonts/"
+   FONTPATH="$FONTPATH:/usr/X11R6/lib/X11/fonts/TTF/"
+   export FONTPATH
+
+   # Bulb dancing in a Lissajous pattern
+   ffmpeg -i input.avi -vhook \
+     'vhook/imlib2.dll -x W*(0.5+0.25*sin(N/47*PI))-w/2 -y H*(0.5+0.50*cos(N/97*PI))-h/2 -i /usr/share/imlib2/data/images/bulb.png' \
+     -acodec copy -sameq output.avi
+
+   # Text scrolling
+   ffmpeg -i input.avi -vhook \
+     'vhook/imlib2.dll -c red -F Vera.ttf/20 -x 150+0.5*N -y 70+0.25*N -t Hello' \
+     -acodec copy -sameq output.avi
+
+   # Date and time stamp, security-camera style:
+   ffmpeg -r 29.97 -s 320x256 -f video4linux -i /dev/video0 \
+     -vhook 'vhook/imlib2.so -x 0 -y 0 -i black-260x20.png' \
+     -vhook 'vhook/imlib2.so -c white -F VeraBd.ttf/12 -x 0 -y 0 -t %A-%D-%T' \
+     output.avi
+
+     In this example the video is captured from the first video capture card as a
+     320x256 AVI, and a black 260 by 20 pixel PNG image is placed in the upper
+     left corner, with the day, date and time overlaid on it in Vera Bold 12
+     point font. A simple black PNG file 260 pixels wide and 20 pixels tall
+     was created in the GIMP for this purpose.
+
+   # Scrolling credits from a text file
+   ffmpeg -i input.avi -vhook \

+     In this example, the text is stored in a file, and is positioned 100
+     pixels from the left hand edge of the video. The text is scrolled from the
+     bottom up. Making the y factor positive will scroll from the top down.
+     Increasing the magnitude of the y factor makes the text scroll faster,
+     decreasing it makes it scroll slower. Hint: Blank lines containing only
+     a newline are treated as end-of-file. To create blank lines, use lines
+     that consist of space characters only.
+
+   # Scrolling credits with custom color from a text file
+   ffmpeg -i input.avi -vhook \
+     'vhook/imlib2.so -C rgb.txt -c CustomColor1 -F VeraBd.ttf/16 -x 100 -y -1.0*N -f credits.txt' \
+     -sameq output.avi
+
+     This example does the same as the one above, but specifies an rgb.txt file
+     to be used, which has a custom-made color in it.
+
+   # Variable colors
+   ffmpeg -i input.avi -vhook \
+     'vhook/imlib2.so -t Hello -R abs(255*sin(N/47*PI)) -G abs(255*sin(N/47*PI)) -B abs(255*sin(N/47*PI))' \
+     -sameq output.avi
+
+     In this example, the color for the text goes up and down from black to
+     white.
+
+   # Text fade-out
+   ffmpeg -i input.avi -vhook \
+     'vhook/imlib2.so -t Hello -A max(0,255-exp(N/47))' \
+     -sameq output.avi
+
+     In this example, the text fades out in about 10 seconds for a 25 fps input
+     video file.
+
+   # scrolling credits from a graphics file
+   ffmpeg -sameq -i input.avi \
+     -vhook 'vhook/imlib2.so -x 0 -y -1.0*N -i credits.png' output.avi
+
+     In this example, a transparent PNG file the same width as the video
+     (e.g. 320 pixels), but very long, (e.g. 3000 pixels), was created, and
+     text, graphics, brushstrokes, etc, were added to the image. The image
+     is then scrolled up, from the bottom of the frame.
+
+@end example
+
+@section ppm.c
+
+It's basically a launch point for a PPM pipe, so you can use any
+executable (or script) which consumes a PPM on stdin and produces a PPM
+on stdout (and flushes each frame). The Netpbm utilities are a series of
+such programs.
+
+A list of them is here:
+
+@url{http://netpbm.sourceforge.net/doc/directory.html}
+
+Usage example:
+
+@example
+ffmpeg -i input -vhook "/path/to/ppm.so some-ppm-filter args" output
+@end example
+
+@section drawtext.c
+
+This module implements a text overlay for a video image. Currently it
+supports a fixed overlay or reading the text from a file. The string
+is passed through strftime() so that it is easy to imprint the date and
+time onto the image.
+
+Features:
+@itemize @minus
+@item TrueType, Type1 and others via the FreeType2 library
+@item Font kerning (better output)
+@item Line Wrap (put the text that doesn't fit one line on the next line)
+@item Background box (currently in development)
+@item Outline
+@end itemize
+
+Options:
+@multitable @columnfractions .2 .8
+@item @option{-c <color>}          @tab Foreground color of the text ('internet' way) <#RRGGBB> [default #FFFFFF]
+@item @option{-C <color>}          @tab Background color of the text ('internet' way) <#RRGGBB> [default #000000]
+@item @option{-f <font-filename>}  @tab font file to use
+@item @option{-t <text>}           @tab text to display
+@item @option{-T <filename>}       @tab file to read text from
+@item @option{-x <pos>}            @tab x coordinate of the start of the text
+@item @option{-y <pos>}            @tab y coordinate of the start of the text
+@end multitable
+
+Text fonts are being looked for in a FONTPATH environment variable.
+If the FONTPATH environment variable is not available, or is not checked by
+your target (i.e. Cygwin), then specify the full path to the font file as in:
+@example
+-f /usr/X11R6/lib/X11/fonts/TTF/VeraBd.ttf
+@end example
+
+Usage Example:
+@example
+   # Remember to set the path to your fonts
+   FONTPATH="/cygdrive/c/WINDOWS/Fonts/"
+   FONTPATH="$FONTPATH:/usr/share/imlib2/data/fonts/"
+   FONTPATH="$FONTPATH:/usr/X11R6/lib/X11/fonts/TTF/"
+   export FONTPATH
+
+   # Time and date display
+   ffmpeg -f video4linux2 -i /dev/video0 \
+   -vhook 'vhook/drawtext.so -f VeraBd.ttf -t %A-%D-%T' movie.mpg
+
+     This example grabs video from the first capture card and outputs it to an
+     MPEG video, and places "Weekday-dd/mm/yy-hh:mm:ss" at the top left of the
+     frame, updated every second, using the Vera Bold TrueType Font, which
+     should exist in: /usr/X11R6/lib/X11/fonts/TTF/
+@end example
+
+Check the man page for strftime() for all the various ways you can format
+the date and time.
+
+@section watermark.c
+
+Command Line options:
+@multitable @columnfractions .2 .8
+@item @option{-m [0|1]}            @tab Mode (default: 0, see below)
+@item @option{-t 000000 - FFFFFF}  @tab Threshold, six digit hex number
+@item @option{-f <filename>}       @tab Watermark image filename, must be specified!
+@end multitable
+
+MODE 0:
+ The watermark picture works like this (assuming color intensities 0..0xFF):
+ Per color do this:
+ If mask color is 0x80, no change to the original frame.
+ If mask color is < 0x80 the absolute difference is subtracted from the
+ frame. If result < 0, result = 0.
+ If mask color is > 0x80 the absolute difference is added to the
+ frame. If result > 0xFF, result = 0xFF.
+
+ You can override the 0x80 level with the -t flag. E.g. if threshold is
+ 000000 the color value of watermark is added to the destination.
+
+ This way a mask that is visible both in light and dark pictures can be made
+ (e.g. by using a picture generated by the Gimp and the bump map tool).
+
+ An example watermark file is at:
+ @url{http://engene.se/ffmpeg_watermark.gif}
+
+MODE 1:
+ Per color do this:
+ If mask color > threshold color then the watermark pixel is used.
+
+Example usage:
+@example
+   ffmpeg -i infile -vhook '/path/watermark.so -f wm.gif' -an out.mov
+   ffmpeg -i infile -vhook '/path/watermark.so -f wm.gif -m 1 -t 222222' -an out.mov

-@chapter Input Devices
-@c man begin INPUT DEVICES
-
-Input devices are configured elements in FFmpeg which allow to access
-the data coming from a multimedia device attached to your system.
-
-When you configure your FFmpeg build, all the supported input devices
-are enabled by default. You can list all available ones using the
-configure option "--list-indevs".
-
-You can disable all the input devices using the configure option
-"--disable-indevs", and selectively enable an input device using the
-option "--enable-indev=@var{INDEV}", or you can disable a particular
-input device using the option "--disable-indev=@var{INDEV}".
-
-The option "-formats" of the ff* tools will display the list of
-supported input devices (amongst the demuxers).
-
-A description of the currently available input devices follows.
-
-@section alsa
-
-ALSA (Advanced Linux Sound Architecture) input device.
-
-To enable this input device during configuration you need libasound
-installed on your system.
-
-This device allows capturing from an ALSA device. The name of the
-device to capture has to be an ALSA card identifier.
-
-An ALSA identifier has the syntax:
-@example
-hw:@var{CARD}[,@var{DEV}[,@var{SUBDEV}]]
-@end example
-
-where the @var{DEV} and @var{SUBDEV} components are optional.
-
-The three arguments (in order: @var{CARD},@var{DEV},@var{SUBDEV})
-specify card number or identifier, device number and subdevice number
-(-1 means any).
-
-To see the list of cards currently recognized by your system check the
-files @file{/proc/asound/cards} and @file{/proc/asound/devices}.
-
-For example to capture with @command{ffmpeg} from an ALSA device with
-card id 0, you may run the command:
-@example
-ffmpeg -f alsa -i hw:0 alsaout.wav
-@end example
-
-For more information see:
-@url{http://www.alsa-project.org/alsa-doc/alsa-lib/pcm.html}
-
-@section bktr
-
-BSD video input device.
-
-@section dshow
-
-Windows DirectShow input device.
-
-DirectShow support is enabled when FFmpeg is built with the mingw-w64 project.
-Currently only audio and video devices are supported.
-
-Multiple devices may be opened as separate inputs, but they may also be
-opened on the same input, which should improve synchronism between them.
-
-The input name should be in the format:
-
-@example
-@var{TYPE}=@var{NAME}[:@var{TYPE}=@var{NAME}]
-@end example
-
-where @var{TYPE} can be either @var{audio} or @var{video},
-and @var{NAME} is the device's name.
-
-@subsection Options
-
-If no options are specified, the device's defaults are used.
-If the device does not support the requested options, it will
-fail to open.
-
-@table @option

-Set video device number for devices with same name (starts at 0,
-defaults to 0).
-
-@item audio_device_number
-Set audio device number for devices with same name (starts at 0,
-defaults to 0).
-
-@item pixel_format
-Select pixel format to be used by DirectShow. This may only be set when
-the video codec is not set or set to rawvideo.
-
-@item audio_buffer_size
-Set audio device buffer size in milliseconds (which can directly
-impact latency, depending on the device).
-Defaults to using the audio device's
-default buffer size (typically some multiple of 500ms).
-Setting this value too low can degrade performance.

-@section dv1394
-
-Linux DV 1394 input device.
-
-@section fbdev
-
-Linux framebuffer input device.
-
-The Linux framebuffer is a graphic hardware-independent abstraction
-layer to show graphics on a computer monitor, typically on the
-console. It is accessed through a file device node, usually
-@file{/dev/fb0}.
-
-For more detailed information read the file
-Documentation/fb/framebuffer.txt included in the Linux source tree.
-
-To record from the framebuffer device @file{/dev/fb0} with
-@command{ffmpeg}:
-@example
-ffmpeg -f fbdev -r 10 -i /dev/fb0 out.avi
-@end example
-
-You can take a single screenshot image with the command:
-@example
-ffmpeg -f fbdev -frames:v 1 -r 1 -i /dev/fb0 screenshot.jpeg
-@end example
-
-See also @url{http://linux-fbdev.sourceforge.net/}, and fbset(1).
-
-@section iec61883
-
-FireWire DV/HDV input device using libiec61883.
-
-To enable this input device, you need libiec61883, libraw1394 and
-libavc1394 installed on your system. Use the configure option
-@code{--enable-libiec61883} to compile with the device enabled.
-
-The iec61883 capture device supports capturing from a video device
-connected via IEEE1394 (FireWire), using libiec61883 and the new Linux
-FireWire stack (juju). This is the default DV/HDV input method in Linux
-Kernel 2.6.37 and later, since the old FireWire stack was removed.
-
-Specify the FireWire port to be used as input file, or "auto"
-to choose the first port connected.
-
-@subsection Options
-
-@table @option
-
-@item dvtype
-Override autodetection of DV/HDV. This should only be used if auto
-detection does not work, or if usage of a different device type
-should be prohibited. Treating a DV device as HDV (or vice versa) will
-not work and result in undefined behavior.
-The values @option{auto}, @option{dv} and @option{hdv} are supported.
-
-@item dvbuffer
-Set maxiumum size of buffer for incoming data, in frames. For DV, this
-is an exact value. For HDV, it is not frame exact, since HDV does
-not have a fixed frame size.
-
-@item dvguid
-Select the capture device by specifying it's GUID. Capturing will only
-be performed from the specified device and fails if no device with the
-given GUID is found. This is useful to select the input if multiple
-devices are connected at the same time.
-Look at /sys/bus/firewire/devices to find out the GUIDs.
-
-@end table
-
-@subsection Examples
-
-@itemize

-
-@section jack
-
-JACK input device.
-
-To enable this input device during configuration you need libjack
-installed on your system.
-
-A JACK input device creates one or more JACK writable clients, one for
-each audio channel, with name @var{client_name}:input_@var{N}, where
-@var{client_name} is the name provided by the application, and @var{N}
-is a number which identifies the channel.
-Each writable client will send the acquired data to the FFmpeg input
-device.
-
-Once you have created one or more JACK readable clients, you need to
-connect them to one or more JACK writable clients.
-
-To connect or disconnect JACK clients you can use the @command{jack_connect}
-and @command{jack_disconnect} programs, or do it through a graphical interface,
-for example with @command{qjackctl}.
-
-To list the JACK clients and their properties you can invoke the command
-@command{jack_lsp}.
-
-Follows an example which shows how to capture a JACK readable client
-with @command{ffmpeg}.
-@example
-# Create a JACK writable client with name "ffmpeg".
-$ ffmpeg -f jack -i ffmpeg -y out.wav
-
-# Start the sample jack_metro readable client.
-$ jack_metro -b 120 -d 0.2 -f 4000
-
-# List the current JACK clients.
-$ jack_lsp -c
-system:capture_1
-system:capture_2
-system:playback_1
-system:playback_2
-ffmpeg:input_1
-metro:120_bpm

-# Connect metro to the ffmpeg writable client.
-$ jack_connect metro:120_bpm ffmpeg:input_1
-@end example
-
-For more information read:
-@url{http://jackaudio.org/}
-
-@section lavfi
-
-Libavfilter input virtual device.
-
-This input device reads data from the open output pads of a libavfilter
-filtergraph.
-
-For each filtergraph open output, the input device will create a
-corresponding stream which is mapped to the generated output. Currently
-only video data is supported. The filtergraph is specified through the
-option @option{graph}.
-
-@subsection Options
-
-@table @option
-
-@item graph
-Specify the filtergraph to use as input. Each video open output must be
-labelled by a unique string of the form "out@var{N}", where @var{N} is a
-number starting from 0 corresponding to the mapped input stream
-generated by the device.
-The first unlabelled output is automatically assigned to the "out0"
-label, but all the others need to be specified explicitly.
-
-If not specified defaults to the filename specified for the input
-device.
-
-@item graph_file
-Set the filename of the filtergraph to be read and sent to the other
-filters. Syntax of the filtergraph is the same as the one specified by
-the option @var{graph}.
-
-@end table
-
-@subsection Examples
-
-@itemize
-@item
-Create a color video stream and play it back with @command{ffplay}:
-@example
-ffplay -f lavfi -graph "color=c=pink [out0]" dummy

-
-@item
-As the previous example, but use filename for specifying the graph
-description, and omit the "out0" label:
-@example
-ffplay -f lavfi color=c=pink
-@end example
-
-@item
-Create three different video test filtered sources and play them:
-@example
-ffplay -f lavfi -graph "testsrc [out0]; testsrc,hflip [out1]; testsrc,negate [out2]" test3
-@end example
-
-@item
-Read an audio stream from a file using the amovie source and play it

-
-The OpenAL input device provides audio capture on all systems with a
-working OpenAL 1.1 implementation.
-
-To enable this input device during configuration, you need OpenAL
-headers and libraries installed on your system, and need to configure
-FFmpeg with @code{--enable-openal}.
-
-OpenAL headers and libraries should be provided as part of your OpenAL
-implementation, or as an additional download (an SDK). Depending on your
-installation you may need to specify additional flags via the
-@code{--extra-cflags} and @code{--extra-ldflags} for allowing the build
-system to locate the OpenAL headers and libraries.

-@end example
-
-Capture from two devices simultaneously, writing to two different files,
-within the same @command{ffmpeg} command:
-@example
-$ ffmpeg -f openal -i 'DR-BT101 via PulseAudio' out1.ogg -f openal -i 'ALSA Default' out2.ogg
-@end example
-Note: not all OpenAL implementations support multiple simultaneous capture -
-try the latest OpenAL Soft if the above does not work.
-
-@section oss
-
-Open Sound System input device.
-
-The filename to provide to the input device is the device node
-representing the OSS input device, and is usually set to
-@file{/dev/dsp}.

-@end example
-
-@section video4linux2, v4l2
-
-Video4Linux2 input video device.
-
-"v4l2" can be used as alias for "video4linux2".
-
-If FFmpeg is built with v4l-utils support (by using the
-@code{--enable-libv4l2} configure option), it is possible to use it with the
-@code{-use_libv4l2} input device option.
-
-The name of the device to grab is a file device node, usually Linux
-systems tend to automatically create such nodes when the device
-(e.g. an USB webcam) is plugged into the system, and has a name of the
-kind @file{/dev/video@var{N}}, where @var{N} is a number associated to
-the device.
-
-Video4Linux2 devices usually support a limited set of
-@var{width}x@var{height} sizes and frame rates. You can check which are
-supported using @command{-list_formats all} for Video4Linux2 devices.
-Some devices, like TV cards, support one or more standards. It is possible
-to list all the supported standards using @command{-list_standards all}.
-
-The time base for the timestamps is 1 microsecond. Depending on the kernel
-version and configuration, the timestamps may be derived from the real time
-clock (origin at the Unix Epoch) or the monotonic clock (origin usually at
-boot time, unaffected by NTP or manual changes to the clock). The
-@option{-timestamps abs} or @option{-ts abs} option can be used to force
-conversion into the real time clock.
-
-Some usage examples of the video4linux2 device with @command{ffmpeg}
-and @command{ffplay}:
-@itemize
-@item
-Grab and show the input of a video4linux2 device:
-@example
-ffplay -f video4linux2 -framerate 30 -video_size hd720 /dev/video0
-@end example
-
-@item
-Grab and record the input of a video4linux2 device, leave the
-frame rate and size as previously set:
-@example
-ffmpeg -f video4linux2 -input_format mjpeg -i /dev/video0 out.mpeg
-@end example
-@end itemize
-
-For more information about Video4Linux, check @url{http://linuxtv.org/}.
-
-@subsection Options
-
-@table @option
-@item standard
-Set the standard. Must be the name of a supported standard. To get a
-list of the supported standards, use the @option{list_standards}
-option.
-
-@item channel
-Set the input channel number. Default to -1, which means using the
-previously selected channel.
-
-@item video_size
-Set the video frame size. The argument must be a string in the form
-@var{WIDTH}x@var{HEIGHT} or a valid size abbreviation.
-
-@item pixel_format
-Select the pixel format (only valid for raw video input).
-
-@item input_format
-Set the preferred pixel format (for raw video) or a codec name.
-This option allows one to select the input format, when several are
-available.
-
-@item framerate
-Set the preferred video frame rate.
-
-@item list_formats
-List available formats (supported pixel formats, codecs, and frame
-sizes) and exit.
-
-Available values are:
-@table @samp
-@item all
-Show all available (compressed and non-compressed) formats.
-
-@item raw
-Show only raw video (non-compressed) formats.
-
-@item compressed
-Show only compressed formats.
-@end table
-
-@item list_standards
-List supported standards and exit.
-
-Available values are:
-@table @samp
-@item all
-Show all supported standards.
-@end table
-
-@item timestamps, ts
-Set type of timestamps for grabbed frames.
-
-Available values are:
-@table @samp
-@item default
-Use timestamps from the kernel.
-
-@item abs
-Use absolute timestamps (wall clock).
-
-@item mono2abs
-Force conversion from monotonic to absolute timestamps.
-@end table
-
-Default value is @code{default}.
-@end table
-
-@section vfwcap
-
-VfW (Video for Windows) capture input device.
-
-The filename passed as input is the capture driver number, ranging from
-0 to 9. You may use "list" as filename to print a list of drivers. Any
-other filename will be interpreted as device number 0.
-
-@section x11grab
-
-X11 video input device.
-
-This device allows one to capture a region of an X11 display.
-
-The filename passed as input has the syntax:
-@example
-[@var{hostname}]:@var{display_number}.@var{screen_number}[+@var{x_offset},@var{y_offset}]
-@end example
-
-@var{hostname}:@var{display_number}.@var{screen_number} specifies the
-X11 display name of the screen to grab from. @var{hostname} can be
-omitted, and defaults to "localhost". The environment variable
-@env{DISPLAY} contains the default display name.
-
-@var{x_offset} and @var{y_offset} specify the offsets of the grabbed
-area with respect to the top-left border of the X11 screen. They
-default to 0.
-
-Check the X11 documentation (e.g. man X) for more detailed information.
-
-Use the @command{dpyinfo} program for getting basic information about the
-properties of your X11 display (e.g. grep for "name" or "dimensions").
-
-For example to grab from @file{:0.0} using @command{ffmpeg}:
-@example
-ffmpeg -f x11grab -framerate 25 -video_size cif -i :0.0 out.mpg
-@end example
-
-Grab at position @code{10,20}:
-@example
-ffmpeg -f x11grab -framerate 25 -video_size cif -i :0.0+10,20 out.mpg
-@end example
-
-@subsection Options
-
-@table @option
-@item draw_mouse
-Specify whether to draw the mouse pointer. A value of @code{0} specify
-not to draw the pointer. Default value is @code{1}.
-
-@item follow_mouse
-Make the grabbed area follow the mouse. The argument can be
-@code{centered} or a number of pixels @var{PIXELS}.
-
-When it is specified with "centered", the grabbing region follows the mouse
-pointer and keeps the pointer at the center of region; otherwise, the region
-follows only when the mouse pointer reaches within @var{PIXELS} (greater than
-zero) to the edge of region.
-
-For example:
-@example
-ffmpeg -f x11grab -follow_mouse centered -framerate 25 -video_size cif -i :0.0 out.mpg
-@end example
-
-To follow only when the mouse pointer reaches within 100 pixels to edge:
-@example
-ffmpeg -f x11grab -follow_mouse 100 -framerate 25 -video_size cif -i :0.0 out.mpg
-@end example
-
-@item framerate
-Set the grabbing frame rate. Default value is @code{ntsc},
-corresponding to a frame rate of @code{30000/1001}.
-
-@item show_region
-Show grabbed region on screen.
-
-If @var{show_region} is specified with @code{1}, then the grabbing
-region will be indicated on screen. With this option, it is easy to
-know what is being grabbed if only a portion of the screen is grabbed.
-
-For example:
-@example
-ffmpeg -f x11grab -show_region 1 -framerate 25 -video_size cif -i :0.0+10,20 out.mpg
-@end example
-
-With @var{follow_mouse}:
-@example
-ffmpeg -f x11grab -follow_mouse centered -show_region 1 -framerate 25 -video_size cif -i :0.0 out.mpg
-@end example
-
-@item video_size
-Set the video frame size. Default value is @code{vga}.

-FFmpeg uses Trac for tracking issues, new issues and changes to
-existing issues can be done through a web interface.
-
-Issues can be different kinds of things we want to keep track of
-but that do not belong into the source tree itself. This includes
-bug reports, feature requests and license violations. We
-might add more items to this list in the future, so feel free to
-propose a new `type of issue' on the ffmpeg-devel mailing list if
-you feel it is worth tracking.

+your reply like:
+Re: [issue94] register_avcodec and allcodecs.h [type=patch;status=open;substatus=approved]
+Roundup will then change things as you requested and remove the [...] from

-bug / defect
+bug
     An error, flaw, mistake, failure, or fault in FFmpeg or libav* that

-feature request / enhancement
+feature request
     Request of support for encoding or decoding of a new codec, container
     or variant.
     Request of support for more, less or plain different output or behavior
     where the current implementation cannot be considered wrong.
 
-license violation
-    ticket to keep track of (L)GPL violations of ffmpeg by others
