-external libraries
-==================
 
-FFmpeg can be combined with a number of external libraries, which sometimes
-affect the licensing of binaries resulting from the combination.
+external libraries:
+-------------------
 
-compatible 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.
 
-The following libraries are under GPL:
-    - frei0r
-    - libcdio
-    - libutvideo
-    - libvidstab
-    - libx264
-    - libxavs
-    - libxvid
-When combining them with FFmpeg, FFmpeg needs to be licensed as GPL as well by
-passing --enable-gpl to configure.
+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.
 
-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 libfaac and libaacplus can be hooked up in FFmpeg.
+You need to pass --enable-nonfree to configure to enable it. Employ this option
+with care as FFmpeg then becomes nonfree and unredistributable.

+Image file demuxer.
+
+This demuxer reads from a list of image files specified by a pattern.
+
+The 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 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 0 and 4, all the following numbers must
+be sequential. This limitation may be hopefully fixed.
+
+The pattern may contain a suffix which is used to automatically
+determine the format of the images contained in the files.
+
+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.
+
+The size, the pixel format, and the format of each image must be the
+same for all the files in the sequence.
+
+The following example shows how to 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

-
-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.
-

-
-@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.

-
-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.

-
-@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

-the file list specified by the pattern must contain a number
-inclusively contained between @var{start_number} and

-numbers must be sequential.
-
-For example the pattern "img-%03d.bmp" will match a sequence of

-@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.

+@chapter Expression Evaluation
+@c man begin EXPRESSION EVALUATION
+
+When evaluating an arithmetic expression, FFmpeg uses an internal
+formula evaluator, implemented through the @file{libavutil/eval.h}
+interface.
+
+An expression may contain unary, binary operators, constants, and
+functions.
+
+Two expressions @var{expr1} and @var{expr2} can be combined to form
+another expression "@var{expr1};@var{expr2}".
+@var{expr1} and @var{expr2} are evaluated in turn, and the new
+expression evaluates to the value of @var{expr2}.
+
+The following binary operators are available: @code{+}, @code{-},
+@code{*}, @code{/}, @code{^}.
+
+The following unary operators are available: @code{+}, @code{-}.
+
+The following functions are available:

+@item log(x)
+@item abs(x)

+@item max(x, y)
+@item min(x, y)
+@item eq(x, y)
+@item gte(x, y)
+@item gt(x, y)
+@item lte(x, y)
+@item lt(x, y)
+@item st(var, expr)
+Allow to store the value of the expression @var{expr} in an internal
+variable. @var{var} specifies the number of the variable where to
+store the value, and it is a value ranging from 0 to 9. The function
+returns the value stored in the internal variable.
+Note, Variables are currently not shared between expressions.
+
+@item ld(var)
+Allow to load the value of the internal variable with number
+@var{var}, which was previously stored with st(@var{var}, @var{expr}).
+The function returns the loaded value.
+
+@item while(cond, expr)
+Evaluate expression @var{expr} while the expression @var{cond} is
+non-zero, and returns the value of the last @var{expr} evaluation, or
+NAN if @var{cond} was always false.
+
+@item ceil(expr)
+Round the value of expression @var{expr} upwards to the nearest
+integer. For example, "ceil(1.5)" is "2.0".
+
+@item floor(expr)
+Round the value of expression @var{expr} downwards to the nearest
+integer. For example, "floor(-1.5)" is "-2.0".
+
+@item trunc(expr)
+Round the value of expression @var{expr} towards zero to the nearest
+integer. For example, "trunc(-1.5)" is "-1.0".
+
+@item sqrt(expr)
+Compute the square root of @var{expr}. This is equivalent to
+"(@var{expr})^.5".
+
+@item not(expr)
+Return 1.0 if @var{expr} is zero, 0.0 otherwise.
+
+@item pow(x, y)
+Compute the power of @var{x} elevated @var{y}, it is equivalent to
+"(@var{x})^(@var{y})".
+
+@item random(x)
+Return a pseudo random value between 0.0 and 1.0. @var{x} is the index of the
+internal variable which will be used to save the seed/state.
+
+@item hypot(x, y)
+This function is similar to the C function with the same name; it returns
+"sqrt(@var{x}*@var{x} + @var{y}*@var{y})", the length of the hypotenuse of a
+right triangle with sides of length @var{x} and @var{y}, or the distance of the
+point (@var{x}, @var{y}) from the origin.
+
+@item gcd(x, y)
+Return the greatest common divisor of @var{x} and @var{y}. If both @var{x} and
+@var{y} are 0 or either or both are less than zero then behavior is undefined.
+
+@item if(x, y)
+Evaluate @var{x}, and if the result is non-zero return the result of
+the evaluation of @var{y}, return 0 otherwise.
+
+@item ifnot(x, y)
+Evaluate @var{x}, and if the result is zero return the result of the
+evaluation of @var{y}, return 0 otherwise.
+
+@item taylor(expr, x) taylor(expr, x, id)
+Evaluate a taylor series at x.
+expr represents the LD(id)-th derivates of f(x) at 0. If id is not specified
+then 0 is assumed.
+note, when you have the derivatives at y instead of 0
+taylor(expr, x-y) can be used
+When the series does not converge the results are undefined.
+
+@item root(expr, max)
+Finds x where f(x)=0 in the interval 0..max.

+expressions.
+
+The evaluator also recognizes the International System number
+postfixes. If 'i' is appended after the postfix, powers of 2 are used
+instead of powers of 10. The 'B' postfix multiplies the value for 8,
+and can be appended after another postfix or used alone. This allows
+using for example 'KB', 'MiB', 'G' and 'B' as postfix.
+
+Follows the list of available International System postfixes, with
+indication of the corresponding powers of 10 and of 2.

-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.
-
-
-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.
-
-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 you can go into the
-doc/examples and run a command such as PKG_CONFIG_PATH=pc-uninstalled make.

-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

-Additionally, you can use the @code{concat} protocol instead of @code{cat} or

-@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

-@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.

+No. Microsoft Visual C++ is not compliant to the C99 standard and does

+There have been efforts to make FFmpeg compatible with MSVC++ in the

-@chapter Detailed description
-@c man begin DETAILED DESCRIPTION
-
-The transcoding process in @command{ffmpeg} for each output can be described by
-the following diagram:
-
-@example
- _______              ______________               _________              ______________            ________
-|       |            |              |             |         |            |              |          |        |
-| input |  demuxer   | encoded data |   decoder   | decoded |  encoder   | encoded data |  muxer   | output |
-| file  | ---------> | packets      |  ---------> | frames  | ---------> | packets      | -------> | file   |
-|_______|            |______________|             |_________|            |______________|          |________|
-
-@end example
-
-@command{ffmpeg} calls the libavformat library (containing demuxers) to read
-input files and get packets containing encoded data from them. When there are
-multiple input files, @command{ffmpeg} tries to keep them synchronized by
-tracking lowest timestamp on any active input stream.
-
-Encoded packets are then passed to the decoder (unless streamcopy is selected
-for the stream, see further for a description). The decoder produces
-uncompressed frames (raw video/PCM audio/...) which can be processed further by
-filtering (see next section). After filtering, the frames are passed to the
-encoder, which encodes them and outputs encoded packets. Finally those are
-passed to the muxer, which writes the encoded packets to the output file.
-
-@section Filtering
-Before encoding, @command{ffmpeg} can process raw audio and video frames using
-filters from the libavfilter library. Several chained filters form a filter
-graph. @command{ffmpeg} distinguishes between two types of filtergraphs:
-simple and complex.
-
-@subsection Simple filtergraphs
-Simple filtergraphs are those that have exactly one input and output, both of
-the same type. In the above diagram they can be represented by simply inserting
-an additional step between decoding and encoding:
-
-@example
- _________                        __________              ______________
-|         |                      |          |            |              |
-| decoded |  simple filtergraph  | filtered |  encoder   | encoded data |
-| frames  | -------------------> | frames   | ---------> | packets      |
-|_________|                      |__________|            |______________|
-
-@end example
-
-Simple filtergraphs are configured with the per-stream @option{-filter} option
-(with @option{-vf} and @option{-af} aliases for video and audio respectively).
-A simple filtergraph for video can look for example like this:
-
-@example
- _______        _____________        _______        _____        ________
-|       |      |             |      |       |      |     |      |        |
-| input | ---> | deinterlace | ---> | scale | ---> | fps | ---> | output |
-|_______|      |_____________|      |_______|      |_____|      |________|
-
-@end example
-
-Note that some filters change frame properties but not frame contents. E.g. the
-@code{fps} filter in the example above changes number of frames, but does not
-touch the frame contents. Another example is the @code{setpts} filter, which
-only sets timestamps and otherwise passes the frames unchanged.
-
-@subsection Complex filtergraphs
-Complex filtergraphs are those which cannot be described as simply a linear
-processing chain applied to one stream. This is the case, for example, when the graph has
-more than one input and/or output, or when output stream type is different from
-input. They can be represented with the following diagram:
-
-@example
- _________
-|         |
-| input 0 |\                    __________
-|_________| \                  |          |
-             \   _________    /| output 0 |
-              \ |         |  / |__________|
- _________     \| complex | /
-|         |     |         |/
-| input 1 |---->| filter  |\
-|_________|     |         | \   __________
-               /| graph   |  \ |          |
-              / |         |   \| output 1 |
- _________   /  |_________|    |__________|
-|         | /
-| input 2 |/
-|_________|
-
-@end example
-
-Complex filtergraphs are configured with the @option{-filter_complex} option.
-Note that this option is global, since a complex filtergraph, by its nature,
-cannot be unambiguously associated with a single stream or file.
-
-The @option{-lavfi} option is equivalent to @option{-filter_complex}.
-
-A trivial example of a complex filtergraph is the @code{overlay} filter, which
-has two video inputs and one video output, containing one video overlaid on top
-of the other. Its audio counterpart is the @code{amix} filter.
-
-@section Stream copy
-Stream copy is a mode selected by supplying the @code{copy} parameter to the
-@option{-codec} option. It makes @command{ffmpeg} omit the decoding and encoding
-step for the specified stream, so it does only demuxing and muxing. It is useful
-for changing the container format or modifying container-level metadata. The
-diagram above will, in this case, simplify to this:
-
-@example
- _______              ______________            ________
-|       |            |              |          |        |
-| input |  demuxer   | encoded data |  muxer   | output |
-| file  | ---------> | packets      | -------> | file   |
-|_______|            |______________|          |________|
-
-@end example
-
-Since there is no decoding or encoding, it is very fast and there is no quality
-loss. However, it might not work in some cases because of many factors. Applying
-filters is obviously also impossible, since filters work on uncompressed data.

+When importing an image sequence, -i also supports expanding shell-like

-
 
 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 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.

-@chapter Format Options
-@c man begin FORMAT OPTIONS
-
-The libavformat library provides some generic global options, which
-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

-Forces seeking to enable seek to any mode 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.
-

-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

-Shift timestamps to make them non-negative. A value of 1 enables shifting,
-a value of 0 disables it, the default value of -1 enables shifting
-when required by the target format.
-
-When shifting is enabled, all output timestamps are shifted by the

-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

-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.

-@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

+@end example
 
-@include authors.texi
+splits the stream in two streams, sends one stream through the crop filter
+and the vflip filter before merging it back with the other stream by
+overlaying it on top. You can use the following command to achieve this:
 
-@ignore
+@example
+ffmpeg -i input -vf "[in] split [T1], fifo, [T2] overlay=0:H/2 [out]; [T1] fifo, crop=iw:ih/2:0:ih/2, vflip [T2]" output
+@end example
 
-@setfilename libavfilter
-@settitle multimedia filtering library
+The result will be that in output the top half of the video is mirrored
+onto the bottom half.
 
-@end ignore
+Video filters are loaded using the @var{-vf} option passed to
+@command{ffmpeg} or to @command{ffplay}. Filters in the same linear
+chain are separated by commas. In our example, @var{split, fifo,
+overlay} are in one linear chain, and @var{fifo, crop, vflip} are in
+another. The points where the linear chains join are labeled by names
+enclosed in square brackets. In our example, that is @var{[T1]} and
+@var{[T2]}. The magic labels @var{[in]} and @var{[out]} are the points
+where video is input and output.
+
+Some filters take in input a list of parameters: they are specified
+after the filter name and an equal sign, and are separated each other
+by a semicolon.
+
+There exist so-called @var{source filters} that do not have a video
+input, and we expect in the future some @var{sink filters} that will
+not have video output.
+
+@chapter graph2dot
+
+The @file{graph2dot} program included in the FFmpeg @file{tools}
+directory can be used to parse a filter graph description and issue a
+corresponding textual representation in the dot language.
+
+Invoke the command:
+@example
+graph2dot -h
+@end example
+
+to see how to use @file{graph2dot}.
+
+You can then pass the dot description to the @file{dot} program (from
+the graphviz suite of programs) and obtain a graphical representation
+of the filter graph.
+
+For example the sequence of commands:
+@example
+echo @var{GRAPH_DESCRIPTION} | \
+tools/graph2dot -o graph.tmp && \
+dot -Tpng graph.tmp -o graph.png && \
+display graph.png
+@end example
+
+can be used to create and display an image representing the graph
+described by the @var{GRAPH_DESCRIPTION} string.

-separated duration specifications, in increasing order. See also
-the @option{segment_time} option.
-

-To remux the content of file @file{in.mkv} to a list of segments
-@file{out-000.nut}, @file{out-001.nut}, etc., and write the list of

+ffmpeg -i in.mkv -c copy -map 0 -f segment -list out.list out%03d.nut
 @end example
 
-@item
-As the example above, but segment the input file according to the split
-points specified by the @var{segment_times} option:
+@section mp3
+
+The MP3 muxer writes a raw MP3 stream with an ID3v2 header at the beginning and
+optionally an ID3v1 tag at the end. ID3v2.3 and ID3v2.4 are supported, the
+@code{id3v2_version} option controls which one is used. The legacy ID3v1 tag is
+not written by default, but may be enabled with the @code{write_id3v1} option.
+
+For seekable output the muxer also writes a Xing frame at the beginning, which
+contains the number of frames in the file. It is useful for computing duration
+of VBR files.
+
+The muxer supports writing ID3v2 attached pictures (APIC frames). The pictures
+are supplied to the muxer in form of a video stream with a single packet. There
+can be any number of those streams, each will correspond to a single APIC frame.
+The stream metadata tags @var{title} and @var{comment} map to APIC
+@var{description} and @var{picture type} respectively. See
+@url{http://id3.org/id3v2.4.0-frames} for allowed picture types.
+
+Note that the APIC frames must be written at the beginning, so the muxer will
+buffer the audio frames until it gets all the pictures. It is therefore advised
+to provide the pictures as soon as possible to avoid excessive buffering.
+
+Examples:
+
+Write an mp3 with an ID3v2.3 header and an ID3v1 footer:
 @example
-ffmpeg -i in.mkv -codec copy -map 0 -f segment -segment_list out.csv -segment_times 1,2,3,5,8,13,21 out%03d.nut
+ffmpeg -i INPUT -id3v2_version 3 -write_id3v1 1 out.mp3
 @end example
 
-@item
-As the example above, but use the @command{ffmpeg} @option{force_key_frames}
-option to force key frames in the input at the specified location, together
-with the segment option @option{segment_time_delta} to account for
-possible roundings operated when setting key frame times.
+Attach a picture to an mp3:
 @example
-ffmpeg -i in.mkv -force_key_frames 1,2,3,5,8,13,21 -codec:v mpeg4 -codec:a pcm_s16le -map 0 \
--f segment -segment_list out.csv -segment_times 1,2,3,5,8,13,21 -segment_time_delta 0.05 out%03d.nut
+ffmpeg -i input.mp3 -i cover.png -c copy -metadata:s:v title="Album cover"
+-metadata:s:v comment="Cover (Front)" out.mp3
 @end example
-In order to force key frames on the input file, transcoding is
-required.
-
-@item
-Segment the input file by splitting the input file according to the
-frame numbers sequence specified with the @option{segment_frames} option:
-@example
-ffmpeg -i in.mkv -codec copy -map 0 -f segment -segment_list out.csv -segment_frames 100,200,300,500,800 out%03d.nut

-@end example
-
-@item
-Segment the input file, and create an M3U8 live playlist (can be used
-as live HLS source):

-@section tee
-
-The tee muxer can be used to write the same data to several files or any
-other kind of muxer. It can be used, for example, to both stream a video to
-the network and save it to disk at the same time.
-
-It is different from specifying several outputs to the @command{ffmpeg}
-command-line tool because the audio and video data will be encoded only once
-with the tee muxer; encoding can be a very expensive process. It is not
-useful when using the libavformat API directly because it is then possible
-to feed the same packets to several muxers directly.
-
-The slave outputs are specified in the file name given to the muxer,
-separated by '|'. If any of the slave name contains the '|' separator,
-leading or trailing spaces or any special character, it must be
-escaped (see the ``Quoting and escaping'' section in the ffmpeg-utils
-manual).
-
-Options can be specified for each slave by prepending them as a list of
-@var{key}=@var{value} pairs separated by ':', between square brackets. If
-the options values contain a special character or the ':' separator, they
-must be escaped; note that this is a second level escaping.
-
-Example: encode something and both archive it in a WebM file and stream it
-as MPEG-TS over UDP (the streams need to be explicitly mapped):
-
-@example
-ffmpeg -i ... -c:v libx264 -c:a mp2 -f tee -map 0:v -map 0:a
-  "archive-20121107.mkv|[f=mpegts]udp://10.0.1.255:1234/"
-@end example
-
-Note: some codecs may need different options depending on the output format;
-the auto-detection of this can not work with the tee muxer. The main example
-is the @option{global_header} flag.

-@chapter Description
-NUT is a low overhead generic container format. It stores audio, video,
-subtitle and user-defined streams in a simple, yet efficient, way.
-
-It was created by a group of FFmpeg and MPlayer developers in 2003
-and was finalized in 2008.
-
-The official nut specification is at svn://svn.mplayerhq.hu/nut
-In case of any differences between this text and the official specification,

-
-@section Generic raw YUVA formats
-
-Since many exotic planar YUVA pixel formats are not considered by
-the AVI/QuickTime FourCC lists, the following scheme is adopted for
-representing them.
-
-The first two bytes can contain the values:
-Y1 = only Y
-Y2 = Y+A
-Y3 = YUV
-Y4 = YUVA
-
-The third byte represents the width and height chroma subsampling
-values for the UV planes, that is the amount to shift the luma
-width/height right to find the chroma width/height.
-
-The fourth byte is the number of bits used (8, 16, ...).
-
-If the order of bytes is inverted, that means that each component has
-to be read big-endian.

+@subsection Using static libraries
 
-To set up a proper environment in MSYS, you need to run @code{msys.bat} from
-the Visual Studio or Intel Compiler command prompt.
+Assuming you have just built and installed FFmpeg in @file{/usr/local}:
 
-Place @code{makedef}, @code{c99wrap.exe}, @code{c99conv.exe}, and @code{yasm.exe}
-somewhere in your @code{PATH}.
+@enumerate
 
-Next, make sure @code{inttypes.h} and any other headers and libs you want to use
-are located in a spot that the compiler can see. Do so by modifying the @code{LIB}
-and @code{INCLUDE} environment variables to include the @strong{Windows} paths to
-these directories. Alternatively, you can try and use the
-@code{--extra-cflags}/@code{--extra-ldflags} configure options.
+@item Create a new console application ("File / New / Project") and then
+select "Win32 Console Application". On the appropriate page of the
+Application Wizard, uncheck the "Precompiled headers" option.
 
-Finally, run:
+@item Write the source code for your application, or, for testing, just
+copy the code from an existing sample application into the source file
+that MSVC++ has already created for you. For example, you can copy
+@file{libavformat/output-example.c} from the FFmpeg distribution.
+
+@item Open the "Project / Properties" dialog box. In the "Configuration"
+combo box, select "All Configurations" so that the changes you make will
+affect both debug and release builds. In the tree view on the left hand
+side, select "C/C++ / General", then edit the "Additional Include
+Directories" setting to contain the path where the FFmpeg includes were
+installed (i.e. @file{c:\msys\1.0\local\include}).
+Do not add MinGW's include directory here, or the include files will
+conflict with MSVC's.
+
+@item Still in the "Project / Properties" dialog box, select
+"Linker / General" from the tree view and edit the
+"Additional Library Directories" setting to contain the @file{lib}
+directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
+the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
+and the directory where MinGW's GCC libs are installed
+(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
+"Linker / Input" from the tree view, and add the files @file{libavformat.a},
+@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
+@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
+to the end of "Additional Dependencies".
+
+@item Now, select "C/C++ / Code Generation" from the tree view. Select
+"Debug" in the "Configuration" combo box. Make sure that "Runtime
+Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
+the "Configuration" combo box and make sure that "Runtime Library" is
+set to "Multi-threaded DLL".
+
+@item Click "OK" to close the "Project / Properties" dialog box.
+
+@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
+Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
+and install it in MSVC++'s include directory
+(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
+
+@item MSVC++ also does not understand the @code{inline} keyword used by
+FFmpeg, so you must add this line before @code{#include}ing libav*:
+@example
+#define inline _inline
+@end example
+

+
+@subsection Using shared libraries
+
+This is how to create DLL and LIB files that are compatible with MSVC++:
+
+@enumerate
+
+@item Add a call to @file{vcvars32.bat} (which sets up the environment
+variables for the Visual C++ tools) as the first line of @file{msys.bat}.
+The standard location for @file{vcvars32.bat} is
+@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
+and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
+If this corresponds to your setup, add the following line as the first line
+of @file{msys.bat}:
 
 @example
-For MSVC:
-./configure --toolchain=msvc
+call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
+@end example
 
-For ICL:
-./configure --toolchain=icl
+Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
+and run @file{c:\msys\1.0\msys.bat} from there.
 
+@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
+from @file{Microsoft (R) Library Manager}, this means your environment
+variables are set up correctly, the @file{Microsoft (R) Library Manager}
+is on the path and will be used by FFmpeg to create
+MSVC++-compatible import libraries.
+
+@item Build FFmpeg with
+
+@example
+./configure --enable-shared
 make
 make install
 @end example
 
-If you wish to compile shared libraries, add @code{--enable-shared} to your
-configure options. Note that due to the way MSVC and ICL handle DLL imports and
-exports, you cannot compile static and shared libraries at the same time, and
-enabling shared libraries will automatically disable the static ones.
+Your install path (@file{/usr/local/} by default) should now have the
+necessary DLL and LIB files under the @file{bin} directory.
 
-Notes:
-
-@itemize
-
-@item It is possible that coreutils' @code{link.exe} conflicts with MSVC's linker.
-You can find out by running @code{which link} to see which @code{link.exe} you
-are using. If it is located at @code{/bin/link.exe}, then you have the wrong one
-in your @code{PATH}. Either move or remove that copy, or make sure MSVC's
-@code{link.exe} takes precedence in your @code{PATH} over coreutils'.
-
-@item If you wish to build with zlib support, you will have to grab a compatible
-zlib binary from somewhere, with an MSVC import lib, or if you wish to link
-statically, you can follow the instructions below to build a compatible
-@code{zlib.lib} with MSVC. Regardless of which method you use, you must still
-follow step 3, or compilation will fail.
-@enumerate
-@item Grab the @uref{http://zlib.net/, zlib sources}.
-@item Edit @code{win32/Makefile.msc} so that it uses -MT instead of -MD, since
-this is how FFmpeg is built as well.
-@item Edit @code{zconf.h} and remove its inclusion of @code{unistd.h}. This gets
-erroneously included when building FFmpeg.
-@item Run @code{nmake -f win32/Makefile.msc}.
-@item Move @code{zlib.lib}, @code{zconf.h}, and @code{zlib.h} to somewhere MSVC
-can see.
 @end enumerate
 
-@item FFmpeg has been tested with the following on i686 and x86_64:
-@itemize
-@item Visual Studio 2010 Pro and Express
-@item Visual Studio 2012 Pro and Express
-@item Intel Composer XE 2013
-@end itemize
-Anything else is not officially supported.
+Alternatively, build the libraries with a cross compiler, according to
+the instructions below in @ref{Cross compilation for Windows with Linux}.
 
-@end itemize
+To use those files with MSVC++, do the same as you would do with
+the static libraries, as described above. But in Step 4,
+you should only need to add the directory where the LIB files are installed
+(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
+installed in the @file{bin} directory. And instead of adding the static
+libraries (@file{libxxx.a} files) you should add the MSVC import libraries
+(@file{avcodec.lib}, @file{avformat.lib}, and
+@file{avutil.lib}). Note that you should not use the GCC import
+libraries (@file{libxxx.dll.a} files), as these will give you undefined
+reference errors. There should be no need for @file{libmingwex.a},
+@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
+statically linked into the DLLs.
 
-@subsection Linking to FFmpeg with Microsoft Visual C++
-
-If you plan to link with MSVC-built static libraries, you will need
-to make sure you have @code{Runtime Library} set to
-@code{Multi-threaded (/MT)} in your project's settings.
-
-You will need to define @code{inline} to something MSVC understands:
+FFmpeg headers do not declare global data for Windows DLLs through the usual
+dllexport/dllimport interface. Such data will be exported properly while
+building, but to use them in your MSVC++ code you will have to edit the
+appropriate headers and mark the data as dllimport. For example, in
+libavutil/pixdesc.h you should have:
 @example
-#define inline __inline
+extern __declspec(dllimport) const AVPixFmtDescriptor av_pix_fmt_descriptors[];
 @end example
 
-Also note, that as stated in @strong{Microsoft Visual C++}, you will need
-an MSVC-compatible @uref{http://code.google.com/p/msinttypes/, inttypes.h}.
-
-If you plan on using import libraries created by dlltool, you must
-set @code{References} to @code{No (/OPT:NOREF)} under the linker optimization
-settings, otherwise the resulting binaries will fail during runtime.
-This is not required when using import libraries generated by @code{lib.exe}.
+Note that using import libraries created by dlltool requires
+the linker optimization option to be set to
+"References: Keep Unreferenced Data (@code{/OPT:NOREF})", otherwise
+the resulting binaries will fail during runtime. This isn't
+required when using import libraries generated by lib.exe.
