+All the numerical options, if not specified otherwise, accept in input
+a string representing a number, which may contain one of the
+International System number postfixes, for example 'K', 'M', 'G'.
+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.
+
+Options which do not take arguments are boolean options, and set the
+corresponding value to true. They can be set to false by prefixing
+with "no" the option name, for example using "-nofoo" in the
+command line will set to false the boolean option with name "foo".
+
+@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) does a given option belong 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} option contains
+@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, the option is then 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: 'v' for video, 'a' for audio, 's' for subtitle,
+'d' for data and 't' for attachments. If @var{stream_index} is given, then
+matches stream number @var{stream_index} of this type. Otherwise matches all
+streams of this type.
+@item p:@var{program_id}[:@var{stream_index}]
+If @var{stream_index} is given, then matches stream number @var{stream_index} in
+program with id @var{program_id}. Otherwise matches all streams in this program.
+@item #@var{stream_id}
+Matches the stream by format-specific ID.

+By default the program logs to stderr, if coloring is supported by the
+terminal, colors are used to mark errors and warnings. Log coloring
+can be disabled setting the environment variable
+@env{AV_LOG_FORCE_NOCOLOR} or @env{NO_COLOR}, or can be forced setting
+the environment variable @env{AV_LOG_FORCE_COLOR}.
+The use of the environment variable @env{NO_COLOR} is deprecated and

+This file can be useful for bug reports.
+It also implies @code{-loglevel verbose}.

+
+@end table
+
+@section AVOptions
+
+These options are provided directly by the libavformat, libavdevice and
+libavcodec libraries. To see the list of available AVOptions, use the
+@option{-help} option. They are separated into two categories:
+@table @option
+@item generic
+These options can be set for any container, codec or device. Generic options
+are listed under AVFormatContext options for containers/devices and under
+AVCodecContext options for codecs.
+@item private
+These options are specific to the given container, device or codec. Private
+options are listed under their corresponding containers/devices/codecs.
+@end table
+
+For example to write an ID3v2.3 header instead of a default ID3v2.4 to
+an MP3 file, use the @option{id3v2_version} private option of the MP3
+muxer:
+@example
+ffmpeg -i input.flac -id3v2_version 3 out.mp3
+@end example
+
+All codec AVOptions are obviously per-stream, so the chapter on stream
+specifiers applies to them
+
+Note @option{-nooption} syntax cannot be used for boolean AVOptions,
+use @option{-option 0}/@option{-option 1}.
+
+Note2 old undocumented way of specifying per-stream AVOptions by prepending
+v/a/s to the options name is now obsolete and will be removed soon.

-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.

+The option "-formats" of the ff* tools will display the list of

 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.

-@item
-    Configure to compile with instrumentation enabled:
-    @code{configure --toolchain=gcov}.

-@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

-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

+@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:
+@table @option
+@item sinh(x)
+Compute hyperbolic sine of @var{x}.
+
+@item cosh(x)
+Compute hyperbolic cosine of @var{x}.
+
+@item tanh(x)
+Compute hyperbolic tangent of @var{x}.
+
+@item sin(x)
+Compute sine of @var{x}.
+
+@item cos(x)
+Compute cosine of @var{x}.
+
+@item tan(x)
+Compute tangent of @var{x}.
+
+@item atan(x)
+Compute arctangent of @var{x}.
+
+@item asin(x)
+Compute arcsine of @var{x}.
+
+@item acos(x)
+Compute arccosine of @var{x}.
+
+@item exp(x)
+Compute exponential of @var{x} (with base @code{e}, the Euler's number).
+
+@item log(x)
+Compute natural logarithm of @var{x}.
+
+@item abs(x)
+Compute absolute value of @var{x}.
+
+@item squish(x)
+Compute expression @code{1/(1 + exp(4*x))}.
+
+@item gauss(x)
+Compute Gauss function of @var{x}, corresponding to
+@code{exp(-x*x/2) / sqrt(2*PI)}.
+
+@item isinf(x)
+Return 1.0 if @var{x} is +/-INFINITY, 0.0 otherwise.
+
+@item isnan(x)
+Return 1.0 if @var{x} is NAN, 0.0 otherwise.
+
+@item mod(x, y)
+Compute the remainder of division of @var{x} by @var{y}.
+
+@item max(x, y)
+Return the maximum between @var{x} and @var{y}.
+
+@item min(x, y)
+Return the maximum between @var{x} and @var{y}.
+
+@item eq(x, y)
+Return 1 if @var{x} and @var{y} are equivalent, 0 otherwise.
+
+@item gte(x, y)
+Return 1 if @var{x} is greater than or equal to @var{y}, 0 otherwise.
+
+@item gt(x, y)
+Return 1 if @var{x} is greater than @var{y}, 0 otherwise.
+
+@item lte(x, y)
+Return 1 if @var{x} is lesser than or equal to @var{y}, 0 otherwise.
+
+@item lt(x, y)
+Return 1 if @var{x} is lesser than @var{y}, 0 otherwise.
+
+@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.
+f() must be continuous or the result is undefined.
+@end table
+
+The following constants are available:
+@table @option
+@item PI
+area of the unit disc, approximately 3.14
+@item E
+exp(1) (Euler's number), approximately 2.718
+@item PHI
+golden ratio (1+sqrt(5))/2, approximately 1.618
+@end table
+
+Assuming that an expression is considered "true" if it has a non-zero
+value, note that:
+
+@code{*} works like AND
+
+@code{+} works like OR
+
+and the construct:
+@example
+if A then B else C
+@end example
+is equivalent to
+@example
+if(A,B) + ifnot(A,C)
+@end example
+
+In your C code, you can extend the list of unary and binary functions,
+and define recognized constants, so that they are available for your
+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.

-
-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
-doc/examples and run a command such as PKG_CONFIG_PATH=pc-uninstalled make.

-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}]

-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

-
-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

-FFM is version specific, and there is limited compatibility of FFM files

-ffmpeg/ffserver. It may work but it is not guaranteed to work.

-FFM2 is extensible while maintaining compatibility and should work between

-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.

-@example
-ffmpeg -i input.flac -id3v2_version 3 out.mp3

-
-All codec AVOptions are per-stream, and thus a stream specifier

-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

-The libswresample library performs highly optimized audio resampling,

-
-Specifically, this library performs the following conversions:
-
-@itemize
-@item
-@emph{Resampling}: is the process of changing the audio rate, for
-example from a high sample rate of 44100Hz to 8000Hz. Audio
-conversion from high to low sample rate is a lossy process. Several
-resampling options and algorithms are available.
-
-@item
-@emph{Format conversion}: is the process of converting the type of
-samples, for example from 16-bit signed samples to unsigned 8-bit or
-float samples. It also handles packing conversion, when passing from
-packed layout (all samples belonging to distinct channels interleaved
-in the same buffer), to planar layout (all samples belonging to the
-same channel stored in a dedicated buffer or "plane").
-
-@item
-@emph{Rematrixing}: is the process of changing the channel layout, for
-example from stereo to mono. When the input channels cannot be mapped
-to the output streams, the process is lossy, since it involves
-different gain factors and mixing.
-@end itemize
-
-Various other audio conversions (e.g. stretching and padding) are
-enabled through dedicated options.

 special in that that each image frame consists of three files, for
 each of the YUV420P components. To read or write this image file format,

+hash.
+
+The output of the muxer consists of a single line of the form:
+MD5=@var{MD5}, where @var{MD5} is a hexadecimal number representing
+the computed MD5 hash.
+

+@section MOV/MP4/ISMV
+
+The mov/mp4/ismv muxer supports fragmentation. Normally, a MOV/MP4
+file has all the metadata about all packets stored in one location
+(written at the end of the file, it can be moved to the start for
+better playback using the @command{qt-faststart} tool). A fragmented
+file consists of a number of fragments, where packets and metadata
+about these packets are stored together. Writing a fragmented
+file has the advantage that the file is decodable even if the
+writing is interrupted (while a normal MOV/MP4 is undecodable if
+it is not properly finished), and it requires less memory when writing
+very long files (since writing normal MOV/MP4 files stores info about
+every single packet in memory until the file is closed). The downside
+is that it is less compatible with other applications.
+
+Fragmentation is enabled by setting one of the AVOptions that define
+how to cut the file into fragments:
+
+@table @option
+@item -moov_size @var{bytes}
+Reserves space for the moov atom at the beginning of the file instead of placing the
+moov atom at the end. If the space reserved is insufficient, muxing will fail.
+@item -movflags frag_keyframe
+Start a new fragment at each video keyframe.
+@item -frag_duration @var{duration}
+Create fragments that are @var{duration} microseconds long.
+@item -frag_size @var{size}
+Create fragments that contain up to @var{size} bytes of payload data.
+@item -movflags frag_custom
+Allow the caller to manually choose when to cut fragments, by
+calling @code{av_write_frame(ctx, NULL)} to write a fragment with
+the packets written so far. (This is only useful with other
+applications integrating libavformat, not from @command{ffmpeg}.)
+@item -min_frag_duration @var{duration}
+Don't create fragments that are shorter than @var{duration} microseconds long.
+@end table
+
+If more than one condition is specified, fragments are cut when
+one of the specified conditions is fulfilled. The exception to this is
+@code{-min_frag_duration}, which has to be fulfilled for any of the other
+conditions to apply.
+
+Additionally, the way the output file is written can be adjusted
+through a few other options:
+
+@table @option
+@item -movflags empty_moov
+Write an initial moov atom directly at the start of the file, without
+describing any samples in it. Generally, an mdat/moov pair is written
+at the start of the file, as a normal MOV/MP4 file, containing only
+a short portion of the file. With this option set, there is no initial
+mdat atom, and the moov atom only describes the tracks but has
+a zero duration.
+
+Files written with this option set do not work in QuickTime.
+This option is implicitly set when writing ismv (Smooth Streaming) files.
+@item -movflags separate_moof
+Write a separate moof (movie fragment) atom for each track. Normally,
+packets for all tracks are written in a moof atom (which is slightly
+more efficient), but with this option set, the muxer writes one moof/mdat
+pair for each track, making it easier to separate tracks.

+Basic stream segmenter.
+
+The segmenter muxer outputs streams to a number of separate files of nearly
+fixed duration. Output filename pattern can be set in a fashion similar to
+@ref{image2}.
+
+@code{stream_segment} is a variant of the muxer used to write to
+streaming output formats, i.e. which do not require global headers,
+and is recommended for outputting e.g. to MPEG transport stream segments.
+@code{ssegment} is a shorter alias for @code{stream_segment}.
+
+Every segment starts with a video keyframe, if a video stream is present.
+Note that if you want accurate splitting for a video file, you need to
+make the input key frames correspond to the exact splitting times
+expected by the segmenter, or the segment muxer will start the new
+segment with the key frame found next after the specified start
+time.
+
+The segment muxer works best with a single constant frame rate video.
+
+Optionally it can generate a list of the created segments, by setting
+the option @var{segment_list}. The list type is specified by the
+@var{segment_list_type} option.

+Set flags affecting the segment list generation.
 
-@item reserve_index_space
-By default, this muxer writes the index for seeking (called cues in Matroska
-terms) at the end of the file, because it cannot know in advance how much space
-to leave for the index at the beginning of the file. However for some use cases
--- e.g.  streaming where seeking is possible but slow -- it is useful to put the
-index at the beginning of the file.
+It currently supports the following flags:
+@table @var
+@item cache
+Allow caching (only affects M3U8 list files).
 
-If this option is set to a non-zero value, the muxer will reserve a given amount
-of space in the file header and then try to write the cues there when the muxing
-finishes. If the available space does not suffice, muxing will fail. A safe size
-for most use cases should be about 50kB per hour of video.
-
-Note that cues are only written if the output is seekable and this option will
-have no effect if it is not.
+@item live

-
-MPEG transport stream muxer.
-
-This muxer implements ISO 13818-1 and part of ETSI EN 300 468.
-
-The muxer options are:
-
-@table @option
-@item -mpegts_original_network_id @var{number}
-Set the original_network_id (default 0x0001). This is unique identifier
-of a network in DVB. Its main use is in the unique identification of a
-service through the path Original_Network_ID, Transport_Stream_ID.
-@item -mpegts_transport_stream_id @var{number}
-Set the transport_stream_id (default 0x0001). This identifies a
-transponder in DVB.
-@item -mpegts_service_id @var{number}
-Set the service_id (default 0x0001) also known as program in DVB.
-@item -mpegts_pmt_start_pid @var{number}
-Set the first PID for PMT (default 0x1000, max 0x1f00).
-@item -mpegts_start_pid @var{number}
-Set the first PID for data packets (default 0x0100, max 0x0f00).
-@item -mpegts_m2ts_mode @var{number}
-Enable m2ts mode if set to 1. Default value is -1 which disables m2ts mode.
-@item -muxrate @var{number}
-Set muxrate.
-@item -pes_payload_size @var{number}
-Set minimum PES packet payload in bytes.
-@item -mpegts_flags @var{flags}
-Set flags (see below).
-@item -mpegts_copyts @var{number}
-Preserve original timestamps, if value is set to 1. Default value is -1, which
-results in shifting timestamps so that they start from 0.
-@item -tables_version @var{number}
-Set PAT, PMT and SDT version (default 0, valid values are from 0 to 31, inclusively).
-This option allows updating stream structure so that standard consumer may
-detect the change. To do so, reopen output AVFormatContext (in case of API
-usage) or restart ffmpeg instance, cyclically changing tables_version value:
-@example
-ffmpeg -i source1.ts -codec copy -f mpegts -tables_version 0 udp://1.1.1.1:1111
-ffmpeg -i source2.ts -codec copy -f mpegts -tables_version 1 udp://1.1.1.1:1111

-ffmpeg -i source2.ts -codec copy -f mpegts -tables_version 1 udp://1.1.1.1:1111
-...
-@end example
-@end table
-
-Option mpegts_flags may take a set of such flags:
-
-@table @option
-@item resend_headers
-Reemit PAT/PMT before writing the next packet.
-@item latm
-Use LATM packetization for AAC.
-@end table
-
-The recognized metadata settings in mpegts muxer are @code{service_provider}
-and @code{service_name}. If they are not set the default for
-@code{service_provider} is "FFmpeg" and the default for
-@code{service_name} is "Service01".
-
-@example
-ffmpeg -i file.mpg -c copy \
-     -mpegts_original_network_id 0x1122 \
-     -mpegts_transport_stream_id 0x3344 \

-
-@section null
-
-Null muxer.
-
-This muxer does not generate any output file, it is mainly useful for
-testing or benchmarking purposes.
-
-For example to benchmark decoding with @command{ffmpeg} you can use the
-command:
-@example
-ffmpeg -benchmark -i INPUT -f null out.null
-@end example
-
-Note that the above command does not read or write the @file{out.null}
-file, but specifying the output file is required by the @command{ffmpeg}
-syntax.
-
-Alternatively you can write the command as:
-@example
-ffmpeg -benchmark -i INPUT -f null -
-@end example
-
-@section ogg
-
-Ogg container muxer.
-
-@table @option
-@item -page_duration @var{duration}
-Preferred page duration, in microseconds. The muxer will attempt to create
-pages that are approximately @var{duration} microseconds long. This allows the
-user to compromise between seek granularity and container overhead. The default
-is 1 second. A value of 0 will fill all segments, making pages as large as
-possible. A value of 1 will effectively use 1 packet-per-page in most
-situations, giving a small seek granularity at the cost of additional container
-overhead.
-@end table
-
-@section segment, stream_segment, ssegment
-
-Basic stream segmenter.
-
-The segmenter muxer outputs streams to a number of separate files of nearly
-fixed duration. Output filename pattern can be set in a fashion similar to
-@ref{image2}.
-
-@code{stream_segment} is a variant of the muxer used to write to
-streaming output formats, i.e. which do not require global headers,
-and is recommended for outputting e.g. to MPEG transport stream segments.
-@code{ssegment} is a shorter alias for @code{stream_segment}.
-
-Every segment starts with a keyframe of the selected reference stream,
-which is set through the @option{reference_stream} option.
-
-Note that if you want accurate splitting for a video file, you need to
-make the input key frames correspond to the exact splitting times
-expected by the segmenter, or the segment muxer will start the new
-segment with the key frame found next after the specified start
-time.
-
-The segment muxer works best with a single constant frame rate video.
-
-Optionally it can generate a list of the created segments, by setting
-the option @var{segment_list}. The list type is specified by the
-@var{segment_list_type} option.
-
-The segment muxer supports the following options:
-
-@table @option
-@item reference_stream @var{specifier}
-Set the reference stream, as specified by the string @var{specifier}.
-If @var{specifier} is set to @code{auto}, the reference is choosen
-automatically. Otherwise it must be a stream specifier (see the ``Stream
-specifiers'' chapter in the ffmpeg manual) which specifies the
-reference stream. The default value is @code{auto}.
-
-@item segment_format @var{format}
-Override the inner container format, by default it is guessed by the filename
-extension.
-
-@item segment_list @var{name}
-Generate also a listfile named @var{name}. If not specified no
-listfile is generated.
-
-@item segment_list_flags @var{flags}
-Set flags affecting the segment list generation.
-
-It currently supports the following flags:
-@table @samp
-@item cache
-Allow caching (only affects M3U8 list files).
-
-@item live
-Allow live-friendly file generation.
-@end table
-
-Default value is @code{samp}.
-
-@item segment_list_size @var{size}
-Update the list file so that it contains at most the last @var{size}
-segments. If 0 the list file will contain all the segments. Default
-value is 0.
-
-@item segment_list_type @var{type}
-Specify the format for the segment list file.
-
-The following values are recognized:
-@table @samp
-@item flat
-Generate a flat list for the created segments, one segment per line.
-
-@item csv, ext
-Generate a list for the created segments, one segment per line,
-each line matching the format (comma-separated values):
-@example
-@var{segment_filename},@var{segment_start_time},@var{segment_end_time}
-@end example
-
-@var{segment_filename} is the name of the output file generated by the
-muxer according to the provided pattern. CSV escaping (according to
-RFC4180) is applied if required.
-
-@var{segment_start_time} and @var{segment_end_time} specify
-the segment start and end time expressed in seconds.
-
-A list file with the suffix @code{".csv"} or @code{".ext"} will
-auto-select this format.
-
-@samp{ext} is deprecated in favor or @samp{csv}.
-
-@item ffconcat
-Generate an ffconcat file for the created segments. The resulting file
-can be read using the FFmpeg @ref{concat} demuxer.
-
-A list file with the suffix @code{".ffcat"} or @code{".ffconcat"} will
-auto-select this format.
-
-@item m3u8
-Generate an extended M3U8 file, version 3, compliant with
-@url{http://tools.ietf.org/id/draft-pantos-http-live-streaming}.
-
-A list file with the suffix @code{".m3u8"} will auto-select this format.
-@end table
-
-If not specified the type is guessed from the list file name suffix.
-
-@item segment_time @var{time}
-Set segment duration to @var{time}, the value must be a duration
-specification. Default value is "2". See also the
-@option{segment_times} option.
-
-Note that splitting may not be accurate, unless you force the
-reference stream key-frames at the given time. See the introductory
-notice and the examples below.
-
-@item segment_time_delta @var{delta}
-Specify the accuracy time when selecting the start time for a
-segment, expressed as a duration specification. Default value is "0".
-
-When delta is specified a key-frame will start a new segment if its
-PTS satisfies the relation:
-@example
-PTS >= start_time - time_delta
-@end example
-
-This option is useful when splitting video content, which is always
-split at GOP boundaries, in case a key frame is found just before the
-specified split time.
-
-In particular may be used in combination with the @file{ffmpeg} option
-@var{force_key_frames}. The key frame times specified by
-@var{force_key_frames} may not be set accurately because of rounding
-issues, with the consequence that a key frame time may result set just
-before the specified time. For constant frame rate videos a value of
-1/2*@var{frame_rate} should address the worst case mismatch between
-the specified time and the time set by @var{force_key_frames}.
-
-@item segment_times @var{times}
-Specify a list of split points. @var{times} contains a list of comma
-separated duration specifications, in increasing order. See also
-the @option{segment_time} option.
-
-@item segment_frames @var{frames}
-Specify a list of split video frame numbers. @var{frames} contains a
-list of comma separated integer numbers, in increasing order.
-
-This option specifies to start a new segment whenever a reference
-stream key frame is found and the sequential number (starting from 0)
-of the frame is greater or equal to the next value in the list.
-
-@item segment_wrap @var{limit}
-Wrap around segment index once it reaches @var{limit}.
-
-@item segment_start_number @var{number}
-Set the sequence number of the first segment. Defaults to @code{0}.
-
-@item reset_timestamps @var{1|0}
-Reset timestamps at the begin of each segment, so that each segment
-will start with near-zero timestamps. It is meant to ease the playback
-of the generated segments. May not work with some combinations of
-muxers/codecs. It is set to @code{0} by default.
-
-@item initial_offset @var{offset}
-Specify timestamp offset to apply to the output packet timestamps. The
-argument must be a time duration specification, and defaults to 0.

-@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).
-
-Muxer 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.
-
-The following special options are also recognized:
-@table @option
-@item f
-Specify the format name. Useful if it cannot be guessed from the
-output name suffix.
-
-@item bsfs[/@var{spec}]
-Specify a list of bitstream filters to apply to the specified
-output. It is possible to specify to which streams a given bitstream
-filter applies, by appending a stream specifier to the option
-separated by @code{/}. If the stream specifier is not specified, the
-bistream filters will be applied to all streams in the output.
-
-Several bitstream filters can be specified, separated by ",".
-
-@item select
-Select the streams that should be mapped to the slave output,
-specified by a stream specifier. If not specified, this defaults to
-all the input streams.
-@end table
-
-Some examples follow.
-@itemize
-@item
-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
-
-@item
-Use @command{ffmpeg} to encode the input, and send the output
-to three different destinations. The @code{dump_extra} bitstream
-filter is used to add extradata information to all the output video
-keyframes packets, as requested by the MPEG-TS format. The select
-option is applied to @file{out.aac} in order to make it contain only
-audio packets.
-@example
-ffmpeg -i ... -map 0 -flags +global_header -c:v libx264 -c:a aac -strict experimental
-       -f tee "[bsfs/v=dump_extra]out.ts|[movflags=+faststart]out.mp4|[select=a]out.aac"
-@end example
-@end itemize
-
-Note: some codecs may need different options depending on the output format;

-@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,
-the official specification shall prevail.

-@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.

-FFmpeg can be built with MSVC or ICL using a C99-to-C89 conversion utility and

-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
+
+@item Build your application, everything should work.
+
+@end enumerate
+
+@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.
