+FFmpeg:
+-------
+
+Most files in FFmpeg are under the GNU Lesser General Public License version 2.1
+or later (LGPL v2.1+). Read the file COPYING.LGPLv2.1 for details. Some other
+files have MIT/X11/BSD-style licenses. In combination the LGPL v2.1+ applies to
+FFmpeg.
+
+Some optional parts of FFmpeg are licensed under the GNU General Public License
+version 2 or later (GPL v2+). See the file COPYING.GPLv2 for details. None of
+these parts are used by default, you have to explicitly pass --enable-gpl to
+configure to activate them. In this case, FFmpeg's license changes to GPL v2+.
+
+Specifically, the GPL parts of FFmpeg are
+
+- libpostproc
+- some x86 optimizations in libswscale
+- optional x86 optimizations in the files
+  libavcodec/x86/h264_deblock_sse2.asm
+  libavcodec/x86/h264_idct_sse2.asm
+  libavcodec/x86/idct_mmx.c
+- the X11 grabber in libavdevice/x11grab.c
+
+There are a handful of files under other licensing terms, namely:
+
+* The files libavcodec/jfdctfst.c, libavcodec/jfdctint.c, libavcodec/jrevdct.c
+  are taken from libjpeg, see the top of the files for licensing details.
+
+Should you, for whatever reason, prefer to use version 3 of the (L)GPL, then
+the configure parameter --enable-version3 will activate this licensing option
+for you. Read the file COPYING.LGPLv3 or, if you have enabled GPL parts,
+COPYING.GPLv3 to learn the exact legal terms that apply in this case.
+
+
+external libraries:
+-------------------
+
+Some external libraries, e.g. libx264, are under GPL and can be used in
+conjunction with FFmpeg. They require --enable-gpl to be passed to configure
+as well.
+
+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 nonfree external libraries libamrnb, libamrwb and libfaac can be hooked up
+in FFmpeg. You need to pass --enable-nonfree to configure to enable them. Employ
+this option with care as FFmpeg then becomes nonfree and unredistributable.
+Note that libfaac claims to be LGPL, but is not.

-## External libraries
-
-FFmpeg can be combined with a number of external libraries, which sometimes
-affect the licensing of binaries resulting from the combination.
-
-### Compatible libraries
-
-The following libraries are under GPL:
-- frei0r
-- libcdio
-- librubberband
-- libvidstab
-- libx264
-- libx265
-- libxavs
-- libxvid
-
-When combining them with FFmpeg, FFmpeg needs to be licensed as GPL as well by
-passing `--enable-gpl` to configure.
-
-The OpenCORE and VisualOn libraries are under the Apache License 2.0. That
-license is incompatible with the LGPL v2.1 and the GPL v2, but not with
-version 3 of those licenses. So to combine these libraries with FFmpeg, the
-license version needs to be upgraded by passing `--enable-version3` to configure.
-
-### Incompatible libraries
-
-There are certain libraries you can combine with FFmpeg whose licenses are not
-compatible with the GPL and/or the LGPL. If you wish to enable these
-libraries, even in circumstances that their license may be incompatible, pass
-`--enable-nonfree` to configure. This will cause the resulting binary to be
-unredistributable.
-
-The Fraunhofer FDK AAC and OpenSSL libraries are under licenses which are
-incompatible with the GPLv2 and v3. To the best of our knowledge, they are
-compatible with the LGPL.

-FFmpeg README
-=============
-
-FFmpeg is a collection of libraries and tools to process multimedia content
-such as audio, video, subtitles and related metadata.
-
-## Libraries
-
-* `libavcodec` provides implementation of a wider range of codecs.
-* `libavformat` implements streaming protocols, container formats and basic I/O access.
-* `libavutil` includes hashers, decompressors and miscellaneous utility functions.
-* `libavfilter` provides a mean to alter decoded Audio and Video through chain of filters.
-* `libavdevice` provides an abstraction to access capture and playback devices.
-* `libswresample` implements audio mixing and resampling routines.
-* `libswscale` implements color conversion and scaling routines.
-
-## Tools
-
-* [ffmpeg](https://ffmpeg.org/ffmpeg.html) is a command line toolbox to
-  manipulate, convert and stream multimedia content.
-* [ffplay](https://ffmpeg.org/ffplay.html) is a minimalistic multimedia player.
-* [ffprobe](https://ffmpeg.org/ffprobe.html) is a simple analysis tool to inspect
-  multimedia content.
-* Additional small tools such as `aviocat`, `ismindex` and `qt-faststart`.
-
-## Documentation
-
-The offline documentation is available in the **doc/** directory.
-
-The online documentation is available in the main [website](https://ffmpeg.org)

RELEASE

@@ -1 +1,126 @@
-4.2.4
+Release Notes
+=============
+
+* 0.5 "Bike Shed World Domination" March 3, 2009
+
+General notes
+-------------
+
+It has been so long since the last release that this should be considered the
+first FFmpeg release of recent times. Because of the way things have unfolded to
+date, the notes for this version cannot be entirely conventional.
+
+See the Changelog file for a list of significant changes.
+
+Please note that our policy on bug reports has not changed. We still only accept
+bug reports against HEAD of the FFmpeg trunk repository. If you are experiencing
+any issues with any formally released version of FFmpeg, please try a current
+version of the development code to check if the issue still exists. If it does,
+make your report against the development code following the usual bug reporting
+guidelines.
+
+API notes
+---------
+
+In the next release, it is intended to remove a number of deprecated APIs. We
+decided to put out a release that includes said APIs for the benefit of third
+party software.
+
+As such, this release:
+- provides a sync point for said APIs
+- increases awareness of API changes
+- allows the next release to detail how to transition from the old to the new
+
+The deprecated APIs to be removed are:
+- imgconvert (to be replaced by libswscale)
+- vhook (to be replaced by libavfilter)
+
+If at all possible, do not use the deprecated APIs. All notes on API changes
+should appear in doc/APIchanges.
+
+
+
+* 0.5.1 March 2, 2010
+
+General notes
+-------------
+
+This point release includes some minor updates to make the 0.5 release series
+usable for users that need to retain the existing behavior as closely as
+possible. The changes follow below:
+
+Security fixes
+--------------
+
+Various programming errors in container and codec implementations
+may lead to denial of service or the execution of arbitrary code
+if the user is tricked into opening a malformed media file or stream.
+
+Affected and updated have been the implementations of the following
+codecs and container formats:
+
+ - the Vorbis audio codec
+ - the FF Video 1 codec
+ - the MPEG audio codec
+ - the H264 video codec
+ - the MLP codec
+ - the HuffYUV codec
+ - the ASF demuxer
+ - the Ogg container implementation
+ - the MOV container implementation
+
+Symbol Versioning enabled
+-------------------------
+
+The backported symbol versioning change is enabled on platforms that support
+it. This allows users to upgrade from 0.5.1 to the upcoming 0.6 release
+without having to recompile their applications. Please note that distributors
+have to recompile applications against 0.5.1 before upgrading to 0.6.
+
+libx264.c backport
+------------------
+
+This release includes a backport to the libx264 wrapper that allows FFmpeg to
+be compiled against newer versions of libx264 up to API version 85.
+
+licensing changes
+-----------------
+
+Previously both libswscale and our AC-3 decoder had GPLed parts. These have
+been replaced by fresh LGPL code. x86 optimizations for libswscale remain GPL,
+but the C code is fully functional. Optimizations for other architectures have
+been relicensed to LGPL.
+
+AMR-NB decoding/encoding and AMR-WB decoding is now possible through the free
+software OpenCORE libraries as an alternative to the non-free libamr libraries.
+
+We found out that libfaac contains non-free parts and is not LGPL as previously
+claimed. We have changed configure to reflect this. You now have to pass the
+--enable-nonfree option if you wish to compile with libfaac support enabled.
+
+Furthermore the non-free bits in libavcodec/fdctref.c have been rewritten. Note
+well that they were only used in a test program and never compiled into any
+FFmpeg library.
+
+
+
+* 0.5.2 May 25, 2010
+
+General notes
+-------------
+
+This is a maintenance only release that addresses a small number of security
+and portability issues. Distributors and system integrators are encouraged
+to update and share their patches against this branch.
+
+
+
+* 0.5.3 Oct 18, 2010
+
+General notes
+-------------
+
+This is (again) another maintenance only release that addresses a fix
+for seekable HTTP and an exploitable bug in the FLIC decoder
+(cf. CVE-2010-3429 for details). Distributors and system integrators are
+encouraged to update and share their patches against this branch.

-@chapter Bitstream Filters
-@c man begin BITSTREAM FILTERS
-
-When you configure your FFmpeg build, all the supported bitstream
-filters are enabled by default. You can list all available ones using
-the configure option @code{--list-bsfs}.
-
-You can disable all the bitstream filters using the configure option
-@code{--disable-bsfs}, and selectively enable any bitstream filter using
-the option @code{--enable-bsf=BSF}, or you can disable a particular
-bitstream filter using the option @code{--disable-bsf=BSF}.
-
-The option @code{-bsfs} of the ff* tools will display the list of
-all the supported bitstream filters included in your build.
-
-The ff* tools have a -bsf option applied per stream, taking a
-comma-separated list of filters, whose parameters follow the filter
-name after a '='.
-
-@example
-ffmpeg -i INPUT -c:v copy -bsf:v filter1[=opt1=str1:opt2=str2][,filter2] OUTPUT
-@end example
-
-Below is a description of the currently available bitstream filters,
-with their parameters, if any.
-
-@section aac_adtstoasc
-
-Convert MPEG-2/4 AAC ADTS to an MPEG-4 Audio Specific Configuration
-bitstream.
-
-This filter creates an MPEG-4 AudioSpecificConfig from an MPEG-2/4
-ADTS header and removes the ADTS header.
-
-This filter is required for example when copying an AAC stream from a
-raw ADTS AAC or an MPEG-TS container to MP4A-LATM, to an FLV file, or
-to MOV/MP4 files and related formats such as 3GP or M4A. Please note
-that it is auto-inserted for MP4A-LATM and MOV/MP4 and related formats.
-
-@section av1_metadata
-
-Modify metadata embedded in an AV1 stream.
-
-@table @option
-@item td
-Insert or remove temporal delimiter OBUs in all temporal units of the
-stream.
-
-@table @samp
-@item insert
-Insert a TD at the beginning of every TU which does not already have one.
-@item remove
-Remove the TD from the beginning of every TU which has one.
-@end table
-
-@item color_primaries
-@item transfer_characteristics
-@item matrix_coefficients
-Set the color description fields in the stream (see AV1 section 6.4.2).
-
-@item color_range
-Set the color range in the stream (see AV1 section 6.4.2; note that
-this cannot be set for streams using BT.709 primaries, sRGB transfer
-characteristic and identity (RGB) matrix coefficients).
-@table @samp
-@item tv
-Limited range.
-@item pc
-Full range.
-@end table
-
-@item chroma_sample_position
-Set the chroma sample location in the stream (see AV1 section 6.4.2).
-This can only be set for 4:2:0 streams.
-
-@table @samp
-@item vertical
-Left position (matching the default in MPEG-2 and H.264).
-@item colocated
-Top-left position.
-@end table
-
-@item tick_rate
-Set the tick rate (@emph{num_units_in_display_tick / time_scale}) in
-the timing info in the sequence header.
-@item num_ticks_per_picture
-Set the number of ticks in each picture, to indicate that the stream
-has a fixed framerate.  Ignored if @option{tick_rate} is not also set.
-
-@item delete_padding
-Deletes Padding OBUs.
-
-@end table
-
-@section chomp
-
-Remove zero padding at the end of a packet.
-
-@section dca_core
-
-Extract the core from a DCA/DTS stream, dropping extensions such as
-DTS-HD.
-
-@section dump_extra
-
-Add extradata to the beginning of the filtered packets except when
-said packets already exactly begin with the extradata that is intended
-to be added.
-
-@table @option
-@item freq
-The additional argument specifies which packets should be filtered.
-It accepts the values:
-@table @samp
-@item k
-@item keyframe
-add extradata to all key packets
-
-@item e
-@item all
-add extradata to all packets
-@end table
-@end table
-
-If not specified it is assumed @samp{k}.
-
-For example the following @command{ffmpeg} command forces a global
-header (thus disabling individual packet headers) in the H.264 packets
-generated by the @code{libx264} encoder, but corrects them by adding
-the header stored in extradata to the key packets:
-@example
-ffmpeg -i INPUT -map 0 -flags:v +global_header -c:v libx264 -bsf:v dump_extra out.ts
-@end example
-
-@section eac3_core
-
-Extract the core from a E-AC-3 stream, dropping extra channels.
-
-@section extract_extradata
-
-Extract the in-band extradata.
-
-Certain codecs allow the long-term headers (e.g. MPEG-2 sequence headers,
-or H.264/HEVC (VPS/)SPS/PPS) to be transmitted either "in-band" (i.e. as a part
-of the bitstream containing the coded frames) or "out of band" (e.g. on the
-container level). This latter form is called "extradata" in FFmpeg terminology.
-
-This bitstream filter detects the in-band headers and makes them available as
-extradata.
-
-@table @option
-@item remove
-When this option is enabled, the long-term headers are removed from the
-bitstream after extraction.
-@end table
-
-@section filter_units
-
-Remove units with types in or not in a given set from the stream.
-
-@table @option
-@item pass_types
-List of unit types or ranges of unit types to pass through while removing
-all others.  This is specified as a '|'-separated list of unit type values
-or ranges of values with '-'.
-
-@item remove_types
-Identical to @option{pass_types}, except the units in the given set
-removed and all others passed through.
-@end table
-
-Extradata is unchanged by this transformation, but note that if the stream
-contains inline parameter sets then the output may be unusable if they are
-removed.
-
-For example, to remove all non-VCL NAL units from an H.264 stream:
-@example
-ffmpeg -i INPUT -c:v copy -bsf:v 'filter_units=pass_types=1-5' OUTPUT
-@end example
-
-To remove all AUDs, SEI and filler from an H.265 stream:
-@example
-ffmpeg -i INPUT -c:v copy -bsf:v 'filter_units=remove_types=35|38-40' OUTPUT
-@end example
-
-@section hapqa_extract
-
-Extract Rgb or Alpha part of an HAPQA file, without recompression, in order to create an HAPQ or an HAPAlphaOnly file.
-
-@table @option
-@item texture
-Specifies the texture to keep.
-
-@table @option
-@item color
-@item alpha
-@end table
-
-@end table
-
-Convert HAPQA to HAPQ
-@example
-ffmpeg -i hapqa_inputfile.mov -c copy -bsf:v hapqa_extract=texture=color -tag:v HapY -metadata:s:v:0 encoder="HAPQ" hapq_file.mov
-@end example
-
-Convert HAPQA to HAPAlphaOnly
-@example
-ffmpeg -i hapqa_inputfile.mov -c copy -bsf:v hapqa_extract=texture=alpha -tag:v HapA -metadata:s:v:0 encoder="HAPAlpha Only" hapalphaonly_file.mov
-@end example
-
-@section h264_metadata
-
-Modify metadata embedded in an H.264 stream.
-
-@table @option
-@item aud
-Insert or remove AUD NAL units in all access units of the stream.
-
-@table @samp
-@item insert
-@item remove
-@end table
-
-@item sample_aspect_ratio
-Set the sample aspect ratio of the stream in the VUI parameters.
-
-@item video_format
-@item video_full_range_flag
-Set the video format in the stream (see H.264 section E.2.1 and
-table E-2).
-
-@item colour_primaries
-@item transfer_characteristics
-@item matrix_coefficients
-Set the colour description in the stream (see H.264 section E.2.1
-and tables E-3, E-4 and E-5).
-
-@item chroma_sample_loc_type
-Set the chroma sample location in the stream (see H.264 section
-E.2.1 and figure E-1).
-
-@item tick_rate
-Set the tick rate (num_units_in_tick / time_scale) in the VUI
-parameters.  This is the smallest time unit representable in the
-stream, and in many cases represents the field rate of the stream
-(double the frame rate).
-@item fixed_frame_rate_flag
-Set whether the stream has fixed framerate - typically this indicates
-that the framerate is exactly half the tick rate, but the exact
-meaning is dependent on interlacing and the picture structure (see
-H.264 section E.2.1 and table E-6).
-
-@item crop_left
-@item crop_right
-@item crop_top
-@item crop_bottom
-Set the frame cropping offsets in the SPS.  These values will replace
-the current ones if the stream is already cropped.
-
-These fields are set in pixels.  Note that some sizes may not be
-representable if the chroma is subsampled or the stream is interlaced
-(see H.264 section 7.4.2.1.1).
-
-@item sei_user_data
-Insert a string as SEI unregistered user data.  The argument must
-be of the form @emph{UUID+string}, where the UUID is as hex digits
-possibly separated by hyphens, and the string can be anything.
-
-For example, @samp{086f3693-b7b3-4f2c-9653-21492feee5b8+hello} will
-insert the string ``hello'' associated with the given UUID.
-
-@item delete_filler
-Deletes both filler NAL units and filler SEI messages.
-
-@item level
-Set the level in the SPS.  Refer to H.264 section A.3 and tables A-1
-to A-5.
-
-The argument must be the name of a level (for example, @samp{4.2}), a
-level_idc value (for example, @samp{42}), or the special name @samp{auto}
-indicating that the filter should attempt to guess the level from the
-input stream properties.
-
-@end table
-
-@section h264_mp4toannexb
-
-Convert an H.264 bitstream from length prefixed mode to start code
-prefixed mode (as defined in the Annex B of the ITU-T H.264
-specification).
-
-This is required by some streaming formats, typically the MPEG-2
-transport stream format (muxer @code{mpegts}).
-
-For example to remux an MP4 file containing an H.264 stream to mpegts
-format with @command{ffmpeg}, you can use the command:
-
-@example
-ffmpeg -i INPUT.mp4 -codec copy -bsf:v h264_mp4toannexb OUTPUT.ts
-@end example
-
-Please note that this filter is auto-inserted for MPEG-TS (muxer
-@code{mpegts}) and raw H.264 (muxer @code{h264}) output formats.
-
-@section h264_redundant_pps
-
-This applies a specific fixup to some Blu-ray streams which contain
-redundant PPSs modifying irrelevant parameters of the stream which
-confuse other transformations which require correct extradata.
-
-A new single global PPS is created, and all of the redundant PPSs
-within the stream are removed.
-
-@section hevc_metadata
-
-Modify metadata embedded in an HEVC stream.
-
-@table @option
-@item aud
-Insert or remove AUD NAL units in all access units of the stream.
-
-@table @samp
-@item insert
-@item remove
-@end table
-
-@item sample_aspect_ratio
-Set the sample aspect ratio in the stream in the VUI parameters.
-
-@item video_format
-@item video_full_range_flag
-Set the video format in the stream (see H.265 section E.3.1 and
-table E.2).
-
-@item colour_primaries
-@item transfer_characteristics
-@item matrix_coefficients
-Set the colour description in the stream (see H.265 section E.3.1
-and tables E.3, E.4 and E.5).
-
-@item chroma_sample_loc_type
-Set the chroma sample location in the stream (see H.265 section
-E.3.1 and figure E.1).
-
-@item tick_rate
-Set the tick rate in the VPS and VUI parameters (num_units_in_tick /
-time_scale).  Combined with @option{num_ticks_poc_diff_one}, this can
-set a constant framerate in the stream.  Note that it is likely to be
-overridden by container parameters when the stream is in a container.
-
-@item num_ticks_poc_diff_one
-Set poc_proportional_to_timing_flag in VPS and VUI and use this value
-to set num_ticks_poc_diff_one_minus1 (see H.265 sections 7.4.3.1 and
-E.3.1).  Ignored if @option{tick_rate} is not also set.
-
-@item crop_left
-@item crop_right
-@item crop_top
-@item crop_bottom
-Set the conformance window cropping offsets in the SPS.  These values
-will replace the current ones if the stream is already cropped.
-
-These fields are set in pixels.  Note that some sizes may not be
-representable if the chroma is subsampled (H.265 section 7.4.3.2.1).
-
-@item level
-Set the level in the VPS and SPS.  See H.265 section A.4 and tables
-A.6 and A.7.
-
-The argument must be the name of a level (for example, @samp{5.1}), a
-@emph{general_level_idc} value (for example, @samp{153} for level 5.1),
-or the special name @samp{auto} indicating that the filter should
-attempt to guess the level from the input stream properties.
-
-@end table
-
-@section hevc_mp4toannexb
-
-Convert an HEVC/H.265 bitstream from length prefixed mode to start code
-prefixed mode (as defined in the Annex B of the ITU-T H.265
-specification).
-
-This is required by some streaming formats, typically the MPEG-2
-transport stream format (muxer @code{mpegts}).
-
-For example to remux an MP4 file containing an HEVC stream to mpegts
-format with @command{ffmpeg}, you can use the command:
-
-@example
-ffmpeg -i INPUT.mp4 -codec copy -bsf:v hevc_mp4toannexb OUTPUT.ts
-@end example
-
-Please note that this filter is auto-inserted for MPEG-TS (muxer
-@code{mpegts}) and raw HEVC/H.265 (muxer @code{h265} or
-@code{hevc}) output formats.
-
-@section imxdump
-
-Modifies the bitstream to fit in MOV and to be usable by the Final Cut
-Pro decoder. This filter only applies to the mpeg2video codec, and is
-likely not needed for Final Cut Pro 7 and newer with the appropriate
-@option{-tag:v}.
-
-For example, to remux 30 MB/sec NTSC IMX to MOV:
-
-@example
-ffmpeg -i input.mxf -c copy -bsf:v imxdump -tag:v mx3n output.mov
-@end example
-
-@section mjpeg2jpeg
-
-Convert MJPEG/AVI1 packets to full JPEG/JFIF packets.
-
-MJPEG is a video codec wherein each video frame is essentially a
-JPEG image. The individual frames can be extracted without loss,
-e.g. by
-
-@example
-ffmpeg -i ../some_mjpeg.avi -c:v copy frames_%d.jpg
-@end example
-
-Unfortunately, these chunks are incomplete JPEG images, because
-they lack the DHT segment required for decoding. Quoting from
-@url{http://www.digitalpreservation.gov/formats/fdd/fdd000063.shtml}:
-
-Avery Lee, writing in the rec.video.desktop newsgroup in 2001,
-commented that "MJPEG, or at least the MJPEG in AVIs having the
-MJPG fourcc, is restricted JPEG with a fixed -- and *omitted* --
-Huffman table. The JPEG must be YCbCr colorspace, it must be 4:2:2,
-and it must use basic Huffman encoding, not arithmetic or
-progressive. . . . You can indeed extract the MJPEG frames and
-decode them with a regular JPEG decoder, but you have to prepend
-the DHT segment to them, or else the decoder won't have any idea
-how to decompress the data. The exact table necessary is given in
-the OpenDML spec."
-
-This bitstream filter patches the header of frames extracted from an MJPEG
-stream (carrying the AVI1 header ID and lacking a DHT segment) to
-produce fully qualified JPEG images.
-
-@example
-ffmpeg -i mjpeg-movie.avi -c:v copy -bsf:v mjpeg2jpeg frame_%d.jpg
-exiftran -i -9 frame*.jpg
-ffmpeg -i frame_%d.jpg -c:v copy rotated.avi
-@end example
-
-@section mjpegadump
-
-Add an MJPEG A header to the bitstream, to enable decoding by
-Quicktime.
-
-@anchor{mov2textsub}
-@section mov2textsub
-
-Extract a representable text file from MOV subtitles, stripping the
-metadata header from each subtitle packet.
-
-See also the @ref{text2movsub} filter.
-
-@section mp3decomp
-
-Decompress non-standard compressed MP3 audio headers.
-
-@section mpeg2_metadata
-
-Modify metadata embedded in an MPEG-2 stream.
-
-@table @option
-@item display_aspect_ratio
-Set the display aspect ratio in the stream.
-
-The following fixed values are supported:
-@table @option
-@item 4/3
-@item 16/9
-@item 221/100
-@end table
-Any other value will result in square pixels being signalled instead
-(see H.262 section 6.3.3 and table 6-3).
-
-@item frame_rate
-Set the frame rate in the stream.  This is constructed from a table
-of known values combined with a small multiplier and divisor - if
-the supplied value is not exactly representable, the nearest
-representable value will be used instead (see H.262 section 6.3.3
-and table 6-4).
-
-@item video_format
-Set the video format in the stream (see H.262 section 6.3.6 and
-table 6-6).
-
-@item colour_primaries
-@item transfer_characteristics
-@item matrix_coefficients
-Set the colour description in the stream (see H.262 section 6.3.6
-and tables 6-7, 6-8 and 6-9).
-
-@end table
-
-@section mpeg4_unpack_bframes
-
-Unpack DivX-style packed B-frames.
-
-DivX-style packed B-frames are not valid MPEG-4 and were only a
-workaround for the broken Video for Windows subsystem.
-They use more space, can cause minor AV sync issues, require more
-CPU power to decode (unless the player has some decoded picture queue
-to compensate the 2,0,2,0 frame per packet style) and cause
-trouble if copied into a standard container like mp4 or mpeg-ps/ts,
-because MPEG-4 decoders may not be able to decode them, since they are
-not valid MPEG-4.
-
-For example to fix an AVI file containing an MPEG-4 stream with
-DivX-style packed B-frames using @command{ffmpeg}, you can use the command:
-
-@example
-ffmpeg -i INPUT.avi -codec copy -bsf:v mpeg4_unpack_bframes OUTPUT.avi
-@end example
-
-@section noise
-
-Damages the contents of packets or simply drops them without damaging the
-container. Can be used for fuzzing or testing error resilience/concealment.
-
-Parameters:
-@table @option
-@item amount

-@item dropamount
-A numeral string, whose value is related to how often packets will be dropped.
-Therefore, values below or equal to 0 are forbidden, and the lower the more
-frequent packets will be dropped, with 1 meaning every packet is dropped.
-@end table
-
-The following example applies the modification to every byte but does not drop
-any packets.
-@example
-ffmpeg -i INPUT -c copy -bsf noise[=1] output.mkv
-@end example
-
-@section null
-This bitstream filter passes the packets through unchanged.

-@chapter Demuxers
-@c man begin DEMUXERS
-
-Demuxers are configured elements in FFmpeg that can read the
-multimedia streams from a particular type of file.
-
-When you configure your FFmpeg build, all the supported demuxers
-are enabled by default. You can list all available ones using the
-configure option @code{--list-demuxers}.
-
-You can disable all the demuxers using the configure option
-@code{--disable-demuxers}, and selectively enable a single demuxer with
-the option @code{--enable-demuxer=@var{DEMUXER}}, or disable it
-with the option @code{--disable-demuxer=@var{DEMUXER}}.
-
-The option @code{-demuxers} of the ff* tools will display the list of
-enabled demuxers. Use @code{-formats} to view a combined list of
-enabled demuxers and muxers.
-
-The description of some of the currently available demuxers follows.
-
-@section aa
-
-Audible Format 2, 3, and 4 demuxer.
-
-This demuxer is used to demux Audible Format 2, 3, and 4 (.aa) files.
-
-@section apng
-
-Animated Portable Network Graphics demuxer.
-
-This demuxer is used to demux APNG files.
-All headers, but the PNG signature, up to (but not including) the first
-fcTL chunk are transmitted as extradata.
-Frames are then split as being all the chunks between two fcTL ones, or
-between the last fcTL and IEND chunks.
-
-@table @option
-@item -ignore_loop @var{bool}
-Ignore the loop variable in the file if set.
-@item -max_fps @var{int}
-Maximum framerate in frames per second (0 for no limit).
-@item -default_fps @var{int}
-Default framerate in frames per second when none is specified in the file
-(0 meaning as fast as possible).
-@end table
-
-@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 packets 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 file-related 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 -1.
-
-To make FFmpeg recognize the format automatically, this directive must
-appear 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.
-
-@item @code{inpoint @var{timestamp}}
-In point of the file. When the demuxer opens the file it instantly seeks to the
-specified timestamp. Seeking is done so that all streams can be presented
-successfully at In point.
-
-This directive works best with intra frame codecs, because for non-intra frame
-ones you will usually get extra packets before the actual In point and the
-decoded content will most likely contain frames before In point too.
-
-For each file, packets before the file In point will have timestamps less than
-the calculated start timestamp of the file (negative in case of the first
-file), and the duration of the files (if not specified by the @code{duration}
-directive) will be reduced based on their specified In point.
-
-Because of potential packets before the specified In point, packet timestamps
-may overlap between two concatenated files.
-
-@item @code{outpoint @var{timestamp}}
-Out point of the file. When the demuxer reaches the specified decoding
-timestamp in any of the streams, it handles it as an end of file condition and
-skips the current and all the remaining packets from all streams.
-
-Out point is exclusive, which means that the demuxer will not output packets
-with a decoding timestamp greater or equal to Out point.
-
-This directive works best with intra frame codecs and formats where all streams
-are tightly interleaved. For non-intra frame codecs you will usually get
-additional packets with presentation timestamp after Out point therefore the
-decoded content will most likely contain frames after Out point too. If your
-streams are not tightly interleaved you may not get all the packets from all
-streams before Out point and you may only will be able to decode the earliest
-stream until Out point.
-
-The duration of the files (if not specified by the @code{duration}
-directive) will be reduced based on their specified Out point.
-
-@item @code{file_packet_metadata @var{key=value}}
-Metadata of the packets of the file. The specified metadata will be set for
-each file packet. You can specify this directive multiple times to add multiple
-metadata entries.
-
-@item @code{stream}
-Introduce a stream in the virtual file.
-All subsequent stream-related directives apply to the last introduced
-stream.
-Some streams properties must be set in order to allow identifying the
-matching streams in the subfiles.
-If no streams are defined in the script, the streams from the first file are
-copied.
-
-@item @code{exact_stream_id @var{id}}
-Set the id of the stream.
-If this directive is given, the string with the corresponding id in the
-subfiles will be used.
-This is especially useful for MPEG-PS (VOB) files, where the order of the
-streams is not reliable.
-
-@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.
-
--1 is equivalent to 1 if the format was automatically
-probed and 0 otherwise.
-
-@item auto_convert
-If set to 1, try to perform automatic conversions on packet data to make the
-streams concatenable.
-The default is 1.
-
-Currently, the only conversion is adding the h264_mp4toannexb bitstream
-filter to H.264 streams in MP4 format. This is necessary in particular if
-there are resolution changes.
-
-@item segment_time_metadata
-If set to 1, every packet will contain the @var{lavf.concat.start_time} and the
-@var{lavf.concat.duration} packet metadata values which are the start_time and
-the duration of the respective file segments in the concatenated output
-expressed in microseconds. The duration metadata is only set if it is known
-based on the concat file.
-The default is 0.
-
-@end table
-
-@subsection Examples
-
-@itemize
-@item
-Use absolute filenames and include some comments:
-@example
-# my first filename
-file /mnt/share/file-1.wav
-# my second filename including whitespace
-file '/mnt/share/file 2.wav'
-# my third filename including whitespace plus single quote
-file '/mnt/share/file 3'\''.wav'
-@end example
-
-@item
-Allow for input format auto-probing, use safe filenames and set the duration of
-the first file:
-@example
-ffconcat version 1.0
-
-file file-1.wav
-duration 20.0
-
-file subdir/file-2.wav
-@end example
-@end itemize
-
-@section dash
-
-Dynamic Adaptive Streaming over HTTP demuxer.
-
-This demuxer presents all AVStreams found in the manifest.
-By setting the discard flags on AVStreams the caller can decide
-which streams to actually receive.
-Each stream mirrors the @code{id} and @code{bandwidth} properties from the
-@code{<Representation>} as metadata keys named "id" and "variant_bitrate" respectively.
-
-@section flv, live_flv
-
-Adobe Flash Video Format demuxer.
-
-This demuxer is used to demux FLV files and RTMP network streams. In case of live network streams, if you force format, you may use live_flv option instead of flv to survive timestamp discontinuities.
-
-@example
-ffmpeg -f flv -i myfile.flv ...
-ffmpeg -f live_flv -i rtmp://<any.server>/anything/key ....
-@end example
-
-
-@table @option
-@item -flv_metadata @var{bool}
-Allocate the streams according to the onMetaData array content.
-
-@item -flv_ignore_prevtag @var{bool}
-Ignore the size of previous tag value.
-
-@item -flv_full_metadata @var{bool}
-Output all context of the onMetadata.
-@end table
-
-@section gif
-
-Animated GIF demuxer.
-
-It accepts the following options:
-
-@table @option
-@item min_delay
-Set the minimum valid delay between frames in hundredths of seconds.
-Range is 0 to 6000. Default value is 2.
-
-@item max_gif_delay
-Set the maximum valid delay between frames in hundredth of seconds.
-Range is 0 to 65535. Default value is 65535 (nearly eleven minutes),
-the maximum value allowed by the specification.
-
-@item default_delay
-Set the default delay between frames in hundredths of seconds.
-Range is 0 to 6000. Default value is 10.
-
-@item ignore_loop
-GIF files can contain information to loop a certain number of times (or
-infinitely). If @option{ignore_loop} is set to 1, then the loop setting
-from the input will be ignored and looping will not occur. If set to 0,
-then looping will occur and will cycle the number of times according to
-the GIF. Default value is 1.
-@end table
-
-For example, with the overlay filter, place an infinitely looping GIF
-over another video:
-@example
-ffmpeg -i input.mp4 -ignore_loop 0 -i input.gif -filter_complex overlay=shortest=1 out.mkv
-@end example
-
-Note that in the above example the shortest option for overlay filter is
-used to end the output video at the length of the shortest input file,
-which in this case is @file{input.mp4} as the GIF in this example loops
-infinitely.
-
-@section hls
-
-HLS demuxer
-
-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".
-
-It accepts the following options:
-
-@table @option
-@item live_start_index
-segment index to start live streams at (negative values are from the end).
-
-@item allowed_extensions
-',' separated list of file extensions that hls is allowed to access.
-
-@item max_reload
-Maximum number of times a insufficient list is attempted to be reloaded.
-Default value is 1000.
-
-@item http_persistent
-Use persistent HTTP connections. Applicable only for HTTP streams.
-Enabled by default.
-
-@item http_multiple
-Use multiple HTTP connections for downloading HTTP segments.
-Enabled by default for HTTP/1.1 servers.
-@end table
-
-@section image2
-
-Image file demuxer.
-
-This demuxer reads from a list of image files specified by a pattern.
-The syntax and meaning of the pattern is specified by the
-option @var{pattern_type}.
-
-The pattern may contain a suffix which is used to automatically
-determine the format of the images contained in the files.
-
-The size, the pixel format, and the format of each image must be the
-same for all the files in the sequence.
-
-This demuxer accepts the following options:
-@table @option
-@item framerate
-Set the frame rate for the video stream. It defaults to 25.
-@item loop
-If set to 1, loop over the input. Default value is 0.
-@item pattern_type
-Select the pattern type used to interpret the provided filename.
-
-@var{pattern_type} accepts one of the following values.
-@table @option
-@item none
-Disable pattern matching, therefore the video will only contain the specified
-image. You should use this option if you do not want to create sequences from
-multiple images and your filenames may contain special pattern characters.
-@item sequence
-Select a sequence pattern type, used to specify a sequence of files
-indexed by sequential numbers.
-
-A sequence pattern may contain the string "%d" or "%0@var{N}d", which
-specifies the position of the characters representing a sequential
-number in each filename matched by the pattern. If the form
-"%d0@var{N}d" is used, the string representing the number in each
-filename is 0-padded and @var{N} is the total number of 0-padded
-digits representing the number. The literal character '%' can be
-specified in the pattern with the string "%%".
-
-If the sequence pattern contains "%d" or "%0@var{N}d", the first filename of
-the file list specified by the pattern must contain a number
-inclusively contained between @var{start_number} and
-@var{start_number}+@var{start_number_range}-1, and all the following
-numbers must be sequential.
-
-For example the pattern "img-%03d.bmp" will match a sequence of
-filenames of the form @file{img-001.bmp}, @file{img-002.bmp}, ...,
-@file{img-010.bmp}, etc.; the pattern "i%%m%%g-%d.jpg" will match a
-sequence of filenames of the form @file{i%m%g-1.jpg},
-@file{i%m%g-2.jpg}, ..., @file{i%m%g-10.jpg}, etc.
-
-Note that the pattern must not necessarily contain "%d" or
-"%0@var{N}d", for example to convert a single image file
-@file{img.jpeg} you can employ the command:
-@example
-ffmpeg -i img.jpeg img.png
-@end example
-
-@item glob
-Select a glob wildcard pattern type.
-
-The pattern is interpreted like a @code{glob()} pattern. This is only
-selectable if libavformat was compiled with globbing support.
-
-@item glob_sequence @emph{(deprecated, will be removed)}
-Select a mixed glob wildcard/sequence pattern.
-
-If your version of libavformat was compiled with globbing support, and
-the provided pattern contains at least one glob meta character among
-@code{%*?[]@{@}} that is preceded by an unescaped "%", the pattern is
-interpreted like a @code{glob()} pattern, otherwise it is interpreted
-like a sequence pattern.
-
-All glob special characters @code{%*?[]@{@}} must be prefixed
-with "%". To escape a literal "%" you shall use "%%".
-
-For example the pattern @code{foo-%*.jpeg} will match all the
-filenames prefixed by "foo-" and terminating with ".jpeg", and
-@code{foo-%?%?%?.jpeg} will match all the filenames prefixed with
-"foo-", followed by a sequence of three characters, and terminating
-with ".jpeg".
-
-This pattern type is deprecated in favor of @var{glob} and
-@var{sequence}.
-@end table
-
-Default value is @var{glob_sequence}.
-@item pixel_format
-Set the pixel format of the images to read. If not specified the pixel
-format is guessed from the first image file in the sequence.
-@item start_number
-Set the index of the file matched by the image file pattern to start
-to read from. Default value is 0.
-@item start_number_range
-Set the index interval range to check when looking for the first image
-file in the sequence, starting from @var{start_number}. Default value
-is 5.
-@item ts_from_file
-If set to 1, will set frame timestamp to modification time of image file. Note
-that monotonity of timestamps is not provided: images go in the same order as
-without this option. Default value is 0.
-If set to 2, will set frame timestamp to the modification time of the image file in
-nanosecond precision.
-@item video_size
-Set the video size of the images to read. If not specified the video
-size is guessed from the first image file in the sequence.
-@end table
-
-@subsection Examples
-
-@itemize
-@item
-Use @command{ffmpeg} for creating a video from the images in the file
-sequence @file{img-001.jpeg}, @file{img-002.jpeg}, ..., assuming an
-input frame rate of 10 frames per second:
-@example
-ffmpeg -framerate 10 -i 'img-%03d.jpeg' out.mkv
-@end example
-
-@item
-As above, but start by reading from a file with index 100 in the sequence:
-@example
-ffmpeg -framerate 10 -start_number 100 -i 'img-%03d.jpeg' out.mkv
-@end example
-
-@item
-Read images matching the "*.png" glob pattern , that is all the files
-terminating with the ".png" suffix:
-@example
-ffmpeg -framerate 10 -pattern_type glob -i "*.png" out.mkv

-@item enable_drefs
-Enable loading of external tracks, disabled by default.
-Enabling this can theoretically leak information in some use cases.
-
-@item use_absolute_path
-Allows loading of external tracks via absolute paths, disabled by default.
-Enabling this poses a security risk. It should only be enabled if the source
-is known to be non malicious.
-
-@end table
-
-@section mpegts
-
-MPEG-2 transport stream demuxer.
-
-This demuxer accepts the following options:
-@table @option
-@item resync_size
-Set size limit for looking up a new synchronization. Default value is
-65536.
-
-@item skip_unknown_pmt
-Skip PMTs for programs not defined in the PAT. Default value is 0.
-
-@item fix_teletext_pts
-Override teletext packet PTS and DTS values with the timestamps calculated
-from the PCR of the first program which the teletext stream is part of and is
-not discarded. Default value is 1, set this option to 0 if you want your
-teletext packet PTS and DTS values untouched.
-
-@item ts_packetsize
-Output option carrying the raw packet size in bytes.
-Show the detected raw packet size, cannot be set by the user.
-
-@item scan_all_pmts
-Scan and combine all PMTs. The value is an integer with value from -1
-to 1 (-1 means automatic setting, 1 means enabled, 0 means
-disabled). Default value is -1.
-
-@item merge_pmt_versions
-Re-use existing streams when a PMT's version is updated and elementary
-streams move to different PIDs. Default value is 0.
-@end table
-
-@section mpjpeg
-
-MJPEG encapsulated in multi-part MIME demuxer.
-
-This demuxer allows reading of MJPEG, where each frame is represented as a part of
-multipart/x-mixed-replace stream.
-@table @option
-
-@item strict_mime_boundary
-Default implementation applies a relaxed standard to multi-part MIME boundary detection,
-to prevent regression with numerous existing endpoints not generating a proper MIME
-MJPEG stream. Turning this option on by setting it to 1 will result in a stricter check
-of the boundary value.
-@end table
-
-@section rawvideo
-
-Raw video demuxer.
-
-This demuxer allows one to read raw video data. Since there is no header
-specifying the assumed video parameters, the user must specify them
-in order to be able to decode the data correctly.
-
-This demuxer accepts the following options:
-@table @option
-
-@item framerate
-Set input video frame rate. Default value is 25.
-
-@item pixel_format
-Set the input video pixel format. Default value is @code{yuv420p}.
-
-@item video_size
-Set the input video size. This value must be specified explicitly.
-@end table
-
-For example to read a rawvideo file @file{input.raw} with
-@command{ffplay}, assuming a pixel format of @code{rgb24}, a video
-size of @code{320x240}, and a frame rate of 10 images per second, use
-the command:
-@example
-ffplay -f rawvideo -pixel_format rgb24 -video_size 320x240 -framerate 10 input.raw
-@end example
-
-@section sbg
-
-SBaGen script demuxer.
-
-This demuxer reads the script language used by SBaGen
-@url{http://uazu.net/sbagen/} to generate binaural beats sessions. A SBG
-script looks like that:
-@example
--SE
-a: 300-2.5/3 440+4.5/0
-b: 300-2.5/0 440+4.5/3
-off: -
-NOW      == a
-+0:07:00 == b
-+0:14:00 == a
-+0:21:00 == b
-+0:30:00    off
-@end example
-
-A SBG script can mix absolute and relative timestamps. If the script uses
-either only absolute timestamps (including the script start time) or only
-relative ones, then its layout is fixed, and the conversion is
-straightforward. On the other hand, if the script mixes both kind of
-timestamps, then the @var{NOW} reference for relative timestamps will be
-taken from the current time of day at the time the script is read, and the
-script layout will be frozen according to that reference. That means that if
-the script is directly played, the actual times will match the absolute
-timestamps up to the sound controller's clock accuracy, but if the user
-somehow pauses the playback or seeks, all times will be shifted accordingly.
-
-@section tedcaptions
-
-JSON captions used for @url{http://www.ted.com/, TED Talks}.
-
-TED does not provide links to the captions, but they can be guessed from the
-page. The file @file{tools/bookmarklets.html} from the FFmpeg source tree
-contains a bookmarklet to expose them.
-
-This demuxer accepts the following option:
-@table @option
-@item start_time
-Set the start time of the TED talk, in milliseconds. The default is 15000
-(15s). It is used to sync the captions with the downloadable videos, because
-they include a 15s intro.
-@end table
-
-Example: convert the captions to a format most players understand:
-@example
-ffmpeg -i http://www.ted.com/talks/subtitles/id/1/lang/en talk1-en.srt
-@end example
-
-@section vapoursynth
-
-Vapoursynth wrapper.
-
-Due to security concerns, Vapoursynth scripts will not
-be autodetected so the input format has to be forced. For ff* CLI tools,
-add @code{-f vapoursynth} before the input @code{-i yourscript.vpy}.
-
-This demuxer accepts the following option:
-@table @option
-@item max_script_size
-The demuxer buffers the entire script into memory. Adjust this value to set the maximum buffer size,
-which in turn, acts as a ceiling for the size of scripts that can be read.
-Default is 1 MiB.

-@chapter Notes for external developers
-
-This document is mostly useful for internal FFmpeg developers.
-External developers who need to use the API in their application should
-refer to the API doxygen documentation in the public headers, and
-check the examples in @file{doc/examples} and in the source code to
-see how the public API is employed.
-
-You can use the FFmpeg libraries in your commercial program, but you
-are encouraged to @emph{publish any patch you make}. In this case the
-best way to proceed is to send your patches to the ffmpeg-devel
-mailing list following the guidelines illustrated in the remainder of
-this document.
-
-For more detailed legal information about the use of FFmpeg in
-external programs read the @file{LICENSE} file in the source tree and
-consult @url{https://ffmpeg.org/legal.html}.
-
-@chapter Contributing
-
-There are 2 ways by which code gets into FFmpeg:
-@itemize @bullet
-@item Submitting patches to the ffmpeg-devel mailing list.
-      See @ref{Submitting patches} for details.
-@item Directly committing changes to the main tree.
-@end itemize
-
-Whichever way, changes should be reviewed by the maintainer of the code
-before they are committed. And they should follow the @ref{Coding Rules}.
-The developer making the commit and the author are responsible for their changes
-and should try to fix issues their commit causes.
-
-@anchor{Coding Rules}
-@chapter Coding Rules
-
-@section Code formatting conventions
-
-There are the following guidelines regarding the indentation in files:
-
-@itemize @bullet
-@item
-Indent size is 4.
-
-@item
-The TAB character is forbidden outside of Makefiles as is any
-form of trailing whitespace. Commits containing either will be
-rejected by the git repository.
-
-@item
-You should try to limit your code lines to 80 characters; however, do so if
-and only if this improves readability.
-
-@item
-K&R coding style is used.
-@end itemize
-The presentation is one inspired by 'indent -i4 -kr -nut'.
-
-The main priority in FFmpeg is simplicity and small code size in order to
-minimize the bug count.
-
-@section Comments
-Use the JavaDoc/Doxygen  format (see examples below) so that code documentation
-can be generated automatically. All nontrivial functions should have a comment
-above them explaining what the function does, even if it is just one sentence.
-All structures and their member variables should be documented, too.
-
-Avoid Qt-style and similar Doxygen syntax with @code{!} in it, i.e. replace
-@code{//!} with @code{///} and similar.  Also @@ syntax should be employed
-for markup commands, i.e. use @code{@@param} and not @code{\param}.
-
-@example
-/**
- * @@file
- * MPEG codec.
- * @@author ...
- */
-
-/**
- * Summary sentence.
- * more text ...
- * ...
- */
-typedef struct Foobar @{
-    int var1; /**< var1 description */
-    int var2; ///< var2 description
-    /** var3 description */
-    int var3;
-@} Foobar;
-
-/**
- * Summary sentence.
- * more text ...
- * ...
- * @@param my_parameter description of my_parameter
- * @@return return value description
- */
-int myfunc(int my_parameter)
-...
-@end example
-
-@section C language features
-
-FFmpeg is programmed in the ISO C90 language with a few additional
-features from ISO C99, namely:
-
-@itemize @bullet
-@item
-the @samp{inline} keyword;
-
-@item
-@samp{//} comments;
-
-@item
-designated struct initializers (@samp{struct s x = @{ .i = 17 @};});
-
-@item
-compound literals (@samp{x = (struct s) @{ 17, 23 @};}).
-
-@item
-for loops with variable definition (@samp{for (int i = 0; i < 8; i++)});
-
-@item
-Implementation defined behavior for signed integers is assumed to match the
-expected behavior for two's complement. Non representable values in integer
-casts are binary truncated. Shift right of signed values uses sign extension.
-@end itemize
-
-These features are supported by all compilers we care about, so we will not
-accept patches to remove their use unless they absolutely do not impair
-clarity and performance.
-
-All code must compile with recent versions of GCC and a number of other
-currently supported compilers. To ensure compatibility, please do not use
-additional C99 features or GCC extensions. Especially watch out for:
-
-@itemize @bullet
-@item
-mixing statements and declarations;
-
-@item
-@samp{long long} (use @samp{int64_t} instead);
-
-@item
-@samp{__attribute__} not protected by @samp{#ifdef __GNUC__} or similar;
-
-@item
-GCC statement expressions (@samp{(x = (@{ int y = 4; y; @})}).
-@end itemize
-
-@section Naming conventions
-All names should be composed with underscores (_), not CamelCase. For example,
-@samp{avfilter_get_video_buffer} is an acceptable function name and
-@samp{AVFilterGetVideo} is not. The exception from this are type names, like
-for example structs and enums; they should always be in CamelCase.
-
-There are the following conventions for naming variables and functions:
-
-@itemize @bullet
-@item
-For local variables no prefix is required.
-
-@item
-For file-scope variables and functions declared as @code{static}, no prefix
-is required.
-
-@item
-For variables and functions visible outside of file scope, but only used
-internally by a library, an @code{ff_} prefix should be used,
-e.g. @samp{ff_w64_demuxer}.
-
-@item
-For variables and functions visible outside of file scope, used internally
-across multiple libraries, use @code{avpriv_} as prefix, for example,
-@samp{avpriv_report_missing_feature}.
-
-@item
-Each library has its own prefix for public symbols, in addition to the
-commonly used @code{av_} (@code{avformat_} for libavformat,
-@code{avcodec_} for libavcodec, @code{swr_} for libswresample, etc).
-Check the existing code and choose names accordingly.
-Note that some symbols without these prefixes are also exported for
-retro-compatibility reasons. These exceptions are declared in the
-@code{lib<name>/lib<name>.v} files.
-@end itemize
-
-Furthermore, name space reserved for the system should not be invaded.
-Identifiers ending in @code{_t} are reserved by
-@url{http://pubs.opengroup.org/onlinepubs/007904975/functions/xsh_chap02_02.html#tag_02_02_02, POSIX}.
-Also avoid names starting with @code{__} or @code{_} followed by an uppercase
-letter as they are reserved by the C standard. Names starting with @code{_}
-are reserved at the file level and may not be used for externally visible
-symbols. If in doubt, just avoid names starting with @code{_} altogether.
-
-@section Miscellaneous conventions
-
-@itemize @bullet
-@item
-fprintf and printf are forbidden in libavformat and libavcodec,
-please use av_log() instead.
-
-@item
-Casts should be used only when necessary. Unneeded parentheses
-should also be avoided if they don't make the code easier to understand.
-@end itemize
-
-@section Editor configuration
-In order to configure Vim to follow FFmpeg formatting conventions, paste
-the following snippet into your @file{.vimrc}:
-@example
-" indentation rules for FFmpeg: 4 spaces, no tabs
-set expandtab
-set shiftwidth=4
-set softtabstop=4
-set cindent
-set cinoptions=(0
-" Allow tabs in Makefiles.
-autocmd FileType make,automake set noexpandtab shiftwidth=8 softtabstop=8
-" Trailing whitespace and tabs are forbidden, so highlight them.
-highlight ForbiddenWhitespace ctermbg=red guibg=red
-match ForbiddenWhitespace /\s\+$\|\t/
-" Do not highlight spaces at the end of line while typing on that line.
-autocmd InsertEnter * match ForbiddenWhitespace /\t\|\s\+\%#\@@<!$/
-@end example
-
-For Emacs, add these roughly equivalent lines to your @file{.emacs.d/init.el}:
-@lisp
-(c-add-style "ffmpeg"
-             '("k&r"
-               (c-basic-offset . 4)
-               (indent-tabs-mode . nil)
-               (show-trailing-whitespace . t)
-               (c-offsets-alist
-                (statement-cont . (c-lineup-assignments +)))
-               )
-             )
-(setq c-default-style "ffmpeg")
-@end lisp

-@chapter Development Policy
-
-@section Patches/Committing
-@subheading Licenses for patches must be compatible with FFmpeg.
-Contributions should be licensed under the
-@uref{http://www.gnu.org/licenses/lgpl-2.1.html, LGPL 2.1},
-including an "or any later version" clause, or, if you prefer
-a gift-style license, the
-@uref{http://opensource.org/licenses/isc-license.txt, ISC} or
-@uref{http://mit-license.org/, MIT} license.
-@uref{http://www.gnu.org/licenses/gpl-2.0.html, GPL 2} including
-an "or any later version" clause is also acceptable, but LGPL is
-preferred.
-If you add a new file, give it a proper license header. Do not copy and
-paste it from a random place, use an existing file as template.
-
-@subheading You must not commit code which breaks FFmpeg!
-This means unfinished code which is enabled and breaks compilation,
-or compiles but does not work/breaks the regression tests. Code which
-is unfinished but disabled may be permitted under-circumstances, like
-missing samples or an implementation with a small subset of features.
-Always check the mailing list for any reviewers with issues and test
-FATE before you push.
-
-@subheading Keep the main commit message short with an extended description below.
-The commit message should have a short first line in the form of
-a @samp{topic: short description} as a header, separated by a newline
-from the body consisting of an explanation of why the change is necessary.
-If the commit fixes a known bug on the bug tracker, the commit message
-should include its bug ID. Referring to the issue on the bug tracker does
-not exempt you from writing an excerpt of the bug in the commit message.
-
-@subheading Testing must be adequate but not excessive.
-If it works for you, others, and passes FATE then it should be OK to commit
-it, provided it fits the other committing criteria. You should not worry about
-over-testing things. If your code has problems (portability, triggers
-compiler bugs, unusual environment etc) they will be reported and eventually
-fixed.
-
-@subheading Do not commit unrelated changes together.
-They should be split them into self-contained pieces. Also do not forget
-that if part B depends on part A, but A does not depend on B, then A can
-and should be committed first and separate from B. Keeping changes well
-split into self-contained parts makes reviewing and understanding them on
-the commit log mailing list easier. This also helps in case of debugging
-later on.
-Also if you have doubts about splitting or not splitting, do not hesitate to
-ask/discuss it on the developer mailing list.
-
-@subheading Ask before you change the build system (configure, etc).
-Do not commit changes to the build system (Makefiles, configure script)
-which change behavior, defaults etc, without asking first. The same
-applies to compiler warning fixes, trivial looking fixes and to code
-maintained by other developers. We usually have a reason for doing things
-the way we do. Send your changes as patches to the ffmpeg-devel mailing
-list, and if the code maintainers say OK, you may commit. This does not
-apply to files you wrote and/or maintain.
-
-@subheading Cosmetic changes should be kept in separate patches.
-We refuse source indentation and other cosmetic changes if they are mixed
-with functional changes, such commits will be rejected and removed. Every
-developer has his own indentation style, you should not change it. Of course
-if you (re)write something, you can use your own style, even though we would
-prefer if the indentation throughout FFmpeg was consistent (Many projects
-force a given indentation style - we do not.). If you really need to make
-indentation changes (try to avoid this), separate them strictly from real
-changes.
-
-NOTE: If you had to put if()@{ .. @} over a large (> 5 lines) chunk of code,
-then either do NOT change the indentation of the inner part within (do not
-move it to the right)! or do so in a separate commit
-
-@subheading Commit messages should always be filled out properly.
-Always fill out the commit log message. Describe in a few lines what you
-changed and why. You can refer to mailing list postings if you fix a
-particular bug. Comments such as "fixed!" or "Changed it." are unacceptable.
-Recommended format:
-
-@example
-area changed: Short 1 line description
-
-details describing what and why and giving references.
-@end example
-
-@subheading Credit the author of the patch.
-Make sure the author of the commit is set correctly. (see git commit --author)
-If you apply a patch, send an
-answer to ffmpeg-devel (or wherever you got the patch from) saying that
-you applied the patch.
-
-@subheading Complex patches should refer to discussion surrounding them.
-When applying patches that have been discussed (at length) on the mailing
-list, reference the thread in the log message.
-
-@subheading Always wait long enough before pushing changes
-Do NOT commit to code actively maintained by others without permission.
-Send a patch to ffmpeg-devel. If no one answers within a reasonable
-time-frame (12h for build failures and security fixes, 3 days small changes,
-1 week for big patches) then commit your patch if you think it is OK.
-Also note, the maintainer can simply ask for more time to review!
-
-@section Code
-@subheading API/ABI changes should be discussed before they are made.
-Do not change behavior of the programs (renaming options etc) or public
-API or ABI without first discussing it on the ffmpeg-devel mailing list.
-Do not remove widely used functionality or features (redundant code can be removed).
-
-@subheading Remember to check if you need to bump versions for libav*.
-Depending on the change, you may need to change the version integer.
-Incrementing the first component means no backward compatibility to
-previous versions (e.g. removal of a function from the public API).
-Incrementing the second component means backward compatible change
-(e.g. addition of a function to the public API or extension of an
-existing data structure).
-Incrementing the third component means a noteworthy binary compatible
-change (e.g. encoder bug fix that matters for the decoder). The third
-component always starts at 100 to distinguish FFmpeg from Libav.
-
-@subheading Warnings for correct code may be disabled if there is no other option.
-Compiler warnings indicate potential bugs or code with bad style. If a type of
-warning always points to correct and clean code, that warning should
-be disabled, not the code changed.
-Thus the remaining warnings can either be bugs or correct code.
-If it is a bug, the bug has to be fixed. If it is not, the code should
-be changed to not generate a warning unless that causes a slowdown
-or obfuscates the code.
-
-@subheading Check untrusted input properly.
-Never write to unallocated memory, never write over the end of arrays,
-always check values read from some untrusted source before using them
-as array index or other risky things.
-
-@section Documentation/Other
-@subheading Subscribe to the ffmpeg-devel mailing list.
-It is important to be subscribed to the
-@uref{https://lists.ffmpeg.org/mailman/listinfo/ffmpeg-devel, ffmpeg-devel}
-mailing list. Almost any non-trivial patch is to be sent there for review.
-Other developers may have comments about your contribution. We expect you see
-those comments, and to improve it if requested. (N.B. Experienced committers
-have other channels, and may sometimes skip review for trivial fixes.) Also,
-discussion here about bug fixes and FFmpeg improvements by other developers may
-be helpful information for you. Finally, by being a list subscriber, your
-contribution will be posted immediately to the list, without the moderation
-hold which messages from non-subscribers experience.
-
-However, it is more important to the project that we receive your patch than
-that you be subscribed to the ffmpeg-devel list. If you have a patch, and don't
-want to subscribe and discuss the patch, then please do send it to the list
-anyway.
-
-@subheading Subscribe to the ffmpeg-cvslog mailing list.
-Diffs of all commits are sent to the
-@uref{https://lists.ffmpeg.org/mailman/listinfo/ffmpeg-cvslog, ffmpeg-cvslog}
-mailing list. Some developers read this list to review all code base changes
-from all sources. Subscribing to this list is not mandatory.
-
-@subheading Keep the documentation up to date.
-Update the documentation if you change behavior or add features. If you are
-unsure how best to do this, send a patch to ffmpeg-devel, the documentation
-maintainer(s) will review and commit your stuff.
-
-@subheading Important discussions should be accessible to all.
-Try to keep important discussions and requests (also) on the public
-developer mailing list, so that all developers can benefit from them.
-
-@subheading Check your entries in MAINTAINERS.
-Make sure that no parts of the codebase that you maintain are missing from the
-@file{MAINTAINERS} file. If something that you want to maintain is missing add it with
-your name after it.
-If at some point you no longer want to maintain some code, then please help in
-finding a new maintainer and also don't forget to update the @file{MAINTAINERS} file.
-
-We think our rules are not too hard. If you have comments, contact us.
-
-@chapter Code of conduct
-
-Be friendly and respectful towards others and third parties.
-Treat others the way you yourself want to be treated.
-
-Be considerate. Not everyone shares the same viewpoint and priorities as you do.
-Different opinions and interpretations help the project.
-Looking at issues from a different perspective assists development.
-
-Do not assume malice for things that can be attributed to incompetence. Even if
-it is malice, it's rarely good to start with that as initial assumption.
-
-Stay friendly even if someone acts contrarily. Everyone has a bad day
-once in a while.
-If you yourself have a bad day or are angry then try to take a break and reply
-once you are calm and without anger if you have to.
-
-Try to help other team members and cooperate if you can.
-
-The goal of software development is to create technical excellence, not for any
-individual to be better and "win" against the others. Large software projects
-are only possible and successful through teamwork.
-
-If someone struggles do not put them down. Give them a helping hand
-instead and point them in the right direction.
-
-Finally, keep in mind the immortal words of Bill and Ted,
-"Be excellent to each other."
-
-@anchor{Submitting patches}
-@chapter Submitting patches
-
-First, read the @ref{Coding Rules} above if you did not yet, in particular
-the rules regarding patch submission.
-
-When you submit your patch, please use @code{git format-patch} or
-@code{git send-email}. We cannot read other diffs :-).
-
-Also please do not submit a patch which contains several unrelated changes.
-Split it into separate, self-contained pieces. This does not mean splitting
-file by file. Instead, make the patch as small as possible while still
-keeping it as a logical unit that contains an individual change, even
-if it spans multiple files. This makes reviewing your patches much easier
-for us and greatly increases your chances of getting your patch applied.
-
-Use the patcheck tool of FFmpeg to check your patch.
-The tool is located in the tools directory.
-
-Run the @ref{Regression tests} before submitting a patch in order to verify
-it does not cause unexpected problems.
-
-It also helps quite a bit if you tell us what the patch does (for example
-'replaces lrint by lrintf'), and why (for example '*BSD isn't C99 compliant
-and has no lrint()')
-
-Also please if you send several patches, send each patch as a separate mail,
-do not attach several unrelated patches to the same mail.
-
-Patches should be posted to the
-@uref{https://lists.ffmpeg.org/mailman/listinfo/ffmpeg-devel, ffmpeg-devel}
-mailing list. Use @code{git send-email} when possible since it will properly
-send patches without requiring extra care. If you cannot, then send patches
-as base64-encoded attachments, so your patch is not trashed during
-transmission. Also ensure the correct mime type is used
-(text/x-diff or text/x-patch or at least text/plain) and that only one
-patch is inline or attached per mail.
-You can check @url{https://patchwork.ffmpeg.org}, if your patch does not show up, its mime type
-likely was wrong.
-
-Your patch will be reviewed on the mailing list. You will likely be asked
-to make some changes and are expected to send in an improved version that
-incorporates the requests from the review. This process may go through
-several iterations. Once your patch is deemed good enough, some developer
-will pick it up and commit it to the official FFmpeg tree.
-
-Give us a few days to react. But if some time passes without reaction,
-send a reminder by email. Your patch should eventually be dealt with.
-

-@chapter New codecs or formats checklist
-
-@enumerate
-@item
-Did you use av_cold for codec initialization and close functions?
-
-@item
-Did you add a long_name under NULL_IF_CONFIG_SMALL to the AVCodec or
-AVInputFormat/AVOutputFormat struct?
-
-@item
-Did you bump the minor version number (and reset the micro version
-number) in @file{libavcodec/version.h} or @file{libavformat/version.h}?
-
-@item
-Did you register it in @file{allcodecs.c} or @file{allformats.c}?
-
-@item

-@chapter Patch review process
-
-All patches posted to ffmpeg-devel will be reviewed, unless they contain a
-clear note that the patch is not for the git master branch.
-Reviews and comments will be posted as replies to the patch on the
-mailing list. The patch submitter then has to take care of every comment,
-that can be by resubmitting a changed patch or by discussion. Resubmitted
-patches will themselves be reviewed like any other patch. If at some point
-a patch passes review with no comments then it is approved, that can for
-simple and small patches happen immediately while large patches will generally
-have to be changed and reviewed many times before they are approved.
-After a patch is approved it will be committed to the repository.
-
-We will review all submitted patches, but sometimes we are quite busy so
-especially for large patches this can take several weeks.
-
-If you feel that the review process is too slow and you are willing to try to
-take over maintainership of the area of code you change then just clone
-git master and maintain the area of code there. We will merge each area from
-where its best maintained.
-
-When resubmitting patches, please do not make any significant changes
-not related to the comments received during review. Such patches will
-be rejected. Instead, submit significant changes or new features as
-separate patches.
-
-Everyone is welcome to review patches. Also if you are waiting for your patch
-to be reviewed, please consider helping to review other patches, that is a great
-way to get everyone's patches reviewed sooner.
-
-@anchor{Regression tests}
-@chapter Regression tests
-
-Before submitting a patch (or committing to the repository), you should at least
-test that you did not break anything.
-
-Running 'make fate' accomplishes this, please see @url{fate.html} for details.
-
-[Of course, some patches may change the results of the regression tests. In
-this case, the reference results of the regression tests shall be modified
-accordingly].
-
-@section Adding files to the fate-suite dataset
-
-When there is no muxer or encoder available to generate test media for a
-specific test then the media has to be included in the fate-suite.
-First please make sure that the sample file is as small as possible to test the
-respective decoder or demuxer sufficiently. Large files increase network
-bandwidth and disk space requirements.
-Once you have a working fate test and fate sample, provide in the commit
-message or introductory message for the patch series that you post to
-the ffmpeg-devel mailing list, a direct link to download the sample media.
-
-@section Visualizing Test Coverage
-
-The FFmpeg build system allows visualizing the test coverage in an easy
-manner with the coverage tools @code{gcov}/@code{lcov}.  This involves
-the following steps:
-
-@enumerate
-@item
-    Configure to compile with instrumentation enabled:
-    @code{configure --toolchain=gcov}.
-
-@item
-    Run your test case, either manually or via FATE. This can be either
-    the full FATE regression suite, or any arbitrary invocation of any
-    front-end tool provided by FFmpeg, in any combination.
-
-@item
-    Run @code{make lcov} to generate coverage data in HTML format.
-
-@item
-    View @code{lcov/index.html} in your preferred HTML viewer.
-@end enumerate
-
-You can use the command @code{make lcov-reset} to reset the coverage
-measurements. You will need to rerun @code{make lcov} after running a
-new test.
-
-@section Using Valgrind
-
-The configure script provides a shortcut for using valgrind to spot bugs
-related to memory handling. Just add the option
-@code{--toolchain=valgrind-memcheck} or @code{--toolchain=valgrind-massif}
-to your configure line, and reasonable defaults will be set for running
-FATE under the supervision of either the @strong{memcheck} or the
-@strong{massif} tool of the valgrind suite.
-
-In case you need finer control over how valgrind is invoked, use the
-@code{--target-exec='valgrind <your_custom_valgrind_options>} option in
-your configure line instead.
-
-@anchor{Release process}
-@chapter Release process
-
-FFmpeg maintains a set of @strong{release branches}, which are the
-recommended deliverable for system integrators and distributors (such as
-Linux distributions, etc.). At regular times, a @strong{release
-manager} prepares, tests and publishes tarballs on the
-@url{https://ffmpeg.org} website.
-
-There are two kinds of releases:
-
-@enumerate
-@item
-@strong{Major releases} always include the latest and greatest
-features and functionality.
-
-@item
-@strong{Point releases} are cut from @strong{release} branches,
-which are named @code{release/X}, with @code{X} being the release
-version number.
-@end enumerate
-
-Note that we promise to our users that shared libraries from any FFmpeg
-release never break programs that have been @strong{compiled} against
-previous versions of @strong{the same release series} in any case!
-
-However, from time to time, we do make API changes that require adaptations
-in applications. Such changes are only allowed in (new) major releases and
-require further steps such as bumping library version numbers and/or
-adjustments to the symbol versioning file. Please discuss such changes
-on the @strong{ffmpeg-devel} mailing list in time to allow forward planning.
-
-@anchor{Criteria for Point Releases}
-@section Criteria for Point Releases
-
-Changes that match the following criteria are valid candidates for
-inclusion into a point release:
-
-@enumerate
-@item
-Fixes a security issue, preferably identified by a @strong{CVE
-number} issued by @url{http://cve.mitre.org/}.
-
-@item
-Fixes a documented bug in @url{https://trac.ffmpeg.org}.
-
-@item
-Improves the included documentation.
-
-@item
-Retains both source code and binary compatibility with previous
-point releases of the same release branch.
-@end enumerate
-
-The order for checking the rules is (1 OR 2 OR 3) AND 4.
-
-
-@section Release Checklist
-
-The release process involves the following steps:
-
-@enumerate
-@item
-Ensure that the @file{RELEASE} file contains the version number for
-the upcoming release.
-
-@item
-Add the release at @url{https://trac.ffmpeg.org/admin/ticket/versions}.
-
-@item
-Announce the intent to do a release to the mailing list.
-
-@item
-Make sure all relevant security fixes have been backported. See
-@url{https://ffmpeg.org/security.html}.
-
-@item
-Ensure that the FATE regression suite still passes in the release
-branch on at least @strong{i386} and @strong{amd64}
-(cf. @ref{Regression tests}).
-
-@item
-Prepare the release tarballs in @code{bz2} and @code{gz} formats, and
-supplementing files that contain @code{gpg} signatures
-
-@item
-Publish the tarballs at @url{https://ffmpeg.org/releases}. Create and
-push an annotated tag in the form @code{nX}, with @code{X}
-containing the version number.
-
-@item
-Propose and send a patch to the @strong{ffmpeg-devel} mailing list
-with a news entry for the website.
-
-@item
-Publish the news entry.
-
-@item
-Send an announcement to the mailing list.

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

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