Release Notes
=============
-* 0.8 "Forbidden Fruit"
+* 0.10 "Freedom" January, 2012
+
General notes
-------------
+This release is binary compatible with 0.8 and 0.9.
-This release continues the API cleanups that have begun with the
-previous release. While it is binary compatible with 0.7, many parts of
-the public API were deprecated and will be removed in the git master and
-later releases. Please consult the doc/APIchanges file to see
-intended replacements for the deprecated APIs.
-
-Furthermore, our work on the 'ffmpeg' command-line tool has resulted in
-major revisions to its interface. In order to not break existing scripts
-and applications, we have chosen to introduce a new tool called
-'avconv', and keep the traditional 'ffmpeg' frontend for end-user's
-convenience. Please see the Changelog file for details how 'avconv'
-differs from 'ffmpeg'.
-
-Additionally, this release introduces a number of new interesting codecs
-such as the Apple Prores, Flash Screen Video 2 and Windows Media Image,
-and muxers such as LATM or CELT in Ogg, among many others. Moreover, our
-H.264 decoder has been improved to decode 4:2:2 material and our libx264
-wrapper now allows to produce 4:2:2 and 4:4:4 video.
+See the Changelog file for a list of significant changes. Note, there
+are many more new features and bugfixes than whats listed there.
-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 Libav trunk repository. If you are experiencing
-issues with any formally released version of Libav, 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.
+Bugreports against FFmpeg git master or the most recent FFmpeg release are
+accepted. If you are experiencing issues with any formally released version of
+FFmpeg, please try git master to check if the issue still exists. If it does,
+make your report against the development code following the usual bug reporting
+guidelines.
API changes
* new audio encoding API which encodes from an AVFrame to an AVPacket, thus
allowing it to properly output timing information and side data.
-* rewritten AVOptions API with better built-in support for private options.
-
-* private options support for demuxers [avformat_open_input()], muxers
-[avformat_write_header()], encoders and decoders [avcodec_open2()].
-As a result, many format- or codec-specific fields and flags in AVFormatContext
-and AVCodecContext were deprecated -- notably most of CODEC_FLAG2_* and many
-CODEC_FLAG_*.
-
-* new API for custom IO interrupt callbacks.
-
-* #include cleanup in libavutil -- libavutil/avutil.h no longer includes all
-the other headers in libavutil, they must be included manually. One specific
-result is that libavutil/mathematics.h is no longer included from
-libavcodec/avcodec.h, which is a common source of errors.
-
-Please see the file doc/APIchanges for details along with
-similar programmer-centric information.
-
+Please see the git history and the file doc/APIchanges for details.
Other notable changes
are, in order of preference:
1) Try finding a way of accomplishing the same with public API.
2) If there is no corresponding public API, but you think there should be,
-post a request on the user mailing list or IRC channel.
-3) Finally if your program needs access to Libav internals for some special
-reason then the best solution is to link statically.
+post a request on the developer mailing list or IRC channel.
+3) Finally if your program needs access to FFmpeg / libavcodec / libavformat
+internals for some special reason then the best solution is to link statically.

-@c man end
-@end example
-
-@chapter Description
-@c man begin DESCRIPTION
-
-avprobe gathers information from multimedia streams and prints it in
-human- and machine-readable fashion.
-
-For example it can be used to check the format of the container used
-by a multimedia stream and the format and type of each media stream
-contained in it.
-
-If a filename is specified in input, avprobe will try to open and
-probe the file content. If the file cannot be opened or recognized as
-a multimedia file, a positive exit code is returned.
-
-avprobe may be employed both as a standalone application or in
-combination with a textual filter, which may perform more
-sophisticated processing, e.g. statistical processing or plotting.
-
-Options are used to list some of the formats supported by avprobe or
-for specifying which information to display, and for setting how
-avprobe will show it.
-
-avprobe output is designed to be easily parsable by a textual filter,
-and consists of one or more sections of the form:
-@example
-[SECTION]
-key1=val1
-...
-keyN=valN
-[/SECTION]
-@end example
-
-Metadata tags stored in the container or in the streams are recognized
-and printed in the corresponding "FORMAT" or "STREAM" section, and
-are prefixed by the string "TAG:".

+@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 Integrating libav in your program
-
-Shared libraries should be used whenever is possible in order to reduce
-the effort distributors have to pour to support programs and to ensure
-only the public api is used.
-
-You can use Libav in your commercial program, but you must abide to the
-license, LGPL or GPL depending on the specific features used, please refer
-to @uref{http://libav.org/legal.html, our legal page} for a quick checklist and to
-the following links for the exact text of each license:
-@uref{http://git.libav.org/?p=libav.git;a=blob;f=COPYING.GPLv2, GPL version 2},

-mailing list.
+@section Integrating libavcodec or libavformat in your program
+
+You can integrate all the source code of the libraries to link them
+statically to avoid any version problem. All you need is to provide a
+'config.mak' and a 'config.h' in the parent directory. See the defines
+generated by ./configure to understand what is needed.
+
+You can use libavcodec or libavformat in your commercial program, but

@subsection Code formatting conventions
-The code is written in K&R C style. That means the following:
-@itemize @bullet

-The control statements are formatted by putting space between the statement
-and parenthesis in the following way:
-@example
-for (i = 0; i < filter->input_count; i++) @{

- continue;
-case AVLINK_STARTINIT:
- av_log(filter, AV_LOG_INFO, "circular filter chain detected");
- return 0;

-Braces in function declarations are written on the new line:
-@example
-const char *avfilter_configuration(void)
-@{
- return LIBAV_CONFIGURATION;
-@}

First, read the @ref{Coding Rules} above if you did not yet, in particular
the rules regarding patch submission.

+@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.

@section How do I encode single pictures into movies?
First, rename your pictures to follow a numerical sequence.
Then you may run:
@example
- avconv -f image2 -i img%d.jpg /tmp/a.mpg
+ ffmpeg -f image2 -i img%d.jpg /tmp/a.mpg
@end example
Notice that @samp{%d} is replaced by the image number.
Then run:
@example
- avconv -f image2 -i /tmp/img%03d.jpg /tmp/a.mpg
+ ffmpeg -f image2 -i /tmp/img%03d.jpg /tmp/a.mpg
@end example
-The same logic is used for any image format that avconv reads.
+The same logic is used for any image format that ffmpeg reads.
@section How do I encode movie to single pictures?
Use:
@example
- avconv -i movie.mpg movie%d.jpg
+ ffmpeg -i movie.mpg movie%d.jpg
@end example
The @file{movie.mpg} used as input will be converted to
Applying that to the previous example:
@example
- avconv -i movie.mpg -f image2 -c:v mjpeg menu%d.jpg
+ ffmpeg -i movie.mpg -f image2 -c:v mjpeg menu%d.jpg
@end example
Beware that there is no "jpeg" codec. Use "mjpeg" instead.
Try '-f image2 test%d.jpg'.

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

+ Stopgap hack: don't crash with size-changing streams+frame threads
+
+ MPEG1 and H.264 need their own checks, otherwise they immediately
+ deallocate shared data and crash. Another check is added to get_buffer
+ to cover remaining codecs (although it may not actually do this).
+
+ This currently involves ugly code duplication, which can hopefully
+ be eventually removed. Unfortunately this is already not handled
+ well on mainline (such as in the previous commit).

+
+ Fix default value of thread_count.
+
+ Adding a flag named "threads" somehow disabled the default value
+ of the option named "threads", which allowed thread_count to be 0

+
+ Not sure why AVOption works this way.

+ 10l: pred_direct_motion fix missed several mb_type accesses

+ I have not proven this correct yet; it's not too hard with some work

+ framecrc still shows mismatches. It does fix the worst visible
+ errors, though.

+ Call draw_edges per-MB-row instead of per-frame when possible.

+
+ Fix buffer leak in VP3 by allowing update_context() with the same context.
+
+ I assumed update_context() would only be used to copy values, so skipped
+ calling it with duplicate parameters (during flush and free) for optimization.
+
+ But VP3's release_buffer call was moved from the end of decoding to the
+ end of update_context(), so flushing would skip releasing a frame and
+ eventually run out of buffers.
+
+ Unfortunately this makes update_context() much uglier in codecs that
+ already worked, because memcpy doesn't allow src and dst to be the same.

+
+ Not a complete fix as mplayer still doesn't work right with draw_horiz_band()
+ being called from decoding threads, but that doesn't crash at least.

+
+ h264: Fix decoding race condition with PAFF
+
+ A thread can release a Picture and immediately reuse the same Picture
+ for a different frame. This is fine, unless the picture released was
+ a field-picture. In that case, there may be a future thread still decoding
+ the second field of the picture, and reusing it overwrites the shared fields
+ in the Picture.
+
+ Fixed by tracking ownership of Pictures and allowing it to be reassigned
+ to the second thread's context.
+
+ Fixes conformance sample HPCAMAPALQ_BRCM_B.264.
+ vsync still fails, and therefore FATE does as well.

+
+ Don't run the last part of decode_update_context() when the last frame was dropped.
+
+ This fixes mplayer -framedrop crashing. Of course, they're still run in some cases when it wouldn't be without threads, but those are all error conditions.

+
+ Fix REBASE_PICTURE with h.264
+
+ It was possible for last_picture_ptr to point into h.ref_list
+ instead of h.s.picture, which caused a bad pointer to be set.
+ Fixes some valgrind warnings, presumably improves behavior but
+ no changes were found.

+ Forbid calling avcodec_thread_init after avcodec_open.
+
+ Although ffplay used to do this, it never worked, since codecs

+ pthread: fix failure to initialize frame fields after flush
+
+ Commit b67d7055bf ("Clear returned pictures immediately after copying
+ them.") moved some code used to (re)initialize per-thread data before
+ starting to decode a new frame. The commit changed this to be done
+ after the results of decoding the previous frame had been returned to
+ the caller. This was buggy: when decoding state is flushed some
+ decoded frames may never be returned to caller, and thus there would
+ be no reinitialization before reusing the same thread for another
+ frame after the flush. In particular, *got_picture_ptr could be
+ incorrectly set when calling avcodec_decode_video2() after seeking.
+
+ Move the initialization code back to the previous location before
+ starting to decode a frame, but leave a line setting
+ PerThreadContext->got_picture to 0 also after returning a frame and
+ add a comment explaining why it is there.

+ vp3: fix mt decode of 4:2:2 and 4:4:4 content

+ user 0m20.681s
+ sys 0m3.277s
+
+ There may be a bug related to await_reference_row() being called too many times,
+ as it's in a loop per-chroma superblock and there are 2x as many of those
+ in 4:2:2, but not 2x as many MVs.
+
+ No idea why 4 threads have less sys overhead.

+
+ Backport VP3 crash/deadlock fix from mainline r21781.
+
+ Previously, if get_buffer() failed when allocating a golden frame,
+ it would access it in a later frame without checking it first.
+ r21781 unintentionally fixed this.
+
+ This should be impossible to trigger, but some other bug in -mt
+ causes this with frequent seeking.

+
+ Fix crash on close when decoding a single-frame h264 file with 3+ threads
+
+ Problematic code path:
+ 1. sps_buffers[0] is allocated in the first thread's codec context when the
+ decoder is opened.
+ 2. The first thread context is memcpy'd to the other threads by frame_thread_init().
+ 3. The first thread is closed and its sps_buffers[0] is freed.
+ 4. The third thread is closed.
+ Because it never got to decode a frame, update_thread_context was never called,
+ and sps_buffers[0] still contained the first thread's pointer.
+
+ Fixed by not trying to free sps/pps buffers if the thread wasn't initialized.
+ I didn't properly consider this when designing it but this seems to be the
+ best approach anyway.
+
+ Fixes still2.mp4 crash from Chromium

+
+ Remove unnecessary parameter from ff_thread_init() and fix behavior
+
+ thread_count passed to ff_thread_init() is only used to set AVCodecContext.
+ thread_count, and can be removed. Instead move it to the legacy implementation
+ of avcodec_thread_init().
+
+ This also fixes the problem that calling avcodec_thread_init() with pthreads
+ enabled did not set it since ff1efc524cb3c60f2f746e3b4550bb1a86c65316.

@chapter Stream selection
@c man begin STREAM SELECTION
-By default avconv tries to pick the "best" stream of each type present in input
-files and add them to each output file. For video, this means the highest
-resolution, for audio the highest channel count. For subtitle it's simply the
-first subtitle stream.
+By default ffmpeg includes only one stream of each type (video, audio, subtitle)
+present in the input files and adds them to each output file. It picks the
+"best" of each based upon the following criteria; for video it is the stream
+with the highest resolution, for audio the stream with the most channels, for
+subtitle it's the first subtitle stream. In the case where several streams of
+the same type rate equally, the lowest numbered stream is chosen.
You can disable some of those defaults by using @code{-vn/-an/-sn} options. For
full manual control, use the @code{-map} option, which disables the defaults just
@table @option
@item -f @var{fmt} (@emph{input/output})
-Force input or output file format. The format is normally autodetected for input
+Force input or output file format. The format is normally auto detected for input
files and guessed from file extension for output files, so this option is not
needed in most cases.
@item -y (@emph{global})
Overwrite output files without asking.
+@item -n (@emph{global})
+Do not overwrite output files but exit if file exists.
+
@item -c[:@var{stream_specifier}] @var{codec} (@emph{input/output,per-stream})
@itemx -codec[:@var{stream_specifier}] @var{codec} (@emph{input/output,per-stream})
Select an encoder (when used before an output file) or a decoder (when used
before an input file) for one or more streams. @var{codec} is the name of a
decoder/encoder or a special value @code{copy} (output only) to indicate that
-the stream is not to be reencoded.
+the stream is not to be re-encoded.
For example
@example
-avconv -i INPUT -map 0 -c:v libx264 -c:a copy OUTPUT
+ffmpeg -i INPUT -map 0 -c:v libx264 -c:a copy OUTPUT
@end example
encodes all video streams with libx264 and copies all audio streams.
For each stream, the last matching @code{c} option is applied, so
@example
-avconv -i INPUT -map 0 -c copy -c:v:1 libx264 -c:a:137 libvorbis OUTPUT
+ffmpeg -i INPUT -map 0 -c copy -c:v:1 libx264 -c:a:137 libvorbis OUTPUT
@end example
will copy all the streams except the second video, which will be encoded with
libx264, and the 138th audio, which will be encoded with libvorbis.
@var{duration} may be a number in seconds, or in @code{hh:mm:ss[.xxx]} form.
@item -fs @var{limit_size} (@emph{output})
-Set the file size limit.
+Set the file size limit, expressed in bytes.
@item -ss @var{position} (@emph{input/output})
When used as an input option (before @code{-i}), seeks in this input file to
Specifying a positive offset means that the corresponding
streams are delayed by @var{offset} seconds.
+@item -timestamp @var{time} (@emph{output})
+Set the recording timestamp in the container.
+The syntax for @var{time} is:
+@example
+now|([(YYYY-MM-DD|YYYYMMDD)[T|t| ]]((HH[:MM[:SS[.m...]]])|(HH[MM[SS[.m...]]]))[Z|z])
+@end example
+If the value is "now" it takes the current time.
+Time is local time unless 'Z' or 'z' is appended, in which case it is
+interpreted as UTC.
+If the year-month-day part is not specified it takes the current
+year-month-day.
+
@item -metadata[:metadata_specifier] @var{key}=@var{value} (@emph{output,per-metadata})
Set a metadata key/value pair.
For example, for setting the title in the output file:
@example
-avconv -i in.avi -metadata title="my title" out.flv
+ffmpeg -i in.avi -metadata title="my title" out.flv
@end example
To set the language of the first audio stream:
@example
-avconv -i INPUT -metadata:s:a:0 language=eng OUTPUT
+ffmpeg -i INPUT -metadata:s:a:1 language=eng OUTPUT
@end example
@item -target @var{type} (@emph{output})
(bitrate, codecs, buffer sizes) are then set automatically. You can just type:
@example
-avconv -i myfile.avi -target vcd /tmp/vcd.mpg
+ffmpeg -i myfile.avi -target vcd /tmp/vcd.mpg
@end example
Nevertheless you can specify additional options as long as you know
they do not conflict with the standard, as in:
@example
-avconv -i myfile.avi -target vcd -bf 2 /tmp/vcd.mpg
+ffmpeg -i myfile.avi -target vcd -bf 2 /tmp/vcd.mpg
@end example
@item -dframes @var{number} (@emph{output})
@item -stats (@emph{global})
Print encoding progress/statistics. On by default.
+@item -debug_ts (@emph{global})
+Print timestamp information. It is off by default. This option is
+mostly useful for testing and debugging purposes, and the output
+format may change from one version to another, so it should not be
+employed by portable scripts.
+
+See also the option @code{-fdebug ts}.
+
@item -attach @var{filename} (@emph{output})
Add an attachment to the output file. This is supported by a few formats
like Matroska for e.g. fonts used in rendering subtitles. Attachments
Note that for Matroska you also have to set the mimetype metadata tag:
@example
-avconv -i INPUT -attach DejaVuSans.ttf -metadata:s:2 mimetype=application/x-truetype-font out.mkv
+ffmpeg -i INPUT -attach DejaVuSans.ttf -metadata:s:2 mimetype=application/x-truetype-font out.mkv
@end example
(assuming that the attachment stream will be third in the output file).
E.g. to extract the first attachment to a file named 'out.ttf':
@example
-avconv -dump_attachment:t:0 out.ttf INPUT
+ffmpeg -dump_attachment:t:0 out.ttf INPUT
@end example
To extract all attachments to files determined by the @code{filename} tag:
@example
-avconv -dump_attachment:t "" INPUT
+ffmpeg -dump_attachment:t "" INPUT
@end example
Technical note -- attachments are implemented as codec extradata, so this
numerator and denominator of the aspect ratio. For example "4:3",
"16:9", "1.3333", and "1.7777" are valid argument values.

@section Audio/Video grab options
For example, to map ALL streams from the first input file to output
@example
-avconv -i INPUT -map 0 output
+ffmpeg -i INPUT -map 0 output
@end example
For example, if you have two audio streams in the first input file,
@code{-map} to select which streams to place in an output file. For
example:
@example
-avconv -i INPUT -map 0:1 out.wav
+ffmpeg -i INPUT -map 0:1 out.wav
@end example
will map the input stream in @file{INPUT} identified by "0:1" to
the (single) output stream in @file{out.wav}.
index 6 from input @file{b.mov} (specified by the identifier "1:6"),
and copy them to the output file @file{out.mov}:
@example
-avconv -i a.mov -i b.mov -c copy -map 0:2 -map 1:6 out.mov
+ffmpeg -i a.mov -i b.mov -c copy -map 0:2 -map 1:6 out.mov
@end example
To select all video and the third audio stream from an input file:
@example
-avconv -i INPUT -map 0:v -map 0:a:2 OUTPUT
+ffmpeg -i INPUT -map 0:v -map 0:a:2 OUTPUT
@end example
To map all the streams except the second audio, use negative mappings
@example
-avconv -i INPUT -map 0 -map -0:a:1 OUTPUT
+ffmpeg -i INPUT -map 0 -map -0:a:1 OUTPUT
@end example
Note that using this option disables the default mappings for this output file.
+@item -map_channel [@var{input_file_id}.@var{stream_specifier}.@var{channel_id}|-1][:@var{output_file_id}.@var{stream_specifier}]
+Map an audio channel from a given input to an output. If
+@var{output_file_id}.@var{stream_specifier} is not set, the audio channel will
+be mapped on all the audio streams.
+
+Using "-1" instead of
+@var{input_file_id}.@var{stream_specifier}.@var{channel_id} will map a muted
+channel.
+
+For example, assuming @var{INPUT} is a stereo audio file, you can switch the
+two audio channels with the following command:
+@example
+ffmpeg -i INPUT -map_channel 0.0.1 -map_channel 0.0.0 OUTPUT
+@end example
+
+If you want to mute the first channel and keep the second:
+@example
+ffmpeg -i INPUT -map_channel -1 -map_channel 0.0.1 OUTPUT
+@end example
+
+The order of the "-map_channel" option specifies the order of the channels in
+the output stream. The output channel layout is guessed from the number of
+channels mapped (mono if one "-map_channel", stereo if two, etc.). Using "-ac"
+in combination of "-map_channel" makes the channel gain levels to be updated if
+input and output channel layouts don't match (for instance two "-map_channel"
+options and "-ac 6").
+
+You can also extract each channel of an input to specific outputs; the following
+command extracts two channels of the @var{INPUT} audio stream (file 0, stream 0)
+to the respective @var{OUTPUT_CH0} and @var{OUTPUT_CH1} outputs:
+@example
+ffmpeg -i INPUT -map_channel 0.0.0 OUTPUT_CH0 -map_channel 0.0.1 OUTPUT_CH1
+@end example
+
+The following example splits the channels of a stereo input into two separate
+streams, which are put into the same output file:
+@example
+ffmpeg -i stereo.wav -map 0:0 -map 0:0 -map_channel 0.0.0:0.0 -map_channel 0.0.1:0.1 -y out.ogg
+@end example
+
+Note that currently each output stream can only contain channels from a single
+input stream; you can't for example use "-map_channel" to pick multiple input
+audio channels contained in different streams (from the same or different files)
+and merge them into a single output stream. It is therefore not currently
+possible, for example, to turn two separate mono streams into a single stereo
+stream. However splitting a stereo stream into two single channel mono streams
+is possible.
+
+If you need this feature, a possible workaround is to use the @emph{amerge}
+filter. For example, if you need to merge a media (here @file{input.mkv}) with 2
+mono audio streams into one single stereo channel audio stream (and keep the
+video stream), you can use the following command:
+@example
+ffmpeg -i input.mkv -f lavfi -i "
+amovie=input.mkv:si=1 [a1];
+amovie=input.mkv:si=2 [a2];
+[a1][a2] amerge" -c:a pcm_s16le -c:v copy output.mkv
+@end example
+
@item -map_metadata[:@var{metadata_spec_out}] @var{infile}[:@var{metadata_spec_in}] (@emph{output,per-metadata})
Set metadata information of the next output file from @var{infile}. Note that
those are file indices (zero-based), not filenames.
For example to copy metadata from the first stream of the input file to global metadata
of the output file:
@example
-avconv -i in.ogg -map_metadata 0:s:0 out.mp3
+ffmpeg -i in.ogg -map_metadata 0:s:0 out.mp3
@end example
To do the reverse, i.e. copy global metadata to all audio streams:
@example
-avconv -i in.mkv -map_metadata:s:a 0:g out.mkv
+ffmpeg -i in.mkv -map_metadata:s:a 0:g out.mkv
@end example
Note that simple @code{0} would work as well in this example, since global
metadata is assumed by default.

the first input file with at least one chapter. Use a negative file index to
disable any chapter copying.

+ffmpeg -i infile -streamid 0:33 -streamid 1:36 out.ts
@end example
@item -bsf[:@var{stream_specifier}] @var{bitstream_filters} (@emph{output,per-stream})
a comma-separated list of bitstream filters. Use the @code{-bsfs} option
to get the list of bitstream filters.
@example
-avconv -i h264.mp4 -c:v copy -bsf:v h264_mp4toannexb -an out.h264
+ffmpeg -i h264.mp4 -c:v copy -bsf:v h264_mp4toannexb -an out.h264
@end example
@example

+ffmpeg -i file.mov -an -vn -bsf:s mov2textsub -c:s copy -f rawvideo sub.txt
@end example
-@item -tag[:@var{stream_specifier}] @var{codec_tag} (@emph{output,per-stream})
+@item -tag[:@var{stream_specifier}] @var{codec_tag} (@emph{per-stream})

-@item -cpuflags mask (@emph{global})
-Set a mask that's applied to autodetected CPU flags. This option is intended
-for testing. Do not use it unless you know what you're doing.
+@item -timecode @var{hh}:@var{mm}:@var{ss}SEP@var{ff}
+Specify Timecode for writing. @var{SEP} is ':' for non drop timecode and ';'
+(or '.') for drop.
+@example
+ffmpeg -i input.mpg -timecode 01:02:03.04 -r 30000/1001 -s ntsc output.mpg
+@end example
@item -filter_complex @var{filtergraph} (@emph{global})

For example, to overlay an image over video
@example
-avconv -i video.mkv -i image.png -filter_complex '[0:v][1:v]overlay[out]' -map
+ffmpeg -i video.mkv -i image.png -filter_complex '[0:v][1:v]overlay[out]' -map
'[out]' out.mkv
@end example
Here @code{[0:v]} refers to the first video stream in the first input file,
Assuming there is only one video stream in each input file, we can omit input
labels, so the above is equivalent to
@example
-avconv -i video.mkv -i image.png -filter_complex 'overlay[out]' -map
+ffmpeg -i video.mkv -i image.png -filter_complex 'overlay[out]' -map
'[out]' out.mkv
@end example
Furthermore we can omit the output label and the single output from the filter
graph will be added to the output file automatically, so we can simply write
@example
-avconv -i video.mkv -i image.png -filter_complex 'overlay' out.mkv
+ffmpeg -i video.mkv -i image.png -filter_complex 'overlay' out.mkv
@end example
@end table
+
+@section Preset files
+A preset file contains a sequence of @var{option}=@var{value} pairs,
+one for each line, specifying a sequence of options which would be
+awkward to specify on the command line. Lines starting with the hash
+('#') character are ignored and are used to provide comments. Check
+the @file{presets} directory in the FFmpeg source tree for examples.
+
+Preset files are specified with the @code{vpre}, @code{apre},
+@code{spre}, and @code{fpre} options. The @code{fpre} option takes the
+filename of the preset instead of a preset name as input and can be
+used for any kind of codec. For the @code{vpre}, @code{apre}, and
+@code{spre} options, the options specified in a preset file are
+applied to the currently selected codec of the same type as the preset
+option.
+
+The argument passed to the @code{vpre}, @code{apre}, and @code{spre}
+preset options identifies the preset file to use according to the
+following rules:
+
+First ffmpeg searches for a file named @var{arg}.ffpreset in the
+directories @file{$FFMPEG_DATADIR} (if set), and @file{$HOME/.ffmpeg}, and in
+the datadir defined at configuration time (usually @file{PREFIX/share/ffmpeg})
+or in a @file{ffpresets} folder along the executable on win32,
+in that order. For example, if the argument is @code{libx264-max}, it will
+search for the file @file{libx264-max.ffpreset}.
+
+If no such file is found, then ffmpeg will search for a file named
+@var{codec_name}-@var{arg}.ffpreset in the above-mentioned
+directories, where @var{codec_name} is the name of the codec to which
+the preset file options will be applied. For example, if you select
+the video codec with @code{-vcodec libx264} and use @code{-vpre max},
+then it will search for the file @file{libx264-max.ffpreset}.

@section Video and Audio file format conversion
-Any supported file format and protocol can serve as input to avconv:
+Any supported file format and protocol can serve as input to ffmpeg:
Examples:
@itemize
You can use YUV files as input:
@example
-avconv -i /tmp/test%d.Y /tmp/out.mpg
+ffmpeg -i /tmp/test%d.Y /tmp/out.mpg
@end example
It will use the files:
The Y files use twice the resolution of the U and V files. They are
raw files, without header. They can be generated by all decent video
decoders. You must specify the size of the image with the @option{-s} option
-if avconv cannot guess it.
+if ffmpeg cannot guess it.
@item
You can input from a raw YUV420P file:
@example
-avconv -i /tmp/test.yuv /tmp/out.avi
+ffmpeg -i /tmp/test.yuv /tmp/out.avi
@end example
test.yuv is a file containing raw YUV planar data. Each frame is composed
You can output to a raw YUV420P file:
@example
-avconv -i mydivx.avi hugefile.yuv
+ffmpeg -i mydivx.avi hugefile.yuv
@end example
@item
You can set several input files and output files:
@example
-avconv -i /tmp/a.wav -s 640x480 -i /tmp/a.yuv /tmp/a.mpg
+ffmpeg -i /tmp/a.wav -s 640x480 -i /tmp/a.yuv /tmp/a.mpg
@end example
Converts the audio file a.wav and the raw YUV video file a.yuv
You can also do audio and video conversions at the same time:
@example
-avconv -i /tmp/a.wav -ar 22050 /tmp/a.mp2
+ffmpeg -i /tmp/a.wav -ar 22050 /tmp/a.mp2
@end example
Converts a.wav to MPEG audio at 22050 Hz sample rate.
mapping from input stream to output streams:
@example
-avconv -i /tmp/a.wav -map 0:a -b 64k /tmp/a.mp2 -map 0:a -b 128k /tmp/b.mp2
+ffmpeg -i /tmp/a.wav -map 0:a -b:a 64k /tmp/a.mp2 -map 0:a -b:a 128k /tmp/b.mp2
@end example
Converts a.wav to a.mp2 at 64 kbits and to b.mp2 at 128 kbits. '-map
You can transcode decrypted VOBs:
@example
-avconv -i snatch_1.vob -f avi -c:v mpeg4 -b:v 800k -g 300 -bf 2 -c:a libmp3lame -b:a 128k snatch.avi
+ffmpeg -i snatch_1.vob -f avi -c:v mpeg4 -b:v 800k -g 300 -bf 2 -c:a libmp3lame -b:a 128k snatch.avi
@end example
This is a typical DVD ripping example; the input is a VOB file, the
The mapping is particularly useful for DVD transcoding
to get the desired audio language.

You can extract images from a video, or create a video from many images:
For extracting images from a video:
@example
-avconv -i foo.avi -r 1 -s WxH -f image2 foo-%03d.jpeg
+ffmpeg -i foo.avi -r 1 -s WxH -f image2 foo-%03d.jpeg
@end example
This will extract one video frame per second from the video and will
For creating a video from many images:
@example
-avconv -f image2 -i foo-%03d.jpeg -r 12 -s WxH foo.avi
+ffmpeg -f image2 -i foo-%03d.jpeg -r 12 -s WxH foo.avi
@end example
The syntax @code{foo-%03d.jpeg} specifies to use a decimal number
number. It is the same syntax supported by the C printf function, but
only formats accepting a normal integer are suitable.
+When importing an image sequence, -i also supports expanding shell-like
+wildcard patterns (globbing) internally. To lower the chance of interfering
+with your actual file names and the shell's glob expansion, you are required
+to activate glob meta characters by prefixing them with a single @code{%}
+character, like in @code{foo-%*.jpeg}, @code{foo-%?%?%?.jpeg} or
+@code{foo-00%[234%]%*.jpeg}.
+If your filename actually contains a character sequence of a @code{%} character
+followed by a glob character, you must double the @code{%} character to escape
+it. Imagine your files begin with @code{%?-foo-}, then you could use a glob
+pattern like @code{%%?-foo-%*.jpeg}. For input patterns that could be both a
+printf or a glob pattern, ffmpeg will assume it is a glob pattern.
+
@item
You can put many streams of the same type in the output:
@example
-avconv -i test1.avi -i test2.avi -map 0.3 -map 0.2 -map 0.1 -map 0.0 -c copy test12.nut
+ffmpeg -i test1.avi -i test2.avi -map 0.3 -map 0.2 -map 0.1 -map 0.0 -c copy test12.nut
@end example
The resulting output file @file{test12.avi} will contain first four streams from
@item
To force CBR video output:
@example
-avconv -i myfile.avi -b 4000k -minrate 4000k -maxrate 4000k -bufsize 1835k out.m2v
+ffmpeg -i myfile.avi -b 4000k -minrate 4000k -maxrate 4000k -bufsize 1835k out.m2v
@end example
@item
The four options lmin, lmax, mblmin and mblmax use 'lambda' units,
but you may use the QP2LAMBDA constant to easily convert from 'q' units:
@example
-avconv -i src.ext -lmax 21*QP2LAMBDA dst.ext
+ffmpeg -i src.ext -lmax 21*QP2LAMBDA dst.ext

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

+
+A writer defines the output format adopted by @command{ffprobe}, and will be
+used for printing all the parts of the output.
+
+A writer may accept one or more arguments, which specify the options to
+adopt.
+
+A description of the currently available writers follows.
+
+@section default
+Default format.
+
+Print each section in the form:
+@example
+[SECTION]
+key1=val1
+...
+keyN=valN
+[/SECTION]
+@end example
+
+Metadata tags are printed as a line in the corresponding FORMAT or
+STREAM section, and are prefixed by the string "TAG:".
+
+@section compact
+Compact format.
+
+Each section is printed on a single line.
+If no option is specifid, the output has the form:
+@example
+section|key1=val1| ... |keyN=valN
+@end example
+
+Metadata tags are printed in the corresponding "format" or "stream"
+section. A metadata tag key, if printed, is prefixed by the string
+"tag:".
+
+This writer accepts options as a list of @var{key}=@var{value} pairs,
+separated by ":".
+
+The description of the accepted options follows.
+
+@table @option
+
+@item item_sep, s
+Specify the character to use for separating fields in the output line.
+It must be a single printable character, it is "|" by default.
+
+@item nokey, nk
+If set to 1 specify not to print the key of each field. Its default
+value is 0.
+
+@item escape, e
+Set the escape mode to use, default to "c".
+
+It can assume one of the following values:
+@table @option
+@item c
+Perform C-like escaping. Strings containing a newline ('\n') or
+carriage return ('\r'), the escaping character ('\') or the item
+separator character @var{SEP} are escaped using C-like fashioned
+escaping, so that a newline is converted to the sequence "\n", a
+carriage return to "\r", '\' to "\\" and the separator @var{SEP} is
+converted to "\@var{SEP}".
+
+@item csv
+Perform CSV-like escaping, as described in RFC4180. Strings
+containing a newline ('\n'), a carriage return ('\r'), a double quote
+('"'), or @var{SEP} are enclosed in double-quotes.
+
+@item none
+Perform no escaping.
+@end table
+
+@end table
+
+@section csv
+CSV format.
+
+This writer is equivalent to
+@code{compact=item_sep=,:nokey=1:escape=csv}.
+
+@section json
+JSON based format.
+
+Each section is printed using JSON notation.
+
+This writer accepts options as a list of @var{key}=@var{value} pairs,
+separated by ":".
+
+The description of the accepted options follows.

+If set to 1 enable compact output, that is each section will be
+printed on a single line. Default value is 0.
+@end table
+
+For more information about JSON, see @url{http://www.json.org/}.
+
+@section xml
+XML based format.
+
+The XML output is described in the XML schema description file
+@file{ffprobe.xsd} installed in the FFmpeg datadir.
+
+Note that the output issued will be compliant to the
+@file{ffprobe.xsd} schema only when no special global output options
+(@option{unit}, @option{prefix}, @option{byte_binary_prefix},
+@option{sexagesimal} etc.) are specified.
+
+This writer accepts options as a list of @var{key}=@var{value} pairs,
+separated by ":".
+
+The description of the accepted options follows.
+
+@table @option
+
+@item fully_qualified, q
+If set to 1 specify if the output should be fully qualified. Default
+value is 0.
+This is required for generating an XML file which can be validated
+through an XSD file.
+
+@item xsd_compliant, x
+If set to 1 perform more checks for ensuring that the output is XSD
+compliant. Default value is 0.
+This option automatically sets @option{fully_qualified} to 1.

-the avconv output to see if a line referring to MP3 is present. If not, then
+the ffmpeg output to see if a line referring to MP3 is present. If not, then
your configuration was incorrect. If it is, then maybe your wiring is not
set up correctly. Maybe the sound card is not getting data from the right
input source. Maybe you have a really awful audio interface (like I do)
that only captures in stereo and also requires that one channel be flipped.
If you are one of these people, then export 'AUDIO_FLIP_LEFT=1' before
-starting avconv.
+starting ffmpeg.
@subsection The audio and video lose sync after a while.
You can replay video from .ffm files that was recorded earlier.
However, there are a number of caveats, including the fact that the
-avserver parameters must match the original parameters used to record the
-file. If they do not, then avserver deletes the file before recording into it.
+ffserver parameters must match the original parameters used to record the
+file. If they do not, then ffserver deletes the file before recording into it.
(Now that I write this, it seems broken).
You can fiddle with many of the codec choices and encoding parameters, and
there are a bunch more parameters that you cannot control. Post a message
to the mailing list if there are some 'must have' parameters. Look in
-avserver.conf for a list of the currently available controls.

It will automatically generate the ASX or RAM files that are often used
in browsers. These files are actually redirections to the underlying ASF

buffer a certain number of seconds of material so that they can display the
-signal continuously. However, avserver (by default) starts sending data
+signal continuously. However, ffserver (by default) starts sending data
in realtime. This means that there is a pause of a few seconds while the
buffering is being done by the player. The good news is that this can be
cured by adding a '?buffer=5' to the end of the URL. This means that the
of the stream are sent as fast as the network will allow. It will then
slow down to real time. This noticeably improves the startup experience.

+
+Convert the input audio format to the specified formats.
+
+The filter accepts a string of the form:
+"@var{sample_format}:@var{channel_layout}".
+
+@var{sample_format} specifies the sample format, and can be a string or the
+corresponding numeric value defined in @file{libavutil/samplefmt.h}. Use 'p'

+
+@section aformat
+
+Convert the input audio to one of the specified formats. The framework will
+negotiate the most appropriate format to minimize conversions.

+The special parameter "all", in place of a list of elements, signifies all
+supported formats.
+
+Some examples follow:
+@example
+aformat=u8\\,s16:mono:packed
+
+aformat=s16:mono\\,stereo:all
+@end example
+
+@section amerge
+
+Merge two audio streams into a single multi-channel stream.
+
+This filter does not need any argument.
+
+If the channel layouts of the inputs are disjoint, and therefore compatible,
+the channel layout of the output will be set accordingly and the channels
+will be reordered as necessary. If the channel layouts of the inputs are not
+disjoint, the output will have all the channels of the first input then all
+the channels of the second input, in that order, and the channel layout of
+the output will be the default value corresponding to the total number of
+channels.
+
+For example, if the first input is in 2.1 (FL+FR+LF) and the second input
+is FC+BL+BR, then the output will be in 5.1, with the channels in the
+following order: a1, a2, b1, a3, b2, b3 (a1 is the first channel of the
+first input, b1 is the first channel of the second input).
+
+On the other hand, if both input are in stereo, the output channels will be
+in the default order: a1, a2, b1, b2, and the channel layout will be
+arbitrarily set to 4.0, which may or may not be the expected value.
+
+Both inputs must have the same sample rate, format and packing.
+
+If inputs do not have the same duration, the output will stop with the
+shortest.
+
+Example: merge two mono files into a stereo stream:
+@example
+amovie=left.wav [l] ; amovie=right.mp3 [r] ; [l] [r] amerge
+@end example
+
+If you need to do multiple merges (for instance multiple mono audio streams in
+a single video media), you can do:
+@example
+ffmpeg -f lavfi -i "
+amovie=input.mkv:si=0 [a0];
+amovie=input.mkv:si=1 [a1];
+amovie=input.mkv:si=2 [a2];
+amovie=input.mkv:si=3 [a3];
+amovie=input.mkv:si=4 [a4];
+amovie=input.mkv:si=5 [a5];
+[a0][a1] amerge [x0];
+[x0][a2] amerge [x1];
+[x1][a3] amerge [x2];
+[x2][a4] amerge [x3];
+[x3][a5] amerge" -c:a pcm_s16le output.mkv
+@end example
+
@section anull
Pass the audio source unchanged to the output.
+@section aresample
+
+Resample the input audio to the specified sample rate.
+
+The filter accepts exactly one parameter, the output sample rate. If not
+specified then the filter will automatically convert between its input
+and output sample rates.
+
+For example, to resample the input audio to 44100Hz:
+@example
+aresample=44100
+@end example
+
+@section ashowinfo
+
+Show a line containing various information for each input audio frame.
+The input audio is not modified.
+
+The shown line contains a sequence of key/value pairs of the form
+@var{key}:@var{value}.
+
+A description of each shown parameter follows:
+
+@table @option
+@item n
+sequential number of the input frame, starting from 0
+
+@item pts
+presentation TimeStamp of the input frame, expressed as a number of
+time base units. The time base unit depends on the filter input pad, and
+is usually 1/@var{sample_rate}.
+
+@item pts_time
+presentation TimeStamp of the input frame, expressed as a number of
+seconds
+
+@item pos
+position of the frame in the input stream, -1 if this information in
+unavailable and/or meaningless (for example in case of synthetic audio)
+
+@item fmt
+sample format name
+
+@item chlayout
+channel layout description
+
+@item nb_samples
+number of samples (per each channel) contained in the filtered frame
+
+@item rate
+sample rate for the audio frame
+
+@item planar
+if the packing format is planar, 0 if packed
+
+@item checksum
+Adler-32 checksum (printed in hexadecimal) of all the planes of the input frame
+
+@item plane_checksum
+Adler-32 checksum (printed in hexadecimal) for each input frame plane,
+expressed in the form "[@var{c0} @var{c1} @var{c2} @var{c3} @var{c4} @var{c5}
+@var{c6} @var{c7}]"
+@end table
+
+@section asplit
+
+Pass on the input audio to two outputs. Both outputs are identical to
+the input audio.
+
+For example:
+@example
+[in] asplit[out0], showaudio[out1]
+@end example
+
+will create two separate outputs from the same input, one cropped and
+one padded.
+
+@section astreamsync
+
+Forward two audio streams and control the order the buffers are forwarded.
+
+The argument to the filter is an expression deciding which stream should be
+forwarded next: if the result is negative, the first stream is forwarded; if
+the result is positive or zero, the second stream is forwarded. It can use
+the following variables:
+
+@table @var
+@item b1 b2
+number of buffers forwarded so far on each stream
+@item s1 s2
+number of samples forwarded so far on each stream
+@item t1 t2
+current timestamp of each stream
+@end table
+
+The default value is @code{t1-t2}, which means to always forward the stream
+that has a smaller timestamp.
+
+Example: stress-test @code{amerge} by randomly sending buffers on the wrong
+input, while avoiding too much of a desynchronization:
+@example
+amovie=file.ogg [a] ; amovie=file.mp3 [b] ;
+[a] [b] astreamsync=(2*random(1))-1+tanh(5*(t1-t2)) [a2] [b2] ;
+[a2] [b2] amerge
+@end example
+
+@section earwax
+
+Make audio easier to listen to on headphones.
+
+This filter adds `cues' to 44.1kHz stereo (i.e. audio CD format) audio
+so that when listened to on headphones the stereo image is moved from
+inside your head (standard for headphones) to outside and in front of
+the listener (standard for speakers).
+
+Ported from SoX.
+
+@section pan
+
+Mix channels with specific gain levels. The filter accepts the output
+channel layout followed by a set of channels definitions.
+
+This filter is also designed to remap efficiently the channels of an audio
+stream.
+
+The filter accepts parameters of the form:
+"@var{l}:@var{outdef}:@var{outdef}:..."
+
+@table @option
+@item l
+output channel layout or number of channels
+
+@item outdef
+output channel specification, of the form:
+"@var{out_name}=[@var{gain}*]@var{in_name}[+[@var{gain}*]@var{in_name}...]"
+
+@item out_name
+output channel to define, either a channel name (FL, FR, etc.) or a channel
+number (c0, c1, etc.)
+
+@item gain
+multiplicative coefficient for the channel, 1 leaving the volume unchanged
+
+@item in_name
+input channel to use, see out_name for details; it is not possible to mix
+named and numbered input channels
+@end table
+
+If the `=' in a channel specification is replaced by `<', then the gains for
+that specification will be renormalized so that the total is 1, thus
+avoiding clipping noise.
+
+@subsection Mixing examples
+
+For example, if you want to down-mix from stereo to mono, but with a bigger
+factor for the left channel:
+@example
+pan=1:c0=0.9*c0+0.1*c1
+@end example
+
+A customized down-mix to stereo that works automatically for 3-, 4-, 5- and
+7-channels surround:
+@example
+pan=stereo: FL < FL + 0.5*FC + 0.6*BL + 0.6*SL : FR < FR + 0.5*FC + 0.6*BR + 0.6*SR
+@end example
+
+Note that @command{ffmpeg} integrates a default down-mix (and up-mix) system
+that should be preferred (see "-ac" option) unless you have very specific
+needs.
+
+@subsection Remapping examples
+
+The channel remapping will be effective if, and only if:
+
+@itemize
+@item gain coefficients are zeroes or ones,
+@item only one input per channel output,
+@end itemize
+
+If all these conditions are satisfied, the filter will notify the user ("Pure
+channel mapping detected"), and use an optimized and lossless method to do the
+remapping.
+
+For example, if you have a 5.1 source and want a stereo audio stream by
+dropping the extra channels:
+@example
+pan="stereo: c0=FL : c1=FR"
+@end example
+
+Given the same source, you can also switch front left and front right channels
+and keep the input channel layout:
+@example
+pan="5.1: c0=c1 : c1=c0 : c2=c2 : c3=c3 : c4=c4 : c5=c5"
+@end example
+
+If the input is a stereo audio stream, you can mute the front left channel (and
+still keep the stereo channel layout) with:
+@example
+pan="stereo:c1=c1"
+@end example
+
+Still with a stereo audio stream input, you can copy the right channel in both
+front left and right:
+@example
+pan="stereo: c0=FR : c1=FR"
+@end example
+
+@section silencedetect
+
+Detect silence in an audio stream.
+
+This filter logs a message when it detects that the input audio volume is less
+or equal to a noise tolerance value for a duration greater or equal to the
+minimum detected noise duration.
+
+The printed times and duration are expressed in seconds.
+
+@table @option
+@item duration, d
+Set silence duration until notification (default is 2 seconds).
+
+@item noise, n
+Set noise tolerance. Can be specified in dB (in case "dB" is appended to the
+specified value) or amplitude ratio. Default is -60dB, or 0.001.
+@end table
+
+Detect 5 seconds of silence with -50dB noise tolerance:
+@example
+silencedetect=n=-50dB:d=5
+@end example
+
+Complete example with @command{ffmpeg} to detect silence with 0.0001 noise
+tolerance in @file{silence.mp3}:
+@example
+ffmpeg -f lavfi -i amovie=silence.mp3,silencedetect=noise=0.0001 -f null -
+@end example
+
+@section volume
+
+Adjust the input audio volume.
+
+The filter accepts exactly one parameter @var{vol}, which expresses
+how the audio volume will be increased or decreased.
+
+Output values are clipped to the maximum value.
+
+If @var{vol} is expressed as a decimal number, the output audio
+volume is given by the relation:
+@example
+@var{output_volume} = @var{vol} * @var{input_volume}
+@end example
+
+If @var{vol} is expressed as a decimal number followed by the string
+"dB", the value represents the requested change in decibels of the
+input audio power, and the output audio volume is given by the
+relation:
+@example
+@var{output_volume} = 10^(@var{vol}/20) * @var{input_volume}
+@end example
+
+Otherwise @var{vol} is considered an expression and its evaluated
+value is used for computing the output audio volume according to the
+first relation.
+
+Default value for @var{vol} is 1.0.
+
+@subsection Examples
+
+@itemize
+@item
+Half the input audio volume:
+@example
+volume=0.5
+@end example
+
+The above example is equivalent to:
+@example
+volume=1/2
+@end example
+
+@item
+Decrease input audio power by 12 decibels:
+@example
+volume=-12dB
+@end example
+@end itemize

+This source is mainly intended for a programmatic use, in particular
+through the interface defined in @file{libavfilter/asrc_abuffer.h}.
+
+It accepts the following mandatory parameters:
+@var{sample_rate}:@var{sample_fmt}:@var{channel_layout}:@var{packing}
+
+@table @option
+
+@item sample_rate
+The sample rate of the incoming audio buffers.
+
+@item sample_fmt
+The sample format of the incoming audio buffers.
+Either a sample format name or its corresponging integer representation from
+the enum AVSampleFormat in @file{libavutil/samplefmt.h}
+
+@item channel_layout
+The channel layout of the incoming audio buffers.
+Either a channel layout name from channel_layout_map in
+@file{libavutil/audioconvert.c} or its corresponding integer representation
+from the AV_CH_LAYOUT_* macros in @file{libavutil/audioconvert.h}
+
+@item packing
+Either "packed" or "planar", or their integer representation: 0 or 1
+respectively.
+
+@end table
+
+For example:
+@example
+abuffer=44100:s16:stereo:planar
+@end example
+
+will instruct the source to accept planar 16bit signed stereo at 44100Hz.
+Since the sample format with name "s16" corresponds to the number
+1 and the "stereo" channel layout corresponds to the value 0x3, this is
+equivalent to:
+@example
+abuffer=44100:1:0x3:1
+@end example
+
+@section aevalsrc
+
+Generate an audio signal specified by an expression.
+
+This source accepts in input one or more expressions (one for each
+channel), which are evaluated and used to generate a corresponding
+audio signal.
+
+It accepts the syntax: @var{exprs}[::@var{options}].
+@var{exprs} is a list of expressions separated by ":", one for each
+separate channel. The output channel layout depends on the number of
+provided expressions, up to 8 channels are supported.

+@var{options} is an optional sequence of @var{key}=@var{value} pairs,
+separated by ":".
+
+The description of the accepted options follows.
+
+@table @option
+
+@item duration, d
+Set the minimum duration of the sourced audio. See the function
+@code{av_parse_time()} for the accepted format.
+Note that the resulting duration may be greater than the specified
+duration, as the generated audio is always cut at the end of a
+complete frame.
+
+If not specified, or the expressed duration is negative, the audio is
+supposed to be generated forever.
+
+@item nb_samples, n
+Set the number of samples per channel per each output frame,
+default to 1024.
+
+@item sample_rate, s
+Specify the sample rate, default to 44100.

@chapter Video Filters
@c man begin VIDEO FILTERS
-When you configure your Libav build, you can disable any of the
-existing filters using --disable-filters.
+When you configure your FFmpeg build, you can disable any of the
+existing filters using @code{--disable-filters}.
The configure output will show the video filters included in your
build.
Below is a description of the currently available video filters.
+@section ass
+
+Draw ASS (Advanced Substation Alpha) subtitles on top of input video
+using the libass library.
+
+To enable compilation of this filter you need to configure FFmpeg with
+@code{--enable-libass}.
+
+This filter accepts the syntax: @var{ass_filename}[:@var{options}],
+where @var{ass_filename} is the filename of the ASS file to read, and
+@var{options} is an optional sequence of @var{key}=@var{value} pairs,
+separated by ":".
+
+A description of the accepted options follows.
+
+@table @option
+@item original_size
+Specifies the size of the original video, the video for which the ASS file
+was composed. Due to a misdesign in ASS aspect ratio arithmetic, this is
+necessary to correctly scale the fonts if the aspect ratio has been changed.
+@end table
+
+For example, to render the file @file{sub.ass} on top of the input
+video, use the command:
+@example
+ass=sub.ass
+@end example
+
+@section bbox
+
+Compute the bounding box for the non-black pixels in the input frame
+luminance plane.
+
+This filter computes the bounding box containing all the pixels with a
+luminance value greater than the minimum allowed value.
+The parameters describing the bounding box are printed on the filter
+log.
+
+@section blackdetect
+
+Detect video intervals that are (almost) completely black. Can be
+useful to detect chapter transitions, commercials, or invalid
+recordings. Output lines contains the time for the start, end and
+duration of the detected black interval expressed in seconds.
+
+In order to display the output lines, you need to set the loglevel at
+least to the AV_LOG_INFO value.
+
+This filter accepts a list of options in the form of
+@var{key}=@var{value} pairs separated by ":". A description of the
+accepted options follows.
+
+@table @option
+@item black_min_duration, d
+Set the minimum detected black duration expressed in seconds. It must
+be a non-negative floating point number.
+
+Default value is 2.0.
+
+@item picture_black_ratio_th, pic_th
+Set the threshold for considering a picture "black".
+Express the minimum value for the ratio:
+@example
+@var{nb_black_pixels} / @var{nb_pixels}
+@end example
+
+for which a picture is considered black.
+Default value is 0.98.
+
+@item pixel_black_th, pix_th
+Set the threshold for considering a pixel "black".
+
+The threshold expresses the maximum pixel luminance value for which a
+pixel is considered "black". The provided value is scaled according to
+the following equation:
+@example
+@var{absolute_threshold} = @var{luminance_minimum_value} + @var{pixel_black_th} * @var{luminance_range_size}
+@end example
+
+@var{luminance_range_size} and @var{luminance_minimum_value} depend on
+the input video format, the range is [0-255] for YUV full-range
+formats and [16-235] for YUV non full-range formats.
+
+Default value is 0.10.
+@end table
+
+The following example sets the maximum pixel threshold to the minimum
+value, and detects only black intervals of 2 or more seconds:
+@example
+blackdetect=d=2:pix_th=0.00
+@end example
+
@section blackframe
Detect frames that are (almost) completely black. Can be useful to
Apply boxblur algorithm to the input video.

+@item x, y, w, h
+Specify a rectangular area where to limit the search for motion
+vectors.
+If desired the search for motion vectors can be limited to a

+@section removelogo
+
+Suppress a TV station logo, using an image file to determine which
+pixels comprise the logo. It works by filling in the pixels that
+comprise the logo with neighboring pixels.
+
+This filter requires one argument which specifies the filter bitmap
+file, which can be any image format supported by libavformat. The
+width and height of the image file must match those of the video
+stream being processed.
+
+Pixels in the provided bitmap image with a value of zero are not
+considered part of the logo, non-zero pixels are considered part of
+the logo. If you use white (255) for the logo and black (0) for the
+rest, you will be safe. For making the filter bitmap, it is
+recommended to take a screen capture of a black frame with the logo
+visible, and then using a threshold filter followed by the erode
+filter once or twice.
+
+If needed, little splotches can be fixed manually. Remember that if
+logo pixels are not covered, the filter quality will be much
+reduced. Marking too many pixels as part of the logo does not hurt as
+much, but it will increase the amount of blurring needed to cover over
+the image and will destroy more information than necessary, and extra
+pixels will slow things down on a large logo.

+
+@section thumbnail
+Select the most representative frame in a given sequence of consecutive frames.
+
+It accepts as argument the frames batch size to analyze (default @var{N}=100);
+in a set of @var{N} frames, the filter will pick one of them, and then handle
+the next batch of @var{N} frames until the end.
+
+Since the filter keeps track of the whole frames sequence, a bigger @var{N}
+value will result in a higher memory usage, so a high value is not recommended.
+

+@section life
+
+Generate a life pattern.
+
+This source is based on a generalization of John Conway's life game.
+
+The sourced input represents a life grid, each pixel represents a cell
+which can be in one of two possible states, alive or dead. Every cell
+interacts with its eight neighbours, which are the cells that are
+horizontally, vertically, or diagonally adjacent.
+
+At each interaction the grid evolves according to the adopted rule,
+which specifies the number of neighbor alive cells which will make a
+cell stay alive or born. The @option{rule} option allows to specify
+the rule to adopt.
+
+This source accepts a list of options in the form of
+@var{key}=@var{value} pairs separated by ":". A description of the
+accepted options follows.
+
+@table @option
+@item filename, f
+Set the file from which to read the initial grid state. In the file,
+each non-whitespace character is considered an alive cell, and newline
+is used to delimit the end of each row.
+
+If this option is not specified, the initial grid is generated
+randomly.
+
+@item rate, r
+Set the video rate, that is the number of frames generated per second.
+Default is 25.
+
+@item random_fill_ratio, ratio
+Set the random fill ratio for the initial random grid. It is a
+floating point number value ranging from 0 to 1, defaults to 1/PHI.
+It is ignored when a file is specified.
+
+@item random_seed, seed
+Set the seed for filling the initial random grid, must be an integer
+included between 0 and UINT32_MAX. If not specified, or if explicitly
+set to -1, the filter will try to use a good random seed on a best
+effort basis.
+
+@item rule
+Set the life rule.
+
+A rule can be specified with a code of the kind "S@var{NS}/B@var{NB}",
+where @var{NS} and @var{NB} are sequences of numbers in the range 0-8,
+@var{NS} specifies the number of alive neighbor cells which make a
+live cell stay alive, and @var{NB} the number of alive neighbor cells
+which make a dead cell to become alive (i.e. to "born").
+"s" and "b" can be used in place of "S" and "B", respectively.
+
+Alternatively a rule can be specified by an 18-bits integer. The 9
+high order bits are used to encode the next cell state if it is alive
+for each number of neighbor alive cells, the low order bits specify
+the rule for "borning" new cells. Higher order bits encode for an
+higher number of neighbor cells.
+For example the number 6153 = @code{(12<<9)+9} specifies a stay alive
+rule of 12 and a born rule of 9, which corresponds to "S23/B03".
+
+Default value is "S23/B3", which is the original Conway's game of life
+rule, and will keep a cell alive if it has 2 or 3 neighbor alive
+cells, and will born a new cell if there are three alive cells around
+a dead cell.
+
+@item size, s
+Set the size of the output video.
+
+If @option{filename} is specified, the size is set by default to the
+same size of the input file. If @option{size} is set, it must contain
+the size specified in the input file, and the initial grid defined in
+that file is centered in the larger resulting area.
+
+If a filename is not specified, the size value defaults to "320x240"
+(used for a randomly generated initial grid).
+
+@item stitch
+If set to 1, stitch the left and right grid edges together, and the
+top and bottom edges also. Defaults to 1.
+
+@item mold
+Set cell mold speed. If set, a dead cell will go from @option{death_color} to
+@option{mold_color} with a step of @option{mold}. @option{mold} can have a
+value from 0 to 255.
+
+@item life_color
+Set the color of living (or new born) cells.
+
+@item death_color
+Set the color of dead cells. If @option{mold} is set, this is the first color
+used to represent a dead cell.

@section libdc1394
IIDC1394 input device, based on libdc1394 and libraw1394.
+@section openal
+
+The OpenAL input device provides audio capture on all systems with a
+working OpenAL 1.1 implementation.
+
+To enable this input device during configuration, you need OpenAL
+headers and libraries installed on your system, and need to configure
+FFmpeg with @code{--enable-openal}.
+
+OpenAL headers and libraries should be provided as part of your OpenAL
+implementation, or as an additional download (an SDK). Depending on your
+installation you may need to specify additional flags via the
+@code{--extra-cflags} and @code{--extra-ldflags} for allowing the build
+system to locate the OpenAL headers and libraries.
+
+An incomplete list of OpenAL implementations follows:
+
+@table @strong
+@item Creative
+The official Windows implementation, providing hardware acceleration
+with supported devices and software fallback.
+See @url{http://openal.org/}.
+@item OpenAL Soft
+Portable, open source (LGPL) software implementation. Includes
+backends for the most common sound APIs on the Windows, Linux,
+Solaris, and BSD operating systems.
+See @url{http://kcat.strangesoft.net/openal.html}.
+@item Apple
+OpenAL is part of Core Audio, the official Mac OS X Audio interface.
+See @url{http://developer.apple.com/technologies/mac/audio-and-video.html}
+@end table
+
+This device allows to capture from an audio input device handled
+through OpenAL.
+
+You need to specify the name of the device to capture in the provided
+filename. If the empty string is provided, the device will
+automatically select the default device. You can get the list of the
+supported devices by using the option @var{list_devices}.
+
+@subsection Options
+
+@table @option
+
+@item channels
+Set the number of channels in the captured audio. Only the values
+@option{1} (monaural) and @option{2} (stereo) are currently supported.
+Defaults to @option{2}.
+
+@item sample_size
+Set the sample size (in bits) of the captured audio. Only the values
+@option{8} and @option{16} are currently supported. Defaults to
+@option{16}.
+
+@item sample_rate
+Set the sample rate (in Hz) of the captured audio.
+Defaults to @option{44.1k}.
+
+@item list_devices
+If set to @option{true}, print a list of devices and exit.
+Defaults to @option{false}.
+
+@end table
+
+@subsection Examples
+
+Print the list of OpenAL supported devices and exit:
+@example
+$ ffmpeg -list_devices true -f openal -i dummy out.ogg
+@end example
+
+Capture from the OpenAL device @file{DR-BT101 via PulseAudio}:
+@example
+$ ffmpeg -f openal -i 'DR-BT101 via PulseAudio' out.ogg
+@end example
+
+Capture from the default device (note the empty string '' as filename):
+@example
+$ ffmpeg -f openal -i '' out.ogg
+@end example
+
+Capture from two devices simultaneously, writing to two different files,
+within the same @command{ffmpeg} command:
+@example
+$ ffmpeg -f openal -i 'DR-BT101 via PulseAudio' out1.ogg -f openal -i 'ALSA Default' out2.ogg
+@end example
+Note: not all OpenAL implementations support multiple simultaneous capture -
+try the latest OpenAL Soft if the above does not work.

+FFmpeg's bug/patch/feature request tracker manual
+=================================================
+
+NOTE: This is a draft.
+
+Overview:
+---------
+
+FFmpeg uses Trac for tracking issues, new issues and changes to
+existing issues can be done through a web interface.
+
+Issues can be different kinds of things we want to keep track of
+but that do not belong into the source tree itself. This includes
+bug reports, patches, feature requests and license violations. We
+might add more items to this list in the future, so feel free to
+propose a new `type of issue' on the ffmpeg-devel mailing list if
+you feel it is worth tracking.
+
+It is possible to subscribe to individual issues by adding yourself to the
+Cc list or to subscribe to the ffmpeg-trac mailing list which receives
+a mail for every change to every issue.
+(the above does all work already after light testing)
+
+The subscription URL for the ffmpeg-trac list is:
+http(s)://ffmpeg.org/mailman/listinfo/ffmpeg-trac
+The URL of the webinterface of the tracker is:
+http(s)://ffmpeg.org/trac/ffmpeg
+
+Type:
+-----
+bug / defect
+ An error, flaw, mistake, failure, or fault in FFmpeg or libav* that
+ prevents it from behaving as intended.
+
+feature request / enhancement
+ Request of support for encoding or decoding of a new codec, container
+ or variant.
+ Request of support for more, less or plain different output or behavior
+ where the current implementation cannot be considered wrong.
+
+license violation
+ ticket to keep track of (L)GPL violations of ffmpeg by others
+
+patch
+ A patch as generated by diff which conforms to the patch submission and
+ development policy.
+
+
+Priority:
+---------
+critical
+ Bugs and patches which deal with data loss and security issues.
+ No feature request can be critical.
+
+important
+ Bugs which make FFmpeg unusable for a significant number of users, and
+ patches fixing them.
+ Examples here might be completely broken MPEG-4 decoding or a build issue
+ on Linux.
+ While broken 4xm decoding or a broken OS/2 build would not be important,
+ the separation to normal is somewhat fuzzy.
+ For feature requests this priority would be used for things many people
+ want.
+ Regressions also should be marked as important, regressions are bugs that
+ don't exist in a past revision or another branch.
+
+normal
+
+
+minor
+ Bugs and patches about things like spelling errors, "mp2" instead of
+ "mp3" being shown and such.
+ Feature requests about things few people want or which do not make a big
+ difference.
+
+wish
+ Something that is desirable to have but that there is no urgency at
+ all to implement, e.g. something completely cosmetic like a website
+ restyle or a personalized doxy template or the FFmpeg logo.
+ This priority is not valid for bugs.
+
+
+Status:

+
+closed
+ final state
+
+
+Analyzed flag:
+--------------
+Bugs which have been analyzed and where it is understood what causes them
+and which exact chain of events triggers them. This analysis should be
+available as a message in the bug report.
+Note, do not change the status to analyzed without also providing a clear
+and understandable analysis.
+This state implicates that the bug either has been reproduced or that
+reproduction is not needed as the bug is already understood.
+
+
+Type/Status/Substatus:
+----------
+*/new/new
+ Initial state of new bugs, patches and feature requests submitted by
+ users.
+
+*/open/open
+ Issues which have been briefly looked at and which did not look outright
+ invalid.
+ This implicates that no real more detailed state applies yet. Conversely,
+ the more detailed states below implicate that the issue has been briefly
+ looked at.
+
+*/closed/duplicate
+ Bugs, patches or feature requests which are duplicates.
+ Note that patches dealing with the same thing in a different way are not
+ duplicates.
+ Note, if you mark something as duplicate, do not forget setting the
+ superseder so bug reports are properly linked.
+
+*/closed/invalid
+ Bugs caused by user errors, random ineligible or otherwise nonsense stuff.
+
+*/closed/needs_more_info
+ Issues for which some information has been requested by the developers,
+ but which has not been provided by anyone within reasonable time.
+
+
+bug/closed/fixed
+ Bugs which have to the best of our knowledge been fixed.
+
+bug/closed/wont_fix
+ Bugs which we will not fix. Possible reasons include legality, high
+ complexity for the sake of supporting obscure corner cases, speed loss
+ for similarly esoteric purposes, et cetera.
+ This also means that we would reject a patch.
+ If we are just too lazy to fix a bug then the correct state is open
+ and unassigned. Closed means that the case is closed which is not
+ the case if we are just waiting for a patch.
+
+bug/closed/works_for_me
+ Bugs for which sufficient information was provided to reproduce but
+ reproduction failed - that is the code seems to work correctly to the
+ best of our knowledge.
+
+patch/open/approved
+ Patches which have been reviewed and approved by a developer.
+ Such patches can be applied anytime by any other developer after some
+ reasonable testing (compile + regression tests + does the patch do
+ what the author claimed).
+
+patch/open/needs_changes
+ Patches which have been reviewed and need changes to be accepted.
+
+patch/closed/applied
+ Patches which have been applied.
+
+patch/closed/rejected
+ Patches which have been rejected.
+
+feature_request/closed/implemented
+ Feature requests which have been implemented.
+
+feature_request/closed/wont_implement
+ Feature requests which will not be implemented. The reasons here could
+ be legal, philosophical or others.
+
+Note, please do not use type-status-substatus combinations other than the
+above without asking on ffmpeg-dev first!

+
+/*
+ * - Principles of Operation -
+ *
+ * The CrystalHD decoder operates at the bitstream level - which is an even
+ * higher level than the decoding hardware you typically see in modern GPUs.
+ * This means it has a very simple interface, in principle. You feed demuxed
+ * packets in one end and get decoded picture (fields/frames) out the other.
+ *
+ * Of course, nothing is ever that simple. Due, at the very least, to b-frame
+ * dependencies in the supported formats, the hardware has a delay between
+ * when a packet goes in, and when a picture comes out. Furthermore, this delay
+ * is not just a function of time, but also one of the dependency on additional
+ * frames being fed into the decoder to satisfy the b-frame dependencies.
+ *
+ * As such, a pipeline will build up that is roughly equivalent to the required
+ * DPB for the file being played. If that was all it took, things would still
+ * be simple - so, of course, it isn't.
+ *
+ * The hardware has a way of indicating that a picture is ready to be copied out,
+ * but this is unreliable - and sometimes the attempt will still fail so, based
+ * on testing, the code will wait until 3 pictures are ready before starting
+ * to copy out - and this has the effect of extending the pipeline.
+ *
+ * Finally, while it is tempting to say that once the decoder starts outputing
+ * frames, the software should never fail to return a frame from a decode(),
+ * this is a hard assertion to make, because the stream may switch between
+ * differently encoded content (number of b-frames, interlacing, etc) which
+ * might require a longer pipeline than before. If that happened, you could
+ * deadlock trying to retrieve a frame that can't be decoded without feeding
+ * in additional packets.
+ *
+ * As such, the code will return in the event that a picture cannot be copied
+ * out, leading to an increase in the length of the pipeline. This in turn,
+ * means we have to be sensitive to the time it takes to decode a picture;
+ * We do not want to give up just because the hardware needed a little more
+ * time to prepare the picture! For this reason, there are delays included
+ * in the decode() path that ensure that, under normal conditions, the hardware
+ * will only fail to return a frame if it really needs additional packets to
+ * complete the decoding.
+ *
+ * Finally, to be explicit, we do not want the pipeline to grow without bound
+ * for two reasons: 1) The hardware can only buffer a finite number of packets,
+ * and 2) The client application may not be able to cope with arbitrarily long
+ * delays in the video path relative to the audio path. For example. MPlayer
+ * can only handle a 20 picture delay (although this is arbitrary, and needs
+ * to be extended to fully support the CrystalHD where the delay could be up
+ * to 32 pictures - consider PAFF H.264 content with 16 b-frames).

method suggested in SMPTE 314M Table 22, and an improved
method. The SMPTE method is very conservative; it assigns class
3 (i.e. severe quantization) to any block where the largest AC
- component is greater than 36. Libav's DV encoder tracks AC bit
+ component is greater than 36. FFmpeg's DV encoder tracks AC bit
consumption precisely, so there is no need to bias most blocks
towards strongly lossy compression. Instead, we assign class 2
to most blocks, and use class 3 only when strictly necessary

+" For VBR modes (generally highest quality):\n"\
+"\n"\
+" \"preset=standard\" This preset should generally be transparent\n"\
+" to most people on most music and is already\n"\
+" quite high in quality.\n"\
+"\n"\
+" \"preset=extreme\" If you have extremely good hearing and similar\n"\
+" equipment, this preset will generally provide\n"\
+" slightly higher quality than the \"standard\"\n"\
+" mode.\n"\
+"\n"\
+" For CBR 320kbps (highest quality possible from the preset switches):\n"\
+"\n"\
+" \"preset=insane\" This preset will usually be overkill for most\n"\
+" people and most situations, but if you must\n"\
+" have the absolute highest quality with no\n"\
+" regard to filesize, this is the way to go.\n"\
+"\n"\
+" For ABR modes (high quality per given bitrate but not as high as VBR):\n"\
+"\n"\
+" \"preset=<kbps>\" Using this preset will usually give you good\n"\
+" quality at a specified bitrate. Depending on the\n"\
+" bitrate entered, this preset will determine the\n"\
+" optimal settings for that particular situation.\n"\
+" While this approach works, it is not nearly as\n"\
+" flexible as VBR, and usually will not attain the\n"\

+" \"fast\" - Enables the new fast VBR for a particular profile. The\n"\
+" disadvantage to the speed switch is that often times the\n"\
+" bitrate will be slightly higher than with the normal mode\n"\
+" and quality may be slightly lower also.\n"\
+" Warning: with the current version fast presets might result in too\n"\
+" high bitrate compared to regular presets.\n"\
+"\n"\

+ * filter to output only 1 every n frame, or only the I (key)frame
+ *
+ * The parameters are:
+ *
+ * [I] | [i]num
+ *
+ * if you call the filter with I (uppercase) as the parameter
+ * ... -vf framestep=I ...
+ * then ONLY the keyframes are outputted.
+ * For DVD it means, generally, one every 15 frames (IBBPBBPBBPBBPBB), for avi it means
+ * every scene change or every keyint value (see -lavcopts).
+ *
+ * if you call the filter with the i (lowercase)
+ * ... -vf framestep=i ...
+ * then a I! followed by a cr is printed when a key frame (eg Intra frame) is
+ * found, leaving the current line of mplayer/mencoder, where you got the
+ * time, in seconds, and frame of the key. Use this information to split the
+ * AVI.
+ *
+ * After the i or alone you can put a positive number and only one frame every
+ * x (the number you set) is passed on the filter chain, limiting the output
+ * of the frame.
+ *
+ * Example
+ * ... -vf framestep=i20 ...
+ * Dump one every 20 frames, printing on the console when a I-Frame is encounter.
+ *
+ * ... -vf framestep=25
+ * Dump one every 25 frames.
+ *
+ * If you call the filter without parameter it does nothing (except using memory
+ * and resource of your system,. of course).
+ *
+ * This filter doesn' t work like the option -sstep seconds.
+ *
+ * The -sstep seek to the new position, without decoding all frames but,
+ * expecially on avi file coded whith mpeg4 (lavc or xvid or divx), the
+ * seek is not always too much precise.
+ *
+ * This filter simply discard the unwanted frames, so you are very precise in
+ * counting the frame but sometime you use a lot of CPU for nothing.
+ *
+ * As usual it depends on what you're doing.

+Known Issues:
+* The motion estimation is somewhat at the mercy of the input, if the input
+ frames are created purely based on spatial interpolation then for example
+ a thin black line or another random and not interpolateable pattern
+ will cause problems
+ Note: completly ignoring the "unavailable" lines during motion estimation
+ didnt look any better, so the most obvious solution would be to improve
+ tfields or penalize problematic motion vectors ...
+
+* If non iterative ME is used then snow currently ignores the OBMC window
+ and as a result sometimes creates artifacts
+
+* only past frames are used, we should ideally use future frames too, something
+ like filtering the whole movie in forward and then backward direction seems
+ like a interresting idea but the current filter framework is FAR from
+ supporting such things
+
+* combining the motion compensated image with the input image also isnt
+ as trivial as it seems, simple blindly taking even lines from one and
+ odd ones from the other doesnt work at all as ME/MC sometimes simple
+ has nothing in the previous frames which matches the current, the current
+ algo has been found by trial and error and almost certainly can be
+ improved ...

+ * filter to tile a serie of image in a single, bigger, image
+ *
+ * The parameters are:
+ *
+ * xtile: number of tile on the x axis (5)
+ * ytile: number of tile on the y axis (5)
+ * xytile: when write the image, it can be different then xtile * ytile
+ * (for example you can write 8 * 7 tile, writing the file every
+ * 50 frame, to have one image every 2 seconds @ 25 fps ).
+ * start: pixel at the start (x/y), default 2
+ * delta: pixel between 2 tile, (x/y), default 4
+ *
+ * For example a valid command line is:
+ * ... -vf tile=10:5:-1:4:8 ...
+ * that make images of 10 * 5 tiles, with 4 pixel at the beginning and
+ * 8 pixel between tiles.
+ *
+ * The default command is:
+ * ... -vf tile=5:5:25:2:4
+ *
+ * If you omit a parameter or put a value less then 0, the default is used.
+ * ... -vf tile=10:5::-1:10
+ *
+ * You can also stop when you're ok
+ * ... -vf tile=10:5
+ * (and this is probably the option you will use more often ...)
+ *
+ * Probably is good to put the scale filter before the tile :-)

+ *
+ * SAD block-matching motion compensation to fix small changes in
+ * horizontal and/or vertical shift. This filter helps remove camera shake
+ * from hand-holding a camera, bumping a tripod, moving on a vehicle, etc.
+ *
+ * Algorithm:
+ * - For each frame with one previous reference frame
+ * - For each block in the frame
+ * - If contrast > threshold then find likely motion vector
+ * - For all found motion vectors
+ * - Find most common, store as global motion vector
+ * - Find most likely rotation angle
+ * - Transform image along global motion
+ *
+ * TODO:
+ * - Fill frame edges based on previous/next reference frames
+ * - Fill frame edges by stretching image near the edges?
+ * - Can this be done quickly and look decent?
+ *
+ * Dark Shikari links to http://wiki.videolan.org/SoC_x264_2010#GPU_Motion_Estimation_2
+ * for an algorithm similar to what could be used here to get the gmv
+ * It requires only a couple diamond searches + fast downscaling
+ *
+ * Special thanks to Jason Kotenko for his help with the algorithm and my
+ * inability to see simple errors in C code.

+/**
+ * @file advanced blur-based logo removing filter
+ *
+ * This filter loads an image mask file showing where a logo is and
+ * uses a blur transform to remove the logo.
+ *
+ * Based on the libmpcodecs remove-logo filter by Robert Edele.
+ */
+
+/**
+ * This code implements a filter to remove annoying TV logos and other annoying
+ * images placed onto a video stream. It works by filling in the pixels that
+ * comprise the logo with neighboring pixels. The transform is very loosely
+ * based on a gaussian blur, but it is different enough to merit its own
+ * paragraph later on. It is a major improvement on the old delogo filter as it
+ * both uses a better blurring algorithm and uses a bitmap to use an arbitrary
+ * and generally much tighter fitting shape than a rectangle.
+ *
+ * The logo removal algorithm has two key points. The first is that it
+ * distinguishes between pixels in the logo and those not in the logo by using
+ * the passed-in bitmap. Pixels not in the logo are copied over directly without
+ * being modified and they also serve as source pixels for the logo
+ * fill-in. Pixels inside the logo have the mask applied.
+ *
+ * At init-time the bitmap is reprocessed internally, and the distance to the
+ * nearest edge of the logo (Manhattan distance), along with a little extra to
+ * remove rough edges, is stored in each pixel. This is done using an in-place
+ * erosion algorithm, and incrementing each pixel that survives any given
+ * erosion. Once every pixel is eroded, the maximum value is recorded, and a
+ * set of masks from size 0 to this size are generaged. The masks are circular
+ * binary masks, where each pixel within a radius N (where N is the size of the
+ * mask) is a 1, and all other pixels are a 0. Although a gaussian mask would be
+ * more mathematically accurate, a binary mask works better in practice because
+ * we generally do not use the central pixels in the mask (because they are in
+ * the logo region), and thus a gaussian mask will cause too little blur and
+ * thus a very unstable image.
+ *
+ * The mask is applied in a special way. Namely, only pixels in the mask that
+ * line up to pixels outside the logo are used. The dynamic mask size means that
+ * the mask is just big enough so that the edges touch pixels outside the logo,
+ * so the blurring is kept to a minimum and at least the first boundary
+ * condition is met (that the image function itself is continuous), even if the
+ * second boundary condition (that the derivative of the image function is
+ * continuous) is not met. A masking algorithm that does preserve the second
+ * boundary coundition (perhaps something based on a highly-modified bi-cubic
+ * algorithm) should offer even better results on paper, but the noise in a
+ * typical TV signal should make anything based on derivatives hopelessly noisy.

+ * Small buffers are kept in the structure itself, and thus require no

+ * declaring a local "char buf[512]".
+ *
+ * The length of the string can go beyond the allocated size: the buffer is
+ * then truncated, but the functions still keep account of the actual total
+ * length.

+ * In other words, buf->len can be greater than buf->size and records the
+ * total length of what would have been to the buffer if there had been
+ * enough memory.

+ * allocation fails, data stop being appended to the buffer, but the length
+ * is still updated. This situation can be tested with

+ * The size_max field determines several possible behaviours:

+ * reallocated as necessary, with an amortized linear cost.
+ *
+ * size_max = 0 prevents writing anything to the buffer: only the total
+ * length is computed. The write operations can then possibly be repeated in
+ * a buffer with exactly the necessary size
+ * (using size_init = size_max = len + 1).
+ *
+ * size_max = 1 is automatically replaced by the exact size available in the

- The better method should be "left bit replication":

+Todo
+
+-- For other people
+- Multithread vc1.
+- Multithread an intra codec like mjpeg (trivial).
+- Fix mpeg1 (see below).
+- Try the first three items under Optimization.
+- Fix h264 (see below).
+- Try mpeg4 (see below).
+
+-- Bug fixes
+
+General critical:
+- Error resilience has to run before ff_report_frame_progress()
+is called. Otherwise there will be race conditions. (This might already
+work.) In general testing error paths should be done more.
+- 'make fate THREADS=2' doesn't pass. Most failures are due to
+bugs in vsync in ffmpeg.c, which are currently obscuring real failures.
+
+h264:
+- Files that aren't parsed (e.g. mp4) and contain PAFF with two
+field pictures in the same packet are not optimal. Modify the
+nals_needed check so that the second field's first slice is
+considered as needed, then uncomment the FIXME code in decode_postinit.
+Ex: http://astrange.ithinksw.net/ffmpeg/mt-samples/PAFF-Chalet-Tire.mp4
+
+mpeg4:
+- Packed B-frames need to be explicitly split up
+when frame threading is on. It's not very fast
+without this.
+- The buffer age optimization is disabled due to
+the way buffers are allocated across threads. The
+branch 'fix_buffer_age' has an attempt to fix it
+which breaks ffplay.
+- Support interlaced.
+
+mpeg1/2:
+- Seeking always prints "first frame not a keyframe"
+with threads on. Currently disabled for this reason.
+
+-- Prove correct
+
+- decode_update_progress() in h264.c
+race_checking branch has some work on h264,
+but not that function. It might be worth putting
+the branch under #ifdef DEBUG in mainline, but
+the code would have to be cleaner.
+- MPV_lowest_referenced_row() and co in mpegvideo.c
+- Same in vp3.
+
+-- Optimization
+
+- Merge h264 decode_update_progress() with loop_filter().
+Add CODEC_CAP_DRAW_HORIZ_BAND as a side effect.
+- EMU_EDGE is always set for h264 PAFF+MT
+because draw_edges() writes into the other field's
+thread's pixels. Needs an option to skip T/B fields.
+- Check update_thread_context() functions and make
+sure they only copy what they need to.
+- Try some more optimization of the "ref < 48; ref++"
+loop in h264.c await_references(), try turning the list0/list1 check
+above into a loop without being slower.
+- Support frame+slice threading at the same time
+by assigning slice_count threads for frame threads
+to use with execute(). This is simpler but unbalanced
+if only one frame thread uses any.
+
+-- Features
+
+- Support streams with width/height changing. This
+requires flushing all current frames (and buffering
+the input in the meantime), closing the codec and
+reopening it. Or don't support it.
+- Support encoding. Might need more threading primitives
+for good ratecontrol; would be nice for audio and libavfilter too.
+- Async decoding part 1: instead of trying to
+start every thread at the beginning, return a picture
+if the earliest thread is already done, but don't wait
+for it. Not sure what effect this would have.
+- Part 2: have an API that doesn't wait for the decoding
+thread, only returns EAGAIN if it's not ready. What will
+it do with the next input packet if it returns that?
+- Have an API that returns finished pictures but doesn't
+require sending new ones. Maybe allow NULL avpkt when
+not at the end of the stream.
+
+-- Samples
+
+http://astrange.ithinksw.net/ffmpeg/mt-samples/
+
+See yuvcmp.c in this directory to compare decoded samples.
+
+For debugging, try commenting out ff_thread_finish_setup calls so
+that only one thread runs at once, and then binary search+
+scatter printfs to look for differences in codec contexts.
