- lavfi input device added
 | 
			
		||||
- added avconv, which is almost the same for now, except
 | 
			
		||||
for a few incompatible changes in the options, which will hopefully make them
 | 
			
		||||
easier to use. The changes are:
 | 
			
		||||
    * The options placement is now strictly enforced! While in theory the
 | 
			
		||||
      options for ffmpeg should be given in [input options] -i INPUT [output
 | 
			
		||||
      options] OUTPUT order, in practice it was possible to give output options
 | 
			
		||||
      before the -i and it mostly worked. Except when it didn't - the behavior was
 | 
			
		||||
      a bit inconsistent. In avconv, it is not possible to mix input and output
 | 
			
		||||
      options. All non-global options are reset after an input or output filename.
 | 
			
		||||
    * All per-file options are now truly per-file - they apply only to the next
 | 
			
		||||
      input or output file and specifying different values for different files
 | 
			
		||||
      will now work properly (notably -ss and -t options).
 | 
			
		||||
    * All per-stream options are now truly per-stream - it is possible to
 | 
			
		||||
      specify which stream(s) should a given option apply to. See the Stream
 | 
			
		||||
      specifiers section in the avconv manual for details.
 | 
			
		||||
    * In ffmpeg some options (like -newvideo/-newaudio/...) are irregular in the
 | 
			
		||||
      sense that they're specified after the output filename instead of before,
 | 
			
		||||
      like all other options. In avconv this irregularity is removed, all options
 | 
			
		||||
      apply to the next input or output file.
 | 
			
		||||
    * -newvideo/-newaudio/-newsubtitle options were removed. Not only were they
 | 
			
		||||
      irregular and highly confusing, they were also redundant. In avconv the -map
 | 
			
		||||
      option will create new streams in the output file and map input streams to
 | 
			
		||||
      them. E.g. avconv -i INPUT -map 0 OUTPUT will create an output stream for
 | 
			
		||||
      each stream in the first input file.
 | 
			
		||||
    * The -map option now has slightly different and more powerful syntax:
 | 
			
		||||
        + Colons (':') are used to separate file index/stream type/stream index
 | 
			
		||||
          instead of dots. Comma (',') is used to separate the sync stream instead
 | 
			
		||||
          of colon.. This is done for consistency with other options.
 | 
			
		||||
        + It's possible to specify stream type. E.g. -map 0:a:2 creates an
 | 
			
		||||
          output stream from the third input audio stream.
 | 
			
		||||
        + Omitting the stream index now maps all the streams of the given type,
 | 
			
		||||
          not just the first. E.g. -map 0:s creates output streams for all the
 | 
			
		||||
          subtitle streams in the first input file.
 | 
			
		||||
        + Since -map can now match multiple streams, negative mappings were
 | 
			
		||||
          introduced. Negative mappings disable some streams from an already
 | 
			
		||||
          defined map. E.g. '-map 0 -map -0:a:1' means 'create output streams for
 | 
			
		||||
          all the stream in the first input file, except for the second audio
 | 
			
		||||
          stream'.
 | 
			
		||||
    * There is a new option -c (or -codec) for choosing the decoder/encoder to
 | 
			
		||||
      use, which allows to precisely specify target stream(s) consistently with
 | 
			
		||||
      other options. E.g. -c:v lib264 sets the codec for all video streams, -c:a:0
 | 
			
		||||
      libvorbis sets the codec for the first audio stream and -c copy copies all
 | 
			
		||||
      the streams without reencoding. Old -vcodec/-acodec/-scodec options are now
 | 
			
		||||
      aliases to -c:v/a/s
 | 
			
		||||
    * It is now possible to precisely specify which stream should an AVOption
 | 
			
		||||
      apply to. E.g. -b:v:0 2M sets the bitrate for the first video stream, while
 | 
			
		||||
      -b:a 128k sets the bitrate for all audio streams. Note that the old -ab 128k
 | 
			
		||||
      syntax is deprecated and will stop working soon.
 | 
			
		||||
    * -map_chapters now takes only an input file index and applies to the next
 | 
			
		||||
      output file. This is consistent with how all the other options work.
 | 
			
		||||
    * -map_metadata now takes only an input metadata specifier and applies to
 | 
			
		||||
      the next output file. Output metadata specifier is now part of the option
 | 
			
		||||
      name, similarly to the AVOptions/map/codec feature above.
 | 
			
		||||
    * -metadata can now be used to set metadata on streams and chapters, e.g.
 | 
			
		||||
      -metadata:s:1 language=eng sets the language of the first stream to 'eng'.
 | 
			
		||||
      This made -vlang/-alang/-slang options redundant, so they were removed.
 | 
			
		||||
    * -qscale option now uses stream specifiers and applies to all streams, not
 | 
			
		||||
      just video. I.e. plain -qscale number would now apply to all streams. To get
 | 
			
		||||
      the old behavior, use -qscale:v. Also there is now a shortcut -q for -qscale
 | 
			
		||||
      and -aq is now an alias for -q:a.
 | 
			
		||||
    * -vbsf/-absf/-sbsf options were removed and replaced by a -bsf option which
 | 
			
		||||
      uses stream specifiers. Use -bsf:v/a/s instead of the old options.
 | 
			
		||||
    * -itsscale option now uses stream specifiers, so its argument is only the
 | 
			
		||||
      scale parameter.
 | 
			
		||||
    * -intra option was removed, use -g 0 for the same effect.
 | 
			
		||||
    * -psnr option was removed, use -flags +psnr for the same effect.
 | 
			
		||||
    * -vf option is now an alias to the new -filter option, which uses stream specifiers.
 | 
			
		||||
    * -vframes/-aframes/-dframes options are now aliases to the new -frames option.
 | 
			
		||||
    * -vtag/-atag/-stag options are now aliases to the new -tag option.

=============
 | 
			
		||||
 | 
			
		||||
* 0.10 "Freedom"  January, 2012
 | 
			
		||||
* 0.8 "Love"  June, 2011
 | 
			
		||||
* 0.7 "Peace" June, 2011 (identical to 0.8 but using 0.6 ABI/API)

General notes
 | 
			
		||||
-------------
 | 
			
		||||
This release is binary compatible with 0.8 and 0.9.
 | 
			
		||||
 | 
			
		||||
See the Changelog file for a list of significant changes. Note, there
 | 
			
		||||
are many more new features and bugfixes than whats listed there.
 | 
			
		||||
This release enables frame-based multithreaded decoding for a number of codecs,
 | 
			
		||||
including theora, huffyuv, VP8, H.263, mpeg4 and H.264. Additionally, there has
 | 
			
		||||
been a major cleanup of
 | 
			
		||||
both internal and external APIs. For this reason, the major versions of all
 | 
			
		||||
libraries except libpostproc have been bumped. This means that 0.8 can be installed
 | 
			
		||||
side-by-side with previous releases, on the other hand applications need to be
 | 
			
		||||
recompiled to use 0.8.
 | 
			
		||||
 | 
			
		||||
Other important changes are more than 200 bugfixes, known regressions were fixed
 | 
			
		||||
w.r.t 0.5 and 0.6, additions of decoders including, but not limited to,
 | 
			
		||||
AMR-WB, single stream LATM/LOAS, G.722 ADPCM, a native VP8 decoder
 | 
			
		||||
and HE-AACv2. Additionally, many new de/muxers such as WebM in Matroska, Apple
 | 
			
		||||
HTTP Live Streaming, SAP, IEC 61937 (S/PDIF) have been added.
 | 
			
		||||
 | 
			
		||||
See the Changelog file for a list of significant changes.
 | 
			
		||||
 | 
			
		||||

API changes
 | 
			
		||||
-----------
 | 
			
		||||
 | 
			
		||||
A number of additional APIs have been introduced and some existing
 | 
			
		||||
functions have been deprecated and are scheduled for removal in the next
 | 
			
		||||
release. Significant API changes include:
 | 
			
		||||
 | 
			
		||||
* new audio decoding API which decodes from an AVPacket to an AVFrame and
 | 
			
		||||
is able to use AVCodecContext.get_buffer() in the similar way as video decoding.
 | 
			
		||||
 | 
			
		||||
* new audio encoding API which encodes from an AVFrame to an AVPacket, thus
 | 
			
		||||
allowing it to properly output timing information and side data.
 | 
			
		||||
 | 
			
		||||
Please see the git history and the file doc/APIchanges for details.
 | 
			
		||||
Please see git log of the public headers or the file doc/APIchanges for
 | 
			
		||||
programmer-centric information. Note that some long-time deprecated APIs have
 | 
			
		||||
been removed. Also, a number of additional APIs have been deprecated and might
 | 
			
		||||
be removed in the next release.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
Other notable changes
 | 
			
		||||
---------------------
 | 
			
		||||
 | 
			
		||||
Libavcodec and libavformat built as shared libraries now hide non-public
 | 
			
		||||
symbols. This will break applications using those symbols. Possible solutions
 | 
			
		||||
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 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.
 | 
			
		||||
 | 
			
		||||
Please see the Changelog file and git history for a more detailed list of changes.

All the numerical options, if not specified otherwise, accept in input
 | 
			
		||||
a string representing a number, which may contain one of the
 | 
			
		||||
International System number postfixes, for example 'K', 'M', 'G'.
 | 
			
		||||
If 'i' is appended after the postfix, powers of 2 are used instead of
 | 
			
		||||
powers of 10. The 'B' postfix multiplies the value for 8, and can be
 | 
			
		||||
appended after another postfix or used alone. This allows using for
 | 
			
		||||
example 'KB', 'MiB', 'G' and 'B' as postfix.
 | 
			
		||||
 | 
			
		||||
Options which do not take arguments are boolean options, and set the
 | 
			
		||||
corresponding value to true. They can be set to false by prefixing
 | 
			
		||||
with "no" the option name, for example using "-nofoo" in the
 | 
			
		||||
command line will set to false the boolean option with name "foo".

@anchor{Stream specifiers}
 | 
			
		||||
@section Stream specifiers
 | 
			
		||||
Some options are applied per-stream, e.g. bitrate or codec. Stream specifiers
 | 
			
		||||
are used to precisely specify which stream(s) does a given option belong to.
 | 
			
		||||
 | 
			
		||||
A stream specifier is a string generally appended to the option name and
 | 
			
		||||
separated from it by a colon. E.g. @code{-codec:a:1 ac3} option contains
 | 
			
		||||
@code{a:1} stream specifer, which matches the second audio stream. Therefore it
 | 
			
		||||
would select the ac3 codec for the second audio stream.
 | 
			
		||||
 | 
			
		||||
A stream specifier can match several stream, the option is then applied to all
 | 
			
		||||
of them. E.g. the stream specifier in @code{-b:a 128k} matches all audio
 | 
			
		||||
streams.
 | 
			
		||||
 | 
			
		||||
An empty stream specifier matches all streams, for example @code{-codec copy}
 | 
			
		||||
or @code{-codec: copy} would copy all the streams without reencoding.
 | 
			
		||||
 | 
			
		||||
Possible forms of stream specifiers are:
 | 
			
		||||
@table @option
 | 
			
		||||
@item @var{stream_index}
 | 
			
		||||
Matches the stream with this index. E.g. @code{-threads:1 4} would set the
 | 
			
		||||
thread count for the second stream to 4.
 | 
			
		||||
@item @var{stream_type}[:@var{stream_index}]
 | 
			
		||||
@var{stream_type} is one of: 'v' for video, 'a' for audio, 's' for subtitle,
 | 
			
		||||
'd' for data and 't' for attachments. If @var{stream_index} is given, then
 | 
			
		||||
matches stream number @var{stream_index} of this type. Otherwise matches all
 | 
			
		||||
streams of this type.
 | 
			
		||||

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

@subsection Comments
 |

Use the JavaDoc/Doxygen  format (see examples below) so that code documentation

can be generated automatically. All nontrivial functions should have a comment

above them explaining what the function does, even if it is just one sentence.
 | 
			
		||||
All structures and their member variables should be documented, too.
 |

		||||
Avoid Qt-style and similar Doxygen syntax with @code{!} in it, i.e. replace
 | 
			
		||||
@code{//!} with @code{///} and similar.  Also @@ syntax should be employed

@anchor{Regression tests}

@section Regression tests
 | 
			
		||||
 | 
			
		||||
Before submitting a patch (or committing to the repository), you should at least
 | 
			
		||||
test that you did not break anything.
 | 
			
		||||
 | 
			
		||||
Running 'make fate' accomplishes this, please see @url{fate.html} for details.
 | 
			
		||||
The regression tests build a synthetic video stream and a synthetic
 | 
			
		||||
audio stream. These are then encoded and decoded with all codecs or
 | 
			
		||||
formats. The CRC (or MD5) of each generated file is recorded in a
 | 
			
		||||
result file. A 'diff' is launched to compare the reference results and
 | 
			
		||||
the result file. The output is checked immediately after each test
 | 
			
		||||
has run.
 | 
			
		||||
 | 
			
		||||
The regression tests then go on to test the FFserver code with a
 | 
			
		||||
limited set of streams. It is important that this step runs correctly
 | 
			
		||||
as well.
 | 
			
		||||
 | 
			
		||||
Run 'make test' to test all the codecs and formats. Commands like
 | 
			
		||||
'make regtest-mpeg2' can be used to run a single test. By default,
 | 
			
		||||
make will abort if any test fails. To run all tests regardless,
 | 
			
		||||
use make -k. To get a more verbose output, use 'make V=1 test' or
 | 
			
		||||
'make V=2 test'.
 | 
			
		||||
 | 
			
		||||
Run 'make fulltest' to test all the codecs, formats and FFserver.
 | 
			
		||||
 | 
			
		||||
[Of course, some patches may change the results of the regression tests. In
 | 
			
		||||
this case, the reference results of the regression tests shall be modified

@section When will the next FFmpeg version be released? / Why are FFmpeg releases so few and far between?
 | 
			
		||||
 | 
			
		||||
Like most open source projects FFmpeg suffers from a certain lack of
 | 
			
		||||
manpower. For this reason the developers have to prioritize the work
 | 
			
		||||
they do and putting out releases is not at the top of the list, fixing
 | 
			
		||||
bugs and reviewing patches takes precedence. Please don't complain or
 | 
			
		||||
request more timely and/or frequent releases unless you are willing to

help out creating them.

@section I have a problem with an old version of FFmpeg; where should I report it?
 |

Nowhere. We do not support old FFmpeg versions in any way, we simply lack

the time, motivation and manpower to do so. If you have a problem with an
 | 
			
		||||
old version of FFmpeg, upgrade to the latest git snapshot. If you

@section I want CBR, but no matter what I do frame sizes differ.

Short answer: write @option{-profile:v} instead of @option{-profile}.
 | 
			
		||||
You do not understand what CBR is, please read the MPEG spec.
 | 
			
		||||
Read about video buffer verifier and constant bitrate.
 | 
			
		||||
The one sentence summary is that there is a buffer and the input rate is
 | 
			
		||||
constant, the output can vary as needed.
 | 
			
		||||
 | 
			
		||||
Long answer: this happens because the @option{-profile} option can apply to both
 | 
			
		||||
video and audio.  Specifically the AAC encoder also defines some profiles, none
 | 
			
		||||
of which are named @var{baseline}.
 | 
			
		||||
@section How do I check if a stream is CBR?
 | 
			
		||||
 |

The solution is to apply the @option{-profile} option to the video stream only
 | 
			
		||||
by using @url{http://ffmpeg.org/ffmpeg.html#Stream-specifiers-1, Stream specifiers}.
 | 
			
		||||
Appending @code{:v} to it will do exactly that.
 | 
			
		||||
To quote the MPEG-2 spec:
 | 
			
		||||
"There is no way to tell that a bitstream is constant bitrate without

examining all of the vbv_delay values and making complicated computations."

@chapter Introduction
 | 
			
		||||
 | 
			
		||||
  FATE is an extended regression suite on the client-side and a means
 | 
			
		||||
for results aggregation and presentation on the server-side.
 | 
			
		||||
 | 
			
		||||
  The first part of this document explains how you can use FATE from
 | 
			
		||||
your FFmpeg source directory to test your ffmpeg binary. The second
 | 
			
		||||
part describes how you can run FATE to submit the results to FFmpeg's
 | 
			
		||||
FATE server.
 | 
			
		||||
 | 
			
		||||
  In any way you can have a look at the publicly viewable FATE results
 | 
			
		||||
by visiting this website:
 | 
			
		||||
 | 
			
		||||
  @url{http://fate.ffmpeg.org/}
 | 
			
		||||
 | 
			
		||||
  This is especially recommended for all people contributing source
 | 
			
		||||
code to FFmpeg, as it can be seen if some test on some platform broke
 | 
			
		||||
with there recent contribution. This usually happens on the platforms
 | 
			
		||||
the developers could not test on.
 | 
			
		||||
 | 
			
		||||
  The second part of this document describes how you can run FATE to
 | 
			
		||||
submit your results to FFmpeg's FATE server. If you want to submit your
 | 
			
		||||
results be sure to check that your combination of CPU, OS and compiler
 | 
			
		||||
is not already listed on the above mentioned website.
 | 
			
		||||
 | 
			
		||||
  In the third part you can find a comprehensive listing of FATE makefile
 | 
			
		||||
targets and variables.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
@chapter Using FATE from your FFmpeg source directory
 | 
			
		||||
 | 
			
		||||
  If you want to run FATE on your machine you need to have the samples
 | 
			
		||||
in place. You can get the samples via the build target fate-rsync.
 | 
			
		||||
Use this command from the top-level source directory:
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
make fate-rsync SAMPLES=fate-suite/
 | 
			
		||||
make fate       SAMPLES=fate-suite/
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
  The above commands set the samples location by passing a makefile
 | 
			
		||||
variable via command line. It is also possible to set the samples
 | 
			
		||||
location at source configuration time by invoking configure with
 | 
			
		||||
`--samples=<path to the samples directory>'. Afterwards you can
 | 
			
		||||
invoke the makefile targets without setting the SAMPLES makefile
 | 
			
		||||
variable. This is illustrated by the following commands:
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
./configure --samples=fate-suite/
 | 
			
		||||
make fate-rsync
 | 
			
		||||
make fate
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
  Yet another way to tell FATE about the location of the sample
 | 
			
		||||
directory is by making sure the environment variable FATE_SAMPLES
 | 
			
		||||
contains the path to your samples directory. This can be achieved
 | 
			
		||||
by e.g. putting that variable in your shell profile or by setting
 | 
			
		||||
it in your interactive session.
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
FATE_SAMPLES=fate-suite/ make fate
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
@float NOTE
 | 
			
		||||
Do not put a '~' character in the samples path to indicate a home
 | 
			
		||||
directory. Because of shell nuances, this will cause FATE to fail.
 | 
			
		||||
@end float
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
@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
 | 
			
		||||
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:
 | 
			
		||||
 | 
			
		||||
  b1:31:c8:79:3f:04:1d:f8:f2:23:26:5a:fd:55:fa:92
 | 
			
		||||
 | 
			
		||||
  The only thing left is to automate the execution of the fate.sh script and
 | 
			
		||||
the synchronisation of the samples directory.

FATE Automated Testing Environment
 | 
			
		||||
 | 
			
		||||
FATE provides a regression testsuite that can be run locally or configured
 | 
			
		||||
to send reports to fate.ffmpeg.org.
 | 
			
		||||
In order to run, it needs a large amount of data (samples and references)
 | 
			
		||||
that is provided separately from the actual source distribution.
 | 
			
		||||
 | 
			
		||||
Use the following command to get the fate test samples
 | 
			
		||||
 | 
			
		||||
# make fate-rsync SAMPLES=fate-suite/
 | 
			
		||||
 | 
			
		||||
To inform the build system about the testsuite location, pass
 | 
			
		||||
`--samples=<path to the samples>` to configure or set the SAMPLES Make
 | 
			
		||||
variable or the FATE_SAMPLES environment variable to a suitable value.
 | 
			
		||||
 | 
			
		||||

 | 
			
		||||
a live audio/video source. It can also convert between arbitrary sample
 | 
			
		||||
rates and resize video on the fly with a high quality polyphase filter.
 | 
			
		||||
 | 
			
		||||
ffmpeg reads from an arbitrary number of input "files" (which can be regular
 | 
			
		||||
files, pipes, network streams, grabbing devices, etc.), specified by the
 | 
			
		||||
@code{-i} option, and writes to an arbitrary number of output "files", which are
 | 
			
		||||
specified by a plain output filename. Anything found on the command line which
 | 
			
		||||
cannot be interpreted as an option is considered to be an output filename.
 | 
			
		||||
 | 
			
		||||
Each input or output file can in principle contain any number of streams of
 | 
			
		||||
different types (video/audio/subtitle/attachment/data). Allowed number and/or
 | 
			
		||||
types of streams can be limited by the container format. Selecting, which
 | 
			
		||||
streams from which inputs go into output, is done either automatically or with
 | 
			
		||||
the @code{-map} option (see the Stream selection chapter).
 | 
			
		||||
 | 
			
		||||
To refer to input files in options, you must use their indices (0-based). E.g.
 | 
			
		||||
the first input file is @code{0}, the second is @code{1} etc. Similarly, streams
 | 
			
		||||
within a file are referred to by their indices. E.g. @code{2:3} refers to the
 | 
			
		||||
fourth stream in the third input file. See also the Stream specifiers chapter.
 | 
			
		||||
The command line interface is designed to be intuitive, in the sense
 | 
			
		||||
that ffmpeg tries to figure out all parameters that can possibly be
 | 
			
		||||
derived automatically. You usually only have to specify the target
 | 
			
		||||
bitrate you want.
 | 
			
		||||
 | 
			
		||||
As a general rule, options are applied to the next specified
 | 
			
		||||
file. Therefore, order is important, and you can have the same
 | 
			
		||||
option on the command line multiple times. Each occurrence is
 | 
			
		||||
then applied to the next input or output file.
 | 
			
		||||
Exceptions from this rule are the global options (e.g. verbosity level),
 | 
			
		||||
which should be specified first.
 | 
			
		||||
 | 
			
		||||
Do not mix input and output files -- first specify all input files, then all

		||||
output files. Also do not mix options which belong to different files. All

options apply ONLY to the next input or output file and are reset between files.

with the highest resolution, for audio the stream with the most channels, for

 | 
			
		||||
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 re-encoded.
 | 
			
		||||
 | 
			
		||||
For example

 | 
			
		||||
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
 | 
			
		||||
are implemented as a specific type of stream, so this option will add
 | 
			
		||||
a new stream to the file. It is then possible to use per-stream options
 | 
			
		||||
on this stream in the usual way. Attachment streams created with this
 | 
			
		||||
option will be created after all the other streams (i.e. those created
 | 
			
		||||
with @code{-map} or automatic mappings).
 | 
			
		||||
 | 
			
		||||
Note that for Matroska you also have to set the mimetype metadata tag:
 | 
			
		||||
@example
 | 
			
		||||
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).
 | 
			
		||||
 | 
			
		||||
@item -dump_attachment[:@var{stream_specifier}] @var{filename} (@emph{input,per-stream})
 | 
			
		||||
Extract the matching attachment stream into a file named @var{filename}. If
 | 
			
		||||
@var{filename} is empty, then the value of the @code{filename} metadata tag
 | 
			
		||||
will be used.
 | 
			
		||||
 | 
			
		||||
E.g. to extract the first attachment to a file named 'out.ttf':
 | 
			
		||||
@example
 | 
			
		||||
ffmpeg -dump_attachment:t:0 out.ttf INPUT
 | 
			
		||||
@end example
 |

To extract all attachments to files determined by the @code{filename} tag:

@example
 | 
			
		||||
ffmpeg -dump_attachment:t "" INPUT
 | 
			
		||||
@end example
 | 
			
		||||
 |

Technical note -- attachments are implemented as codec extradata, so this

option can actually be used to extract extradata from any stream, not just
 | 
			
		||||
attachments.

If any @code{-map} options are used, the number of @code{-map} options
 | 
			
		||||
on the command line must match the number of streams in the output
 |

the source for output stream 1, etc.
 | 
			
		||||
 | 
			
		||||
A @code{-} character before the stream identifier creates a "negative" mapping.
 | 
			
		||||
It disables matching streams from already created mappings.
 | 
			
		||||
 | 
			
		||||
For example, to map ALL streams from the first input file to output
 | 
			
		||||
@example
 | 
			
		||||
ffmpeg -i INPUT -map 0 output
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
For example, if you have two audio streams in the first input file,
 | 
			
		||||
these streams are identified by "0:0" and "0:1". You can use
 | 
			
		||||
@code{-map} to select which streams to place in an output file. For
 | 
			
		||||
these streams are identified by "0.0" and "0.1". You can use
 | 
			
		||||
@code{-map} to select which stream to place in an output file. For
 | 
			
		||||
example:
 | 
			
		||||
@example
 | 
			
		||||
ffmpeg -i INPUT -map 0:1 out.wav
 | 
			
		||||
ffmpeg -i INPUT out.wav -map 0.1
 | 
			
		||||
@end example
 | 
			
		||||
will map the input stream in @file{INPUT} identified by "0:1" to
 | 
			
		||||
will map the input stream in @file{INPUT} identified by "0.1" to
 | 
			
		||||
the (single) output stream in @file{out.wav}.
 | 
			
		||||
 | 
			
		||||
For example, to select the stream with index 2 from input file
 | 
			
		||||
@file{a.mov} (specified by the identifier "0:2"), and stream with
 | 
			
		||||
index 6 from input @file{b.mov} (specified by the identifier "1:6"),
 | 
			
		||||
@file{a.mov} (specified by the identifier "0.2"), and stream with
 | 
			
		||||
index 6 from input @file{b.mov} (specified by the identifier "1.6"),
 | 
			
		||||
and copy them to the output file @file{out.mov}:
 | 
			
		||||
@example
 | 
			
		||||
ffmpeg -i a.mov -i b.mov -c copy -map 0:2 -map 1:6 out.mov
 | 
			
		||||
ffmpeg -i a.mov -i b.mov -vcodec copy -acodec copy out.mov -map 0.2 -map 1.6
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
To select all video and the third audio stream from an input file:
 | 
			
		||||
@example
 | 
			
		||||
ffmpeg -i INPUT -map 0:v -map 0:a:2 OUTPUT
 | 
			
		||||
@end example
 | 
			
		||||
To add more streams to the output file, you can use the
 | 
			
		||||
@code{-newaudio}, @code{-newvideo}, @code{-newsubtitle} options.
 | 
			
		||||
 | 
			
		||||
To map all the streams except the second audio, use negative mappings
 | 
			
		||||
@example
 | 
			
		||||
ffmpeg -i INPUT -map 0 -map -0:a:1 OUTPUT
 | 
			
		||||
@end example
 |

@item -map_meta_data @var{outfile}[,@var{metadata}]:@var{infile}[,@var{metadata}]
 |

Deprecated, use @var{-map_metadata} instead.
 |

 | 
			
		||||
Note that using this option disables the default mappings for this output file.
 | 
			
		||||
@item -map_metadata @var{outfile}[,@var{metadata}]:@var{infile}[,@var{metadata}]
 | 
			
		||||
Set metadata information of @var{outfile} from @var{infile}. Note that those
 | 
			
		||||
are file indices (zero-based), not filenames.
 | 
			
		||||
Optional @var{metadata} parameters specify, which metadata to copy - (g)lobal
 | 
			
		||||
(i.e. metadata that applies to the whole file), per-(s)tream, per-(c)hapter or
 | 
			
		||||
per-(p)rogram. All metadata specifiers other than global must be followed by the
 | 
			
		||||
stream/chapter/program number. If metadata specifier is omitted, it defaults to
 | 
			
		||||
global.
 | 
			
		||||
 | 
			
		||||
@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} are 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
 | 
			
		||||
channel layouts don't match (for instance two "-map_channel" options and "-ac
 | 
			
		||||
6").
 | 
			
		||||
 | 
			
		||||
You can also extract each channel of an @var{INPUT} to specific outputs; the
 | 
			
		||||
following command extract each channel of the audio stream (file 0, stream 0)
 | 
			
		||||
to the respective @var{OUTPUT_CH0} and @var{OUTPUT_CH1}:
 | 
			
		||||
@example
 | 
			
		||||
ffmpeg -i INPUT -map_channel 0.0.0 OUTPUT_CH0 -map_channel 0.0.1 OUTPUT_CH1
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
The following example split the channels of a stereo input into streams:
 | 
			
		||||
 | 
			
		||||
@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 spliting a stereo stream into two single channel mono streams
 | 
			
		||||
is possible.

All the numerical options, if not specified otherwise, accept in input
 | 
			
		||||
a string representing a number, which may contain one of the
 | 
			
		||||
International System number postfixes, for example 'K', 'M', 'G'.
 | 
			
		||||
If 'i' is appended after the postfix, powers of 2 are used instead of
 | 
			
		||||
powers of 10. The 'B' postfix multiplies the value for 8, and can be
 | 
			
		||||
appended after another postfix or used alone. This allows using for
 | 
			
		||||
example 'KB', 'MiB', 'G' and 'B' as postfix.
 | 
			
		||||
 | 
			
		||||
Options which do not take arguments are boolean options, and set the
 | 
			
		||||
corresponding value to true. They can be set to false by prefixing
 | 
			
		||||
with "no" the option name, for example using "-nofoo" in the

commandline will set to false the boolean option with name "foo".

@chapter Platform Specific information
 |

 | 
			
		||||
@section DOS
 | 
			
		||||
 | 
			
		||||
Using a cross-compiler is preferred for various reasons.
 | 
			
		||||
 | 
			
		||||
@section OS/2
 | 
			
		||||
 | 
			
		||||
For information about compiling FFmpeg on OS/2 see
 | 
			
		||||
@url{http://www.edm2.com/index.php/FFmpeg}.
 | 
			
		||||
 | 
			
		||||
@section Unix-like
 | 
			
		||||
 | 
			
		||||
Some parts of FFmpeg cannot be built with version 2.15 of the GNU
 | 
			
		||||
assembler which is still provided by a few AMD64 distributions. To
 | 
			
		||||
make sure your compiler really uses the required version of gas
 | 
			
		||||
after a binutils upgrade, run:
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
$(gcc -print-prog-name=as) --version
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
If not, then you should install a different compiler that has no
 | 
			
		||||
hard-coded path to gas. In the worst case pass @code{--disable-asm}
 | 
			
		||||
to configure.
 | 
			
		||||
 | 
			
		||||
@subsection BSD
 | 
			
		||||
 | 
			
		||||
BSD make will not build FFmpeg, you need to install and use GNU Make
 | 
			
		||||
(@file{gmake}).
 | 
			
		||||
 | 
			
		||||
@subsection (Open)Solaris
 | 
			
		||||
 | 
			
		||||
GNU Make is required to build FFmpeg, so you have to invoke (@file{gmake}),
 | 
			
		||||
standard Solaris Make will not work. When building with a non-c99 front-end
 | 
			
		||||
(gcc, generic suncc) add either @code{--extra-libs=/usr/lib/values-xpg6.o}
 | 
			
		||||
or @code{--extra-libs=/usr/lib/64/values-xpg6.o} to the configure options
 | 
			
		||||
since the libc is not c99-compliant by default. The probes performed by
 | 
			
		||||
configure may raise an exception leading to the death of configure itself
 | 
			
		||||
due to a bug in the system shell. Simply invoke a different shell such as
 | 
			
		||||
bash directly to work around this:
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
bash ./configure
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
@subsection Darwin (MacOS X, iPhone)
 | 
			
		||||
 | 
			
		||||
MacOS X on PowerPC or ARM (iPhone) requires a preprocessor from
 | 
			
		||||
@url{http://github.com/yuvi/gas-preprocessor} to build the optimized
 | 
			
		||||
assembler functions. Just download the Perl script and put it somewhere
 | 
			
		||||
in your PATH, FFmpeg's configure will pick it up automatically.

@section Windows
 | 
			
		||||
 | 
			
		||||
To get help and instructions for building FFmpeg under Windows, check out
 |

@subsection Native Windows compilation
 | 
			
		||||
 | 
			
		||||
FFmpeg can be built to run natively on Windows using the MinGW tools. Install
 | 
			
		||||
the latest versions of MSYS and MinGW from @url{http://www.mingw.org/}.
 | 
			
		||||
You can find detailed installation
 | 
			
		||||
instructions in the download section and the FAQ.
 | 
			
		||||
 | 
			
		||||
FFmpeg does not build out-of-the-box with the packages the automated MinGW
 | 
			
		||||
installer provides. It also requires coreutils to be installed and many other
 | 
			
		||||
packages updated to the latest version. The minimum version for some packages
 | 
			
		||||
are listed below:
 | 
			
		||||
 | 
			
		||||
@itemize
 | 
			
		||||
@item bash 3.1
 | 
			
		||||
@item msys-make 3.81-2 (note: not mingw32-make)
 | 
			
		||||
@item w32api 3.13
 | 
			
		||||
@item mingw-runtime 3.15
 | 
			
		||||
@end itemize
 | 
			
		||||
 | 
			
		||||
FFmpeg automatically passes @code{-fno-common} to the compiler to work around
 | 
			
		||||
a GCC bug (see @url{http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37216}).
 | 
			
		||||
 | 
			
		||||
Notes:
 | 
			
		||||
 | 
			
		||||
@itemize
 | 
			
		||||
 | 
			
		||||
@item Building natively using MSYS can be sped up by disabling implicit rules
 | 
			
		||||
in the Makefile by calling @code{make -r} instead of plain @code{make}. This
 | 
			
		||||
speed up is close to non-existent for normal one-off builds and is only
 | 
			
		||||
noticeable when running make for a second time (for example in
 | 
			
		||||
@code{make install}).
 | 
			
		||||
 | 
			
		||||
@item In order to compile FFplay, you must have the MinGW development library
 | 
			
		||||
of SDL. Get it from @url{http://www.libsdl.org}.
 | 
			
		||||
Edit the @file{bin/sdl-config} script so that it points to the correct prefix
 | 
			
		||||
where SDL was installed. Verify that @file{sdl-config} can be launched from
 | 
			
		||||
the MSYS command line.
 | 
			
		||||
 | 
			
		||||
@item By using @code{./configure --enable-shared} when configuring FFmpeg,
 | 
			
		||||
you can build libavutil, libavcodec and libavformat as DLLs.
 | 
			
		||||
 | 
			
		||||

		||||
@subsection Microsoft Visual C++ compatibility
 | 
			
		||||
 | 
			
		||||
As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
 | 
			
		||||
want to use the libav* libraries in your own applications, you can still
 | 
			
		||||
compile those applications using MSVC++. But the libav* libraries you link
 | 
			
		||||
to @emph{must} be built with MinGW. However, you will not be able to debug
 | 
			
		||||
inside the libav* libraries, since MSVC++ does not recognize the debug
 | 
			
		||||
symbols generated by GCC.
 | 
			
		||||
We strongly recommend you to move over from MSVC++ to MinGW tools.
 | 
			
		||||
 | 
			
		||||
This description of how to use the FFmpeg libraries with MSVC++ is based on
 | 
			
		||||
Microsoft Visual C++ 2005 Express Edition. If you have a different version,
 | 
			
		||||
you might have to modify the procedures slightly.
 | 
			
		||||
 | 
			
		||||
@subsubsection Using static libraries
 | 
			
		||||
 | 
			
		||||
Assuming you have just built and installed FFmpeg in @file{/usr/local}.
 | 
			
		||||
 | 
			
		||||
@enumerate
 | 
			
		||||
 | 
			
		||||
@item Create a new console application ("File / New / Project") and then
 | 
			
		||||
select "Win32 Console Application". On the appropriate page of the
 | 
			
		||||
Application Wizard, uncheck the "Precompiled headers" option.
 | 
			
		||||
 | 
			
		||||
@item Write the source code for your application, or, for testing, just
 | 
			
		||||
copy the code from an existing sample application into the source file
 | 
			
		||||
that MSVC++ has already created for you. For example, you can copy
 | 
			
		||||
@file{libavformat/output-example.c} from the FFmpeg distribution.
 | 
			
		||||
 | 
			
		||||
@item Open the "Project / Properties" dialog box. In the "Configuration"
 | 
			
		||||
combo box, select "All Configurations" so that the changes you make will
 | 
			
		||||
affect both debug and release builds. In the tree view on the left hand
 | 
			
		||||
side, select "C/C++ / General", then edit the "Additional Include
 | 
			
		||||
Directories" setting to contain the path where the FFmpeg includes were
 | 
			
		||||
installed (i.e. @file{c:\msys\1.0\local\include}).
 | 
			
		||||
Do not add MinGW's include directory here, or the include files will
 | 
			
		||||
conflict with MSVC's.
 | 
			
		||||
 | 
			
		||||
@item Still in the "Project / Properties" dialog box, select
 | 
			
		||||
"Linker / General" from the tree view and edit the
 | 
			
		||||
"Additional Library Directories" setting to contain the @file{lib}
 | 
			
		||||
directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
 | 
			
		||||
the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
 | 
			
		||||
and the directory where MinGW's GCC libs are installed
 | 
			
		||||
(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
 | 
			
		||||
"Linker / Input" from the tree view, and add the files @file{libavformat.a},
 | 
			
		||||
@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
 | 
			
		||||
@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
 | 
			
		||||
to the end of "Additional Dependencies".
 | 
			
		||||
 | 
			
		||||
@item Now, select "C/C++ / Code Generation" from the tree view. Select
 | 
			
		||||
"Debug" in the "Configuration" combo box. Make sure that "Runtime
 | 
			
		||||
Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
 | 
			
		||||
the "Configuration" combo box and make sure that "Runtime Library" is
 | 
			
		||||
set to "Multi-threaded DLL".
 | 
			
		||||
 | 
			
		||||
@item Click "OK" to close the "Project / Properties" dialog box.
 | 
			
		||||
 | 
			
		||||
@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
 | 
			
		||||
Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
 | 
			
		||||
and install it in MSVC++'s include directory
 | 
			
		||||
(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
 | 
			
		||||
 | 
			
		||||
@item MSVC++ also does not understand the @code{inline} keyword used by
 | 
			
		||||
FFmpeg, so you must add this line before @code{#include}ing libav*:
 | 
			
		||||
@example
 | 
			
		||||
#define inline _inline
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
@item Build your application, everything should work.
 | 
			
		||||
 | 
			
		||||
@end enumerate
 | 
			
		||||
 | 
			
		||||
@subsubsection Using shared libraries
 | 
			
		||||
 | 
			
		||||
This is how to create DLL and LIB files that are compatible with MSVC++:
 | 
			
		||||
 | 
			
		||||
@enumerate
 | 
			
		||||
 | 
			
		||||
@item Add a call to @file{vcvars32.bat} (which sets up the environment
 | 
			
		||||
variables for the Visual C++ tools) as the first line of @file{msys.bat}.
 | 
			
		||||
The standard location for @file{vcvars32.bat} is
 | 
			
		||||
@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
 | 
			
		||||
and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
 | 
			
		||||
If this corresponds to your setup, add the following line as the first line
 | 
			
		||||
of @file{msys.bat}:
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
 | 
			
		||||
and run @file{c:\msys\1.0\msys.bat} from there.
 | 
			
		||||
 | 
			
		||||
@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
 | 
			
		||||
from @file{Microsoft (R) Library Manager}, this means your environment
 | 
			
		||||
variables are set up correctly, the @file{Microsoft (R) Library Manager}
 | 
			
		||||
is on the path and will be used by FFmpeg to create
 | 
			
		||||
MSVC++-compatible import libraries.
 | 
			
		||||
 | 
			
		||||
@item Build FFmpeg with
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
./configure --enable-shared
 | 
			
		||||
make
 | 
			
		||||
make install
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
Your install path (@file{/usr/local/} by default) should now have the
 | 
			
		||||
necessary DLL and LIB files under the @file{bin} directory.
 | 
			
		||||
 | 
			
		||||
@end enumerate
 | 
			
		||||
 | 
			
		||||
To use those files with MSVC++, do the same as you would do with
 | 
			
		||||
the static libraries, as described above. But in Step 4,
 | 
			
		||||
you should only need to add the directory where the LIB files are installed
 | 
			
		||||
(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
 | 
			
		||||
installed in the @file{bin} directory. And instead of adding the static
 | 
			
		||||
libraries (@file{libxxx.a} files) you should add the MSVC import libraries
 | 
			
		||||
(@file{avcodec.lib}, @file{avformat.lib}, and
 | 
			
		||||
@file{avutil.lib}). Note that you should not use the GCC import
 | 
			
		||||
libraries (@file{libxxx.dll.a} files), as these will give you undefined
 | 
			
		||||
reference errors. There should be no need for @file{libmingwex.a},
 | 
			
		||||
@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
 | 
			
		||||
statically linked into the DLLs. The @file{bin} directory contains a bunch
 | 
			
		||||
of DLL files, but the ones that are actually used to run your application
 | 
			
		||||
are the ones with a major version number in their filenames
 | 
			
		||||
(i.e. @file{avcodec-51.dll}).
 | 
			
		||||
 | 
			
		||||
FFmpeg headers do not declare global data for Windows DLLs through the usual
 | 
			
		||||
dllexport/dllimport interface. Such data will be exported properly while
 | 
			
		||||
building, but to use them in your MSVC++ code you will have to edit the
 | 
			
		||||
appropriate headers and mark the data as dllimport. For example, in
 | 
			
		||||
libavutil/pixdesc.h you should have:
 | 
			
		||||
@example
 | 
			
		||||
extern __declspec(dllimport) const AVPixFmtDescriptor av_pix_fmt_descriptors[];
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
Note that using import libraries created by dlltool requires
 | 
			
		||||
the linker optimization option to be set to
 | 
			
		||||
"References: Keep Unreferenced Data (@code{/OPT:NOREF})", otherwise
 | 
			
		||||
the resulting binaries will fail during runtime. This isn't
 | 
			
		||||
required when using import libraries generated by lib.exe.
 | 
			
		||||
This issue is reported upstream at
 | 
			
		||||
@url{http://sourceware.org/bugzilla/show_bug.cgi?id=12633}.
 | 
			
		||||
 | 
			
		||||
@subsection Cross compilation for Windows with Linux
 | 
			
		||||
 | 
			
		||||
You must use the MinGW cross compilation tools available at
 | 
			
		||||
@url{http://www.mingw.org/}.
 | 
			
		||||
 | 
			
		||||
Then configure FFmpeg with the following options:
 | 
			
		||||
@example
 | 
			
		||||
./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
 | 
			
		||||
@end example
 | 
			
		||||
(you can change the cross-prefix according to the prefix chosen for the
 | 
			
		||||
MinGW tools).
 | 
			
		||||
 | 
			
		||||
Then you can easily test FFmpeg with Wine
 | 
			
		||||
(@url{http://www.winehq.com/}).
 | 
			
		||||
 | 
			
		||||
@subsection Compilation under Cygwin
 | 
			
		||||
 | 
			
		||||
Please use Cygwin 1.7.x as the obsolete 1.5.x Cygwin versions lack
 | 
			
		||||
llrint() in its C library.
 | 
			
		||||
 | 
			
		||||
Install your Cygwin with all the "Base" packages, plus the
 | 
			
		||||
following "Devel" ones:
 | 
			
		||||
@example
 | 
			
		||||
binutils, gcc4-core, make, git, mingw-runtime, texi2html
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
And the following "Utils" one:
 | 
			
		||||
@example
 | 
			
		||||
diffutils
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
Then run
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
./configure
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
to make a static build.
 | 
			
		||||
 | 
			
		||||
The current @code{gcc4-core} package is buggy and needs this flag to build
 | 
			
		||||
shared libraries:
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
./configure --enable-shared --disable-static --extra-cflags=-fno-reorder-functions
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
If you want to build FFmpeg with additional libraries, download Cygwin
 | 
			
		||||
"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
 | 
			
		||||
@example
 | 
			
		||||
libogg-devel, libvorbis-devel
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
These library packages are only available from Cygwin Ports
 | 
			
		||||
(@url{http://sourceware.org/cygwinports/}) :
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
yasm, libSDL-devel, libdirac-devel, libfaac-devel, libgsm-devel,
 | 
			
		||||
libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
 | 
			
		||||
libxvidcore-devel
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
The recommendation for libnut and x264 is to build them from source by
 | 
			
		||||
yourself, as they evolve too quickly for Cygwin Ports to be up to date.
 | 
			
		||||
 | 
			
		||||
Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
 | 
			
		||||
of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.
 | 
			
		||||
 | 
			
		||||
@subsection Crosscompilation for Windows under Cygwin
 | 
			
		||||
 | 
			
		||||
With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
 | 
			
		||||
 | 
			
		||||
Just install your Cygwin as explained before, plus these additional
 | 
			
		||||
"Devel" packages:
 | 
			
		||||
@example
 | 
			
		||||
gcc-mingw-core, mingw-runtime, mingw-zlib
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
and add some special flags to your configure invocation.
 | 
			
		||||
 | 
			
		||||
For a static build run
 | 
			
		||||
@example
 | 
			
		||||
./configure --target-os=mingw32 --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
and for a build with shared libraries
 | 
			
		||||
@example
 | 
			
		||||
./configure --target-os=mingw32 --enable-shared --disable-static --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin
 | 
			
		||||
@end example
 | 
			
		||||

@chapter Introduction
 | 
			
		||||
 | 
			
		||||
This document aims in giving some quick references on a set of useful git
 | 
			
		||||
commands. You should always use the extensive and detailed documentation
 | 
			
		||||
provided directly by git:
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git --help
 | 
			
		||||
man git
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
shows you the available subcommands,
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git <command> --help
 | 
			
		||||
man git-<command>
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
shows information about the subcommand <command>.
 | 
			
		||||
 | 
			
		||||
Additional information could be found on the
 | 
			
		||||
@url{http://gitref.org, Git Reference} website
 | 
			
		||||
 | 
			
		||||
For more information about the Git project, visit the
 | 
			
		||||
 | 
			
		||||
@url{http://git-scm.com/, Git website}
 | 
			
		||||
 | 
			
		||||
Consult these resources whenever you have problems, they are quite exhaustive.
 | 
			
		||||
 | 
			
		||||
What follows now is a basic introduction to Git and some FFmpeg-specific
 | 
			
		||||
guidelines to ease the contribution to the project
 | 
			
		||||
 | 
			
		||||
@chapter Basics Usage
 | 
			
		||||
 | 
			
		||||
@section Get GIT
 | 
			
		||||
 | 
			
		||||
You can get git from @url{http://git-scm.com/}
 | 
			
		||||
Most distribution and operating system provide a package for it.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
@section Cloning the source tree
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git clone git://source.ffmpeg.org/ffmpeg <target>
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
This will put the FFmpeg sources into the directory @var{<target>}.
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git clone git@@source.ffmpeg.org:ffmpeg <target>
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
This will put the FFmpeg sources into the directory @var{<target>} and let
 | 
			
		||||
you push back your changes to the remote repository.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
@section Updating the source tree to the latest revision
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git pull (--rebase)
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
pulls in the latest changes from the tracked branch. The tracked branch
 | 
			
		||||
can be remote. By default the master branch tracks the branch master in
 | 
			
		||||
the remote origin.
 | 
			
		||||
 | 
			
		||||
@float IMPORTANT
 | 
			
		||||
@command{--rebase} (see below) is recommended.
 | 
			
		||||
@end float
 | 
			
		||||
 | 
			
		||||
@section Rebasing your local branches
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git pull --rebase
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
fetches the changes from the main repository and replays your local commits
 | 
			
		||||
over it. This is required to keep all your local changes at the top of
 | 
			
		||||
FFmpeg's master tree. The master tree will reject pushes with merge commits.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
@section Adding/removing files/directories
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||

GIT needs to get notified of all changes you make to your working
 | 
			
		||||
directory that makes files appear or disappear.
 | 
			
		||||
Line moves across files are automatically tracked.

@section Showing modifications
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git diff <filename(s)>
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
will show all local modifications in your working directory as unified diff.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
@section Inspecting the changelog
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git log <filename(s)>
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
You may also use the graphical tools like gitview or gitk or the web
 | 
			
		||||
interface available at http://source.ffmpeg.org/
 | 
			
		||||
 | 
			
		||||
@section Checking source tree status
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git status
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
detects all the changes you made and lists what actions will be taken in case
 | 
			
		||||
of a commit (additions, modifications, deletions, etc.).
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
@section Committing
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git diff --check
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
to double check your changes before committing them to avoid trouble later
 | 
			
		||||
on. All experienced developers do this on each and every commit, no matter
 | 
			
		||||
how small.
 | 
			
		||||
Every one of them has been saved from looking like a fool by this many times.
 | 
			
		||||
It's very easy for stray debug output or cosmetic modifications to slip in,
 | 
			
		||||
please avoid problems through this extra level of scrutiny.
 | 
			
		||||
 | 
			
		||||
For cosmetics-only commits you should get (almost) empty output from
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git diff -w -b <filename(s)>
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
Also check the output of
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git status
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
to make sure you don't have untracked files or deletions.
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git add [-i|-p|-A] <filenames/dirnames>
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
Make sure you have told git your name and email address
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git config --global user.name "My Name"
 | 
			
		||||
git config --global user.email my@@email.invalid
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
Use @var{--global} to set the global configuration for all your git checkouts.
 | 
			
		||||
 | 
			
		||||
Git will select the changes to the files for commit. Optionally you can use
 | 
			
		||||
the interactive or the patch mode to select hunk by hunk what should be
 | 
			
		||||
added to the commit.
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git commit
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
Git will commit the selected changes to your current local branch.
 | 
			
		||||
 | 
			
		||||
You will be prompted for a log message in an editor, which is either
 | 
			
		||||
set in your personal configuration file through
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git config --global core.editor
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
or set by one of the following environment variables:
 | 
			
		||||
@var{GIT_EDITOR}, @var{VISUAL} or @var{EDITOR}.
 | 
			
		||||
 | 
			
		||||
Log messages should be concise but descriptive. Explain why you made a change,
 | 
			
		||||
what you did will be obvious from the changes themselves most of the time.
 | 
			
		||||
Saying just "bug fix" or "10l" is bad. Remember that people of varying skill
 | 
			
		||||
levels look at and educate themselves while reading through your code. Don't
 | 
			
		||||
include filenames in log messages, Git provides that information.
 | 
			
		||||
 | 
			
		||||
Possibly make the commit message have a terse, descriptive first line, an
 | 
			
		||||
empty line and then a full description. The first line will be used to name
 | 
			
		||||
the patch by git format-patch.
 | 
			
		||||
 | 
			
		||||
@section Preparing a patchset
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git format-patch <commit> [-o directory]
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
will generate a set of patches for each commit between @var{<commit>} and
 | 
			
		||||
current @var{HEAD}. E.g.
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git format-patch origin/master
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
will generate patches for all commits on current branch which are not
 | 
			
		||||
present in upstream.
 | 
			
		||||
A useful shortcut is also
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git format-patch -n
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
which will generate patches from last @var{n} commits.
 | 
			
		||||
By default the patches are created in the current directory.
 | 
			
		||||
 | 
			
		||||
@section Sending patches for review
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git send-email <commit list|directory>
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
will send the patches created by @command{git format-patch} or directly
 | 
			
		||||
generates them. All the email fields can be configured in the global/local
 | 
			
		||||
configuration or overridden by command line.
 | 
			
		||||
Note that this tool must often be installed separately (e.g. @var{git-email}
 | 
			
		||||
package on Debian-based distros).
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
@section Renaming/moving/copying files or contents of files
 | 
			
		||||
 | 
			
		||||
Git automatically tracks such changes, making those normal commits.
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
mv/cp path/file otherpath/otherfile
 | 
			
		||||
git add [-A] .
 | 
			
		||||
git commit
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
 | 
			
		||||
@chapter FFmpeg specific
 | 
			
		||||
 | 
			
		||||
@section Reverting broken commits
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git reset <commit>
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
@command{git reset} will uncommit the changes till @var{<commit>} rewriting
 | 
			
		||||
the current branch history.
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git commit --amend
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
allows to amend the last commit details quickly.
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git rebase -i origin/master
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
will replay local commits over the main repository allowing to edit, merge
 | 
			
		||||
or remove some of them in the process.
 | 
			
		||||
 | 
			
		||||
@float NOTE
 | 
			
		||||
@command{git reset}, @command{git commit --amend} and @command{git rebase}
 | 
			
		||||
rewrite history, so you should use them ONLY on your local or topic branches.
 | 
			
		||||
The main repository will reject those changes.
 | 
			
		||||
@end float
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git revert <commit>
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
@command{git revert} will generate a revert commit. This will not make the
 | 
			
		||||
faulty commit disappear from the history.
 | 
			
		||||
 | 
			
		||||
@section Pushing changes to remote trees
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git push
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
Will push the changes to the default remote (@var{origin}).
 | 
			
		||||
Git will prevent you from pushing changes if the local and remote trees are
 | 
			
		||||
out of sync. Refer to and to sync the local tree.
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git remote add <name> <url>
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
Will add additional remote with a name reference, it is useful if you want
 | 
			
		||||
to push your local branch for review on a remote host.
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git push <remote> <refspec>
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
Will push the changes to the @var{<remote>} repository.
 | 
			
		||||
Omitting @var{<refspec>} makes @command{git push} update all the remote
 | 
			
		||||
branches matching the local ones.
 | 
			
		||||
 | 
			
		||||
@section Finding a specific svn revision
 | 
			
		||||
 | 
			
		||||
Since version 1.7.1 git supports @var{:/foo} syntax for specifying commits
 | 
			
		||||
based on a regular expression. see man gitrevisions
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git show :/'as revision 23456'
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
will show the svn changeset @var{r23456}. With older git versions searching in
 | 
			
		||||
the @command{git log} output is the easiest option (especially if a pager with
 | 
			
		||||
search capabilities is used).
 | 
			
		||||
This commit can be checked out with
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git checkout -b svn_23456 :/'as revision 23456'
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
or for git < 1.7.1 with
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
git checkout -b svn_23456 $SHA1
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
where @var{$SHA1} is the commit hash from the @command{git log} output.

This input device reads data from the open output pads of a libavfilter
 | 
			
		||||
filtergraph.
 | 
			
		||||
 | 
			
		||||
For each filtergraph open output, the input device will create a
 | 
			
		||||
corresponding stream which is mapped to the generated output. Currently
 | 
			
		||||
only video data is supported. The filtergraph is specified through the
 | 
			
		||||
option @option{graph}.

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.

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.

Some parts of FFmpeg cannot be built with version 2.15 of the GNU
 | 
			
		||||
assembler which is still provided by a few AMD64 distributions. To
 | 
			
		||||
make sure your compiler really uses the required version of gas
 | 
			
		||||
after a binutils upgrade, run:
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
$(gcc -print-prog-name=as) --version
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
If not, then you should install a different compiler that has no
 | 
			
		||||
hard-coded path to gas. In the worst case pass @code{--disable-asm}
 | 
			
		||||
to configure.

@section BSD

@section (Open)Solaris
 | 
			
		||||
 | 
			
		||||
GNU Make is required to build FFmpeg, so you have to invoke (@file{gmake}),
 | 
			
		||||
standard Solaris Make will not work. When building with a non-c99 front-end
 | 
			
		||||
(gcc, generic suncc) add either @code{--extra-libs=/usr/lib/values-xpg6.o}
 | 
			
		||||
or @code{--extra-libs=/usr/lib/64/values-xpg6.o} to the configure options
 | 
			
		||||
since the libc is not c99-compliant by default. The probes performed by
 | 
			
		||||
configure may raise an exception leading to the death of configure itself
 | 
			
		||||
due to a bug in the system shell. Simply invoke a different shell such as
 | 
			
		||||
bash directly to work around this:
 | 
			
		||||
 | 
			
		||||

 | 
			
		||||

@section Native Windows compilation
 | 
			
		||||
 | 
			
		||||
FFmpeg can be built to run natively on Windows using the MinGW tools. Install
 | 
			
		||||
the latest versions of MSYS and MinGW from @url{http://www.mingw.org/}.
 | 
			
		||||
You can find detailed installation instructions in the download
 | 
			
		||||
section and the FAQ.
 | 
			
		||||
 | 
			
		||||
FFmpeg does not build out-of-the-box with the packages the automated MinGW
 | 
			
		||||
installer provides. It also requires coreutils to be installed and many other
 | 
			
		||||
packages updated to the latest version. The minimum version for some packages
 | 
			
		||||
are listed below:
 | 
			
		||||
 | 
			
		||||
@itemize
 | 
			
		||||
@item bash 3.1
 | 
			
		||||
@item msys-make 3.81-2 (note: not mingw32-make)

		||||
@item mingw-runtime 3.15
 |

@end itemize
 |

FFmpeg automatically passes @code{-fno-common} to the compiler to work around
 | 
			
		||||
a GCC bug (see @url{http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37216}).
 |

 | 
			
		||||
Notes:
 | 
			
		||||
 | 
			
		||||
@itemize
 | 
			
		||||
 | 
			
		||||
@item Building natively using MSYS can be sped up by disabling implicit rules
 | 
			
		||||
in the Makefile by calling @code{make -r} instead of plain @code{make}. This
 | 
			
		||||
speed up is close to non-existent for normal one-off builds and is only
 | 
			
		||||
noticeable when running make for a second time (for example in
 | 
			
		||||
@code{make install}).
 | 
			
		||||
 | 
			
		||||
@item In order to compile FFplay, you must have the MinGW development library
 | 
			
		||||
of @uref{http://www.libsdl.org/, SDL}.
 | 
			
		||||
Edit the @file{bin/sdl-config} script so that it points to the correct prefix
 | 
			
		||||
where SDL was installed. Verify that @file{sdl-config} can be launched from
 | 
			
		||||
the MSYS command line.
 | 
			
		||||
 | 
			
		||||
@item By using @code{./configure --enable-shared} when configuring FFmpeg,
 | 
			
		||||
you can build the FFmpeg libraries (e.g. libavutil, libavcodec,
 | 
			
		||||
libavformat) as DLLs.

@section Microsoft Visual C++ compatibility
 | 
			
		||||
 | 
			
		||||
As stated in the FAQ, FFmpeg will not compile under MSVC++. However, if you
 | 
			
		||||
want to use the libav* libraries in your own applications, you can still
 | 
			
		||||
compile those applications using MSVC++. But the libav* libraries you link
 | 
			
		||||
to @emph{must} be built with MinGW. However, you will not be able to debug
 | 
			
		||||
inside the libav* libraries, since MSVC++ does not recognize the debug
 | 
			
		||||
symbols generated by GCC.
 | 
			
		||||
We strongly recommend you to move over from MSVC++ to MinGW tools.
 | 
			
		||||
 | 
			
		||||
This description of how to use the FFmpeg libraries with MSVC++ is based on
 | 
			
		||||
Microsoft Visual C++ 2005 Express Edition. If you have a different version,
 | 
			
		||||
you might have to modify the procedures slightly.
 | 
			
		||||
 | 
			
		||||
@subsection Using static libraries
 | 
			
		||||
 | 
			
		||||
Assuming you have just built and installed FFmpeg in @file{/usr/local}.
 | 
			
		||||
 | 
			
		||||
@enumerate
 | 
			
		||||
 | 
			
		||||
@item Create a new console application ("File / New / Project") and then
 | 
			
		||||
select "Win32 Console Application". On the appropriate page of the
 | 
			
		||||
Application Wizard, uncheck the "Precompiled headers" option.
 | 
			
		||||
 | 
			
		||||
@item Write the source code for your application, or, for testing, just
 | 
			
		||||
copy the code from an existing sample application into the source file
 | 
			
		||||
that MSVC++ has already created for you. For example, you can copy
 | 
			
		||||
@file{libavformat/output-example.c} from the FFmpeg distribution.
 | 
			
		||||
 | 
			
		||||
@item Open the "Project / Properties" dialog box. In the "Configuration"
 | 
			
		||||
combo box, select "All Configurations" so that the changes you make will
 | 
			
		||||
affect both debug and release builds. In the tree view on the left hand
 | 
			
		||||
side, select "C/C++ / General", then edit the "Additional Include
 | 
			
		||||
Directories" setting to contain the path where the FFmpeg includes were
 | 
			
		||||
installed (i.e. @file{c:\msys\1.0\local\include}).
 | 
			
		||||
Do not add MinGW's include directory here, or the include files will
 | 
			
		||||
conflict with MSVC's.
 | 
			
		||||
 | 
			
		||||
@item Still in the "Project / Properties" dialog box, select
 | 
			
		||||
"Linker / General" from the tree view and edit the
 | 
			
		||||
"Additional Library Directories" setting to contain the @file{lib}
 | 
			
		||||
directory where FFmpeg was installed (i.e. @file{c:\msys\1.0\local\lib}),
 | 
			
		||||
the directory where MinGW libs are installed (i.e. @file{c:\mingw\lib}),
 | 
			
		||||
and the directory where MinGW's GCC libs are installed
 | 
			
		||||
(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
 | 
			
		||||
"Linker / Input" from the tree view, and add the files @file{libavformat.a},
 | 
			
		||||
@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
 | 
			
		||||
@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})
 | 
			
		||||
to the end of "Additional Dependencies".
 | 
			
		||||
 | 
			
		||||
@item Now, select "C/C++ / Code Generation" from the tree view. Select
 | 
			
		||||
"Debug" in the "Configuration" combo box. Make sure that "Runtime
 | 
			
		||||
Library" is set to "Multi-threaded Debug DLL". Then, select "Release" in
 | 
			
		||||
the "Configuration" combo box and make sure that "Runtime Library" is
 | 
			
		||||
set to "Multi-threaded DLL".
 | 
			
		||||
 | 
			
		||||
@item Click "OK" to close the "Project / Properties" dialog box.
 | 
			
		||||
 | 
			
		||||
@item MSVC++ lacks some C99 header files that are fundamental for FFmpeg.
 | 
			
		||||
Get msinttypes from @url{http://code.google.com/p/msinttypes/downloads/list}
 | 
			
		||||
and install it in MSVC++'s include directory
 | 
			
		||||
(i.e. @file{C:\Program Files\Microsoft Visual Studio 8\VC\include}).
 | 
			
		||||
 | 
			
		||||
@item MSVC++ also does not understand the @code{inline} keyword used by
 | 
			
		||||
FFmpeg, so you must add this line before @code{#include}ing libav*:
 | 
			
		||||
@example
 | 
			
		||||
#define inline _inline
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
@item Build your application, everything should work.
 | 
			
		||||
 | 
			
		||||
@end enumerate
 | 
			
		||||
 | 
			
		||||
@subsection Using shared libraries
 | 
			
		||||
 | 
			
		||||
This is how to create DLL and LIB files that are compatible with MSVC++:
 | 
			
		||||
 | 
			
		||||
@enumerate
 | 
			
		||||
 | 
			
		||||
@item Add a call to @file{vcvars32.bat} (which sets up the environment
 | 
			
		||||
variables for the Visual C++ tools) as the first line of @file{msys.bat}.
 | 
			
		||||
The standard location for @file{vcvars32.bat} is
 | 
			
		||||
@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
 | 
			
		||||
and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
 | 
			
		||||
If this corresponds to your setup, add the following line as the first line
 | 
			
		||||
of @file{msys.bat}:
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
 | 
			
		||||
and run @file{c:\msys\1.0\msys.bat} from there.
 | 
			
		||||
 | 
			
		||||
@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
 | 
			
		||||
from @file{Microsoft (R) Library Manager}, this means your environment
 | 
			
		||||
variables are set up correctly, the @file{Microsoft (R) Library Manager}
 | 
			
		||||
is on the path and will be used by FFmpeg to create
 | 
			
		||||
MSVC++-compatible import libraries.
 | 
			
		||||
 | 
			
		||||
@item Build FFmpeg with
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
./configure --enable-shared
 | 
			
		||||
make
 | 
			
		||||
make install
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
Your install path (@file{/usr/local/} by default) should now have the
 | 
			
		||||
necessary DLL and LIB files under the @file{bin} directory.
 | 
			
		||||
 | 
			
		||||
@end enumerate
 | 
			
		||||
 | 
			
		||||
Alternatively, build the libraries with a cross compiler, according to
 | 
			
		||||
the instructions below in @ref{Cross compilation for Windows with Linux}.
 | 
			
		||||
 | 
			
		||||
To use those files with MSVC++, do the same as you would do with
 | 
			
		||||
the static libraries, as described above. But in Step 4,
 | 
			
		||||
you should only need to add the directory where the LIB files are installed
 | 
			
		||||
(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
 | 
			
		||||
installed in the @file{bin} directory. And instead of adding the static
 | 
			
		||||
libraries (@file{libxxx.a} files) you should add the MSVC import libraries
 | 
			
		||||
(@file{avcodec.lib}, @file{avformat.lib}, and
 | 
			
		||||
@file{avutil.lib}). Note that you should not use the GCC import
 | 
			
		||||
libraries (@file{libxxx.dll.a} files), as these will give you undefined
 | 
			
		||||
reference errors. There should be no need for @file{libmingwex.a},
 | 
			
		||||
@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
 | 
			
		||||
statically linked into the DLLs.
 | 
			
		||||
 | 
			
		||||
FFmpeg headers do not declare global data for Windows DLLs through the usual
 | 
			
		||||
dllexport/dllimport interface. Such data will be exported properly while
 | 
			
		||||
building, but to use them in your MSVC++ code you will have to edit the
 | 
			
		||||
appropriate headers and mark the data as dllimport. For example, in
 | 
			
		||||
libavutil/pixdesc.h you should have:
 | 
			
		||||
@example
 | 
			
		||||
extern __declspec(dllimport) const AVPixFmtDescriptor av_pix_fmt_descriptors[];
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
Note that using import libraries created by dlltool requires
 | 
			
		||||
the linker optimization option to be set to
 | 
			
		||||
"References: Keep Unreferenced Data (@code{/OPT:NOREF})", otherwise
 | 
			
		||||
the resulting binaries will fail during runtime. This isn't
 | 
			
		||||
required when using import libraries generated by lib.exe.
 | 
			
		||||
This issue is reported upstream at
 | 
			
		||||
@url{http://sourceware.org/bugzilla/show_bug.cgi?id=12633}.
 | 
			
		||||
 | 
			
		||||
To create import libraries that work with the @code{/OPT:REF} option
 | 
			
		||||
(which is enabled by default in Release mode), follow these steps:
 | 
			
		||||
 | 
			
		||||
@enumerate
 | 
			
		||||
 | 
			
		||||
@item Open @file{Visual Studio 2005 Command Prompt}.
 | 
			
		||||
 | 
			
		||||
Alternatively, in a normal command line prompt, call @file{vcvars32.bat}
 | 
			
		||||
which sets up the environment variables for the Visual C++ tools
 | 
			
		||||
(the standard location for this file is
 | 
			
		||||
@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat}).
 | 
			
		||||
 | 
			
		||||
@item Enter the @file{bin} directory where the created LIB and DLL files
 | 
			
		||||
are stored.
 | 
			
		||||
 | 
			
		||||
@item Generate new import libraries with @file{lib.exe}:
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
lib /machine:i386 /def:..\lib\avcodec-53.def  /out:avcodec.lib
 | 
			
		||||
lib /machine:i386 /def:..\lib\avdevice-53.def /out:avdevice.lib
 | 
			
		||||
lib /machine:i386 /def:..\lib\avfilter-2.def  /out:avfilter.lib

You must use the MinGW cross compilation tools available at
 |

@url{http://www.mingw.org/}.
 | 
			
		||||
 | 
			
		||||
Then configure FFmpeg with the following options:

		||||
./configure --target-os=mingw32 --cross-prefix=i386-mingw32msvc-
 |

@end example
 |

(you can change the cross-prefix according to the prefix chosen for the
 | 
			
		||||
MinGW tools).
 |

to make a static build.
 |

 |

The current @code{gcc4-core} package is buggy and needs this flag to build
 |

shared libraries:
 |

@example

./configure --enable-shared --disable-static --extra-cflags=-fno-reorder-functions

If you want to build FFmpeg with additional libraries, download Cygwin
 | 
			
		||||
"Devel" packages for Ogg and Vorbis from any Cygwin packages repository:
 | 
			
		||||
@example
 | 
			
		||||
libogg-devel, libvorbis-devel
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
These library packages are only available from
 | 
			
		||||
@uref{http://sourceware.org/cygwinports/, Cygwin Ports}:
 | 
			
		||||
 | 
			
		||||
@example
 | 
			
		||||
yasm, libSDL-devel, libdirac-devel, libfaac-devel, libaacplus-devel, libgsm-devel,
 | 
			
		||||
libmp3lame-devel, libschroedinger1.0-devel, speex-devel, libtheora-devel,
 | 
			
		||||
libxvidcore-devel
 | 
			
		||||
@end example
 | 
			
		||||
 | 
			
		||||
The recommendation for libnut and x264 is to build them from source by
 | 
			
		||||
yourself, as they evolve too quickly for Cygwin Ports to be up to date.
 | 
			
		||||
 | 
			
		||||
Cygwin 1.7.x has IPv6 support. You can add IPv6 to Cygwin 1.5.x by means
 | 
			
		||||
of the @code{libgetaddrinfo-devel} package, available at Cygwin Ports.

@section Crosscompilation for Windows under Cygwin
 | 
			
		||||
 | 
			
		||||
With Cygwin you can create Windows binaries that do not need the cygwin1.dll.
 | 
			
		||||
 | 
			
		||||
Just install your Cygwin as explained before, plus these additional
 | 
			
		||||
"Devel" packages:
 | 
			
		||||
@example
 | 
			
		||||
gcc-mingw-core, mingw-runtime, mingw-zlib
 |

@end example
 | 
			
		||||
 | 
			
		||||
and add some special flags to your configure invocation.
 | 
			
		||||
 |

Every step can be skiped without memcpy when its not needed.
 | 
			
		||||
Either Resampling and Rematrixing can be performed first depending on which
 | 
			
		||||
way its faster.
 | 
			
		||||
The Buffers are needed for resampling due to resamplng being a process that
 | 
			
		||||
requires future and past data, it thus also introduces inevitably a delay when
 | 
			
		||||
used.
 | 
			
		||||
Internally 32bit float and 16bit int is supported currently, other formats can

easily be added

Externally all sample formats in packed and planar configuration are supported
 | 
			
		||||
Its also trivial to add special converters for common cases
 | 
			
		||||
If only sample format and or packed/planar convertion is needed it
 | 
			
		||||
is performed from input to output directly in a single pass with no intermediates.
