-version 0.9:
+version 0.7:
-
-- openal input device added
-- boxblur filter added
-- BWF muxer
-- Flash Screen Video 2 decoder
-- 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.

 Release Notes
 =============
 
-* 0.10 "Freedom"  January, 2012
+* 0.8 "Love"  June, 2011
+* 0.7.1 "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
+This release enables frame-based multithreaded decoding for a number of codecs,
-are many more new features and bugfixes than whats listed there.
+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.

+- ffmpeg is now interactive and various information can be turned on/off while its running
-are, in order of preference:
+- resolution changing support in ffmpeg
-1) Try finding a way of accomplishing the same with public API.
+- sdl output device
-2) If there is no corresponding public API, but you think there should be,
+- optimizations in libavfilter that make it much faster
-post a request on the developer mailing list or IRC channel.
+- split, buffer, select, lut, negate filters amongth others
-3) Finally if your program needs access to FFmpeg / libavcodec / libavformat
+- more than 50 new video filters from mplayers libmpcodecs
-internals for some special reason then the best solution is to link statically.
+- many ARM NEON optimizations
-
+- nonfree libfaad support for AAC decoding removed
-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

-
-@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.
-@item p:@var{program_id}[:@var{stream_index}]
-If @var{stream_index} is given, then matches stream number @var{stream_index} in
-program with id @var{program_id}. Otherwise matches all streams in this program.

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

 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

 @chapter General Questions
 
+@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
+still experience the problem, then you can report it according to the
+guidelines in @url{http://ffmpeg.org/bugreports.html}.

 Moreover FFmpeg strives to support all codecs natively.

+Likely reasons
+@itemize
+@item We are busy and haven't had time yet to read your report or
+investigate the issue.

+@item You didn't use git HEAD.
+@item You reported a segmentation fault without gdb output.
+@item You describe a problem but not how to reproduce it.
+@item It's unclear if you use ffmpeg as command line tool or use
+libav* from another application.
+@item You speak about a video having problems on playback but
+not what you use to play it.
+@item We have no faint clue what you are talking about besides
+that it is related to FFmpeg.

-@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.

-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

+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
+the FFmpeg Windows Help Forum at
+@url{http://ffmpeg.arrozcru.org/}.
+
+@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.
+
+@end itemize
+
+@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 add [-A] <filename/dirname>
-git rm [-r] <filename/dirname>
-@end 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

-@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.

-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:

-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 w32api 3.13

-
-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

-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 @uref{http://www.winehq.com/, Wine}.
-
-@section 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
-@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.
-
-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

-Planar/Packed convertion is done when needed during sample format convertion
-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.
