- ┌───────────────────────────────────────────┐
- │ RELEASE NOTES for FFmpeg 2.3 "Mandelbrot" │
- └───────────────────────────────────────────┘
-
-   The FFmpeg Project proudly presents FFmpeg 2.3 "Mandelbrot", a major
-   release with all the great features committed during the three-month period
-   since the release of FFmpeg 2.2.
-
-   In this release, there are lots of internal overhauls that make FFmpeg a
-   more accessible project for new developers. Many important new features
-   like QTKit and AVFoundation input devices are committed. Contributions done
-   by Libav such as a new native Opus decoder are also merged.
-
-   Because of the increasing difficulty to maintain and lack of maintainers,
-   we are very sorry to say that we have removed all Blackfin and SPARC
-   architecture assembly optimizations with the cleanups done. If you are
-   interested in maintaining optimization for these two architecture, feel
-   free to contact us and we will restore the code!
-
-   Since this release, the traditional Changelog file is upgraded to this
-   modern-looking release note. Old changelogs are moved to doc/Changelog.old.
-
-   Enjoy!
-
-   ┌────────────────────────────┐
-   │ *  API Information         │
-   └────────────────────────────┘
-
-     FFmpeg 2.3 is completely source-compatible to the FFmpeg 2.2 series. There
-     are however some API deprecations that you need to take care of. Use `git
-     diff n2.2 n2.3 doc/APIchanges` to show the list of added and deprecated
-     APIs. FFmpeg 2.3 includes the following library versions:
-
-       • libavutil      52.92.100
-       • libavcodec     55.69.100
-       • libavformat    55.47.100
-       • libavdevice    55.13.102
-       • libavfilter     4.10.100
-       • libswscale      2. 6.100
-       • libswresample   0.19.100
-       • libpostproc    52. 3.100
-
-     Please refer to the doc/APIChanges file for more information.
-
-   ┌────────────────────────────┐
-   │ New Optimization           │
-   └────────────────────────────┘
-
-     We are excited to announce that we have committed new x86 assembly
-     optimization for HEVC, and FFmpeg's audio resampler libswresample. ARM
-     users will get a boost in MLP/TrueHD decoding thanks to new optimization.
-     Decoding Huffyuv also got a major boost from optimization on the C code.
-
-     Of special interest for Microsoft Visual Studio users, we have also
-     converted some preexisting x86 assembly to NASM/Yasm format compatible
-     with MSVC setup, especially in the area of audio resampling.
-
-     Another major feature in this release is the introduction of AArch64
-     (ARMv8) assembly optimization. AArch64 is another name for the first
-     64-bit ARM architecture, used by Apple A7 SoC inside iPhone 5S. Some
-     32-bit ARM assembly has already been ported to AArch64, but more work is
-     underway.
-
-   ┌────────────────────────────┐
-   │ Native Opus decoder        │
-   └────────────────────────────┘
-
-     Opus is an open audio format jointly developed by Xiph.Org, Mozilla,
-     Skype/Microsoft, and Broadcom. It combines the features of the Skype Cilk
-     speech codec and the Xiph.Org CELT music codec into one low-latency
-     codec. Decoding Opus is already possible since FFmpeg 1.0 using the
-     libopus library, but the new Opus native decoder brings a higher level of
-     stability and speed.
-
-   ┌────────────────────────────┐
-   │ QTKit and AVFoundation     │
-   └────────────────────────────┘
-
-     For OS X users, the new QTKit and AVFoundation devices allow you to use
-     the integrated camera on Macs. AVFoundation is a newer API only available
-     on OS X 10.7 "Lion" or newer. For users with older OS X systems, the
-     QTKit device using the older OS X API is for you.
-
-   ┌────────────────────────────┐
-   │ API Additions              │
-   └────────────────────────────┘
-
-     In this release, stream side data are introduced as AVStream.side_data as
-     a way to store miscellaneous stream-wide information. The format is
-     similar to the previously anonymous structure AVPacket.side_data (now
-     named as AVPacketSideData). With this change, audio ReplayGain
-     information and video rotation matrix are now exported through this API,
-     if available in the demuxer.
-
-     We also have improved libswresample's Doxygen API documentation, so new
-     developers wishing to use FFmpeg's excellent libraries can get started
-     more easily and faster.
-
-   ┌────────────────────────────┐
-   │ Last But Not Least         │
-   └────────────────────────────┘
-
-     Other interesting new features including hqx video filter, a pixel art
-     scaling filter; a fixed-point AC-3 decoder contributed by Imagination
-     Technologies; an On2 TrueMotion VP7 video decoder; an HTML5 WebVTT
-     subtitle decoder that allows creation of WebVTT from any text-based
-     subtitles; and an 1-bit Direct Stream Digital audio decoder.

+AVUtil
+======
+libavutil is a small lightweight library of generally useful functions.
+It is not a library for code needed by both libavcodec and libavformat.
+
+
+Overview:
+=========
+adler32.c               adler32 checksum
+aes.c                   AES encryption and decryption
+fifo.c                  resizeable first in first out buffer
+intfloat_readwrite.c    portable reading and writing of floating point values
+log.c                   "printf" with context and level
+md5.c                   MD5 Message-Digest Algorithm
+rational.c              code to perform exact calculations with rational numbers
+tree.c                  generic AVL tree
+crc.c                   generic CRC checksumming code
+integer.c               128bit integer math
+lls.c
+mathematics.c           greatest common divisor, integer sqrt, integer log2, ...
+mem.c                   memory allocation routines with guaranteed alignment
+
+Headers:
+bswap.h                 big/little/native-endian conversion code
+x86_cpu.h               a few useful macros for unifying x86-64 and x86-32 code
+avutil.h
+common.h
+intreadwrite.h          reading and writing of unaligned big/little/native-endian integers
+
+
+Goals:
+======
+* Modular (few interdependencies and the possibility of disabling individual parts during ./configure)
+* Small (source and object)
+* Efficient (low CPU and memory usage)
+* Useful (avoid useless features almost no one needs)

-This document is mostly useful for internal FFmpeg developers.

+streams.

-You can use the FFmpeg libraries in your commercial program, but you

+
+You can integrate all the source code of the libraries to link them

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

-@chapter Detailed description
-
-@command{ffserver} works by forwarding streams encoded by
-@command{ffmpeg}, or pre-recorded streams which are read from disk.
-
-Precisely, @command{ffserver} acts as an HTTP server, accepting POST
-requests from @command{ffmpeg} to acquire the stream to publish, and
-serving RTSP clients or HTTP clients GET requests with the stream
-media content.
-
-A feed is an @ref{FFM} stream created by @command{ffmpeg}, and sent to
-a port where @command{ffserver} is listening.
-
-Each feed is identified by a unique name, corresponding to the name
-of the resource published on @command{ffserver}, and is configured by
-a dedicated @code{Feed} section in the configuration file.
-
-The feed publish URL is given by:
-@example
-http://@var{ffserver_ip_address}:@var{http_port}/@var{feed_name}
-@end example
-
-where @var{ffserver_ip_address} is the IP address of the machine where
-@command{ffserver} is installed, @var{http_port} is the port number of
-the HTTP server (configured through the @option{Port} option), and
-@var{feed_name} is the name of the corresponding feed defined in the
-configuration file.
-
-Each feed is associated to a file which is stored on disk. This stored
-file is used to allow to send pre-recorded data to a player as fast as
-possible when new content is added in real-time to the stream.
-
-A "live-stream" or "stream" is a resource published by
-@command{ffserver}, and made accessible through the HTTP protocol to
-clients.
-
-A stream can be connected to a feed, or to a file. In the first case,
-the published stream is forwarded from the corresponding feed
-generated by a running instance of @command{ffmpeg}, in the second
-case the stream is read from a pre-recorded file.
-
-Each stream is identified by a unique name, corresponding to the name
-of the resource served by @command{ffserver}, and is configured by
-a dedicated @code{Stream} section in the configuration file.
-
-The stream access HTTP URL is given by:
-@example
-http://@var{ffserver_ip_address}:@var{http_port}/@var{stream_name}[@var{options}]
-@end example
-
-The stream access RTSP URL is given by:
-@example
-http://@var{ffserver_ip_address}:@var{rtsp_port}/@var{stream_name}[@var{options}]
-@end example
-
-@var{stream_name} is the name of the corresponding stream defined in
-the configuration file. @var{options} is a list of options specified
-after the URL which affects how the stream is served by
-@command{ffserver}. @var{http_port} and @var{rtsp_port} are the HTTP
-and RTSP ports configured with the options @var{Port} and
-@var{RTSPPort} respectively.
-
-In case the stream is associated to a feed, the encoding parameters
-must be configured in the stream configuration. They are sent to
-@command{ffmpeg} when setting up the encoding. This allows
-@command{ffserver} to define the encoding parameters used by
-the @command{ffmpeg} encoders.
-
-The @command{ffmpeg} @option{override_ffserver} commandline option
-allows one to override the encoding parameters set by the server.
-
-Multiple streams can be connected to the same feed.

-For example, you can have a situation described by the following
-graph:

-@chapter Configuration file syntax
-
-@command{ffserver} reads a configuration file containing global
-options and settings for each stream and feed.
-
-The configuration file consists of global options and dedicated
-sections, which must be introduced by "<@var{SECTION_NAME}
-@var{ARGS}>" on a separate line and must be terminated by a line in
-the form "</@var{SECTION_NAME}>". @var{ARGS} is optional.
-
-Currently the following sections are recognized: @samp{Feed},
-@samp{Stream}, @samp{Redirect}.
-
-A line starting with @code{#} is ignored and treated as a comment.
-
-Name of options and sections are case-insensitive.
-
-@section ACL syntax
-An ACL (Access Control List) specifies the address which are allowed
-to access a given stream, or to write a given feed.
-
-It accepts the folling forms
-@itemize
-@item
-Allow/deny access to @var{address}.
-@example
-ACL ALLOW <address>
-ACL DENY <address>
-@end example
-
-@item
-Allow/deny access to ranges of addresses from @var{first_address} to
-@var{last_address}.
-@example
-ACL ALLOW <first_address> <last_address>
-ACL DENY <first_address> <last_address>
-@end example
-@end itemize
-
-You can repeat the ACL allow/deny as often as you like. It is on a per
-stream basis. The first match defines the action. If there are no matches,
-then the default is the inverse of the last ACL statement.
-
-Thus 'ACL allow localhost' only allows access from localhost.
-'ACL deny 1.0.0.0 1.255.255.255' would deny the whole of network 1 and
-allow everybody else.
-
-@section Global options
-@table @option
-@item Port @var{port_number}
-@item RTSPPort @var{port_number}
-
-Set TCP port number on which the HTTP/RTSP server is listening. You
-must select a different port from your standard HTTP web server if it
-is running on the same computer.
-
-If not specified, no corresponding server will be created.
-
-@item BindAddress @var{ip_address}
-@item RTSPBindAddress @var{ip_address}
-Set address on which the HTTP/RTSP server is bound. Only useful if you
-have several network interfaces.
-
-@item MaxHTTPConnections @var{n}
-Set number of simultaneous HTTP connections that can be handled. It
-has to be defined @emph{before} the @option{MaxClients} parameter,
-since it defines the @option{MaxClients} maximum limit.
-
-Default value is 2000.
-
-@item MaxClients @var{n}
-Set number of simultaneous requests that can be handled. Since
-@command{ffserver} is very fast, it is more likely that you will want
-to leave this high and use @option{MaxBandwidth}.
-
-Default value is 5.
-
-@item MaxBandwidth @var{kbps}
-Set the maximum amount of kbit/sec that you are prepared to consume
-when streaming to clients.
-
-Default value is 1000.
-
-@item CustomLog @var{filename}
-Set access log file (uses standard Apache log file format). '-' is the
-standard output.
-
-If not specified @command{ffserver} will produce no log.
-
-In case the commandline option @option{-d} is specified this option is
-ignored, and the log is written to standard output.
-
-@item NoDaemon
-Set no-daemon mode. This option is currently ignored since now
-@command{ffserver} will always work in no-daemon mode, and is
-deprecated.

-@section Feed section
-
-A Feed section defines a feed provided to @command{ffserver}.
-
-Each live feed contains one video and/or audio sequence coming from an
-@command{ffmpeg} encoder or another @command{ffserver}. This sequence
-may be encoded simultaneously with several codecs at several
-resolutions.
-
-A feed instance specification is introduced by a line in the form:
-@example
-<Feed FEED_FILENAME>
-@end example
-
-where @var{FEED_FILENAME} specifies the unique name of the FFM stream.
-
-The following options are recognized within a Feed section.
-
-@table @option
-@item File @var{filename}
-@item ReadOnlyFile @var{filename}
-Set the path where the feed file is stored on disk.
-
-If not specified, the @file{/tmp/FEED.ffm} is assumed, where
-@var{FEED} is the feed name.
-
-If @option{ReadOnlyFile} is used the file is marked as read-only and
-it will not be deleted or updated.
-
-@item Truncate
-Truncate the feed file, rather than appending to it. By default
-@command{ffserver} will append data to the file, until the maximum
-file size value is reached (see @option{FileMaxSize} option).
-
-@item FileMaxSize @var{size}
-Set maximum size of the feed file in bytes. 0 means unlimited. The
-postfixes @code{K} (2^10), @code{M} (2^20), and @code{G} (2^30) are
-recognized.
-
-Default value is 5M.
-
-@item Launch @var{args}
-Launch an @command{ffmpeg} command when creating @command{ffserver}.
-
-@var{args} must be a sequence of arguments to be provided to an
-@command{ffmpeg} instance. The first provided argument is ignored, and
-it is replaced by a path with the same dirname of the @command{ffserver}
-instance, followed by the remaining argument and terminated with a
-path corresponding to the feed.
-
-When the launched process exits, @command{ffserver} will launch
-another program instance.
-
-In case you need a more complex @command{ffmpeg} configuration,
-e.g. if you need to generate multiple FFM feeds with a single
-@command{ffmpeg} instance, you should launch @command{ffmpeg} by hand.
-
-This option is ignored in case the commandline option @option{-n} is
-specified.
-
-@item ACL @var{spec}
-Specify the list of IP address which are allowed or denied to write
-the feed. Multiple ACL options can be specified.
-@end table
-
-@section Stream section
-
-A Stream section defines a stream provided by @command{ffserver}, and
-identified by a single name.
-
-The stream is sent when answering a request containing the stream
-name.
-
-A stream section must be introduced by the line:
-@example
-<Stream STREAM_NAME>
-@end example
-
-where @var{STREAM_NAME} specifies the unique name of the stream.
-
-The following options are recognized within a Stream section.
-
-Encoding options are marked with the @emph{encoding} tag, and they are
-used to set the encoding parameters, and are mapped to libavcodec
-encoding options. Not all encoding options are supported, in
-particular it is not possible to set encoder private options. In order
-to override the encoding options specified by @command{ffserver}, you
-can use the @command{ffmpeg} @option{override_ffserver} commandline
-option.
-
-Only one of the @option{Feed} and @option{File} options should be set.
-
-@table @option
-@item Feed @var{feed_name}
-Set the input feed. @var{feed_name} must correspond to an existing
-feed defined in a @code{Feed} section.
-
-When this option is set, encoding options are used to setup the
-encoding operated by the remote @command{ffmpeg} process.
-
-@item File @var{filename}
-Set the filename of the pre-recorded input file to stream.
-
-When this option is set, encoding options are ignored and the input
-file content is re-streamed as is.
-
-@item Format @var{format_name}
-Set the format of the output stream.
-
-Must be the name of a format recognized by FFmpeg. If set to
-@samp{status}, it is treated as a status stream.
-
-@item InputFormat @var{format_name}
-Set input format. If not specified, it is automatically guessed.
-
-@item Preroll @var{n}
-Set this to the number of seconds backwards in time to start. Note that
-most players will buffer 5-10 seconds of video, and also you need to allow
-for a keyframe to appear in the data stream.
-
-Default value is 0.
-
-@item StartSendOnKey
-Do not send stream until it gets the first key frame. By default
-@command{ffserver} will send data immediately.
-
-@item MaxTime @var{n}
-Set the number of seconds to run. This value set the maximum duration
-of the stream a client will be able to receive.
-
-A value of 0 means that no limit is set on the stream duration.
-
-@item ACL @var{spec}
-Set ACL for the stream.

-@item AudioChannels @var{n} (@emph{encoding,audio})
-Set number of audio channels.
-
-@item AudioSampleRate @var{n} (@emph{encoding,audio})
-Set sampling frequency for audio. When using low bitrates, you should
-lower this frequency to 22050 or 11025. The supported frequencies

+About Git write access:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Before everything else, you should know how to use GIT properly.
+Luckily Git comes with excellent documentation.
+
+  git --help
+  man git
+
+shows you the available subcommands,
+
+  git <command> --help
+  man git-<command>
+
+shows information about the subcommand <command>.
+
+The most comprehensive manual is the website Git Reference
+
+http://gitref.org/
+
+For more information about the Git project, visit
+
+http://git-scm.com/
+
+Consult these resources whenever you have problems, they are quite exhaustive.
+
+You do not need a special username or password.
+All you need is to provide a ssh public key to the Git server admin.
+
+What follows now is a basic introduction to Git and some FFmpeg-specific
+guidelines. Read it at least once, if you are granted commit privileges to the
+FFmpeg project you are expected to be familiar with these rules.
+
+
+
+I. BASICS:
+==========
+
+0. Get GIT:
+
+  Most distributions have a git package, if not
+  You can get git from http://git-scm.com/
+
+
+1. Cloning the source tree:
+
+    git clone git://source.ffmpeg.org/ffmpeg <target>
+
+  This will put the FFmpeg sources into the directory <target>.
+
+    git clone git@source.ffmpeg.org:ffmpeg <target>
+
+  This will put the FFmpeg sources into the directory <target> and let
+  you push back your changes to the remote repository.
+
+
+2. Updating the source tree to the latest revision:
+
+    git pull (--ff-only)
+
+  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.
+  Caveat: Since merge commits are forbidden at least for the initial
+          months of git --ff-only or --rebase (see below) are recommended.
+          --ff-only will fail and not create merge commits if your branch
+          has diverged (has a different history) from the tracked branch.
+
+2.a Rebasing your local branches:
+
+    git pull --rebase
+
+  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.
+
+
+3. Adding/removing files/directories:
+
+    git add [-A] <filename/dirname>
+    git rm [-r] <filename/dirname>
+
+  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.
+
+
+4. Showing modifications:
+
+    git diff <filename(s)>
+
+  will show all local modifications in your working directory as unified diff.
+
+
+5. Inspecting the changelog:
+
+    git log <filename(s)>
+
+  You may also use the graphical tools like gitview or gitk or the web
+  interface available at http://source.ffmpeg.org
+
+6. Checking source tree status:
+
+    git status
+
+  detects all the changes you made and lists what actions will be taken in case
+  of a commit (additions, modifications, deletions, etc.).
+
+
+7. Committing:
+
+    git diff --check
+
+  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
+
+    git diff -w -b <filename(s)>
+
+  Also check the output of
+
+    git status
+
+  to make sure you don't have untracked files or deletions.
+
+    git add [-i|-p|-A] <filenames/dirnames>
+
+  Make sure you have told git your name and email address, e.g. by running
+    git config --global user.name "My Name"
+    git config --global user.email my@email.invalid
+  (--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.
+
+    git commit
+
+  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
+
+    git config core.editor
+
+  or set by one of the following environment variables:
+  GIT_EDITOR, VISUAL or 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.
+
+
+8. Renaming/moving/copying files or contents of files:
+
+  Git automatically tracks such changes, making those normal commits.
+
+    mv/cp path/file otherpath/otherfile
+
+    git add [-A] .
+
+    git commit
+
+  Do not move, rename or copy files of which you are not the maintainer without
+  discussing it on the mailing list first!
+
+9. Reverting broken commits
+
+    git revert <commit>
+
+  git revert will generate a revert commit. This will not make the faulty
+  commit disappear from the history.
+
+    git reset <commit>
+
+  git reset will uncommit the changes till <commit> rewriting the current
+  branch history.
+
+    git commit --amend
+
+  allows to amend the last commit details quickly.
+
+    git rebase -i origin/master
+
+  will replay local commits over the main repository allowing to edit,
+  merge or remove some of them in the process.
+
+  Note that the reset, commit --amend and rebase rewrite history, so you
+  should use them ONLY on your local or topic branches.
+
+  The main repository will reject those changes.
+
+10. Preparing a patchset.
+
+    git format-patch <commit> [-o directory]
+
+  will generate a set of patches for each commit between <commit> and
+  current HEAD. E.g.
+
+    git format-patch origin/master
+
+  will generate patches for all commits on current branch which are not
+  present in upstream.
+  A useful shortcut is also
+
+    git format-patch -n
+
+  which will generate patches from last n commits.
+  By default the patches are created in the current directory.
+
+11. Sending patches for review
+
+    git send-email <commit list|directory>
+
+  will send the patches created by 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. git-email
+  package on Debian-based distros).
+
+12. Pushing changes to remote trees
+
+    git push
+
+  Will push the changes to the default remote (origin).
+  Git will prevent you from pushing changes if the local and remote trees are
+  out of sync. Refer to 2 and 2.a to sync the local tree.
+
+    git remote add <name> <url>
+
+  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.
+
+    git push <remote> <refspec>
+
+  Will push the changes to the remote repository. Omitting refspec makes git
+  push update all the remote branches matching the local ones.
+
+13. Finding a specific svn revision
+
+  Since version 1.7.1 git supports ':/foo' syntax for specifying commits
+  based on a regular expression. see man gitrevisions
+
+    git show :/'as revision 23456'
+
+  will show the svn changeset r23456. With older git versions searching in
+  the git log output is the easiest option (especially if a pager with
+  search capabilities is used).
+  This commit can be checked out with
+
+    git checkout -b svn_23456 :/'as revision 23456'
+
+  or for git < 1.7.1 with
+
+    git checkout -b svn_23456 $SHA1
+
+  where $SHA1 is the commit SHA1 from the 'git log' output.
+
+
+Contact the project admins <root at ffmpeg dot org> if you have technical
+problems with the GIT server.

-Win32 GDI-based screen capture device.
-
-This device allows you to capture a region of the display on Windows.
-
-There are two options for the input filename:
-@example
-desktop
-@end example
-or
-@example
-title=@var{window_title}
-@end example
-
-The first option will capture the entire desktop, or a fixed region of the
-desktop. The second option will instead capture the contents of a single
-window, regardless of its position on the screen.
-
-For example, to grab the entire desktop using @command{ffmpeg}:
-@example
-ffmpeg -f gdigrab -framerate 6 -i desktop out.mpg
-@end example
-
-Grab a 640x480 region at position @code{10,20}:
-@example
-ffmpeg -f gdigrab -framerate 6 -offset_x 10 -offset_y 20 -video_size vga -i desktop out.mpg
-@end example
-
-Grab the contents of the window named "Calculator"
-@example
-ffmpeg -f gdigrab -framerate 6 -i title=Calculator out.mpg
-@end example
-
-@subsection Options
-
-@table @option
-@item draw_mouse
-Specify whether to draw the mouse pointer. Use the value @code{0} to
-not draw the pointer. Default value is @code{1}.
-
-@item framerate
-Set the grabbing frame rate. Default value is @code{ntsc},
-corresponding to a frame rate of @code{30000/1001}.
-
-@item show_region
-Show grabbed region on screen.
-
-If @var{show_region} is specified with @code{1}, then the grabbing
-region will be indicated on screen. With this option, it is easy to
-know what is being grabbed if only a portion of the screen is grabbed.
-
-Note that @var{show_region} is incompatible with grabbing the contents
-of a single window.
-
-For example:
-@example
-ffmpeg -f gdigrab -show_region 1 -framerate 6 -video_size cif -offset_x 10 -offset_y 20 -i desktop out.mpg
-@end example
-
-@item video_size
-Set the video frame size. The default is to capture the full screen if @file{desktop} is selected, or the full window size if @file{title=@var{window_title}} is selected.
-
-@item offset_x
-When capturing a region with @var{video_size}, set the distance from the left edge of the screen or desktop.
-
-Note that the offset calculation is from the top left corner of the primary monitor on Windows. If you have a monitor positioned to the left of your primary monitor, you will need to use a negative @var{offset_x} value to move the region to that monitor.
-
-@item offset_y
-When capturing a region with @var{video_size}, set the distance from the top edge of the screen or desktop.
-
-Note that the offset calculation is from the top left corner of the primary monitor on Windows. If you have a monitor positioned above your primary monitor, you will need to use a negative @var{offset_y} value to move the region to that monitor.

+Google Summer of Code and similar project guidelines
+
+Summer of Code is a project by Google in which students are paid to implement
+some nice new features for various participating open source projects ...
+
+This text is a collection of things to take care of for the next soc as
+it's a little late for this year's soc (2006).
+
+The Goal:
+Our goal in respect to soc is and must be of course exactly one thing and
+that is to improve FFmpeg, to reach this goal, code must
+* conform to the development policy and patch submission guidelines
+* must improve FFmpeg somehow (faster, smaller, "better",
+  more codecs supported, fewer bugs, cleaner, ...)
+
+for mentors and other developers to help students to reach that goal it is
+essential that changes to their codebase are publicly visible, clean and
+easy reviewable that again leads us to:
+* use of a revision control system like git
+* separation of cosmetic from non-cosmetic changes (this is almost entirely
+  ignored by mentors and students in soc 2006 which might lead to a surprise
+  when the code will be reviewed at the end before a possible inclusion in
+  FFmpeg, individual changes were generally not reviewable due to cosmetics).
+* frequent commits, so that comments can be provided early

-A custom channel layout can be specified as a sequence of terms, separated by
-'+' or '|'. Each term can be:
-@itemize
-@item
-the name of a standard channel layout (e.g. @samp{mono},
-@samp{stereo}, @samp{4.0}, @samp{quad}, @samp{5.0}, etc.)
-
-@item
-the name of a single channel (e.g. @samp{FL}, @samp{FR}, @samp{FC}, @samp{LFE}, etc.)
-
-@item
-a number of channels, in decimal, optionally followed by 'c', yielding
-the default channel layout for that number of channels (see the
-function @code{av_get_default_channel_layout})
-
-@item
-a channel layout mask, in hexadecimal starting with "0x" (see the
-@code{AV_CH_*} macros in @file{libavutil/channel_layout.h}.
-@end itemize
-
-Starting from libavutil version 53 the trailing character "c" to
-specify a number of channels will be required, while a channel layout
-mask could also be specified as a decimal number (if and only if not
-followed by "c").
-
-See also the function @code{av_get_channel_layout} defined in
-@file{libavutil/channel_layout.h}.
