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

+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)

-Unpack DivX-style packed B-frames.
-
-DivX-style packed B-frames are not valid MPEG-4 and were only a
-workaround for the broken Video for Windows subsystem.
-They use more space, can cause minor AV sync issues, require more
-CPU power to decode (unless the player has some decoded picture queue
-to compensate the 2,0,2,0 frame per packet style) and cause
-trouble if copied into a standard container like mp4 or mpeg-ps/ts,
-because MPEG-4 decoders may not be able to decode them, since they are
-not valid MPEG-4.
-
-For example to fix an AVI file containing an MPEG-4 stream with
-DivX-style packed B-frames using @command{ffmpeg}, you can use the command:
-
-@example
-ffmpeg -i INPUT.avi -codec copy -bsf:v mpeg4_unpack_bframes OUTPUT.avi
-@end example
-
 @section noise
 
-Damages the contents of packets without damaging the container. Can be
-used for fuzzing or testing error resilience/concealment.
-
-Parameters:
-A numeral string, whose value is related to how often output bytes will
-be modified. Therefore, values below or equal to 0 are forbidden, and
-the lower the more frequent bytes will be modified, with 1 meaning
-every byte is modified.
-
-@example
-ffmpeg -i INPUT -c copy -bsf noise[=1] output.mkv
-@end example
-applies the modification to every byte.

-/**
- * @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.

-
-Somewhere along with your libraries, there is a @file{.pc} file (or several)

-
-If you need to @emph{add} directories to @command{pkg-config}'s search list

-@section How do I use @command{pkg-config} when cross-compiling?
-
-The best way is to install @command{pkg-config} in your cross-compilation
-environment. It will automatically use the cross-compilation libraries.
-
-You can also use @command{pkg-config} from the host environment by
-specifying explicitly @code{--pkg-config=pkg-config} to @command{configure}.
-In that case, you must point @command{pkg-config} to the correct directories
-using the @code{PKG_CONFIG_LIBDIR}, as explained in the previous entry.
-
-As an intermediate solution, you can place in your cross-compilation
-environment a script that calls the host @command{pkg-config} with
-@code{PKG_CONFIG_LIBDIR} set. That script can look like that:

-A lot of video codecs and formats can store the @emph{aspect ratio} of the

-@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{HTTPPort} 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 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{HTTPPort} 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:

+
+When properly configured and running, you can capture video and audio in real

-@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.

-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

-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

-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.

+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

-Specify whether to draw the mouse pointer. Use the value @code{0} to

-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

-
-Note that @var{show_region} is incompatible with grabbing the contents
-of a single window.

-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.
