-Release Notes
-=============
-
-* 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 enables frame-based multithreaded decoding for a number of codecs,
-including theora, huffyuv, VP8, H.263, mpeg4 and H.264. Additionally, there has
-been a major cleanup of
-both internal and external APIs. For this reason, the major versions of all
-libraries except libpostproc have been bumped. This means that 0.8 can be installed
-side-by-side with previous releases, on the other hand applications need to be
-recompiled to use 0.8.
-
-Other important changes are more than 200 bugfixes, known regressions were fixed
-w.r.t 0.5 and 0.6, additions of decoders including, but not limited to,
-AMR-WB, single stream LATM/LOAS, G.722 ADPCM, a native VP8 decoder
-and HE-AACv2. Additionally, many new de/muxers such as WebM in Matroska, Apple
-HTTP Live Streaming, SAP, IEC 61937 (S/PDIF) have been added.
-
-See the Changelog file for a list of significant changes.
-
-Bugreports against FFmpeg git master or the most recent FFmpeg release are
-accepted. If you are experiencing issues with any formally released version of
-FFmpeg, please try git master to check if the issue still exists. If it does,
-make your report against the development code following the usual bug reporting
-guidelines.
-
-Note, if you have difficulty building for mingw, try --disable-outdev=sdl
-
-
-API changes
------------
-
-Please see git log of the public headers or the file doc/APIchanges for
-programmer-centric information. Note that some long-time deprecated APIs have
-been removed. Also, a number of additional APIs have been deprecated and might
-be removed in the next release.
-
-
-Other notable changes
----------------------
-
-- high quality dithering in swscale to fix banding issues
-- ffmpeg is now interactive and various information can be turned on/off while its running
-- resolution changing support in ffmpeg
-- sdl output device
-- optimizations in libavfilter that make it much faster

-Convert MJPEG/AVI1 packets to full JPEG/JFIF packets.
-
-MJPEG is a video codec wherein each video frame is essentially a
-JPEG image. The individual frames can be extracted without loss,
-e.g. by
-
-@example
-ffmpeg -i ../some_mjpeg.avi -vcodec copy frames_%d.jpg
-@end example
-
-Unfortunately, these chunks are incomplete JPEG images, because
-they lack the DHT segment required for decoding. Quoting from
-@url{http://www.digitalpreservation.gov/formats/fdd/fdd000063.shtml}:
-
-Avery Lee, writing in the rec.video.desktop newsgroup in 2001,
-commented that "MJPEG, or at least the MJPEG in AVIs having the
-MJPG fourcc, is restricted JPEG with a fixed -- and *omitted* --
-Huffman table. The JPEG must be YCbCr colorspace, it must be 4:2:2,
-and it must use basic Huffman encoding, not arithmetic or
-progressive. . . . You can indeed extract the MJPEG frames and
-decode them with a regular JPEG decoder, but you have to prepend
-the DHT segment to them, or else the decoder won't have any idea
-how to decompress the data. The exact table necessary is given in
-the OpenDML spec."
-
-This bitstream filter patches the header of frames extracted from an MJPEG
-stream (carrying the AVI1 header ID and lacking a DHT segment) to
-produce fully qualified JPEG images.
-
-@example
-ffmpeg -i mjpeg-movie.avi -vcodec copy -vbsf mjpeg2jpeg frame_%d.jpg
-exiftran -i -9 frame*.jpg

-@chapter Demuxers
-@c man begin DEMUXERS
-
-Demuxers are configured elements in FFmpeg which allow to read the
-multimedia streams from a particular type of file.
-
-When you configure your FFmpeg build, all the supported demuxers
-are enabled by default. You can list all available ones using the
-configure option "--list-demuxers".
-
-You can disable all the demuxers using the configure option
-"--disable-demuxers", and selectively enable a single demuxer with
-the option "--enable-demuxer=@var{DEMUXER}", or disable it
-with the option "--disable-demuxer=@var{DEMUXER}".
-
-The option "-formats" of the ff* tools will display the list of
-enabled demuxers.
-
-The description of some of the currently available demuxers follows.
-
-@section image2
-
-Image file demuxer.
-
-This demuxer reads from a list of image files specified by a pattern.
-
-The pattern may contain the string "%d" or "%0@var{N}d", which
-specifies the position of the characters representing a sequential
-number in each filename matched by the pattern. If the form
-"%d0@var{N}d" is used, the string representing the number in each
-filename is 0-padded and @var{N} is the total number of 0-padded
-digits representing the number. The literal character '%' can be
-specified in the pattern with the string "%%".
-
-If the pattern contains "%d" or "%0@var{N}d", the first filename of
-the file list specified by the pattern must contain a number
-inclusively contained between 0 and 4, all the following numbers must
-be sequential. This limitation may be hopefully fixed.
-
-The pattern may contain a suffix which is used to automatically
-determine the format of the images contained in the files.
-
-For example the pattern "img-%03d.bmp" will match a sequence of
-filenames of the form @file{img-001.bmp}, @file{img-002.bmp}, ...,
-@file{img-010.bmp}, etc.; the pattern "i%%m%%g-%d.jpg" will match a
-sequence of filenames of the form @file{i%m%g-1.jpg},
-@file{i%m%g-2.jpg}, ..., @file{i%m%g-10.jpg}, etc.
-
-The size, the pixel format, and the format of each image must be the
-same for all the files in the sequence.
-
-The following example shows how to use @file{ffmpeg} for creating a
-video from the images in the file sequence @file{img-001.jpeg},
-@file{img-002.jpeg}, ..., assuming an input framerate of 10 frames per
-second:
-@example
-ffmpeg -r 10 -f image2 -i 'img-%03d.jpeg' out.avi
-@end example
-
-Note that the pattern must not necessarily contain "%d" or
-"%0@var{N}d", for example to convert a single image file
-@file{img.jpeg} you can employ the command:
-@example
-ffmpeg -f image2 -i img.jpeg img.png
-@end example
-
-@section applehttp
-
-Apple HTTP Live Streaming demuxer.
-
-This demuxer presents all AVStreams from all variant streams.
-The id field is set to the bitrate variant index number. By setting
-the discard flags on AVStreams (by pressing 'a' or 'v' in ffplay),
-the caller can decide which variant streams to actually receive.
-The total bitrate of the variant that the stream belongs to is
-available in a metadata key named "variant_bitrate".

-AC-3 audio encoders.
-
-These encoders implement part of ATSC A/52:2010 and ETSI TS 102 366, as well as
-the undocumented RealAudio 3 (a.k.a. dnet).
-
-The @var{ac3} encoder uses floating-point math, while the @var{ac3_fixed}
-encoder only uses fixed-point integer math. This does not mean that one is
-always faster, just that one or the other may be better suited to a
-particular system. The floating-point encoder will generally produce better
-quality audio for a given bitrate. The @var{ac3_fixed} encoder is not the
-default codec for any of the output formats, so it must be specified explicitly
-using the option @code{-acodec ac3_fixed} in order to use it.
-
-@subsection AC-3 Metadata
-
-The AC-3 metadata options are used to set parameters that describe the audio,
-but in most cases do not affect the audio encoding itself. Some of the options
-do directly affect or influence the decoding and playback of the resulting
-bitstream, while others are just for informational purposes. A few of the
-options will add bits to the output stream that could otherwise be used for
-audio data, and will thus affect the quality of the output. Those will be
-indicated accordingly with a note in the option list below.
-
-These parameters are described in detail in several publicly-available
-documents.

-@chapter Expression Evaluation
-@c man begin EXPRESSION EVALUATION
-
-When evaluating an arithemetic expression, FFmpeg uses an internal
-formula evaluator, implemented through the @file{libavutil/eval.h}
-interface.
-
-An expression may contain unary, binary operators, constants, and
-functions.
-
-Two expressions @var{expr1} and @var{expr2} can be combined to form
-another expression "@var{expr1};@var{expr2}".
-@var{expr1} and @var{expr2} are evaluated in turn, and the new
-expression evaluates to the value of @var{expr2}.
-
-The following binary operators are available: @code{+}, @code{-},
-@code{*}, @code{/}, @code{^}.
-
-The following unary operators are available: @code{+}, @code{-}.
-
-The following functions are available:
-@table @option
-@item sinh(x)
-@item cosh(x)
-@item tanh(x)
-@item sin(x)
-@item cos(x)
-@item tan(x)
-@item atan(x)
-@item asin(x)
-@item acos(x)
-@item exp(x)
-@item log(x)
-@item abs(x)
-@item squish(x)
-@item gauss(x)
-@item isnan(x)
-Return 1.0 if @var{x} is NAN, 0.0 otherwise.
-
-@item mod(x, y)
-@item max(x, y)
-@item min(x, y)
-@item eq(x, y)
-@item gte(x, y)
-@item gt(x, y)
-@item lte(x, y)
-@item lt(x, y)
-@item st(var, expr)
-Allow to store the value of the expression @var{expr} in an internal
-variable. @var{var} specifies the number of the variable where to
-store the value, and it is a value ranging from 0 to 9. The function
-returns the value stored in the internal variable.
-
-@item ld(var)
-Allow to load the value of the internal variable with number
-@var{var}, which was previosly stored with st(@var{var}, @var{expr}).
-The function returns the loaded value.
-
-@item while(cond, expr)
-Evaluate expression @var{expr} while the expression @var{cond} is
-non-zero, and returns the value of the last @var{expr} evaluation, or
-NAN if @var{cond} was always false.
-
-@item ceil(expr)
-Round the value of expression @var{expr} upwards to the nearest
-integer. For example, "ceil(1.5)" is "2.0".
-
-@item floor(expr)
-Round the value of expression @var{expr} downwards to the nearest
-integer. For example, "floor(-1.5)" is "-2.0".
-
-@item trunc(expr)
-Round the value of expression @var{expr} towards zero to the nearest
-integer. For example, "trunc(-1.5)" is "-1.0".
-
-@item sqrt(expr)
-Compute the square root of @var{expr}. This is equivalent to
-"(@var{expr})^.5".
-
-@item not(expr)
-Return 1.0 if @var{expr} is zero, 0.0 otherwise.
-
-@item pow(x, y)
-Compute the power of @var{x} elevated @var{y}, it is equivalent to
-"(@var{x})^(@var{y})".
-@end table
-
-Note that:
-
-@code{*} works like AND
-
-@code{+} works like OR
-
-thus
-@example
-if A then B else C
-@end example
-is equivalent to
-@example
-A*B + not(A)*C
-@end example
-
-In your C code, you can extend the list of unary and binary functions,
-and define recognized constants, so that they are available for your
-expressions.
-
-The evaluator also recognizes the International System number
-postfixes. 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.
-
-Follows the list of available International System postfixes, with
-indication of the corresponding powers of 10 and of 2.

+FFmpeg & evaluating performance on the PowerPC Architecture HOWTO
+
+(c) 2003-2004 Romain Dolbeau <romain@dolbeau.org>
+
+
+
+I - Introduction
+
+The PowerPC architecture and its SIMD extension AltiVec offer some
+interesting tools to evaluate performance and improve the code.
+This document tries to explain how to use those tools with FFmpeg.
+
+The architecture itself offers two ways to evaluate the performance of
+a given piece of code:
+
+1) The Time Base Registers (TBL)
+2) The Performance Monitor Counter Registers (PMC)
+
+The first ones are always available, always active, but they're not very
+accurate: the registers increment by one every four *bus* cycles. On
+my 667 Mhz tiBook (ppc7450), this means once every twenty *processor*
+cycles. So we won't use that.
+
+The PMC are much more useful: not only can they report cycle-accurate
+timing, but they can also be used to monitor many other parameters,
+such as the number of AltiVec stalls for every kind of instruction,
+or instruction cache misses. The downside is that not all processors
+support the PMC (all G3, all G4 and the 970 do support them), and
+they're inactive by default - you need to activate them with a
+dedicated tool. Also, the number of available PMC depends on the
+procesor: the various 604 have 2, the various 75x (aka. G3) have 4,
+and the various 74xx (aka G4) have 6.
+
+*WARNING*: The PowerPC 970 is not very well documented, and its PMC
+registers are 64 bits wide. To properly notify the code, you *must*
+tune for the 970 (using --tune=970), or the code will assume 32 bit
+registers.
+
+
+II - Enabling FFmpeg PowerPC performance support
+
+This needs to be done by hand. First, you need to configure FFmpeg as
+usual, but add the "--powerpc-perf-enable" option. For instance:
+
+#####
+./configure --prefix=/usr/local/ffmpeg-svn --cc=gcc-3.3 --tune=7450 --powerpc-perf-enable
+#####
+
+This will configure FFmpeg to install inside /usr/local/ffmpeg-svn,
+compiling with gcc-3.3 (you should try to use this one or a newer
+gcc), and tuning for the PowerPC 7450 (i.e. the newer G4; as a rule of
+thumb, those at 550Mhz and more). It will also enable the PMC.
+
+You may also edit the file "config.h" to enable the following line:
+
+#####
+// #define ALTIVEC_USE_REFERENCE_C_CODE 1
+#####
+
+If you enable this line, then the code will not make use of AltiVec,
+but will use the reference C code instead. This is useful to compare
+performance between two versions of the code.
+
+Also, the number of enabled PMC is defined in "libavcodec/ppc/dsputil_ppc.h":
+
+#####
+#define POWERPC_NUM_PMC_ENABLED 4
+#####
+
+If you have a G4 CPU, you can enable all 6 PMC. DO NOT enable more
+PMC than available on your CPU!
+
+Then, simply compile FFmpeg as usual (make && make install).
+
+
+
+III - Using FFmpeg PowerPC performance support
+
+This FFmeg can be used exactly as usual. But before exiting, FFmpeg
+will dump a per-function report that looks like this:
+
+#####
+PowerPC performance report
+ Values are from the PMC registers, and represent whatever the
+ registers are set to record.
+ Function "gmc1_altivec" (pmc1):
+        min: 231
+        max: 1339867
+        avg: 558.25 (255302)
+ Function "gmc1_altivec" (pmc2):
+        min: 93
+        max: 2164
+        avg: 267.31 (255302)
+ Function "gmc1_altivec" (pmc3):
+        min: 72
+        max: 1987
+        avg: 276.20 (255302)
+(...)
+#####
+
+In this example, PMC1 was set to record CPU cycles, PMC2 was set to
+record AltiVec Permute Stall Cycles, and PMC3 was set to record AltiVec
+Issue Stalls.
+
+The function "gmc1_altivec" was monitored 255302 times, and the
+minimum execution time was 231 processor cycles. The max and average
+aren't much use, as it's very likely the OS interrupted execution for
+reasons of its own :-(
+
+With the exact same settings and source file, but using the reference C
+code we get:
+
+#####
+PowerPC performance report
+ Values are from the PMC registers, and represent whatever the
+ registers are set to record.
+ Function "gmc1_altivec" (pmc1):
+        min: 592
+        max: 2532235
+        avg: 962.88 (255302)
+ Function "gmc1_altivec" (pmc2):
+        min: 0
+        max: 33
+        avg: 0.00 (255302)
+ Function "gmc1_altivec" (pmc3):
+        min: 0
+        max: 350
+        avg: 0.03 (255302)
+(...)
+#####
+
+592 cycles, so the fastest AltiVec execution is about 2.5x faster than
+the fastest C execution in this example. It's not perfect but it's not
+bad (well I wrote this function so I can't say otherwise :-).
+
+Once you have that kind of report, you can try to improve things by
+finding what goes wrong and fixing it; in the example above, one
+should try to diminish the number of AltiVec stalls, as this *may*
+improve performance.
+
+
+
+IV) Enabling the PMC in Mac OS X
+
+This is easy. Use "Monster" and "monster". Those tools come from
+Apple's CHUD package, and can be found hidden in the developer web
+site & FTP site. "MONster" is the graphical application, use it to
+generate a config file specifying what each register should
+monitor. Then use the command-line application "monster" to use that
+config file, and enjoy the results.
+
+Note that "MONster" can be used for many other things, but it's
+documented by Apple, it's not my subject.
+
+If you are using CHUD 4.4.2 or later, you'll notice that MONster is
+no longer available. It's been superseeded by Shark, where
+configuration of PMCs is available as a plugin.
+
+
+
+V) Enabling the PMC on Linux
+
+On linux you may use oprofile from http://oprofile.sf.net, depending on the
+version and the cpu you may need to apply a patch[1] to access a set of the
+possibile counters from the userspace application. You can always define them
+using the kernel interface /dev/oprofile/* .

-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:
-
-  You can get git from http://git-scm.com/
-
-
-1. Cloning the source tree:
-
-    git clone git://git.videolan.org/ffmpeg <target>
-
-  This will put the FFmpeg sources into the directory <target>.
-
-    git clone git@git.videolan.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://git.videolan.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 out of the current branch starting from
-  commit. 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.
-
-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.

-@chapter Input Devices
-@c man begin INPUT DEVICES
-
-Input devices are configured elements in FFmpeg which allow to access
-the data coming from a multimedia device attached to your system.
-
-When you configure your FFmpeg build, all the supported input devices
-are enabled by default. You can list all available ones using the
-configure option "--list-indevs".
-
-You can disable all the input devices using the configure option
-"--disable-indevs", and selectively enable an input device using the
-option "--enable-indev=@var{INDEV}", or you can disable a particular
-input device using the option "--disable-indev=@var{INDEV}".
-
-The option "-formats" of the ff* tools will display the list of
-supported input devices (amongst the demuxers).
-
-A description of the currently available input devices follows.
-
-@section alsa
-
-ALSA (Advanced Linux Sound Architecture) input device.
-
-To enable this input device during configuration you need libasound
-installed on your system.
-
-This device allows capturing from an ALSA device. The name of the
-device to capture has to be an ALSA card identifier.
-
-An ALSA identifier has the syntax:
-@example
-hw:@var{CARD}[,@var{DEV}[,@var{SUBDEV}]]
-@end example
-
-where the @var{DEV} and @var{SUBDEV} components are optional.
-
-The three arguments (in order: @var{CARD},@var{DEV},@var{SUBDEV})
-specify card number or identifier, device number and subdevice number
-(-1 means any).
-
-To see the list of cards currently recognized by your system check the
-files @file{/proc/asound/cards} and @file{/proc/asound/devices}.
-
-For example to capture with @file{ffmpeg} from an ALSA device with
-card id 0, you may run the command:
-@example
-ffmpeg -f alsa -i hw:0 alsaout.wav
-@end example
-
-For more information see:
-@url{http://www.alsa-project.org/alsa-doc/alsa-lib/pcm.html}
-
-@section bktr
-
-BSD video input device.
-
-@section dv1394
-
-Linux DV 1394 input device.
-
-@section fbdev
-
-Linux framebuffer input device.
-
-The Linux framebuffer is a graphic hardware-independent abstraction
-layer to show graphics on a computer monitor, typically on the
-console. It is accessed through a file device node, usually
-@file{/dev/fb0}.
-
-For more detailed information read the file
-Documentation/fb/framebuffer.txt included in the Linux source tree.
-
-To record from the framebuffer device @file{/dev/fb0} with
-@file{ffmpeg}:
-@example
-ffmpeg -f fbdev -r 10 -i /dev/fb0 out.avi
-@end example
-
-You can take a single screenshot image with the command:
-@example
-ffmpeg -f fbdev -vframes 1 -r 1 -i /dev/fb0 screenshot.jpeg
-@end example
-
-See also @url{http://linux-fbdev.sourceforge.net/}, and fbset(1).
-
-@section jack
-
-JACK input device.
-
-To enable this input device during configuration you need libjack
-installed on your system.
-
-A JACK input device creates one or more JACK writable clients, one for
-each audio channel, with name @var{client_name}:input_@var{N}, where
-@var{client_name} is the name provided by the application, and @var{N}
-is a number which identifies the channel.
-Each writable client will send the acquired data to the FFmpeg input
-device.
-
-Once you have created one or more JACK readable clients, you need to
-connect them to one or more JACK writable clients.
-
-To connect or disconnect JACK clients you can use the
-@file{jack_connect} and @file{jack_disconnect} programs, or do it
-through a graphical interface, for example with @file{qjackctl}.
-
-To list the JACK clients and their properties you can invoke the command
-@file{jack_lsp}.
-
-Follows an example which shows how to capture a JACK readable client
-with @file{ffmpeg}.
-@example
-# Create a JACK writable client with name "ffmpeg".
-$ ffmpeg -f jack -i ffmpeg -y out.wav
-
-# Start the sample jack_metro readable client.
-$ jack_metro -b 120 -d 0.2 -f 4000
-
-# List the current JACK clients.
-$ jack_lsp -c
-system:capture_1
-system:capture_2
-system:playback_1
-system:playback_2
-ffmpeg:input_1
-metro:120_bpm
-
-# Connect metro to the ffmpeg writable client.
-$ jack_connect metro:120_bpm ffmpeg:input_1
-@end example
-
-For more information read:
-@url{http://jackaudio.org/}
-
-@section libdc1394
-
-IIDC1394 input device, based on libdc1394 and libraw1394.
-
-@section openal
-
-The OpenAL input device provides audio capture on all systems with a
-working OpenAL 1.1 implementation.
-
-To enable this input device during configuration, you need OpenAL
-headers and libraries installed on your system, and need to configure
-FFmpeg with @code{--enable-openal}.
-
-OpenAL headers and libraries should be provided as part of your OpenAL
-implementation, or as an additional download (an SDK). Depending on your
-installation you may need to specify additional flags via the
-@code{--extra-cflags} and @code{--extra-ldflags} for allowing the build
-system to locate the OpenAL headers and libraries.
-
-An incomplete list of OpenAL implementations follows:
-
-@table @strong
-@item Creative
-The official Windows implementation, providing hardware acceleration
-with supported devices and software fallback.
-See @url{http://openal.org/}.
-@item OpenAL Soft
-Portable, open source (LGPL) software implementation. Includes
-backends for the most common sound APIs on the Windows, Linux,
-Solaris, and BSD operating systems.
-See @url{http://kcat.strangesoft.net/openal.html}.
-@item Apple
-OpenAL is part of Core Audio, the official Mac OS X Audio interface.
-See @url{http://developer.apple.com/technologies/mac/audio-and-video.html}
-@end table
-
-This device allows to capture from an audio input device handled
-through OpenAL.
-
-You need to specify the name of the device to capture in the provided
-filename. If the empty string is provided, the device will
-automatically select the default device. You can get the list of the
-supported devices by using the option @var{list_devices}.
-
-@subsection Options
-
-@table @option
-
-@item channels
-Set the number of channels in the captured audio. Only the values
-@option{1} (monaural) and @option{2} (stereo) are currently supported.
-Defaults to @option{2}.
-
-@item sample_size
-Set the sample size (in bits) of the captured audio. Only the values
-@option{8} and @option{16} are currently supported. Defaults to
-@option{16}.
-
-@item sample_rate
-Set the sample rate (in Hz) of the captured audio.
-Defaults to @option{44.1k}.
-
-@item list_devices
-If set to @option{true}, print a list of devices and exit.
-Defaults to @option{false}.
-
-@end table
-
-@subsection Examples
-
-Print the list of OpenAL supported devices and exit:
-@example
-$ ffmpeg -list_devices true -f openal -i dummy out.ogg
-@end example
-
-Capture from the OpenAL device @file{DR-BT101 via PulseAudio}:
-@example
-$ ffmpeg -f openal -i 'DR-BT101 via PulseAudio' out.ogg
-@end example
-
-Capture from the default device (note the empty string '' as filename):
-@example
-$ ffmpeg -f openal -i '' out.ogg
-@end example
-
-Capture from two devices simultaneously, writing to two different files,
-within the same @file{ffmpeg} command:
-@example
-$ ffmpeg -f openal -i 'DR-BT101 via PulseAudio' out1.ogg -f openal -i 'ALSA Default' out2.ogg
-@end example
-Note: not all OpenAL implementations support multiple simultaneous capture -
-try the latest OpenAL Soft if the above does not work.
-
-@section oss
-
-Open Sound System input device.
-
-The filename to provide to the input device is the device node
-representing the OSS input device, and is usually set to
-@file{/dev/dsp}.
-
-For example to grab from @file{/dev/dsp} using @file{ffmpeg} use the
-command:
-@example
-ffmpeg -f oss -i /dev/dsp /tmp/oss.wav
-@end example
-
-For more information about OSS see:
-@url{http://manuals.opensound.com/usersguide/dsp.html}
-
-@section sndio
-
-sndio input device.
-
-To enable this input device during configuration you need libsndio
-installed on your system.
-
-The filename to provide to the input device is the device node
-representing the sndio input device, and is usually set to
-@file{/dev/audio0}.
-
-For example to grab from @file{/dev/audio0} using @file{ffmpeg} use the
-command:
-@example
-ffmpeg -f sndio -i /dev/audio0 /tmp/oss.wav
-@end example
-
-@section video4linux and video4linux2
-
-Video4Linux and Video4Linux2 input video devices.
-
-The name of the device to grab is a file device node, usually Linux
-systems tend to automatically create such nodes when the device
-(e.g. an USB webcam) is plugged into the system, and has a name of the
-kind @file{/dev/video@var{N}}, where @var{N} is a number associated to
-the device.
-
-Video4Linux and Video4Linux2 devices only support a limited set of
-@var{width}x@var{height} sizes and framerates. You can check which are
-supported for example with the command @file{dov4l} for Video4Linux
-devices and the command @file{v4l-info} for Video4Linux2 devices.
-
-If the size for the device is set to 0x0, the input device will
-try to autodetect the size to use.
-Only for the video4linux2 device, if the frame rate is set to 0/0 the
-input device will use the frame rate value already set in the driver.
-
-Video4Linux support is deprecated since Linux 2.6.30, and will be
-dropped in later versions.
-
-Follow some usage examples of the video4linux devices with the ff*
-tools.
-@example
-# Grab and show the input of a video4linux device, frame rate is set
-# to the default of 25/1.
-ffplay -s 320x240 -f video4linux /dev/video0
-
-# Grab and show the input of a video4linux2 device, autoadjust size.
-ffplay -f video4linux2 /dev/video0
-
-# Grab and record the input of a video4linux2 device, autoadjust size,
-# frame rate value defaults to 0/0 so it is read from the video4linux2
-# driver.
-ffmpeg -f video4linux2 -i /dev/video0 out.mpeg
-@end example
-
-@section vfwcap
-
-VfW (Video for Windows) capture input device.
-
-The filename passed as input is the capture driver number, ranging from
-0 to 9. You may use "list" as filename to print a list of drivers. Any
-other filename will be interpreted as device number 0.
-
-@section x11grab
-
-X11 video input device.
-
-This device allows to capture a region of an X11 display.
-
-The filename passed as input has the syntax:
-@example
-[@var{hostname}]:@var{display_number}.@var{screen_number}[+@var{x_offset},@var{y_offset}]
-@end example
-
-@var{hostname}:@var{display_number}.@var{screen_number} specifies the
-X11 display name of the screen to grab from. @var{hostname} can be
-ommitted, and defaults to "localhost". The environment variable
-@env{DISPLAY} contains the default display name.
-
-@var{x_offset} and @var{y_offset} specify the offsets of the grabbed
-area with respect to the top-left border of the X11 screen. They
-default to 0.
-
-Check the X11 documentation (e.g. man X) for more detailed information.
-
-Use the @file{dpyinfo} program for getting basic information about the
-properties of your X11 display (e.g. grep for "name" or "dimensions").
-
-For example to grab from @file{:0.0} using @file{ffmpeg}:
-@example
-ffmpeg -f x11grab -r 25 -s cif -i :0.0 out.mpg
-
-# Grab at position 10,20.
-ffmpeg -f x11grab -r 25 -s cif -i :0.0+10,20 out.mpg
-@end example
-
-@subsection @var{follow_mouse} AVOption
-
-The syntax is:
-@example
--follow_mouse centered|@var{PIXELS}
-@end example
-
-When it is specified with "centered", the grabbing region follows the mouse
-pointer and keeps the pointer at the center of region; otherwise, the region
-follows only when the mouse pointer reaches within @var{PIXELS} (greater than
-zero) to the edge of region.
-
-For example:
-@example
-ffmpeg -f x11grab -follow_mouse centered -r 25 -s cif -i :0.0 out.mpg
-
-# Follows only when the mouse pointer reaches within 100 pixels to edge
-ffmpeg -f x11grab -follow_mouse 100 -r 25 -s cif -i :0.0 out.mpg
-@end example
-
-@subsection @var{show_region} AVOption
-
-The syntax is:
-@example
--show_region 1
-@end example
-
-If @var{show_region} AVOption is specified with @var{1}, then the grabbing
-region will be indicated on screen. With this option, it's easy to know what is
-being grabbed if only a portion of the screen is grabbed.
-
-For example:
-@example
-ffmpeg -f x11grab -show_region 1 -r 25 -s cif -i :0.0+10,20 out.mpg
-
-# With follow_mouse
-ffmpeg -f x11grab -follow_mouse centered -show_region 1  -r 25 -s cif -i :0.0 out.mpg
-@end example

+@chapter Available video filters
+
+When you configure your FFmpeg build, you can disable any of the
+existing video filters.
+The configure output will show the video filters included in your
+build.
+
+Below is a description of the currently available video filters.
+
+@section crop
+
+Crop the input video to @var{x}:@var{y}:@var{width}:@var{height}.
+
+@example
+./ffmpeg -i in.avi -vfilters "crop=0:0:0:240" out.avi
+@end example
+
+@var{x} and @var{y} specify the position of the top-left corner of the
+output (non-cropped) area.
+
+The default value of @var{x} and @var{y} is 0.
+
+The @var{width} and @var{height} parameters specify the width and height
+of the output (non-cropped) area.
+
+A value of 0 is interpreted as the maximum possible size contained in
+the area delimited by the top-left corner at position x:y.
+
+For example the parameters:
+
+@example
+"crop=100:100:0:0"
+@end example
+
+will delimit the rectangle with the top-left corner placed at position
+100:100 and the right-bottom corner corresponding to the right-bottom
+corner of the input image.
+
+The default value of @var{width} and @var{height} is 0.
+
+@section format
+
+Convert the input video to one of the specified pixel formats.
+Libavfilter will try to pick one that is supported for the input to
+the next filter.
+
+The filter accepts a list of pixel format names, separated by ``:'',
+for example ``yuv420p:monow:rgb24''.
+
+The following command:
+
+@example
+./ffmpeg -i in.avi -vfilters "format=yuv420p" out.avi
+@end example
+
+will convert the input video to the format ``yuv420p''.
+
+@section noformat
+
+Force libavfilter not to use any of the specified pixel formats for the
+input to the next filter.
+
+The filter accepts a list of pixel format names, separated by ``:'',
+for example ``yuv420p:monow:rgb24''.
+
+The following command:
+
+@example
+./ffmpeg -i in.avi -vfilters "noformat=yuv420p, vflip" out.avi
+@end example
+
+will make libavfilter use a format different from ``yuv420p'' for the
+input to the vflip filter.
+
+@section null
+
+Pass the source unchanged to the output.
+
+@section scale
+
+Scale the input video to @var{width}:@var{height} and/or convert the image format.
+
+For example the command:
+
+@example
+./ffmpeg -i in.avi -vfilters "scale=200:100" out.avi
+@end example
+
+will scale the input video to a size of 200x100.
+
+If the input image format is different from the format requested by
+the next filter, the scale filter will convert the input to the
+requested format.
+
+If the value for @var{width} or @var{height} is 0, the respective input
+size is used for the output.
+
+If the value for @var{width} or @var{height} is -1, the scale filter will
+use, for the respective output size, a value that maintains the aspect
+ratio of the input image.
+
+The default value of @var{width} and @var{height} is 0.
+
+@section slicify
+
+Pass the images of input video on to next video filter as multiple
+slices.
+
+@example
+./ffmpeg -i in.avi -vfilters "slicify=32" out.avi
+@end example
+
+The filter accepts the slice height as parameter. If the parameter is
+not specified it will use the default value of 16.
+
+Adding this in the beginning of filter chains should make filtering
+faster due to better use of the memory cache.
+
+@section unsharp
+
+Sharpen or blur the input video. It accepts the following parameters:
+
+@multitable @columnfractions .2 .5 .1 .1 .1
+@headitem Name @tab Description @tab Min @tab Max @tab Default
+@item @var{luma_msize_x}

-
-The file format is as follows:
-@enumerate
-
-@item
-A file consists of a header and a number of metadata tags divided into sections,
-each on its own line.
-
-@item
-The header is a ';FFMETADATA' string, followed by a version number (now 1).

-Immediately after header follows global metadata
-

-After global metadata there may be sections with per-stream/per-chapter
-metadata.
-
-@item
-A section starts with the section name in uppercase (i.e. STREAM or CHAPTER) in
-brackets ('[', ']') and ends with next section or end of file.
-
-@item
-At the beginning of a chapter section there may be an optional timebase to be
-used for start/end values. It must be in form 'TIMEBASE=num/den', where num and

-FFmpeg multithreading methods
-==============================================
-
-FFmpeg provides two methods for multithreading codecs.
-
-Slice threading decodes multiple parts of a frame at the same time, using
-AVCodecContext execute() and execute2().
-
-Frame threading decodes multiple frames at the same time.
-It accepts N future frames and delays decoded pictures by N-1 frames.
-The later frames are decoded in separate threads while the user is
-displaying the current one.
-
-Restrictions on clients
-==============================================
-
-Slice threading -
-* The client's draw_horiz_band() must be thread-safe according to the comment
-  in avcodec.h.
-
-Frame threading -
-* Restrictions with slice threading also apply.
-* For best performance, the client should set thread_safe_callbacks if it
-  provides a thread-safe get_buffer() callback.
-* There is one frame of delay added for every thread beyond the first one.
-  Clients must be able to handle this; the pkt_dts and pkt_pts fields in
-  AVFrame will work as usual.
-
-Restrictions on codec implementations
-==============================================
-
-Slice threading -
- None except that there must be something worth executing in parallel.
-
-Frame threading -
-* Codecs can only accept entire pictures per packet.
-* Codecs similar to ffv1, whose streams don't reset across frames,
-  will not work because their bitstreams cannot be decoded in parallel.
-
-* The contents of buffers must not be read before ff_thread_await_progress()
-  has been called on them. reget_buffer() and buffer age optimizations no longer work.
-* The contents of buffers must not be written to after ff_thread_report_progress()
-  has been called on them. This includes draw_edges().
-
-Porting codecs to frame threading
-==============================================
-
-Find all context variables that are needed by the next frame. Move all
-code changing them, as well as code calling get_buffer(), up to before
-the decode process starts. Call ff_thread_finish_setup() afterwards. If
-some code can't be moved, have update_thread_context() run it in the next
-thread.
-
-If the codec allocates writable tables in its init(), add an init_thread_copy()
-which re-allocates them for other threads.
-
-Add CODEC_CAP_FRAME_THREADS to the codec capabilities. There will be very little
-speed gain at this point but it should work.
-
-Call ff_thread_report_progress() after some part of the current picture has decoded.
-A good place to put this is where draw_horiz_band() is called - add this if it isn't
-called anywhere, as it's useful too and the implementation is trivial when you're
-doing this. Note that draw_edges() needs to be called before reporting progress.
-
-Before accessing a reference frame or its MVs, call ff_thread_await_progress().

-
-Muxers are configured elements in FFmpeg which allow writing
-multimedia streams to a particular type of file.
-
-When you configure your FFmpeg build, all the supported muxers
-are enabled by default. You can list all available muxers using the
-configure option @code{--list-muxers}.
-
-You can disable all the muxers with the configure option
-@code{--disable-muxers} and selectively enable / disable single muxers
-with the options @code{--enable-muxer=@var{MUXER}} /
-@code{--disable-muxer=@var{MUXER}}.
-
-The option @code{-formats} of the ff* tools will display the list of
-enabled muxers.
-
-A description of some of the currently available muxers follows.
-
-@anchor{crc}
-@section crc
-
-CRC (Cyclic Redundancy Check) testing format.
-
-This muxer computes and prints the Adler-32 CRC of all the input audio
-and video frames. By default audio frames are converted to signed
-16-bit raw audio and video frames to raw video before computing the
-CRC.
-
-The output of the muxer consists of a single line of the form:
-CRC=0x@var{CRC}, where @var{CRC} is a hexadecimal number 0-padded to
-8 digits containing the CRC for all the decoded input frames.
-
-For example to compute the CRC of the input, and store it in the file
-@file{out.crc}:
-@example
-ffmpeg -i INPUT -f crc out.crc
-@end example
-
-You can print the CRC to stdout with the command:
-@example
-ffmpeg -i INPUT -f crc -
-@end example
-
-You can select the output format of each frame with @file{ffmpeg} by
-specifying the audio and video codec and format. For example to
-compute the CRC of the input audio converted to PCM unsigned 8-bit
-and the input video converted to MPEG-2 video, use the command:
-@example
-ffmpeg -i INPUT -acodec pcm_u8 -vcodec mpeg2video -f crc -
-@end example
-
-See also the @ref{framecrc} muxer.
-
-@anchor{framecrc}

-
-Per-frame CRC (Cyclic Redundancy Check) testing format.
-
-This muxer computes and prints the Adler-32 CRC for each decoded audio
-and video frame. By default audio frames are converted to signed
-16-bit raw audio and video frames to raw video before computing the
-CRC.
-
-The output of the muxer consists of a line for each audio and video
-frame of the form: @var{stream_index}, @var{frame_dts},
-@var{frame_size}, 0x@var{CRC}, where @var{CRC} is a hexadecimal

-
-See also the @ref{crc} muxer.
-
-@section image2
-
-Image file muxer.
-
-The image file muxer writes video frames to image files.
-
-The output filenames are specified by a pattern, which can be used to
-produce sequentially numbered series of files.
-The pattern may contain the string "%d" or "%0@var{N}d", this string
-specifies the position of the characters representing a numbering in
-the filenames. If the form "%0@var{N}d" is used, the string
-representing the number in each filename is 0-padded to @var{N}
-digits. The literal character '%' can be specified in the pattern with
-the string "%%".
-
-If the pattern contains "%d" or "%0@var{N}d", the first filename of
-the file list specified will contain the number 1, all the following
-numbers will be sequential.
-
-The pattern may contain a suffix which is used to automatically
-determine the format of the image files to write.
-
-For example the pattern "img-%03d.bmp" will specify a sequence of
-filenames of the form @file{img-001.bmp}, @file{img-002.bmp}, ...,
-@file{img-010.bmp}, etc.
-The pattern "img%%-%d.jpg" will specify a sequence of filenames of the
-form @file{img%-1.jpg}, @file{img%-2.jpg}, ..., @file{img%-10.jpg},
-etc.
-
-The following example shows how to use @file{ffmpeg} for creating a
-sequence of files @file{img-001.jpeg}, @file{img-002.jpeg}, ...,
-taking one image every second from the input video:
-@example
-ffmpeg -i in.avi -r 1 -f image2 'img-%03d.jpeg'
-@end example
-
-Note that with @file{ffmpeg}, if the format is not specified with the
-@code{-f} option and the output filename specifies an image file
-format, the image2 muxer is automatically selected, so the previous
-command can be written as:
-@example
-ffmpeg -i in.avi -r 1 'img-%03d.jpeg'
-@end example
-
-Note also that the pattern must not necessarily contain "%d" or
-"%0@var{N}d", for example to create a single image file
-@file{img.jpeg} from the input video you can employ the command:
-@example
-ffmpeg -i in.avi -f image2 -vframes 1 img.jpeg
-@end example
-
-The image muxer supports the .Y.U.V image file format. This format is
-special in that that each image frame consists of three files, for
-each of the YUV420P components. To read or write this image file format,
-specify the name of the '.Y' file. The muxer will automatically open the
-'.U' and '.V' files as required.
-
-@section mpegts
-
-MPEG transport stream muxer.
-
-This muxer implements ISO 13818-1 and part of ETSI EN 300 468.
-
-The muxer options are:

-@end example
-
-@section md5
-
-MD5 output protocol.
-
-Computes the MD5 hash of the data to be written, and on close writes
-this to the designated output or stdout if none is specified. It can
-be used to test muxers without writing an actual file.
-
-Some examples follow.
-@example
-# Write the MD5 hash of the encoded AVI file to the file output.avi.md5.
-ffmpeg -i input.flv -f avi -y md5:output.avi.md5
-
-# Write the MD5 hash of the encoded AVI file to stdout.
-ffmpeg -i input.flv -f avi -y md5:
-@end example
-
-Note that some formats (typically MOV) require the output protocol to
-be seekable, so they will fail with the MD5 output protocol.
-
-@section pipe
-
-UNIX pipe access protocol.
-
-Allow to read and write from UNIX pipes.
-
-The accepted syntax is:
-@example
-pipe:[@var{number}]
-@end example
-
-@var{number} is the number corresponding to the file descriptor of the
-pipe (e.g. 0 for stdin, 1 for stdout, 2 for stderr).  If @var{number}
-is not specified, by default the stdout file descriptor will be used
-for writing, stdin for reading.
-
-For example to read from stdin with @file{ffmpeg}:
-@example
-cat test.wav | ffmpeg -i pipe:0
-# ...this is the same as...
-cat test.wav | ffmpeg -i pipe:
-@end example
-
-For writing to stdout with @file{ffmpeg}:
-@example
-ffmpeg -i test.wav -f avi pipe:1 | cat > test.avi
-# ...this is the same as...
-ffmpeg -i test.wav -f avi pipe: | cat > test.avi

-@section rtmp
-
-Real-Time Messaging Protocol.
-
-The Real-Time Messaging Protocol (RTMP) is used for streaming multime‐
-dia content across a TCP/IP network.
-
-The required syntax is:
-@example
-rtmp://@var{server}[:@var{port}][/@var{app}][/@var{playpath}]
-@end example
-
-The accepted parameters are:
-@table @option
-
-@item server
-The address of the RTMP server.
-
-@item port
-The number of the TCP port to use (by default is 1935).
-
-@item app
-It is the name of the application to access. It usually corresponds to
-the path where the application is installed on the RTMP server
-(e.g. @file{/ondemand/}, @file{/flash/live/}, etc.).
-
-@item playpath
-It is the path or name of the resource to play with reference to the
-application specified in @var{app}, may be prefixed by "mp4:".
-
-@end table
-
-For example to read with @file{ffplay} a multimedia resource named
-"sample" from the application "vod" from an RTMP server "myserver":
-@example
-ffplay rtmp://myserver/vod/sample
-@end example
-
-@section rtmp, rtmpe, rtmps, rtmpt, rtmpte
-
-Real-Time Messaging Protocol and its variants supported through
-librtmp.
-
-Requires the presence of the librtmp headers and library during
-configuration. You need to explicitely configure the build with
-"--enable-librtmp". If enabled this will replace the native RTMP
-protocol.
-
-This protocol provides most client functions and a few server
-functions needed to support RTMP, RTMP tunneled in HTTP (RTMPT),
-encrypted RTMP (RTMPE), RTMP over SSL/TLS (RTMPS) and tunneled
-variants of these encrypted types (RTMPTE, RTMPTS).
-
-The required syntax is:
-@example
-@var{rtmp_proto}://@var{server}[:@var{port}][/@var{app}][/@var{playpath}] @var{options}
-@end example
-
-where @var{rtmp_proto} is one of the strings "rtmp", "rtmpt", "rtmpe",
-"rtmps", "rtmpte", "rtmpts" corresponding to each RTMP variant, and
-@var{server}, @var{port}, @var{app} and @var{playpath} have the same
-meaning as specified for the RTMP native protocol.
-@var{options} contains a list of space-separated options of the form
-@var{key}=@var{val}.
-
-See the librtmp manual page (man 3 librtmp) for more information.
-
-For example, to stream a file in real-time to an RTMP server using
-@file{ffmpeg}:
-@example
-ffmpeg -re -i myfile -f flv rtmp://myserver/live/mystream
-@end example
-
-To play the same stream using @file{ffplay}:
-@example
-ffplay "rtmp://myserver/live/mystream live=1"
-@end example
-
-@section rtp
-
-Real-Time Protocol.
-
-@section rtsp
-
-RTSP is not technically a protocol handler in libavformat, it is a demuxer
-and muxer. The demuxer supports both normal RTSP (with data transferred
-over RTP; this is used by e.g. Apple and Microsoft) and Real-RTSP (with
-data transferred over RDT).
-
-The muxer can be used to send a stream using RTSP ANNOUNCE to a server
-supporting it (currently Darwin Streaming Server and Mischa Spiegelmock's
-@uref{http://github.com/revmischa/rtsp-server, RTSP server}).
-
-The required syntax for a RTSP url is:
-@example
-rtsp://@var{hostname}[:@var{port}]/@var{path}[?@var{options}]
-@end example
-
-@var{options} is a @code{&}-separated list. The following options
-are supported:
-
-@table @option
-
-@item udp
-Use UDP as lower transport protocol.
-
-@item tcp
-Use TCP (interleaving within the RTSP control channel) as lower
-transport protocol.
-
-@item multicast
-Use UDP multicast as lower transport protocol.
-
-@item http
-Use HTTP tunneling as lower transport protocol, which is useful for
-passing proxies.
-
-@item filter_src
-Accept packets only from negotiated peer address and port.
-@end table
-
-Multiple lower transport protocols may be specified, in that case they are
-tried one at a time (if the setup of one fails, the next one is tried).
-For the muxer, only the @code{tcp} and @code{udp} options are supported.
-
-When receiving data over UDP, the demuxer tries to reorder received packets
-(since they may arrive out of order, or packets may get lost totally). In
-order for this to be enabled, a maximum delay must be specified in the
-@code{max_delay} field of AVFormatContext.
-
-When watching multi-bitrate Real-RTSP streams with @file{ffplay}, the
-streams to display can be chosen with @code{-vst} @var{n} and
-@code{-ast} @var{n} for video and audio respectively, and can be switched
-on the fly by pressing @code{v} and @code{a}.
-
-Example command lines:
-
-To watch a stream over UDP, with a max reordering delay of 0.5 seconds:
-
-@example
-ffplay -max_delay 500000 rtsp://server/video.mp4?udp
-@end example
-
-To watch a stream tunneled over HTTP:
-
-@example
-ffplay rtsp://server/video.mp4?http
-@end example
-
-To send a stream in realtime to a RTSP server, for others to watch:
-
-@example
-ffmpeg -re -i @var{input} -f rtsp -muxdelay 0.1 rtsp://server/live.sdp
-@end example
-
-@section sap
-
-Session Announcement Protocol (RFC 2974). This is not technically a
-protocol handler in libavformat, it is a muxer and demuxer.
-It is used for signalling of RTP streams, by announcing the SDP for the
-streams regularly on a separate port.
-
-@subsection Muxer
-
-The syntax for a SAP url given to the muxer is:
-@example
-sap://@var{destination}[:@var{port}][?@var{options}]
-@end example
-
-The RTP packets are sent to @var{destination} on port @var{port},
-or to port 5004 if no port is specified.
-@var{options} is a @code{&}-separated list. The following options
-are supported:
-
-@table @option
-
-@item announce_addr=@var{address}
-Specify the destination IP address for sending the announcements to.
-If omitted, the announcements are sent to the commonly used SAP
-announcement multicast address 224.2.127.254 (sap.mcast.net), or
-ff0e::2:7ffe if @var{destination} is an IPv6 address.
-
-@item announce_port=@var{port}
-Specify the port to send the announcements on, defaults to
-9875 if not specified.
-
-@item ttl=@var{ttl}
-Specify the time to live value for the announcements and RTP packets,
-defaults to 255.
-
-@item same_port=@var{0|1}
-If set to 1, send all RTP streams on the same port pair. If zero (the
-default), all streams are sent on unique ports, with each stream on a
-port 2 numbers higher than the previous.
-VLC/Live555 requires this to be set to 1, to be able to receive the stream.
-The RTP stack in libavformat for receiving requires all streams to be sent
-on unique ports.
-@end table
-
-Example command lines follow.
-
-To broadcast a stream on the local subnet, for watching in VLC:
-
-@example
-ffmpeg -re -i @var{input} -f sap sap://224.0.0.255?same_port=1
-@end example
-
-Similarly, for watching in ffplay:
-
-@example
-ffmpeg -re -i @var{input} -f sap sap://224.0.0.255
-@end example
-
-And for watching in ffplay, over IPv6:
-
-@example
-ffmpeg -re -i @var{input} -f sap sap://[ff0e::1:2:3:4]
-@end example
-
-@subsection Demuxer
-
-The syntax for a SAP url given to the demuxer is:
-@example
-sap://[@var{address}][:@var{port}]
-@end example
-
-@var{address} is the multicast address to listen for announcements on,
-if omitted, the default 224.2.127.254 (sap.mcast.net) is used. @var{port}
-is the port that is listened on, 9875 if omitted.
-
-The demuxers listens for announcements on the given address and port.
-Once an announcement is received, it tries to receive that particular stream.
-
-Example command lines follow.
-
-To play back the first stream announced on the normal SAP multicast address:
-
-@example
-ffplay sap://
-@end example
-
-To play back the first stream announced on one the default IPv6 SAP multicast address:
-
-@example
-ffplay sap://[ff0e::2:7ffe]
-@end example
-
-@section tcp
-
-Trasmission Control Protocol.
-
-The required syntax for a TCP url is:
-@example
-tcp://@var{hostname}:@var{port}[?@var{options}]
-@end example
-
-@table @option
-
-@item listen
-Listen for an incoming connection
-
-@example
-ffmpeg -i @var{input} -f @var{format} tcp://@var{hostname}:@var{port}?listen
-ffplay tcp://@var{hostname}:@var{port}
-@end example
-
-@end table
-
-@section udp
-
-User Datagram Protocol.
-
-The required syntax for a UDP url is:
-@example
-udp://@var{hostname}:@var{port}[?@var{options}]
-@end example
-
-@var{options} contains a list of &-seperated options of the form @var{key}=@var{val}.
-Follow the list of supported options.
-
-@table @option
-
-@item buffer_size=@var{size}
-set the UDP buffer size in bytes
-
-@item localport=@var{port}
-override the local UDP port to bind with
-
-@item pkt_size=@var{size}
-set the size in bytes of UDP packets
-
-@item reuse=@var{1|0}
-explicitly allow or disallow reusing UDP sockets
-
-@item ttl=@var{ttl}
-set the time to live value (for multicast only)
-
-@item connect=@var{1|0}
-Initialize the UDP socket with @code{connect()}. In this case, the
-destination address can't be changed with ff_udp_set_remote_url later.
-If the destination address isn't known at the start, this option can
-be specified in ff_udp_set_remote_url, too.
-This allows finding out the source address for the packets with getsockname,
-and makes writes return with AVERROR(ECONNREFUSED) if "destination
-unreachable" is received.
-For receiving, this gives the benefit of only receiving packets from
-the specified peer address/port.
-@end table
-
-Some usage examples of the udp protocol with @file{ffmpeg} follow.
-
-To stream over UDP to a remote endpoint:
-@example
-ffmpeg -i @var{input} -f @var{format} udp://@var{hostname}:@var{port}
-@end example
-
-To stream in mpegts format over UDP using 188 sized UDP packets, using a large input buffer:
-@example
-ffmpeg -i @var{input} -f mpegts udp://@var{hostname}:@var{port}?pkt_size=188&buffer_size=65535
-@end example
-
-To receive over UDP from a remote endpoint:
-@example
-ffmpeg -i udp://[@var{multicast-address}]:@var{port}
-@end example
