+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.

+@section concat
+
+Virtual concatenation script demuxer.
+
+This demuxer reads a list of files and other directives from a text file and
+demuxes them one after the other, as if all their packet had been muxed
+together.
+
+The timestamps in the files are adjusted so that the first file starts at 0
+and each next file starts where the previous one finishes. Note that it is
+done globally and may cause gaps if all streams do not have exactly the same
+length.
+
+All files must have the same streams (same codecs, same time base, etc.).
+
+The duration of each file is used to adjust the timestamps of the next file:
+if the duration is incorrect (because it was computed using the bit-rate or
+because the file is truncated, for example), it can cause artifacts. The
+@code{duration} directive can be used to override the duration stored in
+each file.
+
+@subsection Syntax
+
+The script is a text file in extended-ASCII, with one directive per line.
+Empty lines, leading spaces and lines starting with '#' are ignored. The
+following directive is recognized:
+
+@table @option
+
+@item @code{file @var{path}}
+Path to a file to read; special characters and spaces must be escaped with
+backslash or single quotes.
+
+All subsequent directives apply to that file.
+
+@item @code{ffconcat version 1.0}
+Identify the script type and version. It also sets the @option{safe} option
+to 1 if it was to its default -1.
+
+To make FFmpeg recognize the format automatically, this directive must
+appears exactly as is (no extra space or byte-order-mark) on the very first
+line of the script.
+
+@item @code{duration @var{dur}}
+Duration of the file. This information can be specified from the file;
+specifying it here may be more efficient or help if the information from the
+file is not available or accurate.
+
+@end table
+
+@subsection Options
+
+This demuxer accepts the following option:
+
+@table @option
+
+@item safe
+If set to 1, reject unsafe file paths. A file path is considered safe if it
+does not contain a protocol specification and is relative and all components
+only contain characters from the portable character set (letters, digits,
+period, underscore and hyphen) and have no period at the beginning of a
+component.
+
+If set to 0, any file name is accepted.
+
+The default is -1, it is equivalent to 1 if the format was automatically
+probed and 0 otherwise.

+Advanced Audio Coding (AAC) encoder.
+
+This encoder is an experimental FFmpeg-native AAC encoder. Currently only the
+low complexity (AAC-LC) profile is supported. To use this encoder, you must set
+@option{strict} option to @samp{experimental} or lower.
+
+As this encoder is experimental, unexpected behavior may exist from time to
+time. For a more stable AAC encoder, see @ref{libvo-aacenc}. However, be warned
+that it has a worse quality reported by some users.
+
+@c Comment this out until somebody writes the respective documentation.
+@c See also @ref{libfaac}, @ref{libaacplus}, and @ref{libfdk-aac-enc}.

+FAAC-inspired method.
+
+This method is a simplified reimplementation of the method used in FAAC, which
+sets thresholds proportional to the band energies, and then decreases all the
+thresholds with quantizer steps to find the appropriate quantization with
+distortion below threshold band by band.
+
+The quality of this method is comparable to the two loop searching method
+descibed below, but somewhat a little better and slower.
+
+@item 1
+Average noise to mask ratio (ANMR) trellis-based solution.
+
+This has a theoretic best quality out of all the coding methods, but at the
+cost of the slowest speed.
+
+@item 2
+Two loop searching (TLS) method.
+
+This method first sets quantizers depending on band thresholds and then tries
+to find an optimal combination by adding or subtracting a specific value from
+all quantizers and adjusting some individual quantizer a little.
+
+This method produces similar quality with the FAAC method and is the default.

+that you have them installed and working on your system.
+
+
+1) Build the installed examples in a generic read/write user directory
+
+Copy to a read/write user directory and just use "make", it will link
+to the libraries on your system, assuming the PKG_CONFIG_PATH is
+correctly configured.
+
+2) Build the examples in-tree
+
+Assuming you are in the source FFmpeg checkout directory, you need to build
+FFmpeg (no need to make install in any prefix). Then you can go into the
+doc/examples and run a command such as PKG_CONFIG_PATH=pc-uninstalled make.

+

+Possible values:
+@table @samp
+@item direct
+Reduce buffering.
+@end table
+
+@item probesize @var{integer} (@emph{input})
+Set probing size in bytes, i.e. the size of the data to analyze to get
+stream information. A higher value will allow to detect more
+information in case it is dispersed into the stream, but will increase
+latency. Must be an integer not lesser than 32. It is 5000000 by default.
+
+@item packetsize @var{integer} (@emph{output})
+Set packet size.
+
+@item fflags @var{flags} (@emph{input/output})
+Set format flags.
+
+Possible values:
+@table @samp
+@item ignidx
+Ignore index.
+@item genpts
+Generate PTS.
+@item nofillin
+Do not fill in missing values that can be exactly calculated.
+@item noparse
+Disable AVParsers, this needs @code{+nofillin} too.

+
+The FFmpeg resampler provides an high-level interface to the
+libswresample library audio resampling utilities. In particular it
+allows to perform audio resampling, audio channel layout rematrixing,
+and convert audio format and packing layout.
+
+@c man end DESCRIPTION
+
+@chapter Resampler Options
+@c man begin RESAMPLER OPTIONS
+
+The audio resampler supports the following named options.
+
+Options may be set by specifying -@var{option} @var{value} in the
+FFmpeg tools, @var{option}=@var{value} for the aresample filter,
+by setting the value explicitly in the
+@code{SwrContext} options or using the @file{libavutil/opt.h} API for
+programmatic use.
+
+@table @option
+
+@item ich, in_channel_count
+Set the number of input channels. Default value is 0. Setting this
+value is not mandatory if the corresponding channel layout
+@option{in_channel_layout} is set.
+
+@item och, out_channel_count
+Set the number of output channels. Default value is 0. Setting this
+value is not mandatory if the corresponding channel layout
+@option{out_channel_layout} is set.
+
+@item uch, used_channel_count
+Set the number of used input channels. Default value is 0. This option is
+only used for special remapping.
+
+@item isr, in_sample_rate
+Set the input sample rate. Default value is 0.
+
+@item osr, out_sample_rate
+Set the output sample rate. Default value is 0.
+
+@item isf, in_sample_fmt
+Specify the input sample format. It is set by default to @code{none}.
+
+@item osf, out_sample_fmt
+Specify the output sample format. It is set by default to @code{none}.
+
+@item tsf, internal_sample_fmt
+Set the internal sample format. Default value is @code{none}.
+This will automatically be chosen when it is not explicitly set.
+
+@item icl, in_channel_layout
+Set the input channel layout.
+
+@item ocl, out_channel_layout
+Set the output channel layout.
+
+@item clev, center_mix_level
+Set the center mix level. It is a value expressed in deciBel, and must be
+in the interval [-32,32].
+
+@item slev, surround_mix_level
+Set the surround mix level. It is a value expressed in deciBel, and must
+be in the interval [-32,32].
+
+@item lfe_mix_level
+Set LFE mix into non LFE level. It is used when there is a LFE input but no
+LFE output. It is a value expressed in deciBel, and must
+be in the interval [-32,32].
+
+@item rmvol, rematrix_volume
+Set rematrix volume. Default value is 1.0.
+
+@item flags, swr_flags
+Set flags used by the converter. Default value is 0.
+
+It supports the following individual flags:
+@table @option
+@item res
+force resampling, this flag forces resampling to be used even when the
+input and output sample rates match.
+@end table
+
+@item dither_scale
+Set the dither scale. Default value is 1.
+
+@item dither_method
+Set dither method. Default value is 0.
+
+Supported values:
+@table @samp
+@item rectangular
+select rectangular dither
+@item triangular
+select triangular dither
+@item triangular_hp
+select triangular dither with high pass
+@item lipshitz
+select lipshitz noise shaping dither
+@item shibata
+select shibata noise shaping dither
+@item low_shibata
+select low shibata noise shaping dither
+@item high_shibata
+select high shibata noise shaping dither
+@item f_weighted
+select f-weighted noise shaping dither
+@item modified_e_weighted
+select modified-e-weighted noise shaping dither
+@item improved_e_weighted
+select improved-e-weighted noise shaping dither
+
+@end table
+
+@item resampler
+Set resampling engine. Default value is swr.
+
+Supported values:
+@table @samp
+@item swr
+select the native SW Resampler; filter options precision and cheby are not
+applicable in this case.
+@item soxr
+select the SoX Resampler (where available); compensation, and filter options
+filter_size, phase_shift, filter_type & kaiser_beta, are not applicable in this
+case.
+@end table
+
+@item filter_size
+For swr only, set resampling filter size, default value is 32.
+
+@item phase_shift
+For swr only, set resampling phase shift, default value is 10, and must be in
+the interval [0,30].
+
+@item linear_interp
+Use Linear Interpolation if set to 1, default value is 0.
+
+@item cutoff
+Set cutoff frequency (swr: 6dB point; soxr: 0dB point) ratio; must be a float
+value between 0 and 1.  Default value is 0.97 with swr, and 0.91 with soxr
+(which, with a sample-rate of 44100, preserves the entire audio band to 20kHz).
+
+@item precision
+For soxr only, the precision in bits to which the resampled signal will be
+calculated.  The default value of 20 (which, with suitable dithering, is
+appropriate for a destination bit-depth of 16) gives SoX's 'High Quality'; a
+value of 28 gives SoX's 'Very High Quality'.
+
+@item cheby
+For soxr only, selects passband rolloff none (Chebyshev) & higher-precision
+approximation for 'irrational' ratios. Default value is 0.
+
+@item async
+For swr only, simple 1 parameter audio sync to timestamps using stretching,
+squeezing, filling and trimming. Setting this to 1 will enable filling and
+trimming, larger values represent the maximum amount in samples that the data
+may be stretched or squeezed for each second.
+Default value is 0, thus no compensation is applied to make the samples match
+the audio timestamps.
+
+@item first_pts
+For swr only, assume the first pts should be this value. The time unit is 1 / sample rate.
+This allows for padding/trimming at the start of stream. By default, no
+assumption is made about the first frame's expected pts, so no padding or
+trimming is done. For example, this could be set to 0 to pad the beginning with
+silence if an audio stream starts after the video stream or to trim any samples
+with a negative pts due to encoder delay.
+
+@item min_comp
+For swr only, set the minimum difference between timestamps and audio data (in
+seconds) to trigger stretching/squeezing/filling or trimming of the
+data to make it match the timestamps. The default is that
+stretching/squeezing/filling and trimming is disabled
+(@option{min_comp} = @code{FLT_MAX}).
+
+@item min_hard_comp
+For swr only, set the minimum difference between timestamps and audio data (in
+seconds) to trigger adding/dropping samples to make it match the
+timestamps.  This option effectively is a threshold to select between
+hard (trim/fill) and soft (squeeze/stretch) compensation. Note that
+all compensation is by default disabled through @option{min_comp}.
+The default is 0.1.
+
+@item comp_duration
+For swr only, set duration (in seconds) over which data is stretched/squeezed
+to make it match the timestamps. Must be a non-negative double float value,
+default value is 1.0.
+
+@item max_soft_comp
+For swr only, set maximum factor by which data is stretched/squeezed to make it
+match the timestamps. Must be a non-negative double float value, default value
+is 0.
+
+@item matrix_encoding
+Select matrixed stereo encoding.
+
+It accepts the following values:
+@table @samp
+@item none
+select none
+@item dolby
+select Dolby
+@item dplii
+select Dolby Pro Logic II
+@end table
+
+Default value is @code{none}.
+
+@item filter_type
+For swr only, select resampling filter type. This only affects resampling
+operations.
+
+It accepts the following values:
+@table @samp
+@item cubic
+select cubic
+@item blackman_nuttall
+select Blackman Nuttall Windowed Sinc
+@item kaiser
+select Kaiser Windowed Sinc
+@end table
+
+@item kaiser_beta
+For swr only, set Kaiser Window Beta value. Must be an integer in the
+interval [2,16], default value is 9.

+@section What is FFM, FFM2
+
+FFM and FFM2 are formats used by ffserver. They allow storing a wide variety of
+video and audio streams and encoding options, and can store a moving time segment
+of an infinite movie or a whole movie.
+
+FFM is version specific, and there is limited compatibility of FFM files
+generated by one version of ffmpeg/ffserver and another version of
+ffmpeg/ffserver. It may work but it is not guaranteed to work.
+
+FFM2 is extensible while maintaining compatibility and should work between
+differing versions of tools. FFM2 is the default.

+
+@item
+@emph{Rematrixing}: is the process of changing the channel layout, for

+It is different from specifying several outputs to the @command{ffmpeg}

+useful when using the libavformat API directly because it is then possible
+to feed the same packets to several muxers directly.
+
+The slave outputs are specified in the file name given to the muxer,

+must be escaped; note that this is a second level escaping.

+@section Generic raw YUVA formats
+
+Since many exotic planar YUVA pixel formats are not considered by
+the AVI/QuickTime FourCC lists, the following scheme is adopted for
+representing them.
+
+The first two bytes can contain the values:
+Y1 = only Y
+Y2 = Y+A
+Y3 = YUV
+Y4 = YUVA
+
+The third byte represents the width and height chroma subsampling
+values for the UV planes, that is the amount to shift the luma
+width/height right to find the chroma width/height.
+
+The fourth byte is the number of bits used (8, 16, ...).
+
+If the order of bytes is inverted, that means that each component has
+to be read big-endian.

-you might have to modify the procedures slightly.
+You will need the following prerequisites:

-@enumerate
+Place @code{makedef}, @code{c99wrap.exe}, @code{c99conv.exe}, and @code{yasm.exe}
+somewhere in your @code{PATH}.

-@item Create a new console application ("File / New / Project") and then
-select "Win32 Console Application". On the appropriate page of the
-Application Wizard, uncheck the "Precompiled headers" option.
+Next, make sure @code{inttypes.h} and any other headers and libs you want to use
+are located in a spot that MSVC can see. Do so by modifying the @code{LIB} and
+@code{INCLUDE} environment variables to include the @strong{Windows} paths to
+these directories. Alternatively, you can try and use the
+@code{--extra-cflags}/@code{--extra-ldflags} configure options.

-@item Write the source code for your application, or, for testing, just
-copy the code from an existing sample application into the source file
-that MSVC++ has already created for you. For example, you can copy
-@file{libavformat/output-example.c} from the FFmpeg distribution.
-
-@item Open the "Project / Properties" dialog box. In the "Configuration"
-combo box, select "All Configurations" so that the changes you make will
-affect both debug and release builds. In the tree view on the left hand
-side, select "C/C++ / General", then edit the "Additional Include

-installed (i.e. @file{c:\msys\1.0\local\include}).
-Do not add MinGW's include directory here, or the include files will

-
-@item Still in the "Project / Properties" dialog box, select

-and the directory where MinGW's GCC libs are installed
-(i.e. @file{C:\mingw\lib\gcc\mingw32\4.2.1-sjlj}). Then select
-"Linker / Input" from the tree view, and add the files @file{libavformat.a},
-@file{libavcodec.a}, @file{libavutil.a}, @file{libmingwex.a},
-@file{libgcc.a}, and any other libraries you used (i.e. @file{libz.a})

-
-@end enumerate
-
-@subsection Using shared libraries
-
-This is how to create DLL and LIB files that are compatible with MSVC++:
-
-@enumerate
-
-@item Add a call to @file{vcvars32.bat} (which sets up the environment
-variables for the Visual C++ tools) as the first line of @file{msys.bat}.
-The standard location for @file{vcvars32.bat} is
-@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
-and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
-If this corresponds to your setup, add the following line as the first line
-of @file{msys.bat}:
+Finally, run:

@example
-call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
-@end example
-
-Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
-and run @file{c:\msys\1.0\msys.bat} from there.
-
-@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
-from @file{Microsoft (R) Library Manager}, this means your environment
-variables are set up correctly, the @file{Microsoft (R) Library Manager}
-is on the path and will be used by FFmpeg to create
-MSVC++-compatible import libraries.
-
-@item Build FFmpeg with
-
-@example
-./configure --enable-shared
+./configure --toolchain=msvc
 make
 make install
@end example

-Your install path (@file{/usr/local/} by default) should now have the
-necessary DLL and LIB files under the @file{bin} directory.
+If you wish to compile shared libraries, add @code{--enable-shared} to your
+configure options. Note that due to the way MSVC handles DLL imports and
+exports, you cannot compile static and shared libraries at the same time, and
+enabling shared libraries will automatically disable the static ones.

+Notes:
+
+@itemize
+
+@item It is possible that coreutils' @code{link.exe} conflicts with MSVC's linker.
+You can find out by running @code{which link} to see which @code{link.exe} you
+are using. If it is located at @code{/bin/link.exe}, then you have the wrong one
+in your @code{PATH}. Either move or remove that copy, or make sure MSVC's
+@code{link.exe} takes precedence in your @code{PATH} over coreutils'.
+
+@item If you wish to build with zlib support, you will have to grab a compatible
+zlib binary from somewhere, with an MSVC import lib, or if you wish to link
+statically, you can follow the instructions below to build a compatible
+@code{zlib.lib} with MSVC. Regardless of which method you use, you must still
+follow step 3, or compilation will fail.
+@enumerate
+@item Grab the @uref{http://zlib.net/, zlib sources}.
+@item Edit @code{win32/Makefile.msc} so that it uses -MT instead of -MD, since
+this is how FFmpeg is built as well.
+@item Edit @code{zconf.h} and remove its inclusion of @code{unistd.h}. This gets
+erroneously included when building FFmpeg.
+@item Run @code{nmake -f win32/Makefile.msc}.
+@item Move @code{zlib.lib}, @code{zconf.h}, and @code{zlib.h} to somewhere MSVC
+can see.
@end enumerate

-Alternatively, build the libraries with a cross compiler, according to
-the instructions below in @ref{Cross compilation for Windows with Linux}.
+@item FFmpeg has been tested with Visual Studio 2010 and 2012, Pro and Express.
+Anything else is not officially supported.

-To use those files with MSVC++, do the same as you would do with
-the static libraries, as described above. But in Step 4,
-you should only need to add the directory where the LIB files are installed
-(i.e. @file{c:\msys\usr\local\bin}). This is not a typo, the LIB files are
-installed in the @file{bin} directory. And instead of adding the static
-libraries (@file{libxxx.a} files) you should add the MSVC import libraries
-(@file{avcodec.lib}, @file{avformat.lib}, and
-@file{avutil.lib}). Note that you should not use the GCC import
-libraries (@file{libxxx.dll.a} files), as these will give you undefined
-reference errors. There should be no need for @file{libmingwex.a},
-@file{libgcc.a}, and @file{wsock32.lib}, nor any other external library
-statically linked into the DLLs.
+@end itemize
+
+@subsection Linking to FFmpeg with Microsoft Visual C++
+
+If you plan to link with MSVC-built static libraries, you will need
+to make sure you have @code{Runtime Library} set to
+@code{Multi-threaded (/MT)} in your project's settings.

@chapter Syntax
@c man begin SYNTAX

-When evaluating specific formats, FFmpeg uses internal library parsing
-functions, shared by the tools. This section documents the syntax of
-some of these formats.
+This section documents the syntax and formats employed by the FFmpeg
+libraries and tools.
+
+@anchor{quoting_and_escaping}
+@section Quoting and escaping
+
+FFmpeg adopts the following quoting and escaping mechanism, unless
+explicitly specified. The following rules are applied:
+
+@itemize
+@item
+@code{'} and @code{\} are special characters (respectively used for
+quoting and escaping). In addition to them, there might be other
+special characters depending on the specific syntax where the escaping
+and quoting are employed.
+
+@item
+A special character is escaped by prefixing it with a '\'.
+
+@item
+All characters enclosed between '' are included literally in the
+parsed string. The quote character @code{'} itself cannot be quoted,
+so you may need to close the quote and escape it.
+
+@item
+Leading and trailing whitespaces, unless escaped or quoted, are
+removed from the parsed string.
+@end itemize
+
+Note that you may need to add a second level of escaping when using
+the command line or a script, which depends on the syntax of the
+adopted shell language.
+
+The function @code{av_get_token} defined in
+@file{libavutil/avstring.h} can be used to parse a token quoted or
+escaped according to the rules defined above.
+
+The tool @file{tools/ffescape} in the FFmpeg source tree can be used
+to automatically quote or escape a string in a script.
+
+@subsection Examples
+
+@itemize
+@item
+Escape the string @code{Crime d'Amour} containing the @code{'} special
+character:
+@example
+Crime d\'Amour
+@end example
+
+@item
+The string above contains a quote, so the @code{'} needs to be escaped
+when quoting it:
+@example
+'Crime d'\''Amour'
+@end example
+
+@item
+Include leading or trailing whitespaces using quoting:
+@example
+'  this string starts and ends with whitespaces  '
+@end example
+
+@item
+Escaping and quoting can be mixed together:
+@example
+' The string '\'string\'' is a string '
+@end example
+
+@item
+To include a literal @code{\} you can use either escaping or quoting:
+@example
+'c:\foo' can be written as c:\\foo
+@end example
