-Virtual concatenation script demuxer.
-
-This demuxer reads a list of files and other directives from a text file and

-
-The timestamps in the files are adjusted so that the first file starts at 0

-Both following use cases rely on pkg-config and make, thus make sure
-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.

-@c man begin FORMAT OPTIONS
-
-The libavformat library provides some generic global options, which
-can be set on all the muxers and demuxers. In addition each muxer or
-demuxer may support so-called private options, which are specific for
-that component.
-
-Options may be set by specifying -@var{option} @var{value} in the
-FFmpeg tools, or by setting the value explicitly in the

-
-@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 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}.
-
-@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 center mix level. It is a value expressed in deciBel, and must be
-inclusively included between -32 and +32.
-
-@item slev, surround_mix_level
-Set surround mix level. It is a value expressed in deciBel, and must
-be inclusively included between -32 and +32.
-
-@item lfe_mix_evel
-Set LFE mix level.
-
-@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
-@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
-@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, must be included
-between 0 and 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 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 included between
-2 and 16, default value is 9.

-The libswresample library performs highly optimized audio resampling,
-rematrixing and sample format conversion operations.
-
-Specifically, this library performs the following conversions:
-
-@itemize
-@item
-@emph{Resampling}: is the process of changing the audio rate, for
-example from an high sample rate of 44100Hz to 8000Hz. Audio
-conversion from high to low sample rate is a lossy process. Several
-resampling options and algorithms are available.
-
-@item
-@emph{Format conversion}: is the process of converting the type of
-samples, for example from 16-bit signed samples to unsigned 8-bit or
-float samples. It also handles packing conversion, when passing from
-packed layout (all samples belonging to distinct channels interleaved
-in the same buffer), to planar layout (all samples belonging to the
-same channel stored in a dedicated buffer or "plane").
-
-@item
-@emph{Rematrixing}: is the process of changing the channel layout, for
-example from stereo to mono. When the input channels cannot be mapped
-to the output streams, the process is lossy, since it involves
-different gain factors and mixing.
-@end itemize
-
-Various other audio conversions (e.g. stretching and padding) are
-enabled through dedicated options.

-The third byte represents the width and height chroma subsampling

-Finally, run:
+@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

+@subsection Using shared libraries

+variables for the Visual C++ tools) as the first line of @file{msys.bat}.
+The standard location for @file{vcvars32.bat} is
+@file{C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat},
+and the standard location for @file{msys.bat} is @file{C:\msys\1.0\msys.bat}.
+If this corresponds to your setup, add the following line as the first line
+of @file{msys.bat}:
 
 @example
-./configure --toolchain=msvc
+call "C:\Program Files\Microsoft Visual Studio 8\VC\bin\vcvars32.bat"
+@end example
+
+Alternatively, you may start the @file{Visual Studio 2005 Command Prompt},
+and run @file{c:\msys\1.0\msys.bat} from there.
+
+@item Within the MSYS shell, run @code{lib.exe}. If you get a help message
+from @file{Microsoft (R) Library Manager}, this means your environment
+variables are set up correctly, the @file{Microsoft (R) Library Manager}
+is on the path and will be used by FFmpeg to create
+MSVC++-compatible import libraries.
+
+@item Build FFmpeg with
+
+@example
+./configure --enable-shared
 make
 make install
 @end example
 
-If you wish to compile shared libraries, add @code{--enable-shared} to your
+Your install path (@file{/usr/local/} by default) should now have the
-configure options. Note that due to the way MSVC handles DLL imports and
+necessary DLL and LIB files under the @file{bin} directory.
-exports, you cannot compile static and shared libraries at the same time, and
-enabling shared libraries will automatically disable the static ones.
 
-Notes:
-
-@itemize

-
+some of these formats.
-@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
