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".
+configure option @code{--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 description of some of the currently available demuxers follows.
+@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".
+
+@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.).
+
+@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.

+@section rawvideo
-Apple HTTP Live Streaming demuxer.
+Raw video 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".
+This demuxer allows to read raw video data. Since there is no header
+specifying the assumed video parameters, the user must specify them
+in order to be able to decode the data correctly.
+
+This demuxer accepts the following options:
+@table @option
+
+@item framerate
+Set input video frame rate. Default value is 25.
+
+@item pixel_format
+Set the input video pixel format. Default value is @code{yuv420p}.
+
+@item video_size
+Set the input video size. This value must be specified explicitly.
+@end table
+
+For example to read a rawvideo file @file{input.raw} with
+@command{ffplay}, assuming a pixel format of @code{rgb24}, a video
+size of @code{320x240}, and a frame rate of 10 images per second, use
+the command:
+@example
+ffplay -f rawvideo -pixel_format rgb24 -video_size 320x240 -framerate 10 input.raw
