@chapter Stream selection
@c man begin STREAM SELECTION

-@command{ffmpeg} provides the @code{-map} option for manual control of stream selection in each
-output file. Users can skip @code{-map} and let ffmpeg perform automatic stream selection as
-described below. The @code{-vn / -an / -sn / -dn} options can be used to skip inclusion of
-video, audio, subtitle and data streams respectively, whether manually mapped or automatically
-selected, except for those streams which are outputs of complex filtergraphs.
+By default, @command{ffmpeg} includes only one stream of each type (video, audio, subtitle)
+present in the input files and adds them to each output file.  It picks the
+"best" of each based upon the following criteria: for video, it is the stream
+with the highest resolution, for audio, it is the stream with the most channels, for
+subtitles, it is the first subtitle stream. In the case where several streams of
+the same type rate equally, the stream with the lowest index is chosen.

-@section Description
-The sub-sections that follow describe the various rules that are involved in stream selection.
-The examples that follow next show how these rules are applied in practice.
-
-While every effort is made to accurately reflect the behavior of the program, FFmpeg is under
-continuous development and the code may have changed since the time of this writing.
-
-@subsection Automatic stream selection
-
-In the absence of any map options for a particular output file, ffmpeg inspects the output
-format to check which type of streams can be included in it, viz. video, audio and/or
-subtitles. For each acceptable stream type, ffmpeg will pick one stream, when available,
-from among all the inputs.
-
-It will select that stream based upon the following criteria:
-@itemize
-@item
-for video, it is the stream with the highest resolution,
-@item
-for audio, it is the stream with the most channels,
-@item
-for subtitles, it is the first subtitle stream found but there's a caveat.
-The output format's default subtitle encoder can be either text-based or image-based,
-and only a subtitle stream of the same type will be chosen.
-@end itemize
-
-In the case where several streams of the same type rate equally, the stream with the lowest
-index is chosen.
-
-Data or attachment streams are not automatically selected and can only be included
-using @code{-map}.
-@subsection Manual stream selection
-
-When @code{-map} is used, only user-mapped streams are included in that output file,
-with one possible exception for filtergraph outputs described below.
-
-@subsection Complex filtergraphs
-
-If there are any complex filtergraph output streams with unlabeled pads, they will be added
-to the first output file. This will lead to a fatal error if the stream type is not supported
-by the output format. In the absence of the map option, the inclusion of these streams leads
-to the automatic stream selection of their types being skipped. If map options are present,
-these filtergraph streams are included in addition to the mapped streams.
-
-Complex filtergraph output streams with labeled pads must be mapped once and exactly once.
-
-@subsection Stream handling
-
-Stream handling is independent of stream selection, with an exception for subtitles described
-below. Stream handling is set via the @code{-codec} option addressed to streams within a
-specific @emph{output} file. In particular, codec options are applied by ffmpeg after the
-stream selection process and thus do not influence the latter. If no @code{-codec} option is
-specified for a stream type, ffmpeg will select the default encoder registered by the output
-file muxer.
-
-An exception exists for subtitles. If a subtitle encoder is specified for an output file, the
-first subtitle stream found of any type, text or image, will be included. ffmpeg does not validate
-if the specified encoder can convert the selected stream or if the converted stream is acceptable
-within the output format. This applies generally as well: when the user sets an encoder manually,
-the stream selection process cannot check if the encoded stream can be muxed into the output file.
-If it cannot, ffmpeg will abort and @emph{all} output files will fail to be processed.
-
-@section Examples
-
-The following examples illustrate the behavior, quirks and limitations of ffmpeg's stream
-selection methods.
-
-They assume the following three input files.
-
-@verbatim
-
-input file 'A.avi'
-      stream 0: video 640x360
-      stream 1: audio 2 channels
-
-input file 'B.mp4'
-      stream 0: video 1920x1080
-      stream 1: audio 2 channels
-      stream 2: subtitles (text)
-      stream 3: audio 5.1 channels
-      stream 4: subtitles (text)
-
-input file 'C.mkv'
-      stream 0: video 1280x720
-      stream 1: audio 2 channels
-      stream 2: subtitles (image)
-@end verbatim
-
-@subsubheading Example: automatic stream selection
-@example
-ffmpeg -i A.avi -i B.mp4 out1.mkv out2.wav -map 1:a -c:a copy out3.mov
-@end example
-There are three output files specified, and for the first two, no @code{-map} options
-are set, so ffmpeg will select streams for these two files automatically.
-
-@file{out1.mkv} is a Matroska container file and accepts video, audio and subtitle streams,
-so ffmpeg will try to select one of each type.@*
-For video, it will select @code{stream 0} from @file{B.mp4}, which has the highest
-resolution among all the input video streams.@*
-For audio, it will select @code{stream 3} from @file{B.mp4}, since it has the greatest
-number of channels.@*
-For subtitles, it will select @code{stream 2} from @file{B.mp4}, which is the first subtitle
-stream from among @file{A.avi} and @file{B.mp4}.
-
-@file{out2.wav} accepts only audio streams, so only @code{stream 3} from @file{B.mp4} is
-selected.
-
-For @file{out3.mov}, since a @code{-map} option is set, no automatic stream selection will
-occur. The @code{-map 1:a} option will select all audio streams from the second input
-@file{B.mp4}. No other streams will be included in this output file.
-
-For the first two outputs, all included streams will be transcoded. The encoders chosen will
-be the default ones registered by each output format, which may not match the codec of the
-selected input streams.
-
-For the third output, codec option for audio streams has been set
-to @code{copy}, so no decoding-filtering-encoding operations will occur, or @emph{can} occur.
-Packets of selected streams shall be conveyed from the input file and muxed within the output
-file.
-
-@subsubheading Example: automatic subtitles selection
-@example
-ffmpeg -i C.mkv out1.mkv -c:s dvdsub -an out2.mkv
-@end example
-Although @file{out1.mkv} is a Matroska container file which accepts subtitle streams, only a
-video and audio stream shall be selected. The subtitle stream of @file{C.mkv} is image-based
-and the default subtitle encoder of the Matroska muxer is text-based, so a transcode operation
-for the subtitles is expected to fail and hence the stream isn't selected. However, in
-@file{out2.mkv}, a subtitle encoder is specified in the command and so, the subtitle stream is
-selected, in addition to the video stream. The presence of @code{-an} disables audio stream
-selection for @file{out2.mkv}.
-
-@subsubheading Example: unlabeled filtergraph outputs
-@example
-ffmpeg -i A.avi -i C.mkv -i B.mp4 -filter_complex "overlay" out1.mp4 out2.srt
-@end example
-A filtergraph is setup here using the @code{-filter_complex} option and consists of a single
-video filter. The @code{overlay} filter requires exactly two video inputs, but none are
-specified, so the first two available video streams are used, those of @file{A.avi} and
-@file{C.mkv}. The output pad of the filter has no label and so is sent to the first output file
-@file{out1.mp4}. Due to this, automatic selection of the video stream is skipped, which would
-have selected the stream in @file{B.mp4}. The audio stream with most channels viz. @code{stream 3}
-in @file{B.mp4}, is chosen automatically. No subtitle stream is chosen however, since the MP4
-format has no default subtitle encoder registered, and the user hasn't specified a subtitle encoder.
-
-The 2nd output file, @file{out2.srt}, only accepts text-based subtitle streams. So, even though
-the first subtitle stream available belongs to @file{C.mkv}, it is image-based and hence skipped.
-The selected stream, @code{stream 2} in @file{B.mp4}, is the first text-based subtitle stream.
-
-@subsubheading Example: labeled filtergraph outputs
-@example
-ffmpeg -i A.avi -i B.mp4 -i C.mkv -filter_complex "[1:v]hue=s=0[outv];overlay;aresample" \
-       -map '[outv]' -an        out1.mp4 \
-                                out2.mkv \
-       -map '[outv]' -map 1:a:0 out3.mkv
-@end example
-
-The above command will fail, as the output pad labelled @code{[outv]} has been mapped twice.
-None of the output files shall be processed.
-
-@example
-ffmpeg -i A.avi -i B.mp4 -i C.mkv -filter_complex "[1:v]hue=s=0[outv];overlay;aresample" \
-       -an        out1.mp4 \
-                  out2.mkv \
-       -map 1:a:0 out3.mkv
-@end example
-
-This command above will also fail as the hue filter output has a label, @code{[outv]},
-and hasn't been mapped anywhere.
-
-The command should be modified as follows,
-@example
-ffmpeg -i A.avi -i B.mp4 -i C.mkv -filter_complex "[1:v]hue=s=0,split=2[outv1][outv2];overlay;aresample" \
-        -map '[outv1]' -an        out1.mp4 \
-                                  out2.mkv \
-        -map '[outv2]' -map 1:a:0 out3.mkv

-this message may span across multiple UDP packets and the only size
-limitation is that it shall fit as a whole in the sending buffer. The
