 // NOTE: this is a partial update of the Avisynth C interface to recognize
 // new color spaces added in Avisynth 2.60. By no means is this document
 // completely Avisynth 2.60 compliant.
-// 170103: added new CPU constants (FMA4, AVX512xx)
-// 171102: define SIZETMOD. do not use yet, experimental. Offsets are size_t instead of int. Affects x64.
-// 171106: avs_get_row_size calls into avs_get_row_size_p, instead of direct field access
-// 171106: avs_get_height calls into avs_get_row_size_p, instead of direct field access
-// 180524: AVSC_EXPORT to dllexport in capi.h for avisynth_c_plugin_init
-// 180524: avs_is_same_colorspace VideoInfo parameters to const
-// 181230: Readability: functions regrouped to mix less AVSC_API and AVSC_INLINE, put together Avisynth+ specific stuff
-// 181230: use #ifndef AVSC_NO_DECLSPEC for AVSC_INLINE functions which are calling API functions
-// 181230: comments on avs_load_library (helper for loading API entries dynamically into a struct using AVSC_NO_DECLSPEC define)
-// 181230: define alias AVS_FRAME_ALIGN as FRAME_ALIGN
-// 181230: remove unused form of avs_get_rowsize and avs_get_height (kept earlier for reference)
-// 190104: avs_load_library: smart fallback mechanism for Avisynth+ specific functions:
-//         if they are not loadable, they will work in a classic Avisynth compatible mode
-//         Example#1: e.g. avs_is_444 will call the existing avs_is_yv24 instead
-//         Example#2: avs_bits_per_component will return 8 for all colorspaces (Classic Avisynth supports only 8 bits/pixel)
-//         Thus the Avisynth+ specific API functions are safely callable even when connected to classic Avisynth DLL

-
-@subsection Options
-
-The wrapper supports the following standard libavcodec options:
-
-@table @option
-
-@item b
-Set bitrate target in bits/second.  By default this will use
-variable-bitrate mode.  If @option{maxrate} and @option{minrate} are
-also set to the same value then it will use constant-bitrate mode,
-otherwise if @option{crf} is set as well then it will use
-constrained-quality mode.
-
-@item g keyint_min
-Set key frame placement.  The GOP size sets the maximum distance between
-key frames; if zero the output stream will be intra-only.  The minimum
-distance is ignored unless it is the same as the GOP size, in which case
-key frames will always appear at a fixed interval.  Not set by default,
-so without this option the library has completely free choice about
-where to place key frames.
-
-@item qmin qmax
-Set minimum/maximum quantisation values.  Valid range is from 0 to 63
-(warning: this does not match the quantiser values actually used by AV1
- divide by four to map real quantiser values to this range).  Defaults
-to min/max (no constraint).
-
-@item minrate maxrate bufsize rc_init_occupancy
-Set rate control buffering parameters.  Not used if not set - defaults
-to unconstrained variable bitrate.
-
-@item threads
-Set the number of threads to use while encoding.  This may require the
-@option{tiles} or @option{row-mt} options to also be set to actually
-use the specified number of threads fully. Defaults to the number of
-hardware threads supported by the host machine.
-
-@item profile
-Set the encoding profile.  Defaults to using the profile which matches
-the bit depth and chroma subsampling of the input.
-
-@end table
-
-The wrapper also has some specific options:
-
-@table @option
-
-@item cpu-used
-Set the quality/encoding speed tradeoff.  Valid range is from 0 to 8,
-higher numbers indicating greater speed and lower quality.  The default
-value is 1, which will be slow and high quality.
-
-@item auto-alt-ref

-default of the library.
-

-
-@item crf
-Set the quality/size tradeoff for constant-quality (no bitrate target)
-and constrained-quality (with maximum bitrate target) modes. Valid
-range is 0 to 63, higher numbers indicating lower quality and smaller
-output size.  Only used if set; by default only the bitrate target is
-used.
-
-@item static-thresh
-Set a change threshold on blocks below which they will be skipped by
-the encoder.  Defined in arbitrary units as a nonnegative integer,
-defaulting to zero (no blocks are skipped).
-
-@item drop-threshold
-Set a threshold for dropping frames when close to rate control bounds.
-Defined as a percentage of the target buffer - when the rate control
-buffer falls below this percentage, frames will be dropped until it
-has refilled above the threshold.  Defaults to zero (no frames are
-dropped).

@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

-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
-@end example
-The video stream from @file{B.mp4} is sent to the hue filter, whose output is cloned once using
-the split filter, and both outputs labelled. Then a copy each is mapped to the first and third
-output files.
-
-The overlay filter, requiring two video inputs, uses the first two unused video streams. Those
-are the streams from @file{A.avi} and @file{C.mkv}. The overlay output isn't labelled, so it is
-sent to the first output file @file{out1.mp4}, regardless of the presence of the @code{-map} option.
-
-The aresample filter is sent the first unused audio stream, that of @file{A.avi}. Since this filter
-output is also unlabelled, it too is mapped to the first output file. The presence of @code{-an}
-only suppresses automatic or manual stream selection of audio streams, not outputs sent from
-filtergraphs. Both these mapped streams shall be ordered before the mapped stream in @file{out1.mp4}.
-
-The video, audio and subtitle streams mapped to @code{out2.mkv} are entirely determined by
-automatic stream selection.
-
-@file{out3.mkv} consists of the cloned video output from the hue filter and the first audio
-stream from @file{B.mp4}.
