 As a general rule, options are applied to the next specified
 file. Therefore, order is important, and you can have the same
 option on the command line multiple times. Each occurrence is
 then applied to the next input or output file.

+@section Stream specifiers
+Some options are applied per-stream, e.g. bitrate or codec. Stream specifiers
+are used to precisely specify which stream(s) does a given option belong to.
+
+A stream specifier is a string generally appended to the option name and
+separated from it by a colon. E.g. @code{-codec:a:1 ac3} option contains
+@code{a:1} stream specifer, which matches the second audio stream. Therefore it
+would select the ac3 codec for the second audio stream.
+
+A stream specifier can match several stream, the option is then applied to all
+of them. E.g. the stream specifier in @code{-b:a 128k} matches all audio
+streams.
+
+An empty stream specifier matches all streams, for example @code{-codec copy}
+or @code{-codec: copy} would copy all the streams without reencoding.
+
+Possible forms of stream specifiers are:
+@table @option
+@item @var{stream_index}

+thread count for the second stream to 4.

-You can precisely specify which stream(s) should the codec AVOption apply to by
-appending a stream specifier of the form
-@option{[:@var{stream_type}][:@var{stream_index}]} to the option name.
-@var{stream_type} is 'v' for video, 'a' for audio and 's' for subtitle streams.
-@var{stream_index} is a global stream index when @var{stream_type} isn't
-given, otherwise it counts streams of the given type only. As always, the index
-is zero-based. For example
-@example
--foo -- applies to all applicable streams
--foo:v -- applies to all video streams
--foo:a:2 -- applies to the third audio stream
--foo:0 -- applies to the first stream
-@end example
+All codec AVOptions are obviously per-stream, so the chapter on stream
+specifiers applies to them
