As far as I know, setting a disposition for a stream is only based on
stream specifier.
{{{
-disposition:s:0 default
}}}
For videos with streams of multiple languages, it would be great if we can
also set a disposition based on the language, regardless of its stream
specifier number.
{{{
-disposition:s:m:language:eng default
}}}
If there are multiple subtitles for the same language, and only want to
set one as default, forced, or any other output, an additional option will
be helpful too.
In this example, there are 3 Spanish subtitles, and want to set the 3rd
Spanish subtitle as the default, maybe something like?
{{{
-disposition:s:m:language:eng:2 default
}}}
(with 2 referring to Stream #0:4 (the 3rd Spanish subtitle stream))
{{{
Stream #0:0[0x1](und): Video: h264 (Constrained Baseline) (avc1 /
0x31637661), yuv420p(progressive), 626x360, 1231 kb/s, 26.20 fps, 26.17

}}}
----
Reason for request: I have hundreds of videos with multiple subtitles in
different languages, however a lot of them are default/forced in another
language and I want to set all of them to default in English WITHOUT
removing the other languages.
Thank you!
