Comment (by slhck):
> If it could autoselect the codec when using -map 0 -c:v copy -c:a copy
that would be great.
That's what it would do anyway.
If you do not specify `-map 0` it will only take the first subtitle stream
and re-encode it. (Or as currently implemented, not re-encode it, but
fail.)
> there are other subtitle streams of other types that I want to keep.
Then you need to specify `-c:s:1 copy` or whatever the stream index of the
subtitle stream you want copied is.
