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.
