 It would be great to see support for embedded ASS subtitles.
 Currently ASS subtitles are only supported if there is an external .ass
 file, but almost always it is a stream inside an MKV container (so there
 are 3 streams: video, audio and ASS subtitle)

 It is possible currently to extract the subtitle stream from the original
 container, then load it in a second step, but it would be cool to be able
 to do it in one step instead.

 For example in MEncoder you use:
 mencoder input.mkv -ass -o output.mkv
 And it will burn the ASS/SSA subtitles contained within input.mkv onto the
 video stream of output.mkv
