 without re-encoding.

 When you specify `-c copy`, you tell ffmpeg to copy the input file
 streams. It's therefore not ffmpeg's fault if those streams are not
 applicable for the output file.

 This bug relates to what would happen if you did `-c:v copy -c:a copy`,
 having ffmpeg figure out how to convert the subtitle stream.
