Replying to [ticket:6304 slaanesh]:
> Summary of the bug: Different behaviours with subtitles in HandBrake
compiled with libav vs ffmpeg.
avconv contains several hundred known bugs that are not present in FFmpeg,
some of them subtitle-related. Handbrake contains work-arounds for many of
those bugs (the Handbrake developers know of these bugs but prefer to use
avconv, they are currently very active in fixing some of the bugs in
avconv). I suspect you have to remove some of the work-arounds to make
subtitle handling work correctly.

For this issue, I suspect you have to map AV_CODEC_ID_SUBRIP against
Handbrake's internal subtitle codec.
