Comment (by gjdfgh):
OK, found out that libass provides a separate function ass_process_data(),
which can takes "complete" ASS events as libavformat outputs them. While
it's a bit annoying that you can't get the length of the subtitle event in
the AVPacket duration/convergence_duration fields, these are not really
needed when using libass (or if you need them, use the libavcodec ass
decoder).
You actually can't get the Matroska ReadOrder field, which is used yb
libass for something. I don't know if this is a bug or a caveat, or if
it's actually handled in some way.
Can't close this myself as invalid. Sorry for the noise.
