You didn't reply to my questions, neither did you explain your plans.
There are three - or actually just two relevant - subtitle formats
for internal handling:
- AVSubtitleType.SUBTITLE_BITMAP
- AVSubtitleType.SUBTITLE_ASS
with regards to subtitles, there's no need for negotiation: It's
either one or the other and as these are fundamentally different,
there's also no auto-conversion that needs to be handled.
Either a filter (or encoder) supports it or it doesn't.
Your proposals and plans might make sense for audio and video
formats, but I don't see how this would affect subtitle filtering.
If you want to REJECT my submission, please be SPECIFIC instead
of responding with your usual set of personal insults.
