Do you actually need that, except for the merge part?

Also, note that currently, the text subtitles packets do not include the
terminating NUL character, while your ff_subtitles_queue_read_packet
includes it.

I think it should be in AVStream.time_base. But this API does not need to
know about it, it only uses it to sort and compute the missing duration

I do not see what makes them only work for strings.
