[FFmpeg-devel] [PATCH] matroskadec: set duration also for subtitles.

That is true, but the other solutions have drawbacks too.

1. allow demuxers to store either duration or convergence_duration;
2. check that all demuxers make a special case for subtitles and store
   convergence_duration;
3. in av_read_frame, copy duration into convergence_duration if necessary.

Solution 3 seems the less complex, but it is not very elegant.

By the way, I just noticed that NUT does not store any duration at all. What
should we do about it?
