Description

After upgrading from 0.24 to 0.27 fixes there is problem with dvb-t subtitles. When I change channel which contains subtitles, they not allways show up. I must manually turn them on from playback menu. I have set "allways show subtitles" in settings.

I've seen this problem for a while, but on playback of already-recorded programs. Specifically, when starting playback, captions may not display until manually selected.

I suspect this is related to some relatively recent improvements in buffering and playback startup latency. With a smaller buffer, it's more likely that subtitle info isn't found until after playback actually starts. When it is eventually encountered, it's added to the OSD playback menu but the default decision has already been made.

I think the way to approach this to auto-upgrade to a "better" subtitle track whenever new tracks are discovered, unless the user has explicitly chosen some track.

This should be fixed in 0.27-fixes as of bcf888fdd4034997c2f2a5d0d877da0e1f463c2e (but I don't have a good way of testing it).

Please test and reopen if you still see the problem.

Need to reopen this. Maybe subtitle detection seems a little better, but still no subs after change channels few times.

Probably the following commits need to be backported:

I'll do that after everything settles in master.

Could you update to the latest fixes-0.27 (7962008be23de99d3bd69e1603d69749f4678a3c at this writing) and report back whether you still see any problems?
