Yesterday and today I have become aware of lipsync drift during
continuous playback. Restarting and stepping forward to the same point
restores good playback.
This is using 'Normal' decoding, shown on the later page as ffmpeg &
opengl or 'Standard', HQ Deinterlacers with no options ticked.
Current build b8e27f103, first suspected in ca1453f5, for el7
Seen both with and without AVSync2
DVB-T recordings. They have been processed using Project-X, which may
insert extra audio frames to maintain sync, but I've been using that for
years. I suppose the most obvious suspect is ca1453f, but I'm not sure
that it's active with my settings.
