Comment (by Doug Larrick <doug@…>):
Duplicate, sure, but with patch.
I would say that realtime scheduling of the video sync thread is crucial
on a low-resource device such as Raspberry Pi. Certainly it helps
immensely in my testing --
as it did on the PC hardware of the day back in 2004 when I originally
implemented this feature. Showing the next frame at the correct time is a
real-time task, after all. On a modern PC there's enough spare CPU power
that it hardly matters. Unfortunately QThread does not seem to support
realtime scheduling.
