I continued to look into this. I found no pattern as to which -vf -vo
or -ao settings affect it. However, it seems to be related to frame
dropping. When it is slow enough (as happens with vo=vdpau:deint=4 on
my test system) to drop frames, with any frame-dropping setting, this
problem seems to surface. Perhaps it is not properly dropping frames?
I hope that helps someone realize what's going on. If not, I will
continue to try to track it down in the code myself.
