Comment # 3 on bug 81444 from Harald Judt

I believe the playback issues may not be related to the -22 error. I've
downgraded ffmpeg from 2.3 to 2.2.5, and the choppiness and issues both with xv
and vdpau seem solved, so this was very likely a software problem (long-time
test still pending).

I will try to reproduce the -22 error in one or two weeks, using kdenlive with
mlt (with vdpau support) seemed to have been a certain way to make it happen
pretty fast.
