Thanks - that had the same problem here. I've pushed an update and it
should play without issue now; but note that while playback was
jittery for me, I couldn't 'encourage' it to crash at all...

That plays without issue here (VAAPI, VDPAU, NVDEC and MediaCodec
tested) - before and after the latest fix.

I'd like to push these NVDEC updates to the 31 branch if they are
stable - so if you see any more problems, please shout.

Is the issue with OpenGL/EGL etc resolved?
