This seems to be related to MP4 HEVC videos. My VAAPI can't do it (Intel 
Haswell), so Myth falls back to VDPAU even though VAAPI is selected as 
the profile. The VDPAU works fine on the first run but crashes on the 
next run.

CoreContext mythrender_vdpau.cpp:1796 (CheckHardwareSupport) VDPAU: 
Information OpenGL/VAAPI/libswscale
  backend for VDPAU

... which is from libvdpau-va-gl1, not the mesa package I mentioned before.

I removed libvdpau-va-gl1 and now it can't fall back to VDPAU, and it 
doesn't crash. Will need a bit of time to determine if the overall 
performance/quality is acceptable now though.
