Comment:

 VDPAU has been mostly re-written in master.

 Currently, interlaced HEVC material is a lottery - both with and without
 VDPAU.

 FFmpeg generally returns a single field (as in a half height frame), more
 often than not the content is not flagged as interlaced, the current
 NVIDIA drivers will hang if you try to deinterlace any HEVC that is
 actually progressive (this is a regression - they did not do this
 previously) and a lot of the HEVC samples are actually HEVC MAIN 10 -
 which VDPAU cannot decode anyway.

 But other than that, it's great:)

 Some samples do actually deinterlace correctly - but they are always half
 height. None of these issues are in the MythTV code.
