[Test Case]
1. Set up mythtv
2. Configure mythtv vdpau video decoder with de-interlacing
3. On frontend play h265/hevc encoded media, with nvidia-375+ and a pascal
or newer nvidia card.
4. See error
[Regression Potential]
* Fix is narrowly applied to hevc/h265 decoding in the vdpau decoder.
* Possible but unlikely regressions may be deinterlacing being broken, or
vdpau ceasing to function.
[Other Info]
* https://en.wikipedia.org/wiki/Nvidia_PureVideo . This will only affect
video cards that have hevc decoding which is VDPAU Feature set E,F,G,H.
