 * This is identical to upstream
   https://code.mythtv.org/trac/ticket/12992

[Test Case]

 1. Set up mythtv
 2. Configure vdpau video decoder with de-interlacing
 3. On frontend select play on h265/hevc encoded media
 4. See error

[Regression Potential]

 * Fix is narrowly applied to hevc/h265 decoding in the vdpau decoder.
