[mythtv-users] ffmpeg vs vdpau decode for h264

[Tom Dexter]

What would cause MythTV to use ffmpeg decoding as apposed to vdpau
when playing back h264 video? A followup question to that: Is there
any reason this would be happening more with version 30.0 than with
29.1? It cound be coincidence but I seem to be running into that more.
I know there were changes related to h265, but I'm not aware of
anything around h264.

Thanks!
Tom
