Enforce vaapi even when a vdpau backend is available

Reported by: kwizart Owned by: Peter Bennett
Priority: minor Milestone: unknown
Component: MythTV - Video Playback Version: Unspecified
Severity: medium Keywords:
Cc: Ticket locked: no


On an Intel adapter where both a native vaapi backend and the libvdpau-va-gl api bridge are available. It should be possible to enforce vaapi even if it's possible to use a vdpau screen.

In my case the vdpau output is all green when using vdpau with mythfrontend.

As a side notes, using: 1/ auto ui with vaapi works..., but is delayed, sounds cracks 2/ qt ui with vaapi -> fails. 3/ qt ui with high res (xv) gives better results.

In the case 1/ the CPU load for the mythtv process seems to say the vaapi hw works as appropriate.

Note that you cannot use OpenGL with the QT theme painter. Because vaapi uses OpenGL you cannot use vaapi with QT theme painter.

I do not really understand the issue. If you have OpenGL theme painter and select VAAPI or VAAPI2 in the playback profile, what happens?

Also please let us know the version of MythTV.
