[mythtv-users] Black screen when playing video, using Intel Graphics on KabyLake & VAAPI

[Andrew Theurer]

Wondering if anyone knows what to do here.  I have tried 0.28 and master
branch on git but get the same problem.  I have an Intel NUC with KabyLake,
and I have configured Myth to use OpenGL painter, with VAAPI playback
profile, and I have updated Intel i965 driver to the latest.  When I pick a
video or TV show to watch, I get a black screen, and it thinks it playing
the video.  I can "pause" and the UI showing the position in the video
comes up.  However, the rest of the screen is still black.

I tried VLC on the same system, and I can play videos no problem using the
Intel VAAPI.

Below is the log from mythfrontend.  I am not worried about the audio stuff
just yet.  Forgot to mention, I have also tried older versions of the intel
i965 driver, but still get the same black screen with Mythtv.  I am curious
what the "VAAPI: Error at vaapicontext.cpp:879 (#20, the requested function
is not implemented)" really means.

Thanks,

-Andrew
