[mythtv-users] VAAPI support on newer Intel iGPUs

[Adam Stylinski]

I recently upgraded my frontend hardware but for whatever reason, vaapi support does not seem to be working.
It works just fine from mpv (though it _wants_ to use x11vk as the output, I can force it to be vaapi and it works
by using an env var that forces libva to not use DRI3).

I'm using the modesetting DDX if that's at all relevant, and the GPU is on a Raptor Lake CPU.  The verbose output
for playback tells me:
