Comment (by jim_32766@…):

 I too can confirm that vaapi and ffmpeg are alternating as I change
 channels. I have also noticed when first entering a channel, even though
 vaapi is selected, the frames decoded/free runs a very low ratio, e.g.
 4/19, and the playback is not smooth. A short pause, just a second, before
 resuming play results in a much higher ratio, e.g. 21/2, and the playback
 is smooth. I don't know if this is related but wanted to pass the
 information along.
