Comment (by Stuart Auchterlonie):

 Testing results:

 - f25 system, works with both vaapi and vaapi2, mpeg and h264 content
 - f28 system (the one with wayland) doesn't initialize properly with
 `20180819_1258_vaapi_add_xvideo.patch`, however after applying

 }}}

 Then VAAPI successfully initializes. I can also playback MPEG2 and H264
 content, although I have 1 H264 recording which seems to wedge the
 decoder.
