On this page
https://www.mythtv.org/wiki/Release_Notes_-_31_Video_decoding_and_playback
they state "The full list of supported hardware codecs available for a
system is now shown in the 'System status' page ('Video decoders' tab)
in the Mythfrontend GUI". It was when I visited that screen (which was
empty!!) that I got this error in the console where I started
mythfrontend: "Failed to initialise VAAPI connection: -1 (unknown libva
error)" when "Trying to open /usr/lib64/dri/i965_drv_video.so".
Turns out I needed to install the libva-intel-driver package. A
re-visit to the playback profiles settings gave me much more to choose
from and now playback is normal. Phew...
