what does vainfo show?  You may need to install it.   You are looking
for something like below, I believe the main10 is what is needed for
your video.

     VAProfileHEVCMain               : VAEntrypointVLD
     VAProfileHEVCMain10             : VAEntrypointVLD

You may need to then confirm that your given video card supports those decoders.

Thanks so much for your help. This all worked properly before I upgraded to fc38 some time ago.

$ vainfo The.Equalizer.mkv

      VAProfileNone                   : VAEntrypointVideoProc

Thanks,
