Klaas

The message is telling you that the VAAPI functionality check failed
and as a result you are using software playback.

Assuming you are using wayland, I'm fairly sure the issue is that you
don't have the vaapi drm package installed. FFmpeg these days uses a
DRM connection first and only then falls back to trying an X11
connection.

What does 'grep -in vaapi_drm *' show when run from your mythtv source
directory?

If VAAPI DRM is available, it should show something like:-

config.h:389:#define HAVE_VAAPI_DRM 1
config.mak:547:HAVE_VAAPI_DRM=yes

Likewise 'apt search libva-drm' should tell you what packages are installed.

thanks and regards
