Sorry for the delay, I seem to have missed the report.

If the video card has been misdetected, it would be a bug in libvdpau1... I
think. Can you please run "glxinfo | grep OpenGL"?

I think you are confusing VA-API and VDPAU here. They are two different things,
and xvba-va-driver only provides a backend for VA-API.

Incidentally mpv suports VA-API as well, so you may want to try to enable it
using "-vo=opengl" (or "-vo=opengl-hq") and "-hwdec=vaapi", or directly using
the vaapi vo ("-vo=vaapi") and "-hwdec=vaapi" (but the opengl one should be
better).

Yeah, but it's kinda convoluted (VDPAU frontend that uses VAAPI frontend that
uses XvBA hardware... assuming thet it actually uses the xvba-va driver instead
of just falling back to opengl). Using VAAPI/XvBA directly should be better (if
anything it's one package less to have installed).

If you do want to use vdpau instead of vaapi/xvba, and it is supported by your
video card, you need a working vdpau driver (which, AFAICT, is not available in
Debian for fglrx).

Cheers
