So I looked into libvdpau code and the problem here is just that libvdpau can't
find a proper VDPAU driver, so it defaults to "nvidia". It's not really a
problem here, since you don't have a vdpau driver installed anyway (that is,
unless you use libvdpau-va-gl1, but in that case you have to manually set
VDPAU_DRIVER anyway).

The error you see from mpv is harmless, since it falls back automatically to
using the opengl vo if vdpau doesn't work. But if it bothers you, you can
silence it by defaulting to opengl manually (e.g. via the command-line or in the
configuration file)... or by using libvdpau-va-gl1.

Yeah, I think so. It depends on how the video was encoded though, so other files
may work fine (the h264 "high" profile is used for HD movies and such).

fglrx and *vdpau* :) The problem is just that there is no VDPAU driver for fglrx
(even one that uses XvBA as backend like xvba-va-driver), unless you go the
libvdpau-va-gl1 -> xvba-va-driver route (the open-source Mesa Gallium3D drivers
do include vdpau drivers, but they don't seem to be built in Debian).

So um, overall I don't think there's really a bug in mpv here, so I'm closing
this report. Feel free to ask if you have any doubt, or reopen the report if you
think there's something to be fixed in mpv.

Cheers
