Problem with mpv playback(VDPAU)

Hello everyone, I've been trying to get mpv with hardware acceleration(and some shaders) to work.

When trying to play any video I get the following output:

 Title: PSArips.com | Westworld.S02E10.The.Passenger.720p.10bit.WEBRip.2CH.x265.HEVC-PSA

Audio/Video desynchronisation detected! Possible reasons include too slow
hardware, temporary CPU spikes, broken drivers, and broken files. Audio
position will not match to the video (see A-V status field).

The output of vdpauinfo is:

display: :0   screen: 0
Error creating VDPAU device: 1

I've tried setting the environment variable

VDPAU_DRIVER=nvidia

like the wiki says which changed nothing.

The output of ls /usr/lib/vdpau :

libvdpau_nvidia.so  libvdpau_nvidia.so.1  libvdpau_nvidia.so.455.23.04  libvdpau_trace.so  libvdpau_trace.so.1  libvdpau_trace.so.1.0.0

Re: Problem with mpv playback(VDPAU)

Does other acceleration work properly? This error chain reads like a lot more is broken rather than just vdpau.

All of this points to a deeper issue than just vdpau being broken, post your xorg log and

glxinfo -B #mesa-demos
nvidia-smi
dmesg
