Nvidia chromium with VP9 hardware decode?


Im trying for a few days to get my stadia on linux to work. But everything i do i cannot get vp9 hardware decoding.

I have already made a issue here: chromium for debian · Issue #64 · saiarcot895/chromium-ubuntu-build · GitHub

But maybe someone here have the answer.

I have a debian installation with nvidia version:

With version 440 we have support off VP9

<i>Added VP9 decode support to the NVIDIA VDPAU driver. See the VDPAU Support appendix in the README for supported VP9 decoder profiles.</i>

Here some extra information:

But when i run vainfo i don’t see any vp9 support :/

Can someone help me with this problem ?
