VDPAU not working with nouveau

Max_UA · 2023-09-13 05:31:47

Hello, I am struggling to get VDPAU and VAAPI hardware video decode acceleration working with nouveau and NV50 hardware.

The hardware is a quadro NVS 160m in a dell Latitude e6400. This is NOT a dual GPU laptop, the nvidia GPU is the only GPU in the laptop.
According to https://www.techpowerup.com/gpu-specs/q … 160m.c1475 , This GPU has a PureVideo HD: VP3
The feature matrix at https://nouveau.freedesktop.org/VideoAcceleration.html, VDPAU should be supported for my GPU.
I have installed mesa-vdpau and nouveau-fw, which is all that (I think) should be needed for VDPAU to work.

I tested if hardware acceleration works using MPV with the --hwdec=auto flag, playing a 720p h264 video downloaded from youtube using yt-dlp.

The player window opens but is stuck on the first frame of the video, and I get EGL and CUDA errors:

I also get this nouveau error log in dmesg:

Not sure what commands would give adequate system info, but here is a neofetch:

In most cases, the system (other than the mouse) hangs, and I cannot switch to a tty, forcing me to hard shut down the laptop.
So, Am I doing something wrong, is my hardware at fault, or is nouveau support for VDPAU flaky enough to cause issues like these?
This is my first post, so If you need any additional info about my device please ask!

Probably both of the latter. That hardware isn't good, wasn't good when it was released and additionally - apparantly - third generation PureVideo cards have a HW defect/limitation not allowing to decode most H264 ranges: https://en.wikipedia.org/wiki/Nvidia_Pu … reVideo_HD http://download.nvidia.com/XFree86/Linu … dix-h.html
