Video passthrough doesn't seem to work

[Cqoicebordel]

I just updated to the 101 version (Chromium 101.0.4951.15 Ubuntu 20.04) and the video decoding seems broken.
In chrome:gpu it looks ok (Video Decode: Hardware accelerated) but videos are not accelerated (as shown in the devtools/media tab. I've double checked it, as I have looked at the usage of the GPU video HWA, which stayed at 0.
Just to note, the previous version worked, so I can really see the difference.

I've tried multiple things (like switching on Vulkan for a spell, switching flags here and there) but nothing seems to make it work.
I also tried to activate --use-gl=egl instead of desktop, but I got a black screen.

I'm attaching the GPU page, and the verbose output of chromium, running with chromium-browser --verbose --enable-features=VaapiVideoDecoder --enable-accelerated-video-decode 2> chromium.log (note that the log have been anonymised, I hope not too much or not much enough, but I have a clean copy, just in case)

chromium-gpu.log
chromium.log

This bug is a FYI more than a request for help. I gratefully appreciate any and all work you have done here thus far :)

Same here but on Intel GPU instead of Nvidia: Chromium 101, Ubuntu 20.04. It used to work with version 97.
The log shows this:

[65185:65185:0425/201003.500039:VERBOSE1:vaapi_wrapper.cc(939)] Unsupported value 2 for VAConfigAttribRateControl

when I play 1080@30 or 60 fps video on Youtube.

btw @Cqoicebordel you leak a few private emails in the log.

@vmarkovtsev thanks a lot. I didn't think to check for email addresses. Was stupid of me. I edited my post.

Follow up: I returned back VAAPI by specifying this cmdline argument: --disable-features=UseChromeOSDirectVideoDecoder

It didn't work for me. Still video decode shown as hardware accelerated in :gpu, still nothing done on GPU.
The fact that GpuMemoryBuffers Status shows all as Software only is not a good sign I think.
