Impossible to get HW DECODE despite good output of vaapi

[lukolszewski]

I have dual RTX3090 with driver 550.142 and vainfo returns this:

I've tried various things including pointing both firefox-nightly, chrome and latest thorium to specific gpu. Firefox specifically to a specific DRM device with MOZ_DRM_DEVICE. The furthest I got was firefox-nightly claiming HW Encode was fine, but never decode. The errors I seem to get are a variant of:

in chrome/thorium:

[2467688:2467688:0111/030802.822336:ERROR:ui/gl/gl_surface_egl.cc:357] No suitable EGL configs found for initialization.
Created TensorFlow Lite XNNPACK delegate for CPU.
Attempting to use a delegate that only supports static-sized tensors with a graph that has dynamic-sized tensors (tensor#-1 is a dynamic-sized tensor).
[2467642:2467669:0111/030805.752188:ERROR:google_apis/gcm/engine/registration_request.cc:291] Registration response error message: DEPRECATED_ENDPOINT

Firefox is not logging any errors, it just mentions the multi gpu setup.

Is this supposed to be working in direct mode with apps? (I have the env vars LIBVA_DRIVER_NAME=nvidia NVD_BACKEND=direct added)

Vainfo seems happy, but apps are not.

If anyone has gotten it working, please let me know how.

[mon]

Just to add that on a fresh Kubuntu install I'm having similar symptoms; where vainfo shows all good, but Firefox seems unhappy.

I've tried the Snap (default), .deb via PPA, Flatpak, and nightly via the ubuntu-mozilla-daily PPA to no effect. Have used 0.0.14 via apt as well as building it myself. mpv/ffmpeg seem to have no issues. If I get time I'll try and get good logs for why it fails, NVD_LOG=1 doesn't show anything useful in Firefox; and in vainfo it just shows successful loading of the driver.

5070 Ti + 3070 here on driver 590.48. Cannot get it working no matter what. I've probably spent hours on this.

[mon]

Update from my testing: Nightly works. I actually went all the way to building my own copy of Firefox and doing rr debugging on the graphics init pipeline before realising I forgot to enable media.hardware-video-decoding.force-enabled in the nightly user profile.

If I get the energy later, I'll do a git bisect and see if there's some specific commit that fixed it.

[ryanull24]

an update from me too. firefox stable 146 seems fine now. for some reason.
With a new profile in firefox, setting
gfx.webrender.layer-compositor = true
and
media.hardware-video-decoding.force-enabled = true

appears to be working. i see gpu usage / clocks going up when playing, for example, an av1 4320p video on youtube (here). in nvtop, decoder is shown as not being used (as opposed to say, simply using a video player like haruna), but that might be due to the multiple layers of how hw acceleration is used.

[ryanull24]

new update. tried getting it working on helium browser (chromium), since i am not totally satisfied with firefox.

I was able to get it almost working using:
" CUDA_VISIBLE_DEVICES=1 __NV_PRIME_RENDER_OFFLOAD=1 helium-browser --ozone-platform=wayland" and #ignore-gpu-blacklist enabled in chrome://flags (though i don't think this last flag has any effect though)
(I render the desktop on my 2nd gpu, which, strangely, nvidia-smi reports based on pci bus, gpu 0 is the 3070, gpu 1 is the 5070 Ti, but CUDA does it the other way around, device 0 is the 5070 Ti, device 1 is the 3070)

alternatively, this works too

export CUDA_VISIBLE_DEVICES="GPU-22f18bc9-67fb-8223-1a54-0ca2f62e1821" (this is the 3070)
export __NV_PRIME_RENDER_OFFLOAD=1

helium-browser --ozone-platform=wayland

I see NVDEC usage ~20% for a 4k av1 youtube video, nvidia-smi reports C+G

but then, ultimately it crashes in a few seconds.

GPU 1 (Primary): RTX 5070 Ti (x16 slot)

GPU 2 (Secondary): RTX 3070 (x4 slot) - This is the target for decoding.

Compositor: Wayland

Driver: NVIDIA 590.48.01 (Latest)
