I have an NVIDIA GPU from the GeForce 16 series (Turing). How do I enable hardware video acceleration in Firefox?
Typically I’d install the proprietary/semiopen NVIDIA driver and nvidia-vaapi-driver, but I couldn’t find the nvidia-vaapi-driver package for openSUSE Tumbleweed.
What do you see in about:support in section Graphics.
For me hardware acceleration has been blocked (since FF137), because my video card is too old.
env blocklisted Blocklisted by gfxInfo Blockiert; Fehlercode FEATURE_HARDWARE_VIDEO_DECODING_NO_R600
I forced it with media.hardware-video-decoding.force-enabled set to true in about:config
You can also search https://searchfox.org/mozilla-release/source/widget/gtk/GfxInfo.cpp for some hints.
For me it says “Blocklisted; failure code FEATURE_FAILURE_VIDEO_DECODING_TEST_FAILED”, even with media.hardware-video-decoding.force-enabled enabled. Should I have a VA-API driver in place? Here’s vainfo:
Trying display: wayland
libva info: VA-API version 1.22.0
libva info: Trying to open /usr/lib64/dri/nvidia_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit
I see that the source code you link to also references support for v4l2 (Video4Linux?). Should I install something for that?
Sorry, I can’t help with Nvidia. Never used it and most likely never will.
Found it: if I manually compile GitHub - elFarto/nvidia-vaapi-driver: A VA-API implemention using NVIDIA's NVDEC (which doesn’t seem to be in openSUSE’s official repos) it works.
The Tumbleweed package is marked as experimental, so for now I’ll stick with the version I compiled straight from the original author.
