RTX 5070 Ti decoder doesn't work

Aurora
1

For the information, I use aurora-dx-nvidia-open:latest.
I tried playing videos on Haruna, it used software decoding (CPU).
I tried checking codec on Firefox about:support, it also showed no hardware decoding.
Meanwhile when I tried to record using OBS, I could encode on it no problem.

When I plugged my RTX 2000 Ada Generation (RTX 40 Series/Ada Lovelace equivalent), it worked properly.
If I boot to Windows, everything on the 5070 Ti (encoder/decoder) works properly.

I already updated flatpak to get the latest org.freedesktop.Platform.GL.nvidia and org.freedesktop.Platform.GL32.nvidia (570.133.07). Is there anything I can do? Or even get the log about the problem?

You did not say what format you were trying to decode. Firefox just recently added hardware decoding support in Linux for some more video formats. Not sure if hardware decode is enabled by default. Make sure you have the very latest Firefox release and hardware decode is enabled in settings.

For Haruna, did you try specifying the hardware decoding in settings? I have AMD GPU, and it works for me. Not sure if the open nVidia drivers have hardware decode or not. Try and see if you can change to nvdec or vaapi and test.
