obs-studio: Temporal AQ not supported

musjj commented 10 months ago

Describe the bug

When trying to record a video, OBS crashes with this error message:

[h264_nvenc @ 0x3403480] Temporal AQ not supported
[h264_nvenc @ 0x3403480] No capable devices found

Steps To Reproduce

Steps to reproduce the behavior:

rm -rf ~/.config/obs-studio
nix run nixpkgs#obs-studio
Pick Optimize just for recording on startup
Add a Screen Capture (XSHM) source
Press Start Recording

Expected behavior

Records normally.

Additional context

OBS studio worked fine like a month ago, so I suspect that there was a regression somewhere. Window Capture (Xcomposite) source also does not display anything on the preview. Probably related.

Could you provide full log? I've just checked on my PC with nvidia GPU but can't reproduce this error, recording for XSHM seems to work fine.

I'm using a legacy nvidia card: NVIDIA GeForce GT 635. Strange thing is that OBS used to work just fine. Not sure if the regression is on OBS or the driver.

looking at error

[h264_nvenc @ 0x4a47100] Temporal AQ not supported
[h264_nvenc @ 0x4a47100] No capable devices found

It looks to me it's nvenc / driver related. I don't have access to any legacy card so can't really check that. I guess you could check if it's nvenc problem by trying to encode something with ffmpeg. But since obs is using ffmpeg I guess it will give same error.

Temporal AQ is available in OBS Studio fir NVENC on NixOS since January 8th 2024 :+1:
