[OBS]Failed to load NVENC codec

I'm getting this error while trying to start recording using obs studio.

Earlier it was working fine. Maybe this is bug?

EDIT: My card doesn't support nvenc https://developer.nvidia.com/video-enco … matrix-new.

Re: [OBS]Failed to load NVENC codec

I've been having some issues unrelated to yours with this new driver. This was a recent update I believe about 4 days ago. If it's working before, this might be an issue with this new driver.
I've downgraded to the old driver to  fix my own problem so I can't test the nvenc for this new driver. I don't have a better answer than to downgrade to the older driver.

Re: [OBS]Failed to load NVENC codec

The new nvidia 450.57-2 build with the recent linux 5.7.8 works now. Would you be able to confirm this works for you as well?

Re: [OBS]Failed to load NVENC codec

I would try out and let you know.
[EDIT] : Still getting same error additionally saying to close other recording software but I don't any have other.

Re: [OBS]Failed to load NVENC codec

I had this problem with nvidia 450.57-3 and linux 5.7.8

Updating to linux 5.7.9 has fixed the problem.
