Nvidia NVENC not working with applications

Worked for me, thanks!

i have found a way to install nvidia
in this forum some where but i forgot to book mark
but i have commands in my history
i am using a nvidia 1660 ti mobile (optimus laptop with intel integrated gpu and 1660ti mobile) i ran into similar issues but installed finally
OBS studio is also working with NVENC
to update

IMPORTANT:: update all packages before doing and reboot
without updating all packages and kernels
-------------------------> you cant install nvidia - 450 without updating the existing packages
–>update packages before doing this

NOTE : remove the current drivers using MHWD command line and install

  1. sudo mhwd -i pci video-modesetting (or your driver name)
  2. sudo mhwd -r pci video-hybrid-intel-nvidia-440xx-prime (or your driver name)
  3. sudo mhwd -i pci video-hybrid-intel-nvidia-450xx-prime (or your driver name )
  4. reboot

thats it
it worked for me

Is there a solution for hybrid graphics for this? Cause I’ve tried everything suggested and NVENC still won’t work. Here’s my system info:

Is the ffmpeg/nvenc still broken? Downgrading and switching to the testing branch didn’t work but x264 did. That’s using the CPU and I’d rather not do that… My system is still rolled back to kernel 5.6 for now. I’ve upgraded but again, only the x264 only work and not the nvenc.

Maybe a fresh install will fix this.

NVENC (at least in OBS) seems to work with the 450.xx series driver and ffmpeg n4.3.1, on Linux 5.4.

Yeah, I’m still on 440.

So you’ve upgraded just ffmpeg and the drivers only, right? Also you used mhwd or directly from NVIDIA’s drivers?

I don’t exactly remember, I switched to a different branch at about that time. I used mhwd.

There doesn’t seem to be a 4.2.4 option when I try to do it, so I tried 4.3.1 (which I think someone mentioned worker for them) and it gives me the error:

error: failed to prepare transaction (could not satisfy dependencies) :: unable to satisfy dependency 'libx264.so=160-64' required by ffmpeg

It’s been more than a month and you’re still struggling guys?
I have Nvidia 450 (removed 440 then installed 450 from KDE’s System Settings / MHWD), and I have OBS, I can record with NVENC without any issue. I don’t understand why you’re still trying to figure out how to downgrade to Arch’s old package when it was never needed, this has been quickly fixed (couple days for sure on Testing branch) by pushing 450 drivers to Stable after the issue has been identified.
