Installed Manjaro 2 to 3 days ago, everything went fine, my games were running but there’s one problem, NVENC.
When i try sharing my screen on Discord it lags a lot because it’s using CPU, i can’t use Davinci Resolve, can’t record on OBS and so goes on.
It does work on Windows, 4 months ago i tried Pop OS and i got the same problem
glxinfo | grep OpenGL

and i tried using davinci-resolve-checker :
python davinci-resolve-checker.py
Using locale en_US
DaVinci Resolve checker 2.5.1
Installed DaVinci Resolve package:
Chassis type: desktop
Installed OpenCL drivers: opencl-nvidia
Presented GPUs:
GP107 [GeForce GTX 1050 Ti] (kernel driver in use: nvidia)

All seems good. You should be able to run DaVinci Resolve successfully.
would appreciate any help
Maybe this page could help: Hardware video acceleration - ArchWiki
(found the link here [SOLVED] FFMPEG - Failed to initialise VAAPI connection / Multimedia and Games / Arch Linux Forums)
I remember not being able to normally record with OBS (unstable framerate) in Windows until I suppose I switched to hardware encoder (FFMPEG VAAPI I guess) and OBS was worked fine. I have Intel and AMD GPUs by the way. Then, I tried running OBS in Manjaro, tried to change to the hardware encoder but I was getting an error when hitting the record button:
Starting the output failed. Please check the log for details.
Note: If you are using the NVENC or AMD encoders, make sure your video drivers are up to date.
I suppose I then found the thread on Arch forum and gave a try installing the mentioned driver(s) and I think I got it working just by doing this, I can’t recall exactly.
Yeah, vaapi is for intel and doesn’t works on nvidia proprietary drivers.
After checking the ArchWiki page and running vdpauinfo it shows that my card is compatible:

and after messing around with FFMPEG i got this error:
