Opening OBS not working

My PC Specs are
AMD Ryzen 5 4600G
NVIDIA GeForce GTX 1050
16GB DDR4 Memory

My arch kernel is 6.3.6-arch1-1, my bash is bash 5.1.16, my desktop enviroment is Cinnamon.

Not sure what here you need but im sending it on. My issue is. Whenever I try to open OBS, nothing happens. I ran obs --verbose, and this is the output I got.

Re: Opening OBS not working

Segmentation fault (core dumped)

https://wiki.archlinux.org/title/Core_d … _core_dump

Also, from context:

vainfo
LIBVA_DRIVER_NAME=vdpau vainfo
LIBVA_DRIVER_NAME=nvidia vainfo

And try to start obs w/ the working (if any) LIBVA_DRIVER_NAME exported.

Re: Opening OBS not working

Not "printenv", "vainfo" - and yes, OBS crashes in the VAAPI code.
W/ https://github.com/obsproject/obs-studio/issues/8056 OBS seems incompatible w/ libva-vdpau-driver

Edit: the upstream bug suggests to try https://aur.archlinux.org/packages/libva-nvidia-driver instead.

okay thank you. to install it do i just git clone it and makepkg? or do i need to do anything special to actually enable the drivers

Re: Opening OBS not working

◉ pacman -F vainfo
community/libva-utils
    usr/bin/vainfo

https://github.com/elFarto/nvidia-vaapi … -variables but it should™ work OOTB, w/o the driver, OBS might also just use VDPAU and apparently you can configure the HW acceleration, https://wiki.archlinux.org/title/Open_B … celeration
