New install: Coredump on Arch Linux, nvidia

dts · Jul 25, 2023

I need help with Arch Linux - obs-studio 29.1.3-1 (x86_64). I installed it for the first time and it fails to launch. My system is fully up to date. Here is the log file:

The journal further shows this coredump:

I am running the latest version of libva:

Code:

$ pacman -Qi libva
Name            : libva
Version         : 2.19.0-1

Temporary Workaround:

obs launches correctly using `LIBVA_DRIVER_NAME=dummy obs`

I would like to be able to use hardware-accelerated video encoding.

The following info might be helpful too.
