Hello all,
I use OBS for recording my screen, and I'm trying to set up HEVC encoding on my GPU (Vega 8, it is supported) to save space. Since OBS's standard output only supports H.264 with VAAPI, I have used a custom FFmpeg output with the hevc_vaapi encoder. I added -vaapi_device /dev/dri/renderD128 -vf format=nv12,hwupload to the encoder settings as those are required when I use VAAPI via FFmpeg. Here is a screenshot of my settings:
And here is my log file from when it crashed. In that run, I tried formatting the encoder settings differently (I wrote vaapi_device='/dev/dri/renderD128' vf='format=nv12,hwupload') but that did not fix the issue. When I click "Start Recording," after about half a second OBS crashes (it has a segmentation fault).
Can anyone help me figure out what is going on? I know there is a patched version of OBS that adds HEVC support to the built-in VAAPI encoder, but I would like to keep using the official releases if possible. I'm using OBS 25.0.8-2 and FFmpeg 4.3.1 on Arch Linux running on a Ryzen 3500U.
Thanks in advance!
