obs-background removal gives segmentation fault.

[anumerico]

Ubuntu 20.04, obs-studio installed through snap, OBS 27.1.3-modified installed through snap. obs-background removal gives segmentation fault. The last relevant lines and error messages for debugging: https://pastebin.com/raw/4KaqtT1W Hope you can help me figure it out.

Seems like there is a PR that may fix the error. I ended up installing obs with apt and adding obs-backgroundremoval with GPU with pr #57.

the same happened on my obs-studio-git on archlinux, assumed its my lack of actual gpu but this issue is still here as opened...

[jpotyka]

I can reproduce the problem on arch using the obs-studio 27.1.3-3 package from the community repository too. After cloning the github repository for obs-backgroundremoval on commit e078002 and building the plugin, obs crashes if you add the filter to a camera with the following error:

[1]    203030 segmentation fault (core dumped)  obs

[OBS1227]

Same.
