Hello, This might be already resolved, but I'll drop my own used hacky solution, might help.
We require v4l2loopback-linux-module Guix system: ``` : (operating-system : ... : (kernel-loadable-modules (list v4l2loopback-linux-module)) : ...) ``` Running application: ``` : guix shell xdg-desktop-portal-wlr obs pipewire obs-wlrobs -- sudo -E obs ``` Sudo is required the first time only though to get it hooked up. After that it works normally. Then you get to run a virtual camera, and use it instead of screenshare -- Best Regards, Ignas Lapėnas
