I think all you need to install is OBS studio and v4l2loopback both of which your distribution probably has packages for. Then you just make a scene, add either the “Screen Capture (PipeWire)” or “Window Capture (PipeWire)” sources to it and click the “Start Virtual Camera” button. Anything that supports a webcam will just see it as another camera on your computer you can use.
Heya could you share how you do this trick to screen share ? Would it work on MS Teams?
