[Swlug] Looking for a software suggestion

[Rhys Sage]

I have Simple Screen Recorder and Kdenlive. They do not seem to do what I'd like to do which is to record the screen and superimpose a video on the top right that's being shot by my webcam on top of that recording so that it's all live. Think of the same kind of thing that "A Different Bias" does on his YouTube channel but with a live and changing screen as opposed to just a picture with a webcam  image on the side.

Is anybody aware of any free Linux software that'll do that? I'm using Mint 20.3 (Uma).
