Currently, I haven't had any success using my computer webcam on multiple layouts.

If this is possible, I would love for someone to explain it to me. Right now, when I try to add my webcam to a second layout it doesn't show an option to use the same device, "Facetime HD Camera", I'm using on my "host" layout.

I think this would be helpful to streamers who aren't looking to invest in a second webcam. Especially because I have one that works.
