(UE4-27) Webcam Input selected from Menu

Hello there!

I’m currently working on a project to create a greenscreen effect for a science exhibit.
I’m looking to allow my team easy webcam selection in case they need to swap machines or whatever. Basically I want to set calibration to be as easy as possible.

I can assign my webcam to the media playlist in editor, but I’m not sure how to allow a user to select a webcam during runtime. Has anyone configured something like this before?
