What did you search for? v4l2 is pretty well known as the driver stack in linux for webcams. If you just search that you'll get an answer that makes sense.
xshm is a little more obscure. It's referring to the specific API used by OBS to retrieve frames from the X server. This is one of those moments where anyone who works in marketing would start screaming. Instead of just saying that its the "desktop record" option, it decides to use the name of the API being used and expects the user to understand. A "user friendly" application would avoid mentioning v4l and xshm, and instead reference webcam capture and desktop capture, respectively. Unless you are a software developer, xshm is a pretty meaningless term.
