Otherwise users get cryptic errors like so:

A more general way of duplicating that error is by calling startAutomaticCapture twice with the same device number. I haven't tried C++/Java... but it appears to be present in Java, at least.

CameraServer.startAutomaticCapture(dev=0)
CameraServer.startAutomaticCapture(dev=0)

Perhaps add a collection of video sources, and fail if it contains the added source?

I don't get any errors using the same device and it seems to work, do we still want to throw an error if adding the same device twice?
