The first ‘valid’ number is supposed to be 1. Indeed the Win32 plugin explicitly fails for 0, the linux version subtracts 1 from the provided number and would fail with 0, and the RISC OS version… doesn’t exist.

In platforms/iOS/plugins/CameraPlugin/AVFoundationVideoGrabber.m it looks like the list of available devices is left 0-based and this would probably explain your problem.
