Are you writing a macOS native app or attempting to compile a catalyst app?

Code Block AVCaptureDevice.DiscoverySession(deviceTypes: [.externalUnknown], mediaType: .video, position: .unspecified)

Gets all USB cameras for me. Not sure about a FaceTime Camera on a Laptop.

we use mediaType:AVMediaTypeMuxed, although I would have thought that AVMediaTypeVideo would include Muxed devices.
