Camera not connecting to app


I am following Boisy Pitre iOS/macOS tutorial and I am stuck. It runs but my webcam does not seem to connect and I do not have the video stream displayed. Anyone can help me?


I seem to be having the same problem. I can see the light from the webcam is on, but there is no video being shown. I got the following errors. I can’t see to find useful answers online.
