I just bought a new MacBook Pro with OX 10.8. I used the following simple codes to test the webcam with Processing. It is not working in Processing 2.0b3 and 1.5.1. Then I tried both build-in camera and external webcam with Photo Booth. Both work well with Photo Booth, but not with Processing. Is anyone also experiencing the same problem? Is this a Processing problem or my laptop problem? Thanks for your help!
