It seems the OSX webcam functionality is busted in the latest release. So, as a quick fix I reverted this one change in the OpenCV sources: modules/highgui/src/cap_qtkit.mm. After rebuilding OpenCV the camera seems to work normally in all the OpenCV samples which didn't work at all before. |

When I process the frames in a while loop I'm able to work around it by checking if the frame is None and only proceeding with that loop round if that's not the case. I guess the read only fails in the beginning and later iterations are ok. Not really an optimal solution though. I suspect the webcam isn't really ready after cv2.VideoCapture() for some strange reason. |
