The call to cv2.VideoCapture(camera_id) blocks when the camera is busy. It returns once it has been released and can be acquired by the current call.

The OpenCV API doesn't seem to have any way of avoiding blocking. Perhaps calling this function from another thread, and timeout it, could solve the problem. Explore also threading.Timer.
