I am working on a project which uses OpenCV to do motion detection. I would like to use the RPi camera module as input, but at this time I can only use an external Webcam. Do you have any development status and time scales on when a suitable V4L drive will be available for Pi? I understand that V4L driver is a requirement to be able to use OpenCV. I will soon be getting to point where I will not be able to progress the way I want to.
