Capturing Live Video (jit.qt.grab)

Capturing live video is easy for Mac in Max via the jit.qt.grab object.

It basically requires a metronome bang (similar to video playback) to know how quickly it should read and transmit an image matrix. It also has to be sent a specific "open" command to try to access any camera devices that are available.

Getdevlist command grabs a list of devices available to the computer OS. Currently the only device available is the built-in Mac camera. After selecting this input, starting the metronome, and sending the "open" command, the camera is easily captured into the patcher.
