2 Cameras Setup (Lifecam HD 3000)

[BenBernard]

We are also streaming only one camera at a time. There are a couple of tricks to this:

1) In Robot.init, instantiate a USBCamera instance for each camera. Then when you call CameraServer.startAutomaticCapture, pass in the default camera.

2) You'll need a Command, probably triggered by a button, to switch cameras. The natural thing to want to do is to simply call startAutomaticCapture again, passing in the other USBCamera instance. That won't work, because of the way startAutomaticCapture is implemented. To solve this, you'll have to create your OWN version of CameraServer (copy, paste, rename), and change the startAutomaticCapture to stopCapture on the camera already in use, if any (m_camera), set the new camera, then startCapture on the new camera.

If you need more details, let me know.
