Re: Delay in source switching and high latency for cameras

I am testing with two different HD cameras; not sure if this could cause a problem. One is a Microsoft HD-3000 camera, the other is a Genius WideCam F100. The tests are performed in a brightly-lit room, so it seems like the main problem is the delay from the cameras having to go to the roboRIO first then going to the computer.

As for CvSink and CameraServer, I will try to use both your suggestions. Thanks!

EDIT: I'd like to ask if and how CameraServer/CvSink can switch between cameras. It seems like the code you had posted displays both cameras at once, although I haven't tested it yet. Since we will be sending and receiving over a radio/wifi connection, our team wants to minimize the bandwidth usage.
