Thank you, I know this method, but
unfortunately its far to slow. Sending a Matrix of 640 x 480 Pixels is only transferrable with 10 frames per second.
The idea to send a picture from one computer to the other would be to do a videoperformance on one Computer and record it on a second one.
Any other proposals how to get video from one laptop to another?
Depends which kind of hardware you are using and how much money you want to spend. If your video processing is not that heavy you can try to capture with ishowu, snapz or any other screen capturing software. However, you might run into different problems such as dropping frames during the capture.
Second option might be to get an editing card like the Intensity Pro. There are several post on the forum about the topic
