I just tried it out with Jitter and the video coming through was 1-dimensional, ie the same x-value was being seen across the y-axis. Not sure why this is, but perhaps not the best solution in this case. Haven't seen anything else that can do this though.
Just thought I'd top this thread, since it's been about 6 years now.. This seems like something a lot of people would potentially want to do (or already be doing) with Jitter... Has anyone solved an open-source solution for the time being?
