Thanks Alexandre and Simon,
It sounds like technically the task is a trivial one, thanks for the tips. In terms of latency, I get the impression this is a function of the video capture method used... @Simon, can you tell me which PCI card you are using? This project is to port a piece originally done with Max/Jitter to a Pd-based system. The main complaints they had were video quality and latency, so those are problems we need to solve.
