Q: 

OpenCV on Mac. Takes 2 seconds to read two webcams using cvCapture. Seems slow... Any suggestions...

Hello, I am running OpenCV 1.1. in C on a Mac with two rocketfish webcams (1600x1200) and an iSight webcam (640x480). It takes over 2 seconds to capture a pair of images from one rocketfish webcam and one iSight webcam. This seems slow, especially given that both cameras are reading out 30 fps. Any suggestions... Thanks. Justin
