Sir, I am using two buffers for capturing frames from a grabber card. Here is what I use. capture frame 0 loop catpure frame 1 sync frame 0 use frame 0 capture frame 0 sync frame 1 use frame 1 goto loop: I am getting a speed of about 50 miloseconds per image. It means 20 frames per second. Can any one suggest, how to increase this speed. I am told that if we use more buffers we can go upto 60 frames per second. Please tell me how?
