I try to capture the video under NTSC with 30 fps. Basically, the consuming time for each frame should be (1/30) s which means 33ms. I open the device and use select() function to wait for the incoming frame to capture. I try to measure the interval among every capture and found the consuming times are sometimes 60ms above, which is over 33ms largely. Did you see something like this on your system ? Or any idea for this? Thank you..
