This is a simple question. I am trying to accurately see how many frames i can grab and write per second using the v4l interface on my slow mule box. If my understanding is correct, with mmap, VIDIOCSYNC, frees a specified frame and then the driver fills the mapped memory with a video image. Is there anyway for me to be notified that the frame is full? How can I be sure that after I call VIDIOCSYNC that the buffer is full b4 I start working with it? Thanks yall. -kali
