Hi. I am trying to understand if I can , at the same time, overlay at least one channel to the videocard and capture it if I want. Just reading the V4L-1 API didn`t helped me to understand why some win32 programs do full frame rate overlay and capture at the same time. Could it be an OS specific resource ? BTW, why does clipping means, in the overlay context ? It does automatic "cut" if the image area is smaller than the capture ? Thanks in advance. __________________________________ Do you Yahoo!?
