I did this way back when (~'93) with Sun's VideoPix video frame grabber device (/dev/vfc0). Cron would launch the program every minute and the code would then opened the device, set the format (size, video format, color, etc), grab a frame and spit out a YUV image. At that point I would run PBM to clean it up and spit out a (then) GIF image. Is there something like a frame grabber device for the 848 cards that could be managed in much the same manner?
