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?
