You could build something based on lavrec, set up for timelapse recording, limited to one frame per file, and a chain that process each of the grabbed files through lavtrans and either pnmtools or ImageMagick. Or you could try Motion, which has such a mode. http://motion.sourceforge.net/ > When I try to take a shapshot from /dev/video I get the error message: > DC30[0]: setup_window() - frame buffer has to be set first. > > I suppose this has nothing to do with the framebuffer (/dev/fb)? Correct, it has to do with the way a grabber has to talk to the driver, as the driver really, really prefers to deliver an mjpeg picture, while most grappers expect it to be a raw dump. /Sam ------------------------------------------------------- Using Tomcat but need to do more?
