contcapt - a converted OpenGL version of the VL contcapt program. contcapt takes video data via VL and uses OpenGL to display it. It shows how to use the ABGR_EXT pixel extension to allow OpenGL to display video data without swapping the order of the pixel values and how to use the glPixelZoom command to draw the frame from top to bottom (like video) instead of the default bottom to to order of OpenGL. where arguments may be:\n" -b n use n buffers\n" -c n capture n frames\n" -d turn off double buffer mode\n" -D turn on debug mode (displays more information)\n" -f fast mode (no display)\n" -F specifies field (or non-interleaved) mode\n" -g wxh frame geometry (ex. 640x480)\n" -i n report statistics every n frames\n" -m monochrome input\n" -n device number\n" -r n set frame rate to n\n" -t turn on timing statistics gathering\n" -v video source (depends on hardware;see release notes)\n" -w 32 bit 'wide' RGB pixels\n" -z d/d set zoom factor to fraction 'd/d'\n" -h this help message\n" *** not all options were converted in the port to OpenGL eg. operations that result in X window management such as the resize and placement of the window are not converted as well as some of the pixel formatting options.
