Autonomous Vehicles DRIVE PX 2 DRIVE - Linux

Hi
In the /admin123/px2/5050bL_SDK/DriveSDK/drive-t186ref-linux/samples/nvmedia/ipp_raw$ .I use the command line:./x11/ nvmipp_raw-cf drive-px2-autocruise. Conf-c dvp-ss3322-rccb- raw12-1920x1208-ab-d 0 -aggregate 1 -nvplugin can see clear video images on the display screen. Now I want to use opencv to get the video data inside the app_raw routine and show it, does anybody know how to change the code inside the routine?
