this should get you started:

#include "opencv2/opencv.hpp"
int main(int argc, char **argv)
{    
    Mat img;
    VideoCapture cap(0); // 1st cam
    while(cap.isOpenend())
    {
        cap >> img;
        if ( !img.empty() )
        {
            // your processing code here
            imshow("image", img); 
        }
        char k = (char) waitKey(10); // sleep for 10 millis
        if ( k == 27 ) break; // 'esc' pressed
    }
    return 0;
}
