here's a simple videoloop

#include "opencv2/core/core.hpp"
#include "opencv2/highgui/highgui.hpp"
using namespace cv;

int main()
    VideoCapture cap(0); // get 1st cam. you can also put a string with a videofile here.
    while( cap.isOpened() )
        Mat frame;
        if ( ! )

        // your processing here

        int k = waitKey(10);
        if ( k==27 ) // esc.
    return 0;
