Thank You for Every One, I used Only this simple Code and All this is good, This one worked perfect

in main(){ cv::VideoCapture cap("K:/OpenCv/DataSetCar/WP.mp4"); if(!cap.isOpened()) // check if we succeeded return -1;

         Mat edges;
         namedWindow("myFrame",1);
         for(;;)
         {
             Mat frame;
             cap >> frame; // get a new frame from camera
               imshow("edges", frame);
             if(waitKey(30) >= 0) break;
         }
         // the camera will be deinitialized automatically in VideoCapture destructor
         return 0;

}
