Hi Friends, Once we enable the experimental graphical driver, opencv 3.1 imshow does not work, it does nothing and the very basic program hangs for infinite. My sample code is as pasted below:

include "opencv2/opencv.hpp"

using namespace cv; int main(int, char**) { VideoCapture cap(0); // open the default camera if(!cap.isOpened()) // check if we succeeded return -1; Mat edges; namedWindow("edges",1); for(;;) { Mat frame; cap >> frame; // get a new frame from camera cvtColor(frame, edges, COLOR_BGR2GRAY); GaussianBlur(edges, edges, Size(7,7), 1.5, 1.5); Canny(edges, edges, 0, 30, 3); imshow("edges", edges); if(waitKey(30) >= 0) break; } // the camera will be deinitialized automatically in VideoCapture destructor return 0; }
