Streaming over RTSP (Bug #3494)

Hello guys !

I have been trying to access an IP Camera through RTSP in Visual Studio 2012. Here is my code:

VideoCapture cap("rtsp://IP_ADRRESS/play1.sdp/?tcp");

if (!cap.isOpened()) {
cout << "Cannot open the video file" << endl;
return -1;
}
double dWidth = cap.get(CV_CAP_PROP_FRAME_WIDTH); double dHeight = cap.get(CV_CAP_PROP_FRAME_HEIGHT); cout << "Frame size : " << dWidth << " x " << dHeight << endl;

namedWindow("MyVideo",CV_WINDOW_AUTOSIZE);

while (1) {
Mat frame;

bool bSuccess = cap.read(frame); 
{
        cout << "esc key is pressed by user" << endl;
        break; 
   }
}

if (!bSuccess) 
{
         cout << "Cannot read a frame from video file" << endl;
         break;
    }

imshow("MyVideo", frame);

if (waitKey(30) == 27)

When I run it in debug mode, it works just fine, but when I run it in realese , it doesn't work. Any ideas ?
I was able to access the camera using only ffmpeg.

if i didn't post any useful informantion, let me know !

Thanks a lot !
