I use OpenCV 2.3.1. I am trying get video from IP Camera (rtsp protocol) but get the following error:

IplImage* frame;   
CvCapture* cam = cvCaptureFromFile("rtsp://admin:[email protected]/defaultPrimary?streamType=u");    while(true)
{               
    frame = cvQueryFrame(cam);          
    cvShowImage("Test", frame);
    if (cvWaitKey(10) == 27){
            break; }
}

In the console I get errors and poor quality video!
