title: How to play a .mov from a rtsp
body: <p>i am trying to play from a wifi camera that streams on .mov file using rtsp, i get the image but it arrives distorsionated, sometimes pixelates sometimes green and sometimes without errors, while i am playing it i get the following messages in the bash:</p>

  <p>to see the images the camera captures i am using this</p>
  
  <pre><code> cv::VideoCapture capture("rtsp://192.168.1.254/sjcam.mov");
  if (!capture.isOpened()) {
          //Error
      }
  
      cv::namedWindow("TEST", CV_WINDOW_AUTOSIZE);
  
      cv::Mat frame;
  
      for(int i =0; i&lt;50000;i++) {
          if (!capture.read(frame)) {
              //Error
          }
          cv::imshow("TEST", frame);
  
          cv::waitKey(30);
      }
  </code></pre>
  
  <p>I do not know what else can i do, or where is the problem, i have tried to play .mov videos using opencv and i do it without problems, so i suppose i am doing something wrong with the rtsp
  thanks a lot</p>
