Video frame rate always 90k [closed]

edit

I'm trying to get the frame rate of a captured video but it's always returning 90000 but surely this can't be correct, is there any problem with my code that may be causing this value to be returned?

VideoCapture cap("/home/colin/downloads/20140203_133838.mp4"); // open the video file for reading
  if ( !cap.isOpened() ) {
    cout << "Cannot open the video file" << endl;
    return 1;
  }
  double fps = cap.get(CV_CAP_PROP_FPS); //get the frames per seconds of the video
  cout << "Frame per seconds : " << fps << endl;
  namedWindow("MyVideo",CV_WINDOW_AUTOSIZE); //create a window called "MyVideo"
  while(1) {
    Mat frame;
    bool bSuccess = cap.read(frame); // read a new frame from video
    if (!bSuccess) {
      cout << "Cannot read the frame from video file" << endl;
      break;
    }
    imshow("MyVideo", frame); //show the frame in "MyVideo" window
    if(waitKey(30) == 27) { //if escape key is pressed exit program
      cout << "esc key is pressed by user" << endl; 
      break; 
    }
  }
