title: Opencv munmap error
body: <p>I am trying to implement the following code:</p>
  
  <pre><code>#coding=utf8
  
  from opencv.cv import *
  from opencv.highgui import *
  
  # Avame kaamera
  capture = cvCreateCameraCapture(0)
  
  while True:
      frame = cvQueryFrame(capture)
      cvShowImage("Aken", frame)
      char = cvWaitKey(33)
  </code></pre>
  
  <p>but I am getting some kind of a munmap error. Can anyone point me to the direction of the problem that might be occurring in my coding?</p>
