title: Mirrored image when capturing from webcam
body: <p>I'm capturing images from a webcam using code based on the example from <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/dd407288(v=vs.85).aspx#example_code" rel="nofollow">http://msdn.microsoft.com/en-us/library/windows/desktop/dd407288(v=vs.85).aspx#example_code</a></p>
  
  <p>It works fine except one strange thing: the image is mirrored along its x-axis, means it is top-down (but not rotated by 180 degrees).</p>
  
  <p>So how can this happen? Is there a DirectShow option that could cause such a behaviour?</p>
