title: Setting frame size of QuickCam Pro 3000 with OpenCV?
body: <p>I'm using OpenCV 2.4.6 to grab images with my old Logitech QuickCam Pro 3000 webcam. Using <code>VideoCapture::set( CV_CAP_PROP_FRAME_WIDTH, ... )</code> I'm not able to set the value of the width (idem for the height). <code>set(...)</code> always returns <code>false</code>.</p>
  
  <p>Is it normal?</p>
  
  <p><strong>P.S.</strong> I'm on Linux (<em>kubuntu</em>) and it seems to use V4L.</p>
