  • waitKey(0) should wait forever.
  • did you build your own opencv libs ? (there are no prebuilt ones for 32bit, afaik)

I think 3.0.0 is the last one for win 32. After I see a "left.." on the screen I take my glasses off and press a key .But i see myself with eyeglasses on the captured image ? Thnks.
