Re: [Pyobjc-dev] Problem with signature for QTKit Delegate (CVImageBufferRef)

This probably isn't related to the problem you're having, but it's  
something you'd have to fix eventually, so I thought I'd point it out...

This creates a dictionary where the keys are the literal strings  
"kCVPixelBufferWidthKey", "kCVPixelBufferHeightKey", etc. You should  
be using {kCVPixelBufferWidthKey: 640.0, ...} instead, so the keys are  
the values of those constants.
