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

[Ulrich E. <li...@ne...>]

Adam,

thanks for your hint! i had it initially like this - but then i wasn't  
yet able to import CoreVideo
(needed to comment out 2 @encode(CVTImeStamp) declarations to make it  
work - svn yesterday)

i'll fix this .. but first i need to get to the buffer - data .. then  
i will think and check the rest of the application ;-)


thanks .. and still hoping for a nice little trick to make it work !

cheers Ulrich
