Believe it or not I had that originally and it didn't work. I must
of had a type-o in the function header that I was passing to
respondsToSelector.
One way to avoid that sort of problem is the "ifResponds" Higher Order
Message:
[[_delegate ifResponds] SGDecompDataProc:pixelBuffer
trackingFlags:decompressionTrackingFlags
displayTime:displayTime
displayDuration:displayDuration
validTimeFlags:validTimeFlags]
This will send the message if _delegate responds to it.
Cheers,
Marcel
