It is a problem in the QTKit bridgesupport, where `captureOutput:didOutputVideoFrame:withSampleBuffer:fromConnection` is not defined. This means it's defintely not something you are doing wrong (and it's not MacRuby's fault either – it has no way, without proper BridgeSupport support, to know the actual type of the parameter)
This has been fixed in BridgeSupport already, and should be released soon(-ish). However, I don't think there is any workaround in the meantime, except waiting for the BridgeSupport update. Thanks for giving more details btw :-) -- Thibault Martin-Lagardette On Aug 23, 2010, at 11:12, Steven Parkes wrote: >> Can you add a little more information to the issue maybe? > > The callback is getting most of its parameters typed correctly, but one of > them seems to be not.
