What version of ofxQTKitVideoPlayer are you using under 64bit? I had the impression that it was not possible to run this under 64bit (and I'm not able to find a version that i'm able to compile).
QTKit can run in 64 or 32 bit, it's the new implementation of quicktime. Have you tried this version?
Otherwise, maybe try this one?
There may be some legacy quicktime calls in these addons that aren't in QTKit. What errors are you getting?
The problem is the "Unknown type name 'QTVisualContextRef'", and QTVisualContextRef is used by all the implementations as far as i can see.
Okay, it was what I assumed. Just hoped you had a workaround. But I think that this library will be able to help me compile in 10.7 sdk though!
