Hi all, I am working on an application that involves real time video editing with Core Framework in Cocoa. For testing we basically have a DVI cam hooked up to a Mac Book Pro and need to be able to edit the stream it produces. I successfully got the video into quick time using QTKit, but am having trouble aquiring the frames with a display link. The example in the Core Video guide shows it initializing the video source from file with this method: * (id)initWithFilePath: (NSString*)theFilePath , but I need to get the frames I can already access into the display link for OpenGL rendering and Core Image effects. If anyone has any ideas or advice I would greatly appreciate it. Thanks in advance!
