Ah, that does sound promising. I'll try throwing a pre-loaded image at the input port when the capture session is stopped, see what happens. Is adding the CVImageRep to an NSImage then passing that to the QCRenderer the most efficient way to handle it btw? Backtrace below (it does appear to crash when setting a port value within QC - see thread 1).
