I have a QC composition, using just a VideoInput and a Sprite.
The VideoInput's "Image" output is published.
I run this from a Cocoa app, rendering it into a QCView.
When I access the image using:
    id anImage=[qcView valueForOutputKey:@"Image"];
...the object in anImage is an NSImage.

Is there any way to make it so I can get back a CIImage instead?
I just want to feed anImage into a CIFilter. I'm trying to avoid using:
[CIImage imageWithData:[anImage TIFFRepresentation]]

No, that's not possible, -valueForOutputKey: always returns NSImages for image ports

Hrm ... any hope of a CIVideoInput CIFilter on the horizon?
