That should work so if there is a bug, it is in the code. -
createSnapshotImageOfType: does work with CVOpenGLBuffer (or at least
it works on my machine by doing a quick modify of the Offline
example). Please go to http://developer.apple.com/bugreporter and file
a bug if the valueForOutputKey:ofType: call returns nil; Or let me
know if you don't, so I can file it myself.
Thanks!

Developers,
The documentation for QCCompositionRenderer
valueForOutputKey:ofType: says that I can request a published image
as any of a number of types. One of the types listed is
CVOpenGLTexture however every time I try to use it, I get back nil.
CVOpenGLBuffer, CIImage, and QCImage all work fine.
Is that a bug in the documentation perhaps?
Thank you.
