FxTexture & QCRenderer

How can I pass a FXTexture most efficiently to a QCRenderer input port ? All my current attempts failed. I managed to pass a FxBitmap to QCRenderer, but this was too slow and also the R and B channels were mixed up.

Apple's technical note #2143 (http://developer.apple.com/technotes/tn2005/tn2143.html) says that an CVOpenGLBufferRef should work. But I always get this error "warning: passing argument 1 of 'setValue:forInputKey:' from incompatible pointer type".

Is there some updated technical note about how to pass image data (especially a texture) to QCRenderer ?

Christoph
