This Technote is very helpful, but I fail when trying to create the
suggested PixelBuffer with

err = CVPixelBufferCreate(NULL, width, height, k8IndexedGrayPixelFormat, nil, &tmpPixBuf);

the undocumented error is err==-6680.
But only when I use k8IndexedGrayPixelFormat (and that is what I need).
It does work with k32ARGBPixelFormat.

Any idea what could be going wrong?

k8IndexedGrayPixelFormat is not a pixel format supported by Core Video
