[PD] chromakey range/value

[ian campbell]

Hi
I'm having trouble understanding how to give pix_chroma_key the colour I
want to key out.
Right now by playing with the value and range number inputs copied from the
help patch
gives me in effect a luma keyer. How can I key out a green screen?

Here's the patch I have been building on.. I tried to hook up a colour
picker from the mtl abstractions
but it doesn't seem to do much. Uses pix_video from 2 pci capture cards.
