DeckLink video input manipulation


This is what I would like to achieve:

Creating flash template with some graphics and with AMCP command which will take signal from one of the decklink duo 2 inputs and then scale and position it in accordance with graphics.

This is probably something I need: ... MIXER_FILL

Of course, flash template with graphics is not the problem, but I need little help to achieve video input manipulation. Some script examples would be very helpful.
