Video processing examples

I'm wanting to use a Decklink Quad 2 to take 2 fill and key pairs, composite one on top of the other and output the result on another fill and key pair (ie using 6 of the 8 input/outputs total).

I've have a quick scan through the SDK examples, but these seem to be more about initialising the hardware rather than processing the signals. Are there any example out there that show how to manipulate a video stream before outputting.

thanks!

The OpenGL Compositing sample takes an input, manipulates it then outputs it to another channel - this could be of help. Basically, when you capture frames, they are put into a block of memory in the format you choose (such as RGBA). You can then perform whatever calculations you need and send the modified frame out on another channel.

Regards,
