Realtime video delay of input video

Hi
Not sure at all what is possible with MadMapper but I have a client request to create a 2-3 second video delay of a masked video (video with alpha) feed(from a webcam).

I am going to create this masked video input using Kinect and background subsitution method so the person is isolated from the background.

I was thinking I might be able to feed this video to MadMapper which will display the unaltered Live RGB video in the background.
I can use this Unity plugin to accomplish the communication from Unity to MadMapper https://github.com/keijiro/KlakSpout

The challenge for me is how do I delay the masked video input 2-3 seconds?
Does MadMapper have the ability to somehow buffer input video?

MadMapper won't do video delay. Maybe you'll find an application getting the camera input, doing the delay and sending to Syphon, or an application getting Syphon output from madmapper (show the camera), applying a delay and sending back a syphon stream. No idea...
