Chroma keying with kinect v2

I want to do chroma keying. I can do chroma keying with kinect v1. but can't do with kinect v2.

I use kinect PV2 version 0.7.5. This library is very great. unfortunately,CoordinateMapperRGBDepth, example broken, check 0.7.2 version. I wish for kinect PV2 to update.

Please tell me anothe way.
