I am using the Kinect 2 with the newest available SDK version 2.0. Everything works except IR, tested it with both SDK infrared demo example and Kinect Studio, both result in a black screen. I also looked at the code and capturing Kinect IR frames does not result in any errors, it just consists of all minimum values.
This is quite weird, as I thought IR was used to calculate depth and I can successfully read depth information. Also, I checked (with my cellphone camera) that the IR emitter is turned on and off correctly, just data is not received correctly for some reason.
After encountering the problem I made a fresh install on another computer, as I suspected I had broken my system somehow. I got exactly the same results after installing Kinect SDK. Everything except infrared works.
Has anyone seen this kind of behaviour before?
