title: Kinect v2, read out data from .xef files
body: <p>I have collected a bunch of videos using Kinect for windows 2 using the kinect studio with file extension .xef.</p>
  
  <p>Now I want to write a program to load data from them and just playback or save as another format, but I have found little resource to doing so, is there any useful resource to do that?</p>
