Track events such as pause or ended with VideoViewer

I have implemented videoviewer in my site, and I want to listen to events such as pause, play ended etc. The documentation doesn't really explain how this is done.

My code to implement video is as follows:

  var videoViewer = new s7viewers.VideoViewer({
    "containerId":"s7viewer",
    "params":{
          "asset":"Scene7SharedAssets/Glacier_Climber_MP4",
          "serverurl":"http://s7d1.scene7.com/is/image/",
          "videoserverurl":"http://s7d1.scene7.com/is/content/"
            },

          "handlers":{
                "initComplete":function() {
                      console.log("init complete");
                      var test = s7viewer.playback;
                      console.log(test);
                },
  "trackEvent":function(objID, compClass, instName, timeStamp, eventInfo) {
    //identify event type
    var eventType = eventInfo.split(",")[0];
    console.log(instName)
    switch (eventType) {
      case "LOAD":
        //custom event processing code
        console.log("loaded")

        break;
      //additional cases for other events
}
}
            }
    })

    videoViewer.setHandlers({
          "initComplete":function() {
                 console.log("init complete 2");
          },
          "trackEvent":function(objID, compClass, instName, timeStamp, eventInfo) {
                 console.log(objID);
                 console.log(compClass);
                 console.log(instName);
                 console.log(eventInfo);
                 console.log(timeStamp);
          },
    })
    videoViewer.init();

When you pause the video eventInfo has no value, how can I detect when video has been paused. here is the documentation:
