Initializing VisualGestureBuilderFrameReader with a MultiSourceFrameReader stream RRS feed

  • Question

  • I'm trying to merge code from a OpenMultiSourceFrameReader XAML example with Ben Lower's "FlappyArms" VGB console example from a few weeks ago.

    My current Windows_Loaded method looks like this:

            private void Window_Loaded(object sender, RoutedEventArgs e)
                _sensor = KinectSensor.GetDefault();
                if (_sensor != null)
                    _reader = _sensor.OpenMultiSourceFrameReader(FrameSourceTypes.Color | FrameSourceTypes.Depth | FrameSourceTypes.Infrared | FrameSourceTypes.Body);

                    vgbd = new VisualGestureBuilderDatabase("FlappyArms.gbd");
                    vgbfs = new VisualGestureBuilderFrameSource(_sensor, 0);
                    foreach (var g in vgbd.AvailableGestures)

                    vgbr = vgbfs.OpenReader();

                    vgbr.FrameArrived += vgbr_FrameArrived;
                    _reader.MultiSourceFrameArrived += Reader_MultiSourceFrameArrived;

    Both events vgbr.FrameArrived and _reader.MultiSourceFrameArrived  are triggered.  The vgbr.FrameArrived event arg is always null.  The Reader_MultiSourceFrameArrived works fine.  I suspect the line: vgbr = vgbfs.OpenReader(); is incorrect.

    What is the correct way to call visualGestureBuilderFrameSource.OpenReader if I already have a sensor source open?
