在IsAvailableChanged上，Kinect Studio的IsAvailable始终为false

Question

Environ：Kinect 2.0 SDK，Kinect Studio，Windows 10，WPF

e.IsAvailailable在通过Kinect Studio（https://msdn.microsoft.com/en-us/library/microsoft.kinect.kinectsensor.isavailable.aspx）开始编程时总是返回false。我认为如果它正在接收数据它将返回true。请注意，即使传感器开始不可用并且从未使IsAvailableChanged处理程序跳闸，BodyReader帧也会到达。请注意，BodyBasics-WPF SDK 2.0示例的行为方式相同。

如果获得e.IsAvailable = false，许多代码示例都会停止。如果您正在使用Kinect Studio并播放，可能是一个不好的举动。

错误？特征？缺乏文件？

针对Kinect Studio的Kinect - IsAvailable = false

针对物理Kinect的Kinect - IsAvailable = true

下面的代码和XAML ......

public partial class MainWindow : Window
{
    private KinectSensor m_kinectSensor = null;
    private BodyFrameReader m_bodyReader;
    private Body[] m_bodies = null;
    public MainWindow()
    {
        this.m_kinectSensor = KinectSensor.GetDefault();
        this.m_kinectSensor.IsAvailableChanged += KinectSensor_IsAvailableChanged;
        this.m_kinectSensor.Open();

        // hook the body stuff
        this.m_bodyReader = m_kinectSensor.BodyFrameSource.OpenReader();
        this.m_bodyReader.FrameArrived += BodyReader_FrameArrived;

        InitializeComponent();
        Msg("MainWindow c'tor completed");
    }

    private void BodyReader_FrameArrived(object sender, BodyFrameArrivedEventArgs e)
    {
        Msg(String.Format("BodyReader_FrameArrived: {0}" , e.FrameReference.RelativeTime.ToString()));
    }

    private void KinectSensor_IsAvailableChanged(object sender, IsAvailableChangedEventArgs e)
    {
        System.Diagnostics.Debug.WriteLine( "KinectSensor_IsAvailableChanged: e.IsAvailable=" + e.IsAvailable.ToString() );
        TextBlock_StatusBar.Text = "KINECT SENSOR STATUS: " + e.IsAvailable.ToString();
    }

    private void Msg ( string s )
    {
        if (s.Length <= 0) s = "ready";
        TextBlock_Msg.Text = s;
    }
}
}
