用kinect工具箱記錄器啓動時出現故障

Question

我第一次與kinect.toolbox一起啓動了kinect。我正在嘗試使用kinect.toolbox記錄器以及隨microsoft developer toolkit提供的用於kinect sdk v1.8的顏色基礎知識wpf c＃。但是，當我點擊開始錄製按鈕時，它不會創建一個.recorded文件，如this answer中所述。你能幫我，告訴我我做錯了什麼嗎？

下面是我的代碼：

Answer 1

我不能看到調用this.recorder.Record(colorFrame)在private void SensorColorFrameReady(object sender, ColorImageFrameReadyEventArgs e)方法。嘗試添加此。
