Неисправность при запуске с помощью kinect toolbox recorder

Question

Я начинаю с kinect в первый раз вместе с kinect.toolbox. Я пытался использовать рекордер kinect.toolbox вместе с базой цветов wpf C#, предоставленной с помощью инструментария для разработчиков microsoft для kinect sdk v1.8. Однако, когда я нажимаю кнопку начала записи, она не создает файл .recorded, как описано в this answer. Не могли бы вы помочь мне и рассказать мне, что я делаю неправильно?

Ниже мой код:

using Kinect.Toolbox.Record;

Я не могу видеть вызов this.recorder.Record(colorFrame) в методе private void SensorColorFrameReady(object sender, ColorImageFrameReadyEventArgs e). Попробуйте добавить это.
