c# - Update the video source device list

Question

It seems the device list will be created only once at startup. Is it possible to update the video source device list during run time. Unfortunately, I can't find a method to do this.

Answer 1

如果您从一开始就进行枚举（而不是重用您已经拥有的枚举器实例），则会更新视频捕获源列表。

您可以通过启动 Windows SDK GraphEdit、列出过滤器、然后连接新设备并重新检查列表来见证这一点，而无需关闭 GraphEdit 应用程序。
