我需要什麼控制才能顯示攝像頭的視頻？

我想集成攝像頭，並使用Aforge.NET框架。我需要什麼樣的控制才能顯示攝像頭視頻。我的簡單程序將獲得網絡攝像機，將它放在組合框中，當我點擊「確定」時，我可以看到相機正在運行，但我沒有看到視頻。 C＃/ WPF我需要什麼控制才能顯示攝像頭的視頻？

我們正在使用VLC點網控制。這工作就像一個魅力，也與網絡攝像頭：http://vlcdotnet.codeplex.com/

這裏沒有內置到WPF中。但我可以推薦耶利米莫里爾的WPF MediaKit，你可以在http://wpfmediakit.codeplex.com/

的VideoCaptureElement在工具箱找到可以從任何捕捉源（其中包括任何網絡攝像頭）到WPF渲染視頻。
