最近要做一个通过局域网,进行网络视频的功能开发,之前没有接触过这方面的东西,所以想这里问一下,有没有相关的开源的控件可以用? 在线等~谢谢.

那这个directshow 是开源的吗?
现在有C#版的directshow，就是封装了微软的类库了。
用微软的DShow或者DirectX AuvioVideoPlayBack开发播放器，播放器根据服务器记录的播放文件路径和播放时间播放视频就可以了。附我项目的部分源码：

还有一种更方便的方法是使用QVOD播放组件进行二次开发，QVOD组件是专门供局域网视频播放开发用的。你可以到QVOD官方论坛去，讨论这个开发的不少，而且有不少在线视频点播也是用QVOD开发的，更别说网吧了，QVOD有专门网吧服务器和二次开发组件
