Open Source projects for Video on Demand server application

What are the preferable software platform and open-source projects for building Video on Demand server application?

I have played a little with VLC. But it has not decent support f开发者_StackOverflow社区or .NET platform. Maybe there are other alternatives better suited for my purpose. If it is relevant, a client side is the Android device. Any thoughts are welcome.

Feng is an open source RTSP server that works for VoD. I don't see what .NET has to do with video on demand, maybe you should say what your purpose is so someone could suggest something more suitable.
