i am dealing with Expensive Live Encoder. It's using camera for streaming video. Discussion board say's will be able to create custom direct show filter and stream data which i need. I cann't know how direct show filter displays within the source listing of the live encoder. I have tryed to make use of some commercial virtual camera also it work's fine, however it cann't use source from network stream.

Summary. I've got a several network streams. I believe which i must to produce virtual camera for every one. But when i've found good examples with direct show filter on C#, i cann't find for virtual camera.

There's a good example here of methods to perform a virtual capture device. You'll have to use C++ to implement it. Additionally, you will need to implement the code to obtain the network stream and parse it into samples for DirectShow to know.
