I'm trying to build a crucial part for my application in which I need to be able to fake a virtual cam video stream. The video stream that I want to fake as a virtual webcam is streamed through my PC, where I can set the video source from my webcam or somewhere from my hdd. To sum up, something I can set as MediaElement.SourceProperty or Image.Source in WPF.
I've seen Vivek's Vcam, a directshow filter here in tmhare.com which seems like it is extremely related to what I'm looking for. But I couldn't find a way to compile it with VS2010, I also don't really know what to do with it. I think I need to change the input pin but how?
Anyhow, to sum up, I'm trying to build a partial code that needs to work like a small version of ManyCam. I'm building a WPF application where I stream the source from a 64 bit PC.
I would also appreciate some sample code for the filter since I have nearly forgotten everything I ever knew about C++ since DirectShow filter needs to be written in C++...
Thanks for everything!

Horonchik
In order to work with directshow filters, you need to have the Windows SDK installed and comiple the BaseClasses solution.
look at: C:\Program Files\Microsoft SDKs\Windows\v7.0\Samples\multimedia\directshow\baseclasses
Afterward you need to add the BaseClasses header files and libs directories to your project properties.
Now your project will know the DirectShow classes and you can start changing the VCam source filter pin.
