You can add SampleGrabber to your DShow filter graph and use it to capture video frames.

Some links: MSDN, CodeProject

libvlc bindings might could do it for you

If you use GraphEdit, from windows SDK, you should be able to access audio capture devices and add that and then do what you want with it. From there you can go into DirectShow or DirectShowNet and add these filters easily to mimic what you have in Graph Edit
