creating direct show filters and sample grabbers?

[fguihen]

i have to make an image move to a playing mp3 using c# and directShow. i have found out that i will have to create a custom filter and possibly a sample grabber from which i can get data to make my image move to a beat. i dont know anything much about directShow and am only learning c#. anyone do this before? can anyone help?

DirectShow is not a part of Managed DirectX right now. You might be able to find some wrappers for unmanaged version.

what exactly does a wrapper class do? how does it work?
