How can I find out a DirectShow filter's clsid?

Question

I want to use the LAV Decoder filter in my application, but i can't figure out the clsid.

Where do I find it? Is there a header file i can include?

Do I have to insert the clsid guid manually?

It's better to hard code the GUIDs in your code. You can find out all DirectShow filter GUID with GraphStudioNext (a replacement for GraphEdit).
