Is there any example to show how to write a Direct

Question

I want to capture a current frame and its previous one to do analysis and produce a new frame to show. Is it to say I must write a transform DirectShow filter? But I am a newbie to DirectShow. I was confused by MSDN's lots of documents. So I wonder if there is any simple example to show how to do it.

Thanks. Cook

In the directshow samples that come with the Platform SDK you, at least, always USED to get examples on how to make all sorts of filters. I can't believe they would have removed that. It made DirectShow almost usable :)
