What Filter Categories to make screen capture using Directshow?

In开发者_如何学编程 msdn Filter Categories, What categories to be chosen to make screen capture video link text

I'm not sure if I'm getting you right. Do you want to know which is the category where video capture filters are in? Then have a look at CLSID_VideoInputDeviceCategory. Or are you looking for a filter that captures "screenshots"? Because there is no such filter by default but several examples around the net.

uscreencapture puts theirselves under "Video Capture Sources" but I suppose it's arbitrary...
