Hello everyone!
First time using DirectShow.NET. Now I want to get all resolution ratio for my cameras. But I don't know how to use ICaptureGraphBuilder2.FindInterface() function. Can anybody tell me how to use this function, especially what to pass to the 3rd parameter.
If anyone has a function to get resolution ratio, please tell me, Thanks a lot.

The third parameter of ICaptureGraphBuilder2.FindInterface is the starting point in the graph from where the method try to find the provided interface. I don't remember if you can pass null to perform a whole graph search.

Regarding your main problem, I found that post that should be very helpful (scroll down): http://stackoverflow.com/questions/7497559/how-to-list-camera-available-video-resolution
