I have a bunch of C code written using vfw api to capture video from a winnov card.
I'd like to use this same code to capture video from 1394, USB and IP cameras.
Does the vwfwdm allow me to do this ?

I've done some testing with Virtualdub and I can see in the device selection
that it allows me to connect to the WDM device, so I think it's installed okay.

When I try to connect to the same device from my code, it always fails.

Is what I'm trying not possible, if so what is the point of the wdm wrapper ?
