using DirectShow

Archived from groups: microsoft.public.pocketpc.multimedia (More info?)

I'm getting a "Class not registered " COM error message when trying to
instantiate the DirectShow Filter Graph object. I'm using eVC 4.0, running
with the PocketPC 2003 emulator profile. The code looks like this:

.......
IGraphBuilder *pGraph = NULL;

HRESULT hr = CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC,
IID_IGraphBuilder, (void **)&pGraph);
.......


anybody knows why?

Carlos.
