ok you can try two things in dshowvideosrc.c,:
just replace IID_IFilterGraph by IID_IGraphBuilder
(IGraphBuilder inherit from IFilterGraph)
I think it will not resolve the problem so you also can try:
in dshowvideosrc.c before "hres = CoCreateInstance (&CLSID_FilterGraph, ..."
create first a capture graph builder 2:
HRESULT hr = CoCreateInstance(CLSID_CaptureGraphBuilder2, NULL,
CLSCTX_INPROC_SERVER, IID_ICaptureGraphBuilder2, (void**)&pBuild );
then if it fails report an error.
after ""hres = CoCreateInstance (&CLSID_FilterGraph, ..."
do this:
pBuild->SetFiltergraph(pGraph);
(other infos:
IGraphBuilder *pGraph = NULL;
ICaptureGraphBuilder2 *pBuild = NULL;
