I am working with VS2005 on a pocket pc. I am trying to access my camera with
Directshow. When I list my source filters I get "HTC Source Filter" with GUID
{ 0xA06DF275, 0xC4F3, 0x46C7, { 0xB5, 0x20, 0x3A, 0x16, 0xB3, 0xD1, 0xB8,
0xC2} }

When I try to list the pins I get an error ... see code below

CComPtr <IBaseFilter> pHTCFilter;
hr = pHTCFilter.CoCreateInstance(CLSID_HTCCameraFilter);
hr=pFilterGraph->AddFilter( pHTCFilter, L"HTC Source" );

IPin * m_htc_out_Pin;
CComPtr<IEnumPins> pEnum;
hr = pHTCFilter->EnumPins(&pEnum);
hr = pEnum->Reset();
hr = pEnum->Next(1, &m_htc_out_Pin, NULL); <<< returns FALSE
PIN_INFO pinInfo;
hr = (m_htc_out_Pin)->QueryPinInfo( &pinInfo );

Thanks,
Kris

Before enumerate the pins, try to set properties fo this source filter (Im
talking about VCapName).
