Is there a possibility to retrieve a CKsAudCapFilter* (instead of a
IBaseFilter) filter object using this implementation:
IBaseFilter* pFilter;
pMoniker->BindToObject(NULL, NULL, IID_IBaseFilter, (void**)&pFilter);
What IID is responsible for getting such a filter object? I would like to
enum the CKsAudCapFilter devices to chose one and then pass it to the KS
pFilter->CreateCapturePin(...) function to get a capture pin. Or does
anybody know another way of getting the names (manufacturer, device name,..)
of CKsAudCapFilter or CKsAudRenFilter objects?
Many thanks!
Patrick

There is no guarantee that it CAN be "got". You can fetch the friendly
name, but if the designer chose to name the device "Anonymous Atomic
X-Blaster", that's about as far as you can go.
You can fetch the FriendlyName from the property bag when you enumerate
the devices to create your graph. Search for "ipropertybag enumerate"
to find a code example.
