Comment (by cypherpunks):

 Patch for BaseFilter:
 {{{
      return E_POINTER;
    }

 -  if (riid == IID_IBaseFilter || riid == IID_IUnknown) {
 +  if (riid == IID_IBaseFilter || riid == IID_IUnknown ||
 +      riid == __uuidof(BaseFilter)) {
      *aInterface = static_cast<IBaseFilter*>(this);
    } else if (riid == IID_IMediaFilter) {
      *aInterface = static_cast<IMediaFilter*>(this);
 }}}
 and for BasePin:
 {{{
      return E_POINTER;
    }

 -  if (aIID == IID_IPin || aIID == IID_IUnknown) {
 +  if (aIID == IID_IPin || aIID == IID_IUnknown ||
 +      aIID == __uuidof(BasePin)) {
      *aInterface = static_cast<IPin*>(this);
    } else if (aIID == IID_IQualityControl) {
      *aInterface = static_cast<IQualityControl*>(this);
 }}}
 Probably non working/wrong, and for sure incomplete. Yet another
 QueryInterfaces waiting for some patching too.
