CTransInPlaceOutputPin::EnumMediaTypes (Windows Embedded CE 6.0)
1/6/2010
Provides a media type enumerator from the upstream filter.
Syntax
HRESULT EnumMediaTypes(
IEnumMediaTypes** ppEnum
);
Parameters
- ppEnum
Pointer to an enumerator for the media types.
Return Value
Returns NOERROR if successful, VFW_E_NOT_CONNECTED if there is no connection, or an HRESULT that indicates an error with the enumerator, such as E_POINTER or E_OUTOFMEMORY.
Remarks
This member function overrides the CBasePin::EnumMediaTypes member function and implements the IPin::EnumMediaTypes method.
Transform-inplace filters use the media type enumerator from adjacent filters because they do not change the media type.
This member function calls IPin::EnumMediaTypes on the output pin connected to the filter's input pin.
If an application receives an enumerator, the application must release it when finished.
