HRESULT EnumMediaTypes( IEnumMediaTypes ** ppEnum );
Parameters
- ppEnum
- Pointer to an enumerator for the media types.

Remarks
This member function implements the IPin::EnumMediaTypesmethod. It returns an enumerator object implemented by the CEnumMediaTypesclass and obtains the IEnumMediaTypesinterface, which adds a reference count to this enumerator. If an application receives an enumerator, the application must release this when done with it by calling IUnknown::Releaseon the enumerator.
