CTransInPlaceOutputPin::EnumMediaTypes (Compact 2013)

  • [アーティクル]

3/26/2014

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.
