Returns the media type for the output pin to use.
HRESULT GetMediaType( int iPosition , CMediaType * pMediaType );
Parameters
- iPosition
- Position of the media type in the media type list.
- pMediaType
- Returned media type object.
Return Values
Returns an HRESULTvalue that depends on the implementation of the pure virtual CTransformFilter::GetMediaTypemember function. HRESULTcan include one of the following constants.
NOERROR A media type is returned. S_FALSE Although the iPositionparameter typically is valid, it does not correspond to a media type that is currently valid. VFW_S_NO_MORE_ITEMS The iPositionparameter is beyond the valid range. Use other standard error values, such as E_INVALIDARG, for error cases.
Remarks
This member function overrides the CBasePin::GetMediaTypemember function and calls the pure virtual CTransformFilter::GetMediaTypemember function, which must be overridden to return media types supported by your filter. This is part of the implementation of CBasePin::EnumMediaTypes.
