virtual HRESULT GetMediaType( int iPosition , const CMediaType * pMediaType );
Parameters
- iPosition
- Position in the media type list.
- pMediaType
- Returned pointer to the media type at this position.
Return Values
Returns E_UNEXPECTED by default implementation; the overriding member function should return one of the following values, or an HRESULTerror value if the value could not be set.
S_FALSE Media type exists but is not currently usable. S_OK Media type was set. VFW_S_NO_MORE_ITEMS End of the list of media types has been reached. Remarks
This is a virtual member function that returns a media type corresponding to the position in the list specified by the iPositionparameter. This base class simply returns an error because no media types are supported by default. Derived classes should override this member function.
