Syntax

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 Value

Returns E_UNEXPECTED by default implementation; the overriding member function should return one of the following values, or an HRESULT error value if the value could not be set.

Value

Description

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 iPosition parameter.

This base class returns an error because no media types are supported by default.

Derived classes should override this member function.
