Delphi

Dim nIndex As Integer
Dim strFormat As String
Dim vidProps As M_VID_PROPS
Dim myPlaylist As New MPlaylistClass()
myPlaylist.FormatVideoGet(eMFormatType.eMFT_Output, vidProps, nIndex, strFormat)
vidProps.eScaleType = eMScaleType.eMST_LetterBox
myPlaylist.FormatVideoSet(eMFormatType.eMFT_Convert, vidProps)

int nIndex;
string strFormat;
M_VID_PROPS vidProps;
MPlaylistClass myPlaylist = new MPlaylistClass();
myPlaylist.FormatVideoGet(eMFormatType.eMFT_Output, out vidProps, out nIndex, out strFormat);
vidProps.eScaleType = eMScaleType.eMST_LetterBox;
myPlaylist.FormatVideoSet(eMFormatType.eMFT_Convert, ref vidProps);

var
m_objPlaylist;;
m_pFormat;
vidProps: M_VID_PROPS;
strFormat: string;
nIndex: integer;
begin
m_objPlaylist:= CreateComObject(CLASS_MPlaylist) as MPlaylist;
m_pFormat := m_objPlaylist as IMFormat;
m_pFormat.FormatVideoGet(eMFT_Output, vidProps, nIndex, strFormat);
vidProps.eScaleType = eMScaleType.eMST_LetterBox;
m_pFormat.FormatVideoSet(eMFT_Convert, vidProps);
