Example

Here is example of how to set standard format to the playlist:

Dim myPlaylist As New MPlaylistClass()
Dim vidProps As New M_VID_PROPS()
Dim strFormat As String
Dim nCount As Integer
myPlaylist.FormatVideoGetCount(nCount)
myPlaylist.FormatVideoGetByIndex(eMFormatType.eMFT_Convert, nCount - 1, vidProps, strFormat)
myPlaylist.FormatVideoSet(eMFormatType.eMFT_Convert, vidProps)
MPlaylistClass myPlaylist = new MPlaylistClass();
M_VID_PROPS vidProps = new M_VID_PROPS();
string strFormat;
int nCount;
myPlaylist.FormatVideoGetCount(out nCount);
myPlaylist.FormatVideoGetByIndex(eMFormatType.eMFT_Convert, nCount - 1, out vidProps, out strFormat);
myPlaylist.FormatVideoSet(eMFormatType.eMFT_Convert, ref vidProps);
var
myPlaylist: MPlaylist;
myFormat: IMFormat;
nCount: integer;
vidProps: M_VID_PROPS;
strFormat: string;
begin
myPlaylist:= CreateComObject(CLASS_MPlaylist) as MPlaylist;
myFormat := myPlaylist as IMFormat;
myFormat.FormatVideoGetCount(nCount);
myFormat.FormatVideoGetByIndex(eMFT_Convert, nCount-2, vidProps, strFormat);
myFormat.FormatVideoSet(eMFT_Convert, vidProps);
end;
