Определить, когда TMediaPlayer закончил проигрывание

procedure TForm1.FormCreate(Sender: TObject);
begin
  MediaPlayer1.Notify   := True;
  MediaPlayer1.OnNotify := NotifyProc;
end;

procedure TForm1.NotifyProc(Sender: TObject);
begin
  with Sender as TMediaPlayer do
   begin
    case Mode of
      mpStopped: {do something here};
    end;
    //must set to true to enable next-time notification 
   Notify := True;
  end;
end;


{ 
  NOTE that the Notify property resets back to False when a 
  notify event is triggered, so inorder for you to recieve 
  further notify events, you have to set it back to True as in the code. 
  for the MODES available, see the helpfile for MediaPlayer.Mode;
