Please describe the problem:
When you stop directdrawsink and start, directdrawsink can't create a new window.
In gst_directdraw_sink_cleanup function of gstdirectdrawsink.c, there is this code :
/* Post quit message and wait for our event window thread */
  if (ddrawsink->video_window && ddrawsink->our_video_window)
    PostMessage (ddrawsink->video_window, WM_QUIT, 0, 0);

But I think it should be this :

/* Post quit message and wait for our event window thread */
  if (ddrawsink->video_window && ddrawsink->our_video_window)
  {
    PostMessage (ddrawsink->video_window, WM_QUIT, 0, 0);
    ddrawsink->video_window = NULL;
  }
