Call setUpdatesEnabled(false) on the widget, and pass the window ID to 
the video sink with:

   // Create pipeline.
   // ...
   widget->setUpdatesEnabled(false);
   gst_video_overlay_set_window_handle(GST_VIDEO_OVERLAY(pipeline),
                                       (guintptr)widget->winId());

When you start the pipeline, output will be going to the Qt widget.

Alternatively, you can use gstreamer through QtGStreamer, which handles 
these things automatically (and gives you a C++ API for GStreamer.)
