I am developing a QT application. Application contains a number of screens.
I have implemented a video player in one of the screen. I am using QT gstreamer for rendering the video. I can navigate from one page to another without any flickering. 

But once I take the video player page, there is a flickering issue is coming in every other pages. This is the page hierarchy

        in video player page, 
                Window,
                       Vertical layout
                                  GStream Video object.


 After playing the video, I have stopped the video before going to another page.
If I  don't add the gstreamer video object to the vertical layout, it will render in a seperate window, since it is a widget.In that case when I navigate to another pages the flickering is not there. So my question is what I need to do for cleaning a gstreamer video object when we remove it from a parent.
