Hi,

The trend with recent GUI toolkit frameworks is to perform rendering
entirely client side and avoid actual windows (X11, wayland, or
otherwise).  This of course does not fit very well with GstVideoOverlay
and as a result, a number of sinks have been implemented for various
toolkits.  For Qt there is currently only a qmlglsink that will draw
into a qml based scene but no Qt Widget based element (yet!).  The
element has not been tested on the rpi however there would only need to
be a couple of changes in the element at most to make it work there as
well.  I currently don't have my rpi with me to be able to check if it
works or not.

Cheers
-Matt
