Ignore glsinkbin, it's just a wrapper. gtkglsink, gtksink, qmlglsink
are widget sink. They don't support GstVideoOverlay. Use glimagesink,
xvimagesink if you don't want to use a separate window for overlaying
your video. The widget based sink are design to be composed within your
widget tree. Instead of using the GstVideoOverlay interface, you get
the "widget" property on them, and add the widget to you UI the way it
works in your widget library.
