if your xvideo support colorkeying, you can ask xvimagesink to not
manage the colorkey and do it yourself, you could then use e.g. the
whole window or any subreagio for the video (the the gdk-window for
that) and have regular buttons above the video. You would need to handle
expose events on the gtk-widget that provides the video window and in
the expose handler paint it with the colorkey. This is how we get
buttons to hover over the video/camera on Nokia N900. No fancy OpenGL :)
