I've done all the things told me above, but the Gstreamer overlay 
continue to use all the window, not just the portion of the frame 
associated. I noticed that the function get_window() return the main 
window ID, so I think that is natural that Gstreamer occupies all the 
window. Is there some way to set a "subwindow" to a Gtk::Frame?
Moreover, I found this page 
http://www.gstreamer.net/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gstxoverlay.html#gst-x-overlay-set-render-rectangle 
but in the last distribution of winbuild this function is not available 
yet. There is a way around to obtain the same result. I know that is not 
the right mailing list to ask this but maybe someone can reply.
Thanks
