If we create use gtk to create a window and use
to set window id  to d3dvideosink. The video is played but the looks alpha
blended with background window.
Is this a gstreamer problem or gtk problem? 

If I use glimagesink the problem is solved but the glimagesink is not
resized when the window resizing.
