Thanks for helping. Still not working.

I have replaced glimagesink by waylandsink. If I don't call 
"gst_video_overlay_set_window_handle", the video appears in the back. So 
at least, waylandsink is working. But note that the video is appearing 
without being part of any window at all.

If I call "gst_video_overlay_set_window_handle", the video doesn't 
appear and doesn't play. I also receive the following message:

waylandsink cannot use an externally-supplied surface without an 
externally-supplied display handle. Consider providing a display handle 
from your application with GstContext

Am I missing another API call?
