Can you describe the prior steps you have taken to ensure GStreamer
will find your wayland display ? On Fedora I would have to do:

  export WAYLAND_DISPLAY=/run/user/1000/wayland-0
  gst-launch-1.0 videotestsrc ! glimagesink

waylandsink does not work due to a bug in mutter compositor. The spec
says that we must wait for a configure-even prior to attaching a
buffer, but mutter in that specific context ends up waiting for an
attachement to send the event. We have merged a workaround in master
and will backport to 1.16.1.
