Sorry. I need to rephrase on my sentence. What I mean the video still stuck on
the desktop. It like video output surface didn't get clean up. Command pipeline
still not exit, ever I keep press the space button. I can see the process id in
"ps-aux | grep gst-launch-1.0".

When crashed happen, the video output will be stuck on the screen forever. If
didn't crash, I press ctrl-c after video stream finish the video output will
disappear. But I can't confirm the gst_vaapi_surface_destroy got call or not if
I did that. I need to dump some print message to check on it. 

Right behaviour should be same as waylandsink after videos finish playback, it
should be exit.

Any information that miss out you need, i will provide. Glab you able to
reproduce the issue on your side.
