Sounds like we have a semi-permanent workaround now:
gstreamer-vaapi (1.16.0-3ubuntu2) eoan; urgency=medium
* debian/patches/git_no_amd.patch:
- backport an upstream change to disable vaapi with the amd drivers,
the current experience is buggy and it's better to just not enable it

Title:
[radeon] Totem with gstreamer1.0-vaapi and Wayland is just a black
screen, then crashes.
Status in gstreamer-vaapi package in Ubuntu:
Confirmed
Status in mesa package in Ubuntu:
Confirmed
Bug description:
WORKAROUNDS
Just for totem: sudo apt remove gstreamer1.0-vaapi
Or to workaround in all players: sudo apt remove mesa-va-drivers
ORIGINAL DESCRIPTION
Totem with gstreamer1.0-vaapi and Wayland crashes on my machine with
AMD Fury graphics card and open source drivers. Video output is just a
black frame and crash happens within just a few seconds after video
playback starts.
Could not reproduce bug on two older Intel laptops with iGPU's where
hardware acceleration seemed to work fine under Wayland.
Issue is only present on Wayland, not x.
I can get hardware accelerated video playback working on Wayland with
'mpv --hwdec=vaapi-copy --opengl-backend=wayland' but this is the only
way I have found so far. Even in mpv, no other option than vaapi-copy
works.
gst-play-1.0 outputs the following error:
ERROR Internal error: could not render surface for file:///***
ERROR debug information: ../../../gst/vaapi/gstvaapisink.c(1483):

Description: Ubuntu Artful Aardvark (development branch)
Release: 17.10
totem 3.25.90.1-0ubuntu3
gstreamer1.0-vaapi:amd64 1.12.3-1ubuntu1
