Update:

* totem is fixed by the gst-plugins-bad fix released today.
* mpv is fixed by the patch proposed in bug 1708102.
* chromium needs to either be ported to native Wayland, or for libva to be 
enhanced with DRI3 support. There are no workarounds for Chromium other than to 
avoid Wayland and use Xorg sessions.
* gst-play-1.0 needs an enhancement to mutter linked above, but the workaround 
mentioned above is also simple.

** Changed in: mutter (Ubuntu)
   Importance: Medium => Low

** Changed in: chromium-browser (Ubuntu)
       Status: New => Confirmed

** No longer affects: totem (Ubuntu)

** No longer affects: intel-vaapi-driver (Ubuntu)

Bug description:
  The Intel i965 VA-API driver works well in Xorg sessions (Unity7 and
  Gnome Shell). But it refuses to load when in a Wayland session:

  $ totem bbb_sunflower_1080p_60fps_normal.mp4
  libva error: va_getDriverName() failed with unknown libva 
error,driver_name=(null)

  $ env LIBVA_DRIVER_NAME=i965 totem bbb_sunflower_1080p_60fps_normal.mp4
  totem: intel_driver.c:112: intel_driver_init: Assertion

  WORKAROUNDS:

   * Use weston instead of gnome-shell; or
   * $ env -uDISPLAY totem ... # but creates corruption -> bug 1701463
   * $ env GST_GL_WINDOW=wayland totem ... # but creates corruption -> bug 
1701463
   * $ env GST_GL_WINDOW=wayland gst-play-1.0 --videosink glimagesink ...
   * $ env -uDISPLAY mpv --hwdec --opengl-backend=wayland ...
