[Ubuntu-x-swat] [Bug 1698287] Re: VA-API fails to initialize in a Gnome Shell Wayland session

[Daniel van Vugt]

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)

I am going to work on additional patches so that by the time 17.10 is
released all you will need is:

   mpv myvideo.mp4

  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:

[Ubuntu-x-swat] [Bug 1698287] Re: VA-API fails to initialize in a Gnome Shell Wayland session

[Daniel van Vugt]

Doug,

A couple of my fixes have landed today, as well as ffmpeg 3.3 which
fixes most of mpv's acceleration problems. However your comment reminds
me there's another bug with mpv I need to open and fix... mpv will by
default try to use the X11 display provided by Xwayland and ends up with
vaapi-copy. You can work around that trivially and get hwdec=vaapi
proper working again by hiding Xwayland:

   env -uDISPLAY mpv --hwdec myvideo.mp4

This bug was fixed in the package gst-plugins-bad1.0 - 1.12.2-1ubuntu2

gst-plugins-bad1.0 (1.12.2-1ubuntu2) artful; urgency=medium

[Doug McMahon]

Regarding the mpv in artful:
You can currently get some vaapi support in wayland session, you'd need to use
hwdec=vaapi-copy
Not as effective as hwdec=vaapi but I don't think they'll be changing that 
(commit noted), in near future.

vaapi in mpv in a wayland session was broken due to this commit

More progress: gst-play-1.0 fails on Gnome Shell Wayland only (and not
in Weston) because of a mutter problem (or arguably the gstreamer-vaapi

On second thoughts, if we keep this bug about decoding flaws, and deal
with all the display flaws elsewhere then we might be able to close some
tasks here...

[Ubuntu-x-swat] [Bug 1698287] Re: VA-API fails to initialize in a Gnome Shell Wayland session

[Daniel van Vugt]

Without sounding too defeated, I think it might be a good idea for us to
not use the patch in comment #5 any time soon. The reason is that while
the patch is correct, it triggers bigger issues in clutter-gst. And that
starts to make me think I'm going too deep down this rabbit hole.

It probably doesn't make sense to fix gstreamer/clutter stuff if it's
too time consuming, when we already know gstreamer lacks a variety of
working demuxers, and is already so unpopular that it's not part of the
long term plan anyway (https://wiki.ubuntu.com/IntelQuickSyncVideo).

The only real problem is that 'totem' is still our default video player.
And if clutter-gst is a mandatory requirement for that then I either
need to not give up yet, or we should consider changing default video
players in future (ideally to something that's more purely FFmpeg
instead of GStreamer).
