The documentation for video acceleration continues to evolve day-to-day
as we learn where the bugs are, and errata in external documentation. So

Hi all,
Here's an update from this week:
= GNOME =
We’ve migrated ubuntu-session to a new unity-session package. This
means that the default session is GNOME Shell and people can install
Unity 7 and it’s related packages via unity-session. The migration is
working well so far, but we still have some more work to do in order to
make sure everything “just works”.
= LivePatch =
We’re now working on the update-manager UI to add the list of kernel
CVEs which are handled by the LivePatch service and a brief description
of each.
= Snaps =
We’ve done more work on getting desktop themes working better with
Snaps. We’re documenting the problems we’ve encountered and are
creating some sample Snaps help with making the improvements we need.
= QA =
We completed our review of the desktop test plan this week and have set
our priorities for this cycle. This will cover installation, upgrades,
some core application smoke tests, suspend/resume, Network Manager and
translations. We will be publishing a blog on how you can get involved
next week.
= Updates =
A new version of PulseAudio is in Xenial proposed (version
1:8.0-0ubuntu3.3). This brings fixes for Bluetooth A2DP audio devices.
We’d appreciate testing and feedback.
https://launchpad.net/ubuntu/+source/pulseaudio/1:8.0-0ubuntu3.3
Updated chromium beta to 60.0.3112.32, dev to 61.0.3128.3.
= Video Acceleration =
We’ve got hardware accelerated video decoding working in a
Proof-Of-Concept using a GStreamer and VA-API pipeline. The result is
3% CPU usage to play an h264 4K 60FPS video on Haswell. 4K h265 HEVC is
also playable but requires a Skylake or later processor. This wiki
page has been updated with information about how to try it yourself:
