Broadwell vaapi video decode broken by i915_bpo migration
Status in linux package in Ubuntu:
Since upgrading from linux-image-3.19.0-28-generic to linux-
image-3.19.0-30-generic, vaapi-accelerated video playback on Kodi 15.2
(and 15.1) is now all black.
On-screen display items (eg. elapsed time) and audio still work, but
the decoded video content is now all black. Disabling vaapi
acceleration in the Kodi options restores the video playback.
I have bisected the problem to this commit:
The problem still happens in Ubuntu-3.19.0-31.36, as well as
Ubuntu-4.0.0-1.2 and Ubuntu-4.2.0-16.19 from the ubuntu-wily repo.
It appears that the above commit flicks the switch on many changes,
and doesn't really shed too much light on what the actual problem
I've tried moving that commit earlier into the history in the hope
that I might be able to find a 'good' point to bisect from, but had no
luck. The furthest I was able to push it back was
