I can confirm this bug exists. OS version: Ubuntu 18.04 beta rc Hardware: Intel core i5 7400 (Kaby lake processor) with Intel HD graphics 630 supporting VP9 10-bit and 8-bit video decoding.
In version 1.8.x of the driver the VP9 decoding is broken, the corresponding upstream patch got into 2.0.0. But since VP9 profiles are missing in 2.0.0 driver in Ubuntu, hardware acceleration is absent, so high cpu and power usage. The buggy driver 1.8.x is used in the vlc snap too and snap developers doubt the driver version in snap will be upgraded. * VP9 decoding broken in 17.10 * VP9 decoding broken in snap packages * VP9 decoding broken in 18.04 beta rc Either driver version has to be updated to 2.1.0 or at-least cherry pick a one line patch to current Ubuntu core snap, a link for which I will mention below. Upstream driver patch: https://github.com/intel/intel-vaapi- driver/commit/9d66570032fb02b1e79a883af7697b035d700a8e Upstream bug report: https://github.com/intel/intel-vaapi- driver/issues/297 In any way kindly support VP9 hardware decoding via supported Intel hardwares in 18.04 or in 17.10(by backporting/cherry picking) or atleast via updated snap core/apps. ** Bug watch added: github.com/intel/intel-vaapi-driver/issues #297 https://github.com/intel/intel-vaapi-driver/issues/297 -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to intel-vaapi-driver in Ubuntu. https://bugs.launchpad.net/bugs/1756380 Title: vaapi VP9 hardware decoding not working anymore in bionic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/intel-vaapi-driver/+bug/1756380/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
