With both H264 and VP9 video. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1889784 Title: Hardware-accelerated video decoding (VA-API) broken in Firefox 79 (Wayland) Status in Mozilla Firefox: Fix Released Status in firefox package in Ubuntu: Triaged Bug description: After updating Firefox from 78 to 79, hardware-accelerated video decoding no longer works properly in Wayland: streaming video gets cut off with an error message from the service. == Steps to reproduce == 1. Follow the steps in [1] to enable VA-API. 2. Open a Youtube/Twitch video (for instance https://www.twitch.tv/rifftrax), press play == What I expect to happen == For the video be played without issues (as it did with Firefox 78). == What happens == After playing for a while (anything from just a few seconds to a couple of minutes), the video stops and is replaced by a service-specific error message, such as error #3000 (in case of Twitch). Even when playing, the video also flickers green. After reloading the tab, the video again plays for a few seconds before the error message reappears. == Other info == A fix is apparently already in the works upstream [2]. * [1] https://mastransky.wordpress.com/2020/06/03/firefox-on-fedora-finally-gets-va-api-on-wayland/ * [2] https://bugzilla.mozilla.org/show_bug.cgi?id=1645671 ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: firefox 79.0+build1-0ubuntu0.20.04.1 ProcVersionSignature: Ubuntu 5.4.0-42.46-generic 5.4.44 Uname: Linux 5.4.0-42-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.11-0ubuntu27.4 Architecture: amd64 BuildID: 20200720193547 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Fri Jul 31 17:07:50 2020 InstallationDate: Installed on 2016-10-13 (1387 days ago) InstallationMedia: Ubuntu-Server 16.04.1 LTS "Xenial Xerus" - Release amd64 (20160719) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=fi_FI.UTF-8 SHELL=/bin/bash SourcePackage: firefox UpgradeStatus: No upgrade log present (probably fresh install) modified.conffile..etc.apport.crashdb.conf: [modified] mtime.conffile..etc.apport.crashdb.conf: 2020-05-11T14:52:22.308877 To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1889784/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
