Hi. Trying VAAPI/X11 on Nightly 81.0a1/20200807213618, `intel_gpu_top` confirms HW acceleration is active, but ***all videos appears constantly green, for the whole duration of the video (not just for a moment or a few frames)*** . Is there already a bug for it, or should I file one?
- `MOZ_X11_EGL=1` - `media.ffmpeg.dmabuf-textures.enabled:true` , `media.ffmpeg.vaapi.enabled:true` , `media.ffvpx.enabled:false` - enhanced-h264ify forcing H264 - Arch, latest linux / xorg / intel drivers. Problem reproducible with both i965 and iHD drivers. If already answered, sorry for the noise. If not, please tell me what debug info you'd like me to share in a new bug. -- 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
