Firefox 85 Green Video Playback
Hello Firefox Forum,
I get green videos when using hardware acceleration. intel_gpu_top shows decoding action when I start firefox with: MOZ_WAYLAND_DRM_DEVICE=/dev/dri/renderD129 LIBVA_DRIVER_NAME=i965 MOZ_X11_EGL=1 MOZ_WEBRENDER=1 firefox
There's only 3 lines of error in the console, so I don't think it's related:
(firefox:12623): GLib-GIO-WARNING **: 22:01:35.112: /etc/xdg/kde-mimeapps.list contains a [Added Associations] group, but it is not permitted here. Only the non-desktop-specific mimeapps.list file may add or remove associations.

Can anyone help me identify the issue? I would really like to use the hw acceleration.
With best regards LuxidEx

Please provide steps to replicate and provide links to the video(s). Are you using KDE or Gnome? Make sure you have the latest FFmpeg and libavcodec packages are updated. see screenshot
Can you download a separate version of Firefox to a folder and run it from there to test? https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

It seems to affect all videos, I will try your suggestions and response back.
Thank you for your answer. I am using KDE.
Edit: I tried running firefox seperately downloaded into /tmp/ with:
MOZ_WAYLAND_DRM_DEVICE=/dev/dri/renderD129 LIBVA_DRIVER_NAME=i965 MOZ_X11_EGL=1 MOZ_WEBRENDER=1 ./firefox
Then I edited: about:config
media.ffmpeg.vaapi.enabled = true
restarted and that's everything I need to get the green playback.
I have installed ffmpeg version n4.3.1 Copyright (c) 2000-2020 the FFmpeg developers built with gcc 10.2.0 (GCC)
and this ffmpeg seems to bring along the libav packages.
Best Regards

My media.ffmpeg.vaapi.enabled was false, changed it to true and no issues. I'm running Nightly.
