Hello,
Somehow i lost the first 3 options for Hardware Decoding and i don’t know why. All my options are still unchanged.

hello kobold,

yes ff made some weird changes that you’ll need to revert manually. i can’t find the topics in a minute but if you check the forum-search for “firefox acceleration” you’ll find a lot of them. check for the changes of “media.xxxx” that are reported in the topics.

Check about:config and revert your changes to the default values. Then, you could try enabling them one by one. Firefox changes something and doesn’t need most of the settings anymore.

Does it work in general? Does vainfo show you success?

What you mean with vainfo? when i type this in terminal: command not found.

5 
media.ffmpeg.encoder.enabled
media.ffmpeg.vaapi.enabled

are they set to true ?

6

I just switched media.ffmpeg.vaapi.enabled to true.

media.ffmpeg.encoder.enabled was already set to true

Still all unsupported under hardware support.

What are my default values? :smile:

7

You can reset them.

Cold it be that vdpau is not supported anymore and you need vaapi instead?
Did you follow the archwiki page? Firefox - ArchWiki

8

gstreamer-vaapi? All other packages are only AUR.

9

You need “libva-nvidia-driver”
Latest nvidia
media.ffmpeg.vaapi.enabled to “true”

and if you don’t have errors in logs when you start firefox in “about:support” you will see that you have hardware decoding in working order

10

This driver was installed already, it solved my problem 4 month ago… but its no longer working.

11

This is your problem:

libva-nvidia-driver requires nvidia-drm.modeset=1 in order to work

Good catch, i really forgot there was a relation between this both.

13

there is the package
“firefox-vaapi”

Thanks, but i think i trade this 2 error’s:

Mär 22 12:59:04 koboldx-z170 kernel: [drm:drm_new_set_master] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Failed to grab modeset ownership
Mär 22 12:59:04 koboldx-z170 kernel: [drm:drm_new_set_master] *ERROR* [nvidia-drm] [GPU ID 0x00000100] Failed to grab modeset ownership

Against the AUR package, i try to evade AUR as much as possible.

Codec Name Software Decoding Hardware Decoding
H264 Supported Supported
VP9 Supported Supported
VP8 Supported Supported

right now with nvidia-drm.modeset=1 in grub
