Hardware accel doesn't work on Tiger Lake

Running Tiger Lake integrated graphics on my laptop (Thinkpad X1 Carbon G9), and with the latest Mesa and Intel firmware packages, hardware video acceleration appears to be not working. When using YouTube (Firefox claims hardware decoding as possible for all codecs in :support), my power usage reported via Powertop shoots up to 15-20w.
MPV with the -hw-dec option reports:

[ffmpeg/video] vp9: Device does not support the VK_KHR_video_decode_queue extension!
[ffmpeg/video] vp9: Failed to initialize decoder for 1920x1080 @ 0
[ffmpeg/video] vp9: Not all references are available
[ffmpeg/video] vp9: Not all references are available

MPV version outputs:

mpv v0.41.0 Copyright © 2000-2025 mpv/MPlayer/mplayer2 projects
 built on Dec 22 2025 14:58:51
libplacebo version: v7.351.0
FFmpeg version: n8.0.1
FFmpeg library versions:

   libavutil       60.8.100
   libswresample   6.1.100
   libswscale      9.1.100

Thanks for any help.

PS. sorry for the initally bogus forum post, I've got a cat around the house and he decided to walk around on my keyboard and press enter to submit a mess of gibberish.

nb. that HW acceleration in browsers is a mess of its own, focus on mpv for the start.

Additionally, I used the software Handbrake to transcode the test video I used for the earlier post into H.264, and it outputs an identical error message (though, with H.264 in place of VP9.)
I installed the vpl_gpu_rt package, and tried both videos, and still nothing changed.

I also tried the opt-in-with-kernel-parameters Xe driver from the latest kernel and no dice.

Re: Hardware accel doesn't work on Tiger Lake

mpv --vo=gpu --hwdec=vaapi video.mp4

Is this on wayland or x11?
From the previous output

vulkan.info --summary

with the latest Mesa and Intel firmware packages

For clarification, is this a regression? Does downgrading either or both of them fix this?

I tried bumping Mesa down to 1.24-3.3.2, and it appears to have broken my graphics; I didn't want to bother any further scaling down the dependency tree to find out what package to downgrade to fix that.

You, must have touched the dot - sorry.

Humm?
Nothing seems really rebuild for the mesa update?

So what's the output for

mpv --vo=gpu --hwdec=vaapi video.mp4

?

Ah, my apologies, appear to have missed that in the reply.
It appears to be working fine, and my power usage appears to be normal for hardware decoding (10-11W; or at least, I think that's normal. I don't have a frame of reference for power usage :^) )

 ● Video  --vid=1               (vp9 1920x1080 29.97 fps) [default]
● Audio  --aid=1  --alang=eng  (opus 2ch 48000 Hz) [default]
MESA-INTEL: warning: ../mesa-25.3.4/src/intel/vulkan/anv_formats.c:993: FINISHME: support more multi-planar formats with DRM modifiers
Using hardware decoding (vaapi).
AO: [pipewire] 48000Hz stereo 2ch floatp

AV: 00:00:01 / 00:26:50 (0%) A-V: -0.000
Exiting... (Quit) 

This is quite strange, I'm curious what's preventing Firefox from invoking hardware acceleration, then?

Is this an optimus system (hybrid graphics)?

Re: Hardware accel doesn't work on Tiger Lake

https://wiki.archlinux.org/title/Firefo … celeration

I've tried everything in this wiki page already. Even after setting the verbose logging enviroment variable and playing a video, the terminal is still blank. I even tried using logging to a file with all logging modules enabled, and the log files were also still blank.

Is this an optimus system (hybrid graphics)?

No, the only GPU present in this system is the integrated one.

I tried this plugin, along with a fork of it and neither seemed to have any impact on the power use. Perhaps a full reinstall is in order?

Re: Hardware accel doesn't work on Tiger Lake

Reinstalling the same software will lead to the same results - this isn't windows. You'd have a better chance wiping your FF profile or testing a fresh user.

However, afaiu your problems are limited to the browser (firefox) and don't exist w/ eg. mpv
Does using h264ify get you h264 videos (eg. youtube exposes this in a rightclick menu "stats for nerds")

impact on the power use

Errr… power use?
Check intel_gpu_top, https://wiki.archlinux.org/title/Hardwa … rification
The "power use" of youtube.com (in case that's your testcase) is mostly down to the social media crap and AI and javascript, not the video playback.

Re: Hardware accel doesn't work on Tiger Lake

.

The whole reason I was tipped off to the existence of this problem is because YouTube uses almost 20w of power and that's just not sustainable on a laptop; I would be fine with any sort of hacky solution if it just brings my power down.

Re: Hardware accel doesn't work on Tiger Lake

Appears yes: https://en.wikipedia.org/wiki/Advanced_Video_Coding

Check intel_gpu_top to see whether the browser uses VAAPI, maybe also try chromium resp. Vivaldi has its own ffmpeg implementation
https://wiki.archlinux.org/title/Vivaldi#Media_playback

But there's also countless solutions to watch youtube w/o a browser (I basically never open the webpage) or things like https://yewtu.be

Still no dice; the Video category is empty. https://imgur.com/NuU4Ve4

Re: Hardware accel doesn't work on Tiger Lake

This dice: https://firefox-source-docs.mozilla.org … dd-process
There's one bar (enforcing VP9 or higher resolution/refresh rate might change that?)

Test yewtu.be or some local video in the browser's media player to see whether the problem is actually video decoding or youtube.

You'd think that decoding a video at 1080p60 would use more than 2% GPU, no? And the 25% usgae of Firefox for 3d seems kind of suspect...

On a local video, the power draw of my laptop (which is what I'm using as a sort of hacky-test to see if video playback is working as it should) stays around 10-11W, which as per MPV seems standard.
Yewtu.be seems to be broken for me, all videos report unable to play because of server error or unsupported format.
So I suppose the problem is with YouTube then?

Re: Hardware accel doesn't work on Tiger Lake

You'd think that decoding a video at 1080p60 would use more than 2% GPU, no?

Depends on the video, decoding 4k @ 60fps takes no CPU if the movie is a pre-sfx marvel movie (ie. a green screen) - also there's gonna be only action while the movie is actually decoded (what can fluctuate w/ buffers and is gonna be nothing when hitting pause)

Yewtu.be seems to be broken for me

Download some youtube video w/ yt-dlp  (-F for available formats, make it h264) and open the local file in the browser and see how that performs.
