I just noticed none of the 3 browsers I have installed (F, brave, vivaldi) are actually using hardware decoder for youtube videos, I have a laptop with a ryzen 4500u and when I play any 720p video on youtube, all the cores’ utilization jumps up to ~22% from what I can tell, none of the methods I tried (enabling flags and stuff : [HowTo] Enable Hardware Video Acceleration / Video Decode In Google Chrome, Brave, Vivaldi And Opera Browsers )
then I read a more concerning reply from a user on reddit, https://www.reddit.com/r/debian/comments/17khtrk/no_hardware_acceleration_of_videos_amd_ryzen_7/?rdt=41398
is this true? are there any workarounds?
hi, i followed the instructions on the nonfree.eu site, these to be more specific…
Install
Remove deprecated signatures
sudo rm -f /var/lib/pacman/sync/mesa-nonfree.*.sig
Locally trust CI key
sudo pacman-key --recv-keys B728DB23B92CB01B && \
sudo pacman-key --lsign-key B728DB23B92CB01B
Switch to Manjaro unstable branch and
sudo pacman-mirrors -aS unstable && \
sudo pacman -Syu
Download repo configuration
sudo sh -c "curl -s https://nonfree.eu/unstable/ > /etc/pacman.d/mesa-nonfree.pre.repo.conf"
Inject repo configuration in pacman.conf
The config must precede the core repo to work
sudo sed -i '/^\[core\]/i \Include = /etc/pacman.d/mesa-nonfree.pre.repo.conf\n' /etc/pacman.conf
then a Syyu
and rebooted, do I need to do anything else?
youtube still doesn’t seem to be using the hardware decoder…

The Ryzen 4500u may not support YouTube’s AV1 video format hardware decoding (my Ryzen 7 5800h, which is more recent, doesn’t).
So, to play YouTube videos with the hardware decoder you might want to go to your YouTube account settings Playback and performance section & change the AV1 settings to “Prefer AV1 for SD”.
Videos up to 480p will then use AV1 (software decode) for playback & higher resolutions will use VP9 (which should be hardware decoded as long as you have configured Firefox correctly).
When playing a YouTube video, you can also right-click on the video & select “Stats for nerds” to see which video & audio codecs the video is using:

to piggy-back on @scotty65 ’s suggestion…
For those who do not have an account, or need finer control there are addons like enhanced-h264ify, which despite its name actually allows control over a number of formats, ie for me (because I cannot use av01);

I’m not sure that’s the case, when I switched to windows 11(dualboot) videos on edge seems to use a decoder called D3D11… sorry if I’m being dumb…

d3-d11 is Direct3D 11, a part of DirectX.
By default on linux youtube will probably be trying to play AV1 - Wikipedia for hardware acceleration… but only so many (newer) GPUs support it. So there may be reasons to configure which format youtube serves.
We dont really care what windoze does … the question is what is available to you on linux.
This will depend on your hardware.inxi -Fazy and I might be able to tell you step-by-step.
EDITryzen 4500u. If thats accurate then I am pretty sure you dont have accelerated av1, so the above suggestions to disable it might make sense.

acceleration for vp9 seems to work on firefox, tested at 4k(CPU utilisation ~ 18%), but not on the chromium based browsers…

ok, i thought both windows and linux used the same hardware decoders

This confirms VP9 as your probably preferred format.https://chromewebstore.google.com/detail/enhanced-h264ify/omkfmpieigblcllmkgbflkikinpkodlk )
And if its working for FF … then chrom* is probably just a matter of the correct flags.

that’s probably it… do you know what flags to use? The guide seems to have been depreciated… i tried using
--enable-features=VaapiVideoEncoder,VaapiVideoDecodeLinuxGL --enable-gpu
also, in vivaldi://gpu decode is listed as enabled, yet yt doesn’t use it? here’s part of vivaldi://gpu I couldn’t understand much of it
