Hardware video acceleration doen`t work even after all setup

I have TECNO Megabook K16S AMD laptop running Arch Linux
It has a amd CPU and an amd GPU, I did everything as it says on the wiki and it still doesn't work.
I've checked several browsers and distributions, but it doesn't work anywhere, even on Ubuntu.
But everything works fine on Windows, without missing frames.
I checked extra/chromium and it says that Hardware video acceleration is working (chrome://gpu) but it isn`t in reality
I am using KDE Plasma Wayland
All latest updates are installed and amd-ucode too
Also i tried compiling firefox-vaapi from AUR but it didn`t work
Laptop specs: AMD Ryzen 5 5625U with Vega 7 GPU (512MB VRAM), 32 GB RAM
Kernel: Linux 6.12.10-arch1-1
I have mesa 1:24.3.4-1 installed

If you carefully read the wiki you'd know there is a dedicated thread on how to enable hardware video acceleration in Chromium

And enabling it in Firefox is pretty straightforward: https://wiki.archlinux.org/title/Firefo … celeration

There is a small amount of dropped frames even with hardware acceleration enabled. My Firefox gets like 3-5 drops per 1000 frames.

Check DEC/ENC % in nvtop. If it shows a value > 0 then hardware acceleration works

Yeah it shows 20-40% of decoder usage(I never knew that nvtop could show encoder and decoder usage), but it can be 50+ dropped frames per second sometimes and this is the problem

512MB VRAM might be the source of the problem. Can you increase it to 4Gb at least?

I'll try as soon as I get the chance
