HW Transcoding RK3588 arch not working - Crashdummy - 2025-03-08

Hi there
I am currently struggling to get hardware transcoding working on arch and I've got not idea why.
I've followed this guide ( https://jellyfin.org/docs/general/administration/hardware-acceleration/rockchip/ ) but there are a few things I dont get.
When I run the verification I get errors.

Code:
$ sudo /usr/lib/jellyfin-ffmpeg/ffmpeg -v debug -init_hw_device rkmpp=rk -init_hw_device opencl=ocl@rk

It looks like the the jellyfin-ffmpeg is missing
Code:
--enable-rkmpp
.
The
Code:
ffmpeg-mpp-git
has this enabled but it still throws errors.

Code:
$ sudo ffmpeg -v debug -init_hw_device rkmpp=rk -init_hw_device opencl=ocl@rk

Regarding the libmali opencl The note mentions
> Only needed before using HDR tone-mapping on RK3588/3588S. This is done to ensure that the user space firmware and kernel driver versions match, otherwise OpenCL will not work properly.

Wouldnt that mean I can ignore this ?
It doesnt look like its actually working because when I monitor the load using
Code:
$ sudo watch -n 1 cat /sys/kernel/debug/rkrga/load

It always remains at 0 load

Code:
num of scheduler = 3
================= load ==================
scheduler[0]: rga3
load = 0%
-----------------------------------
scheduler[1]: rga3
load = 0%
-----------------------------------
scheduler[2]: rga2
load = 0%
-----------------------------------

Am I forgetting anything ?
My System is a Radxa Rocks 5b+ and i used the community arch installer.
https://github.com/kwankiu/archlinux-installer

Code:
OS: Arch Linux ARM aarch64
Host: Radxa ROCK 5B Plus
Kernel: Linux 6.1.75-rockchip-g7725578fd0ae-dirty
CPU: rk3588 (8) @ 2.30 GHz
GPU: Rockchip rk3588-mali [Integrated]
Memory: 2.10 GiB / 31.04 GiB (7%)
