How to install OpenCL on OrangePi 5 Plus

[Lele]

I want to install jellyfin on my OrangePi 5 Plus and need OpenCL to enable HDR-SDR mapping.

I tried to follow the instruction on Jellyfin's official website: Rockchip VPU | Jellyfin

However, I'm stucked on the step of installing OpenCL.

I also tried this: Install OpenCL on Debian and Ubuntu and Armbian for Orange Pi 5 RK3588

But no luck either.

Both instruction led to broken hardware acceleration in chrome and failing to start kernal in Jellyfin.

 

Logs from ffmpeg:

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

Applying option init_hw_device (initialise hardware device) with argument opencl=ocl@rk.

Logs from Jellyfin:

Logs from clinfo:

I want to know how to correctly enable OpenCL on OrangePi 5 Plus, thank you!

Please let the community know which core your device is running on.

Please let the community know which core your device is running on.

Maybe it's this?

> uname -r
6.1.75-vendor-rk35xx

I'm using this img: Armbian_24.11.2_Orangepi5-plus_noble_vendor_6.1.75_gnome-kisak_desktop.img

After installed, I used armbian-config to disable the firmware update (because otherwise apt upgrade also break hardware acceleration in chrome). Then I ran:

sudo apt update
sudo apt upgrade

Then, following jellyfin's guide (Rockchip VPU | Jellyfin), in /etc/udev/rules.d/99-rk-device-permissions.rules, I also changed this:

KERNEL=="system", MODE="0660", GROUP="video"

to this:

KERNEL=="system", MODE="0666", GROUP="video"

I also paste the whole clinfo message here: pastebin (clinfo)
