Creating a bug report/issue

I have searched the existing open and closed issues

Required Information

  • DietPi version | Core:9 Sub:20 RC:1 branch:master owner:MichaIng

  • Distro version | trixie

  • Kernel version | Linux DietPi 6.1.115-vendor-rk35xx #1 SMP Mon Dec 1 08:58:34 UTC 2025 aarch64 GNU/Linux

  • Architecture | arm64

  • SBC model | ROCK 5B (aarch64)

  • Power supply used | 30 W (5V-3A 9V-3A 12V-2.5A 15V-2A 20V-1.5A)

  • NVMe used | Kingston NV2 NVMe PCIe 4.0 1TB M.2 2280 -SNV2S/1000G

Additional Information

  • Software title | LibMali

Steps to reproduce

  • I followed this guide until step 5 and tried to run sudo apt-get install ./libmali-valhall-g610-g13p0-gbm_1.9-1_arm64.deb

Expected behavior

Actual behavior

  • I get the error: E: Unsupported file ./libmali-valhall-g610-g13p0-gbm_1.9-1_arm64.deb specified on command line.

apt-get does not support installation of local files, just use apt.

apt  install ./libmali-valhall-g610-g13p0-gbm_1.9-1_arm64.deb

BTW do you want to get HDR tone mapping working?
From the guide you posted:

For example, the Mali-G610 GPU on the RK3588 SoC is only used for OpenCL-based HDR tone-mapping.

So if you don’t need that you can skip that part and just follow the other steps.

i also don’t know how much DietPi already cares about that. Did you already try to just enable HW acc in jellyfin?

You could check with

ls -l /dev/mpp_service /dev/rga /dev/video*
ffmpeg -hwaccels

ALso jellyfin should log something about this when log level is set to debug and you try to transcode soemthing.

journalctl -u jellyfin -f

or you can just try hw acc with ffmpeg for testing purpose

ffmpeg -hide_banner -v debug \
    -init_hw_device rkmpp=rk \
    -i input.mp4 -c:v h264_rkmpp output.mp4

Yeah I have a monitor that supports HDR so I would like to get it to work.

When I try to run apt install ./libmali-valhall-g610-g13p0-gbm_1.9-1_arm64.deb I still get the same error.

ls -l /dev/mpp_service /dev/rga /dev/video*
ffmpeg -hwaccels

gives the following response

Just to be sure v1.9-1-55611b0 is the right version for DietPi, right?

This looks good.

You would need to instal ffmpeg to test this.

Can you try

dpkg -i ./libmali-valhall-g610-g13p0-gbm_1.9-1_arm64.deb
apt -f install

Can you try again with the jellyfin-ffmpeg

/usr/lib/jellyfin-ffmpeg/ffmpeg -hwaccels
/usr/lib/jellyfin-ffmpeg/ffmpeg \
  -hide_banner -v debug \
  -init_hw_device rkmpp=rk \
  -i input.mp4 -c:v h264_rkmpp output.mp4

Replace input.mp4 with an actual video file you have on the device.

You need to point to the deb file you’ve downloaded earlier.
