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.

I did point it to the deb file but apparently it didn’t like that it was stored at the root of the drive.

Placing it in /root/my-ente and then running cd my-ente made the error go away.

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

after which the terminal no longer accepts inputs.

This is fine, dpkg unpacks the deb file and apt -f install installs possible dependencies, but looks like there are none.

Looks also good, also the ffmpeg command does not complain anymore about missing rkmpp anymore, only about that you pointed to an input file which does not exist (or maybe you have no permission to access it)

This is also expected, the -f option holds it in live view. So you do the journalctl command and in another terminal you can do something with jellyfin and you will see the log in real time.

Looks all good now?!

Yeah I checked that it’s working and it seems to do
