Ubuntu Intel N5105 QSV HW Transcoder not detected

[engSherv]

yea sorry about the cpu i think i mentioned somewhere in one of my comments, i also had opened a forum here link.

after my second reboot my hw transcoding start working and i think indeed the problem might have been the permissions.

maybe try to replicate what i have done and see if it will fix the problem.

in the omv dashboard goto users and then users again create new users with the following group

idk if the reboot is needed but i think after rebooting after this step my hw transcoding starts working

because i first did this

echo "options i915 enable_guc=2" >> /etc/modprobe.d/i915.conf
update-initramfs -u

rebooted and create a user and container and didn’t work then i just reboot because of another container and the hw transcoding was working.

i am a very noob in the Linux.
here also my current log as well i tried 3 4k transcodings and it was done very easily

While this isn’t on a N-series. It is abstracted and running on the OMV runtimes.

(I wanted to make certain the core OMV distro was ok)

If you’re curious – Plex (.DEB file) installed on the native OS via command line.

@ChuckPa

If you’re curious – Plex (.DEB file) installed on the native OS via command line.

is there an advantage to running the plex native instead of the container in docker?

also, was the solution same as mine in the user group ?

[ChuckPa]

The container is an abstraction of the application from the OS.

That’s why you have to MAP everything into it.

I am very old-school when it comes to some things.

I run a different kind of container.

Rather than running Docker, I run it as LXC (Linux container) where it virtualizes the whole OS at no additional cost.

Now I install native apps in the LXC . (all my media bots run in one LXC)

On NAS boxes (qnap, synology, asustor, etc), running the native app is really the best way.

On OMV, because Plex doesn’t support it, your only choice is docker. That works but comes with the pain of all the mapping.

For OMV, what I created (via the command line) was:

1. Made a symlink for md0 (i’m lazy and it’ll never change)
2. Created a shared folder for the media on my main NAS
3. Created a user for myself (UID=1000) and added to both video and render groups
4. Created the required directories to support the container environment
5. Launched and claimed

root@omv:/md0# cat dockerplex-1292 
sudo docker stop plex
sudo docker rm plex

# Remove old image if exists
Image="$(sudo docker images | grep -i plex | awk '{print $3}')"

if [ "$Image" != "" ]; then

  sudo docker stop plex
  sudo docker stop plex
  sudo docker rm plex
  sudo docker rmi -f $Image

@ChuckPa

-e PLEX_UID=1000 \
-e PLEX_GID=0 \

out of curiosity what are those env variables you are defining?

i have heard of something similar to what you have described it was on proxmox if i dont mistake but my issue is i have 2 8tb external HDD that i like to act is media storgae and the omv gui is seems very easy to navigate and manage i have seen if i switch to proxmox and do the LXC container thing i use actually less resources compare to my current setup.

but thanks for the help i appreciate it

[ChuckPa]

These are the UID / GID for the Plex processes.

PLEX_UID / PLEX_GID

• are equivalent to

PUID / PGID

PUID / PGID works for both PlexDocker and LinuxServer docker

Just found this thread as I discovered this morning my server is also not hardware transcoding anymore (used to do it). Whats the recommended fix proposed? I’m on 1.30.1.6497

[Zillon]

Fixed it - removed beignet; reinstalled intel open cli. Clinfo shows it working now; Plex install shows i916 hardware there and transcoding via hardware now working again.

[ChuckPa]

Info: that’s an i915

If you have TrueHD audio tracks, check them. There is a known issue with TrueHD for some users (many).

If this impacts you too, the last known working is 1.29.2 .

Keep your kernel as you have it.

Hardware decoder still has issues with my N5105 server.

In this post (Ubuntu Intel N5105 QSV HW Transcoder not detected - #50 by ChuckPa), you tested on ubuntu 20.04 with 5.15-48 kernel .

So I reinstall my server with official ubuntu 20.04.5 image
AND Installed native package plexmediaserver_1.29.2.6364-6d72b0cf6_amd64.deb without any modifications after system install was complete.

But hardware decoder still not working .

Then trying clear up and update plexmediaserver to 1.30.2.6563 and get same error. here is log for both version:
1.30.2.6563.zip (215.8 KB)
1.29.2.6364.zip (233.7 KB)

My server looks like this (uname & dmesg & /dev/dri & modinfo shell output):

lol. yes, I just presumed any intel QSV fix would be the same TBH.

[pshanew]

Can you provide the output of running dmesg | grep -i i915 on this system? You may need to sudo it.

This error from your logs makes me think you either don’t have GuC enabled at all, or that the required firmware blob to utilize it is missing from your system. The dmesg output will confirm (or disprove) this.

Jan 15, 2023 07:21:36.408 [0x7fe9d9225b38] ERROR - [Req#c16/Transcode/stx8jz4cyjq82y6hl1xsl9oo/c316a296-79c3-41f4-9f7c-2257d4555209] [h264_vaapi @ 0x7f9354ba2080] Driver does not support any RC mode compatible with selected options (supported modes: CQP).

I saw this same error on my server before sorting out the problem I described above. In my case I had to manually install the required GuC firmware blob.

It doesn’t appear to be initializing the GuC. Did you try the steps in this how-to yet?

Linux Tips

Transcoding and tone mapping with JasperLake / ElkhartLake CPUs This tip / How-To is entirely NOT-SUPPORTED by Plex. You, as the system’s owner/admin assume all risk/liability for the kernel integrity It may work for you and it may not. There are no guarantees. There has been success with for some users. Your results may vary. This How-To is written for Ubuntu/Debian distributions but should be applicable to others. Replace inte-media-va-driver with intel-media-va-driver-non-free A…

If not, please do. If it still doesn’t transcode using hardware, please provide fresh server logs and the output of dmesg | grep -i i915 again.

[ChuckPa]

GUC / HUC issues we’re seeing is because the kernels aren’t keeping up with hardware demand.

Enabling GUC mode 2 helps in most cases but not guaranteed.

Updating the i915 firmware is the better solution but dependent on OS and kernel version as well as hardware being used.

nope, still not working, logs and dmesg:

I gave up, thanks for you help anyway.

hardware transcode is working on a QNAP NAS with j4025 cpu, but this cpu is too weak, it can’t decode videos with bitrate higher than 30Mbps and will freeze.

I will use QNAP NAS for a while, until linux 6.x LTS kernel is release and ubuntu server is update to it, may be i will try again.

and thanks~

Morning.

Where to get the newest firmware for your processor (better than what comes with the distro)

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915

[plex82986]

already tried this last night, not working. and do some google:

from this github issue (GuC for Jasper Lake (Celeron N5095) · Issue #1352 · intel/media-driver · GitHub) post by intel developer:

you can not just update GuC driver without kernel.

and from this blog (N5105 软路由安装 ESXi 7 直通核显给 Debian / Ubuntu 虚拟机通过 Docker 实现 jellyfin 硬件转码视频文件（硬解/编码）) shows N5105 need at least 5.17 kernel & ehl_guc_69.0.3.bin to work.

I tryed use ehl_guc_69.0.3.bin with the 5.15-58 kernel distribute with Ubuntu 20.04, no effect.

so i gave up, and wait the new LTS kernel
