This tutorial is intended for beginners interested in compiling tvheadend with HW GPU transcoding (using iGPU form Intel gen 8+).
It is a little messy how Intel is combining CPU generations with GPU generations so before you buy a platform I strongly recommend you to check "
www.cpu-monkey.com" and "
www.cpu-world.com" to confirm your GPU is hardware capable decoding/encoding, Gen 9+ is recommended to 'low power encoders'.
I tested this methodology on following platforms:
- atomicpi (Atom x5-Z8350) iGPU gen 8 "Atom
x5-Z8350" downloading lubuntu 20.04 from:
http://ehxz.tk/atomicpi
Note: this CPU doesn't have the H264 Low Power Mode encoder
- gk41 celeron J4125 "
Amazon" iGPU 9.5 "celeron
J4125"
- NUC8 Compute Element with Pentium Gold 5405U "Compute
Element" iGPU 9.5 "Pentium Gold
5405U"
- NUC11 Compute Element with "Celeron 6305"
Date:
Jan 4, 2023.
HW:
NUC element with Pentium Gold 5405u
download ISO LUBUNTU 20.04:
https://www.cdimage.ubuntu.com/lubuntu/releases/20.04/release/
lubuntu-20.04.5-desktop-amd64.iso
flash ISO to USB 32G using rufus-3.21
Note: make sure you plug the USB stick in USB2.0 socket (black).
Install Lubuntu to PC with default settings; connect also to internet.
At boot you will see some i915 error about DRM ... don't worry.
Update some settings:
Preference / LXQt setting / Power Management: Idle --> uncheck Enable Idleness Watcher : Close
Preference / LXQt setting / Monitor Settings: 1280 x 720 : Save : Yes
Preference / LXQt setting / LXQt Configuration Center : Openbox Settings --> Desktops : Number of desktops : 1
Preference / Screen Saver : Mode : Disable screen saver
Install SSH:
System Tools / QTerminal
sudo apt update
sudo apt install ssh
check status:
systemctl status sshd.service
You should see is Active.
if is not working:
sudo systemctl enable sshd
and:
sudo systemctl start sshd
I prefer to connect over SSH to continue, but you can remain in terminal (on desktop):
Update to latest kernel version:
sudo apt update
sudo apt upgrade
sudo reboot
sudo apt autoremove --purge

OPTION 1: Gen8 / Gen9 / Gen9.5
Install required development packages:
https://www.linuxfordevices.com/tutorials/ubuntu/install-intel-graphic-drivers
Note:
- some packages are already installed ... but is no harm to install them again.
check:
sudo lspci -nn | grep -e VGA
alin@alin-cm8pcb4r:~$ sudo lspci -nn | grep -e VGA
00:02.0 VGA compatible controller [0300]: Intel Corporation Device [8086:3ea1] (rev 02)
you can go on:
https://dgpu-docs.intel.com/devices/hardware-table.html
and search for: "3ea1" (check after [8086:****]).
and see is: IntelĀ® UHD Graphics 610 --> Gen 9 --> Coffee Lake
sudo apt install mesa-utils
sudo apt autoremove
Now, enter the following command to get the driver details. It will also give you other GPU details along with driver details.
in Desktop (not SSH):

END OPTION 2
Configuring permissions:
To access GPU capabilities, a user needs to have the correct permissions. The following will list the group assigned ownership of the render nodes, and list the groups the active user is a member of:
stat -c "%G" /dev/dri/render*
alin@alin-cm8pcb4r:~$ stat -c "%G" /dev/dri/render*
render
My expectation is that you receive 'render' ... but you might receive also other names (like video). In that case you have to replace in commands below the 'render' with 'video' (or what ever you receive).
Now we check if user is part of that group:
groups ${USER}
alin@alin-cm8pcb4r:~$ groups ${USER}
alin : alin adm cdrom sudo dip plugdev lpadmin sambashare
--> as expected is not.
we add user to group 'render' (or video if you received video above):
sudo gpasswd -a ${USER} render
newgrp render
Now we have to verify that actual user is part of render (or video):
groups ${USER}
alin@alin-cm8pcb4r:~$ groups ${USER}
alin : alin adm cdrom sudo dip plugdev render lpadmin sambashare
Note we have render in the list.
Update to latest:
sudo apt update
sudo apt upgrade
Install gpu tools (required to check the work load on GPU):
sudo apt install intel-gpu-tools
Enable GUC firmware (this is a must for encoding with low power codec):
we need to generate a file:
sudo vi /etc/modprobe.d/i915.conf
with the text (only one line) --> press key 'I':
OPTION 1: Gen8 / Gen9 / Gen9.5
options i915 enable_guc=2
END OPTION 1
OPTION 2: Gen11+
options i915 enable_guc=3
END OPTION 2
--> press key : and w
--> press key : and q
sudo update-initramfs -k all -u
sudo update-grub
sudo reboot
Verify GuC was enabled:
dmesg | grep guc
OPTION 1: Gen8 / Gen9 / Gen9.5
alin@alin-cm8pcb4r:~$ dmesg | grep guc
[ 1.460690] Setting dangerous option enable_guc - tainting kernel

From this last log you need to copy the file name bolded (in your case will have a different number after '4.3-')
In my case is:
tvheadend_4.3-2063~gd88549603~focal_amd64.deb
cd ..
Install tvheadend:
sudo dpkg -i tvheadend_4.3-2063~gd88549603~focal_amd64.deb
Intel GPU:
sudo apt install i965-va-driver-shaders
We have to add also user hts to render (or your group that has access to GPU):
sudo gpasswd -a hts render
newgrp render
verify:
groups hts
alin@alin-cm8pcb4r:~$ groups hts
hts : hts render
Now we see user is part of render.
start tvheadend:
sudo systemctl start tvheadend.service

2022-12-09 10:53:37.821 transcode: 0001: 01:MPEG2VIDEO: ==> Using profile h264_vaapi
2022-12-09 10:53:37.822 transcode: 0001: 02:AC3: ==> Using profile webtv-aac
To confirm you are using GPU for trancoding you need to send:
sudo intel_gpu_top
When you don't have any streams open you will see all numbers: 0; after you open streams you should see values non-zero in: Render/3D , Video and VideoEnhance.
Next we enable 'low power' encoding.
For that we need to use ffmpeg + spwan (because tvheadend is not supporting this feature natively). This will come with some limitation (like you have to use http instead of htsp for transport, Kodi client will require this feature to be enabled by hand).
Install ffmpeg:
sudo apt install ffmpeg
We check the location of ffmpeg:
which ffmpeg
alin@alin-cm8pcb4r:~$ which ffmpeg
/usr/bin/ffmpeg
We have to create a spawn profile:
[browser menus]:
Configuration / Stream / Stream Profiles --> Add

Profile name: fh264
Enabled: checked
Default: checked
Comment: ...

To confirm you are using GPU for trancoding you need to send:
sudo intel_gpu_top
When you don't have any streams open you will see all numbers: 0; after you open streams you should see values zero for Render/3D and non-zero in: Video and VideoEnhance.
Also you shuld see a power consumption differece (CLK freq difference) on first row.
In my particular tests (720p60 mpeg2-->h264):
- without low power (native tvh): 360 --> 410 MHz with average 0.8W
- with low power (ffmpeg): 290 -- 370 MHz with average 0.4W
After we manage to implement low power natively in tvh I will update this tutorial.

This is a very good source of info ... there is only one info that I could not find: iGPU encoders/decoders available. cpu-monkey has a "Hardware Codec support' section very useful to select a CPU (when you have a target encoding scheme in mind, before you have the HW).

Frankly I don't know this combination "server OS with Kodi GUI" ... I consider my self a beginner and Lubuntu selection was with 'low resources' in mind. I think this comes down to personal preferences (in the end), and how comfortable each user is with GUI versus CLI. I think is obvious that Server is the most fit option (if you know what to select during install process). The tutorial is less focused on 'Os install + most fit install' and more towards 'If you are a beginner what CPU to select to achieve HW encoding with iGPU'.
For example: how you know (before you buy the CPU) how many streams you will be able to transcode (for a particular combination: as example 1080p h264 --> 1080p h264 30p) in real time? I don't have this answer ... I see (on reports over internet) an increase of the number of streams with increase in 'Shader', 'Execution units' and max GPU CLK. Probably we should start a separate thread in order to report the results (with various CPU) and build a 'database' that can be accessed by users before ordering some particular HW.
I can't continue the tutorial because there seems to be a problem with Intel repository ( I can't install vainfo). Hopefully will be fixed soon.

For NVIDIA there is a big list from PLEX community "

There is a simple way to do GPU benchmark with FFMPEG
/FFMpeg need Intel "library's
ONEApi" /
Run multiple time simultaneous trascoding until frame rate is ~25% more fps then source.

This is only for Gen11+; for Gen9+ (up to 11) I was planing to use ffmpeg + libmfx for QSV. VAAPI should work without problems even with 'stock ffmpeg'.

Alin, thanks a lot for your post about decoding (mersi mult :-)
I just want to ask if it's possible to use it when I have TVH installed in docker please...
It is possible ?
I use a Nuc with a i7 CPU and Iris Plus Graphics 650 (rev 06) GPU,
and Astrometa DVB-T2 Tuner.
Thanks in advance
Denis
Alin Gherghescu
Sorry, I am not using dockers ... I don't have experience with dockers.

Thanks a lot... I'll try on Ubuntu that I have installed on that NUC
I so that the Media SDK is deprecated,
do you know if will this work also using IntelĀ® ?

Can you tell me the CPU model name (use 'lscpu').
Example output:
Model name: 11th Gen Intel(R) Core(TM) i5-1135G7 @ 2.40GHz
What Ubuntu is installed?
I assume you are trying to transcode: what input resolution/codec into what resolution/codec? How many simultaneous streams?

I use Ubuntu 22.04 on that NUC.
And a tuner "Astrometa DVB-T2 Tuner." via USB.
I need only one streaming of romanian DIGI channel.
At my home in Romania I have a fiber modem of DIGI and I take the DVB-C from that one.
I don't need a 4K or high quality streaming... I just need a clean HD image without interruptions (like now).
Now I have TVH in a docker, but I will install it on the primary OS in some days,
but I don't know witch step by step guide to use.
Is better if I compile it for my OS or I can use a .deb please ?
Thanks a lot for the help
Denis
Alin Gherghescu
I installed latest tvheadend to Lubuntu 22.04, I can share my notes.
I can share with you the deb generated ... but is not wise to install deb-s that are shared by users on forums :) .
deb was compiled with:
alin@alin-nuc11pahi5:~$ uname -a
Linux alin-nuc11pahi5 5.15.0-76-generic #83-Ubuntu SMP Thu Jun 15 19:16:32 UTC 2023 x86_64 x86_64 x86_64 GNU/Linux
Anyway that will only save you few commands ... so my advise is to follow commands from my notes (in that order).
If you want to stay with containers (for some reason), You should know that there is another option: Jellyfin.
https://jellyfin.org/docs/general/installation/container
https://hub.docker.com/r/linuxserver/jellyfin
make sure you install/read:
https://jellyfin.org/docs/general/administration/hardware-acceleration/
https://jellyfin.org/docs/general/administration/hardware-acceleration/intel
you will need to connect Jellyfin to tvheadend using:
https://jellyfin.org/docs/general/server/plugins/tvheadend/
In this case Jellyfin will trancode and tvheadend will deliver the video/audio with 'pass' (without any transformation/change).
Personally I didn't liked the clients for Jellyfin ... but you might have a different opinion.

Thanks a lot for your help,
as soon as I'll have some time (after christmas days :-),
I'll try to make some updates.
I think I'll try the codec first, and if will work, I'll try the TVH,
Thanks again

Hello,
Thank you for your instructions.
I have two almost identical Dell Wyse:
Test system - Intel J4105, 8GB RAM, 256 GB SSD
Live system - Intel J5005, 16GB RAM, 256 GB SSD, 16GB eMMC
The OS is Debian 12-7 on both PCs.
(bought for a few euros as a leased return)
I'm not a Linux pro š - I test the packages on my test system first - if everything works, later on the live system.
I want to compile tvh on the test system and then install the
TVH-XYZ.deb on the live system.
Does that work?
Are all codecs etc. in the installation package?
Or do I have to install something on the live system first?
Thanks for the answer.

I never tried my self ... I prefer to compile on the machine needed.
In theory should work (assuming you have the same kernel and packages installed).
Are all codecs etc. in the installation package?
codecs as 'the piece of code that is transcoding for you' is not part of TVH; is part of intel drivers. In the first post everything that is before line "./Autobuild.sh" has to be performed for both PCs. Also the part "Intel GPU" --> "start tvheadend" is required (for user permission).
I don't know your constrains but: why not compiling on both PCs?
BTW: in your config "vaapi: no" --> all point of this thread is to transcode with vaapi + GPU; based on your configuration you don't compile with vaapi suport.

Hello,
I have some other important databases on this PC.
I don't want to destroy anything here. You have to install a lot of packages to compile.
But I went back to the Synology.
There were just new App-Updates with GPU codec and ffmpeg 6/7.
So you have to have at least Python3, GPU driver and ffmpeg installed on the server.
