Synology Jellyfin H/W Transcoding Complete Guide in 5 Minute.

[Peter Suh]

 

I will tell you how to install Docker super-simple to activate Intel iGPU opencl transcoding.

You only need to have Docker (Container Manager) ready on Synology.

I tested DSM version 7.2.2.

 

1. First, connect via ssh and install ffmpeg dedicated to jellyfin by executing the command below.

This is an essential program for Intel iGPU H/W transcoding.

 

sudo -i
bash -c "$(curl https://raw.githubusercontent.com/PeterSuh-Q3/tinycore-redpill/main/jelly.sh)"

 

I will write the contents of this script here for reference only.

 

#!bin/sh

mkdir -p /docker/jellyfin/config
mkdir -p /docker/jellyfin/cache

curl -kLO# https://github.com/jellyfin/jellyfin-ffmpeg/releases/download/v6.0.1-8/jellyfin-ffmpeg6_6.0.1-8-bookworm_amd64.deb
dpkg-deb -x jellyfin-ffmpeg*.deb temp_dir
mkdir -p /usr/lib/jellyfin-ffmpeg
mv -v temp_dir/usr/lib/jellyfin-ffmpeg/ /usr/lib/
cd /usr/lib/jellyfin-ffmpeg
./ffmpeg

 

ffmpeg version 6.0.1-Jellyfin Copyright (c) 2000-2023 the FFmpeg developers 
  built with gcc 14.1.0 (crosstool-NG 1.26.0.93_a87bf7f)

 

 

2. Create a project in the container manager.
For detailed instructions on creating a project in the container manager, please refer to this KB.

https://kb.synology.com/en-id/DSM/help/ContainerManager/docker_project?version=7

 

You can download the yaml file required for creating a docker project from this link and use it,

or you can copy and paste this content.

The option to activate Intel opencl for transcoding is

The value below is automatically added to one of the environment variables.

 

- DOCKER_MODS=linuxserver/mods:jellyfin-opencl-intel

 

version: '3.x'
services:
  jellyfin:
    image: jellyfin/jellyfin:latest
    container_name: jellyfin-igpu
    environment:
        - UID=1026
        - GID=100
        - TZ=Asia/Seoul
        - DOCKER_MODS=linuxserver/mods:jellyfin-opencl-intel
    network_mode: 'host'
    ports:
      - 8096:8096
    volumes:
      - ./config:/config
      - ./cache:/cache
      - /volume1/_DRAMA:/volume1/_DRAMA
      - /usr/lib/jellyfin-ffmpeg:/ffmpeg
    devices:
      - "/dev/dri/card0:/dev/dri/card0"
      - "/dev/dri/renderD128:/dev/dri/renderD128"
    privileged: true
    restart: always

 

When setting the volume, please modify "/volume1/_DRAMA:/volume1/_DRAMA" appropriately to suit your movie shared folder situation.

 

3. Activate jellyfin dashboard transcoding

From the home screen, go to the 3-line settings menu->Dashboard->Playback->Transcoding, and activate all items in VAAPI as shown below.

Please do not touch the low power mode as shown in this capture. It will immediately fall into an error and playback will stop from the beginning.

 

 

4. For the transcoding test, play a video and in the wheel-shaped settings,

When using 1080p resolution as the standard, lower the quality to 720p or 480p, and

If transcoding is done well, select the [Playback Data] option in the wheel-shaped settings,

and the details will be displayed in the upper left corner of the movie.

If you see the word transcoding, check the CPU load of Synology.

If you maintain an appropriately low load, it will be successful.
