• See Compatibility list and please add a comment if compatible or not with yours.
• Releases are created automatically from the latest jellyfin releases and are not field-tested nor official ones from Jellyfin or QNAP.
• The latest release with my 👍 is deployed on my QNAP and working properly.

• Download the .qpkg from the Releases
• On the Qnap QTS > App Center > Settings > Allow installation of applications without a valid digital signature
• On the Qnap QTS > App Center > Install Manually. then choose the downloaded .qpkg.
• After installation, on the Jellyfin appearing in the App Center, just wait a bit (~30s) then open it using the Open button. It shall open a working web site.
• If it is the first time you open, you will have to choose a server (which is the IP of your NAS) and create an user
• If you watch jellyfin on your TV (or so) using Jellyfin Android version (or other), your NAS should then be accessible from it. Just add the NAS ip to access it.

(中文)

Go to Admin > Dashboard Server > Playback

• Transcoding > Hardware acceleration : Video Acceleration API (VAAPI)
• Transcoding > VA API Device: /dev/dri/renderD128

This shall be OK, but maybe not.

Go to Admin > Dashboard

• You can find a log of vainfo of your NAS under Advanced > Logs > vainfo-*.log. It will helps you to find which driver or options to enable.

• A dedicated plugin is now installed by default on the Jellyfin server (Plugins > QNAP.Configuration), you can change the default vaapi driver used while loading a video. (from defaultValue to iHD or i965).

• Disable some unexpected enabled options Server > Playback > Transcoding:

  • On TS-253A, the option Enable 10-Bit hardware decoding for HEVC shall be disabled

Is it possible to change the default http port of Jellyfin.

Go to Administration > Dashboard > Advanced > Networking

• Change the Server Address Settings > Local HTTP port number, go to QNAP App Center and do Stop and Start on the Jellyfin.

• Hopefully, if you open Jellyfin with the new port number, it shall open it.

Is it possible to enable HTTPS for Jellyfin.

Go to Administration > Dashboard > Advanced > Networking

• Enable the HTTPS accordingly and change the Server Address Settings > Local HTTPS port number if needed.

• Put the path towards your p12 certificate if you have some. (if not, see below how to generate one for your Jellyfin server)

• Go to QNAP App Center and do Stop and Start on the Jellyfin.

• Hopefully, if you open Jellyfin with the new HTTPS port number, it shall open it.

You can use directly the certificate of your NAS (download it and generate a p12 from it), or create a new one. Below are the steps to create a child certificate from the QNAP one.

Download your QNAP NAS certificate

System > Security > SSH and certificates > Download certificate and private key

Create a private key for the new certificate

openssl genrsa -out newkey.key 2048

Create a configuration openssl-cert.conf

[req]
distinguished_name = req_distinguished_name
req_extensions = req_ext
prompt = no

[req_distinguished_name]
C   = FR
ST  = Paris
L   = Paris
O   = pdulvp
CN  = Jellyfin QNAP

[req_ext]
subjectAltName = @alt_names

[alt_names]
IP.1 = 192.168.1.xxx
DNS.1 = nasfxxxxxx

Create a sign request

openssl req -new -key newkey.key -out newcsr.csr -config openssl-cert.conf

Create a certificate

openssl x509 -req -in newcsr.csr -CA SSLcertificate.crt -CAkey SSLprivatekey.key -CAcreateserial -out jellyfincert.crt -days 365 -extensions req_ext -extfile openssl-cert.conf

Package the certificate

openssl pkcs12 -export -out jellyfincert.p12 -inkey newkey.key -in jellyfincert.crt -certfile SSLcertificate.crt

Reference it in Jellyfin

Start and stop Jellyfin in the QNAP App Center

On your client, Install the certificate as Trusted. Whether the Jellyfin one (Right Click on CRT, Install Certificate > Local Machine (or current user) > Automatically select the certificate) or the QNAP one as Trusted Root Certificate (Right Click on CRT, Install Certificate > Local Machine (or current user) > Place all certificates on the following store > Trusted Root Certification Authorities). With this last option, all childs certificates of your NAS are trusted. (Restart your PC)

Open Jellyfin, it shall work.

Now you shall reconnect to the server using HTTPS

Now, you can customize the startup of Jellyfin by creating a new file user-config.sh in the installation folder, rather than editing provided scripts. It will not be erased after updates. (look at user-config.sh.sample provided aside)

To add a shortcut onto the HybridDesk Station, you can use @pdulvp/jellyfin-qnap-hd

You can use my alternative store link on the App Center to retrieve automatic updates. See pdulvp.fr/qnap-store

• WSL debian bullseye with rsync and jq installed
• QDK2 : https://github.com/qnap-dev/qdk2/releases
• Visual Studio 2022

• Launch a Release build of the plugins/Jellyfin.Plugin.QnapConfiguration.sln under Visual Studio. It will create two releases, for net5.0 and net6.0 that will be embedded afterwards.
• Launch ./make.sh (note that the script will try to push it on this repository. push.sh can be disabled in subscripts fetch-stable.sh and fetch-stable-pre.sh)
• If there is some 'File not found' while downloading dependencies, just launch a sudo apt-get update on your WSL and relaunch the build
• The build is verbose and raises some logs on tar operations but shall not ring a bell

It is large as it embeds Jellyfin Server, Jellyfin FFMPEG and Jellyfin Web Client and most of their dependencies. Jellyfin and ffmpeg require some dependencies that are not available on most QNAP NAS default installation (latest releases of libc or stuff) so it embeds almost all dependencies in it to be able to be launched. Dependencies and custom installed jellyfin plugin.
