I am no longer updating this guide as of 12/03/2024 – Use the TubeArchivist guide as it provides the same functionality and has much more active development.

What is YouTubeDL Material?

YouTubeDL Material is nice web front end for YoutubeDL, This is a tool that is used to download video from YouTube and many other sites. This is useful for if you want copies of videos to watch locally – You can also subscribe to channels.

Let’s Begin

In this guide I am going to take you through the steps to get YoutubeDL Material up and running in Docker on your Synology NAS. We will be using the new Projects (Docker Compose) feature to get this running as it will save you time vs manual setup using the normal UI.

In order for you to successfully use this guide please complete the steps below first.

Folder Setup

Let’s start by getting some folders set up for the container to use. Open up File Station create the following.



Container Manager

Next we are going to set up a ‘Project’ in Container Manager. Open up Container Manager and click on Project then on the right-hand side click ‘Create’.

In the next screen we will set up our General Settings, enter the following:

Project Name:youtubedl
Source:Create docker-compose.yml

Next we are going to drop in our docker compose configuration, copy all the code in the box below and paste it into line ‘1’ just like the screenshot.

What on earth is a Docker Compose?
Docker Compose allows us to define how Docker should set up one or more containers within a single configuration file. This file is yaml formatted and Container Manager uses the Projects feature to manage them.
    image: tzahi12345/youtubedl-material:nightly
    container_name: youtubedl-material
      - UID=1234 #CHANGE_TO_YOUR_UID
      - GID=65432 #CHANGE_TO_YOUR_GID
      - USER=youtube
      - ytdl_default_downloader=yt-dlp
      - ytdl_use_local_db=true
      - ytdl_port=9998
      - write_ytdl_config=true
      - /volume1/data/media/youtube/users:/app/users:rw
      - /volume1/data/media/youtube/subscriptions:/app/subscriptions:rw
      - /volume1/data/media/youtube/audio:/app/audio:rw
      - /volume1/data/media/youtube/video:/app/video:rw
      - /volume1/docker/youtubedl:/app/appdata:rw
      - 9998:9998/tcp
    network_mode: synobridge
      - no-new-privileges:true
    restart: always

Environment Variables

We are now going to amend some key variables to make sure the container has access to our folders and also knows where we are in the world. Any I don’t mention leave as they are.

UID(required) The UID you obtained in the user setup guide
GID(required) The GID you obtained in the user setup guide

Once you have made the edits you can click ‘Next’

You do not need to enable anything on the ‘Web portal settings’ screen click ‘Next’ again.

On the final screen click ‘Done’ which will begin the download of the container images and once downloaded they will be launched!

The images will now be downloaded and extracted. You should see ‘Code 0’ when it has finished.

Firewall Exceptions

(Skip if you don’t have the Firewall configured)

If you have enabled and configured the Synology Firewall you will need to create exceptions for any containers that have a Web UI or have any incoming or outgoing connections. This section covers the basics of how to add these. (Please note this is a generic section and will not show the specific ports used in this guide however it applies in the same way)

Also, I would like to refer people to the great guide on getting the Firewall correctly configured over on WunderTechs site.

Head into the Control Panel> Security > Firewall, from here click Edit Rules for the profile you set up when you enabled the Firewall.

Next click on Create and you will see the screen below. Source IP and Action will be automatically selected to All and Allow, I will leave it up to you as to your own preference on whether you want to lock down specific Source IPs from having access. In this example we will leave as All.

You will now choose ‘Custom‘ and then the Custom button

Now select Destination from the drop-down menu, most web based containers require TCP access but check the guide as it will show the port and protocol. Then add comma separated ports. Then press OK.

Click OK a couple of times to get back to the main screen. You will see by default the new rule is added to the bottom of the list. You must always have your Block All rule last in the list as the rules are applied top down so move your container up.

You have now completed the Firewall changes and can continue with the guide.

Container set up finished

You should now be able to access the web interface via the IP of your NAS followed by the port 9998


You can use the main screen to download individual videos by pasting the URL and selecting the quality, or if you want to add subscriptions to specific channels use the menu on the left.

I recommend going into the advanced settings and amending the downloader to ‘yt-dlp’ if you have any issues pulling videos.

    Just add the following mapping and it will prompt a download error. I have checked the path and there is no problem

    – /volume1/ytdl/youtube/users:/app/users:rw
    – /volume1/ytdl/youtube/subscriptions:/app/subscriptions:rw
    – /volume1/ytdl/youtube/audio:/app/audio:rw
    – /volume1/ytdl/youtube/video:/app/video:rw
    – /volume1/docker/youtubedl:/app/appdata:rw

    Starting the container with the default unmapped folder to download videos is not a problem

    Any ideas why the container keeps going from green to grey and not letting me fully start it up? All instructions followed.

    Followed the instructions to a T but the container keeps going from green to grey and won’t stay turned on. Cannot connect via IP address.

      I am just about to change the image to the nightly version as there is a new bug in ‘latest’ that has not received the fix yet.

      See the yaml in the guide in about 10 mins you will see the image line has changed, just update your yaml in line.

        switching to nightly worked for me for a while but now im getting a differnt error ” skipping player responce from web client”. i suspect a new bug is present and i may just have to wait for them to fix it. but if you have any other sugestions let me know

          This sounds like another bug, I am looking at doing a guide for Its more of a YouTube Archiver rather than individual files, also looking for another tool to replace YouTubeDL Material for individual video grabbing as this one has had a bit of a rough time dev wise.

        • Dr_Frankenstein Dr_Frankenstein

          Just read the documentation and TubeArchivist can download single videos as well! – Watch this space as a new guide will come along shortly and this one will likely hit the archive..

    Please consider rewriting the “Folder Setup” section as it is easy to miss the steps, especially if one is used to most of the other guides and hasn’t finished their first cup of coffee. Something like:

    Folder Setup

    Our first task is to set up some folders for YoutubeDL Material to store its configuration files.

    Open up Filestation and go to the /docker share. Create a folder called ‘youtubedl’.

    Then, within the projects folder we created in the preceding guide create another folder called ‘youtubedl’.

    … and continue the guide from there.

    And then maybe change the picture to show the three folder elements separately: /volume1/docker/youtubedl, /volume1/docker/projects/youtubedl, and the tree under /volume1/data/media/youtube. The current picture makes it seem like their are only two changes as their are only two boxes. Maybe use arrows?

    Great stuff as usual!

      Thanks for the feedback – I have made the amendments, I also tweaked the folders to line up with how I am doing the projects folder to help differentiate them.
