Note: This script is compatible with the Jellyfin-VideoOSD-CustomOnOff-Menu.

Jellyfin VideoOSD Download Button

Credits go to HighImKevin from the Jellyfin Community, who helped me finalize this script after I was stuck on an issue for quite a while. Thanks again for the support!

Tested on Windows 11 on Chrome:

Adds a convenient Download button directly to the VideoOSD in Jellyfin Web. With one click, you can download the currently playing video as a 1:1 original file into your default download folder. No menu diving. No playback interruption. Just click and download.

---

What It Does

• Injects a Download button into the VideoOSD interface
• Detects the currently active video
• Triggers a direct file download via Jellyfin’s API
• Automatically adapts when navigating between videos
• Does not interrupt playback

The downloaded file is identical to the source file on the server.
No transcoding. No quality loss.

How It Works

The script:

1. Detects the current video ID from the VideoOSD DOM
2. Builds a download URL using:
   • ApiClient.serverAddress()
   • ApiClient.accessToken()
3. Creates a temporary hidden <a> element
4. Triggers the browser’s native download mechanism
5. Uses a MutationObserver to:
   • Detect dynamic page changes
   • Re-inject the button if necessary
   • Track video changes

Because it uses Jellyfin’s native /Items/{id}/Download endpoint, the file you receive is the exact original media file stored on the server.

Why It’s Useful

Normally, downloading a video in Jellyfin requires opening the item menu and selecting Download.

This script:

• Saves clicks
• Makes downloading faster and more accessible
• Keeps the download action directly inside the player UI
• Avoids interrupting playback

It’s especially useful if you frequently download media for offline use.
