Trailerfin

Trailerfin is a tool for automatically retrieving and refreshing IMDb trailer links for your media library as the backdrop video. Instead of downloading the trailer locally, it will create a .strm file that Jellyfin can use to play the video.
It will check the expiration of the link and only update when the link has expired.

Features

• Scans directories for IMDb IDs and updates trailer links
• Fetches the latest trailer or video from IMDb
• Prioritizes trailers over clips when both are available
• Maintains an ignore list for movies without trailers
• Continuous monitoring mode for automatic updates
• Configurable via environment variables
• Docker and Docker Compose support
• Robust logging for monitoring and troubleshooting

Requirements

• Python 3.11+
• Docker (recommended)
• IMDb IDs in your media folder structure
• Make sure Theme videos are enabled in Settings > Display > Libraies per device

Setup

1. Clone the repository

git clone https://github.com/Pukabyte/trailerfin.git
cd trailerfin

2. Configure Environment Variables

Create a .env file in the project root with the following variables:

SCAN_PATH=/path/to/your/media
VIDEO_FILENAME=trailer.strm
WORKERS=4
VIDEO_START_TIME=10

• SCAN_PATH: Directory to scan for IMDb IDs
• VIDEO_FILENAME: Name of the .strm file to update
• WORKERS: Amount of workers to use

A sample docker-compose.yml is provided:

services:
  trailerfin:
    build: .
    container_name: trailerfin
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
    volumes:
      - /mnt:/mnt # Make sure this directory is where your content can be found in
