Trailarr is an application that discovers, downloads, converts and organizes trailers for media managed by Radarr and Sonarr. It integrates with multiple instances, follows common media naming conventions, and provides a responsive UI to review and manage trailer files.
Key Features
- Manages multiple Radarr and Sonarr instances to locate media and associated trailers
- Detects existing trailers and avoids duplicates
- Downloads trailers using yt-dlp and processes them with ffmpeg (conversion and trimming)
- Organizes trailers in media folders following Plex/Emby/Jellyfin naming conventions
- Customizable profiles for quality, filters and download behavior (including wait times)
- Responsive Angular frontend for browsing media and managing trailer tasks
- FastAPI backend with an ASGI server for API-driven operations
- Docker-based deployment with optional hardware acceleration (VAAPI) for faster transcoding
Use Cases
- Populate trailers for a Plex, Emby or Jellyfin library managed by Radarr/Sonarr
- Automatically download and convert trailers for newly added movies or episodes
- Maintain consistent trailer file naming and formats across multiple media servers
Limitations and Considerations
- Plex integration for sending notifications and triggering scans is planned but not currently implemented
- Hardware acceleration support depends on host GPU and driver support (VAAPI for Intel/AMD only)
- Path mappings and permissions can require manual configuration when containers and media hosts differ
Trailarr is suited for users who want automated, configurable trailer management tightly integrated with Radarr and Sonarr. It focuses on reliability of downloads, file organization, and lightweight processing rather than media server functionality.
