MovieMapper

Desktop application for organizing and managing movie and TV show collections. Scan media directories, extract metadata with FFmpeg, tag files as extras or commentary, and move them into Jellyfin-compatible folder structures — with a full audit trail.

Features

• Directory scanning — non-recursive folder browsing with real-time progress
• Metadata extraction — duration, video quality, and FPS via ffprobe
• File tagging — mark files as extra or commentary with visual state
• Jellyfin-compatible moves — tagged files move into spec-compliant folders (extras/, commentary/, behind the scenes/, ...)
• TheTVDB integration — search shows, browse seasons/episodes, map episodes to SxxExx naming convention
• Audit logging — every move/rename writes a .audit entry in the target directory; nothing happens silently
• Progress reporting — IPC-driven progress updates during scans

Architecture

Three implementations share the same core concepts (scanner → metadata → tagging → mapping → audit):

Getting started

Desktop app (Electron)

Prerequisites: Node.js 20+, npm, ffmpeg/ffprobe on PATH.

npm install
cp .env.example .env        # add your TVDB_API_KEY
npm start

Rust core

cargo build --workspace
cargo test --workspace

Rust CLI

The movie_mapper binary exposes the core as a command-line tool for scripting and headless use:

# List media files with metadata
movie-mapper scan /path/to/season [--json]

# Rename files to Jellyfin naming (Show S01E01 - Quality.ext)
movie-mapper map /path/to/season --show "The Show" --season 1 [--episode-start 1] [--dry-run]

# Tag / untag files (persisted to .moviemapper.json)
movie-mapper tag /path/to/media "behind the scenes"
movie-mapper untag /path/to/media "behind the scenes"

# Move tagged files into the Jellyfin folder for that tag
movie-mapper move /path/to/media "behind the scenes" [--dry-run]

# TheTVDB (requires TVDB_API_KEY)
movie-mapper tvdb search "Breaking Bad"
movie-mapper tvdb show 81189

# Show the audit log for a directory
movie-mapper audit /path/to/season

All destructive commands support --dry-run for a filesystem-safe preview. Every rename and move writes an entry to the directory's .audit log.

Configuration is read from ~/.config/movemapper/config.toml:

tvdb_api_key = "your-api-key"
media_dir = "/path/to/media"

Precedence for the API key: --tvdb-key flag > TVDB_API_KEY env var > config file.

Tests

npm test                    # vitest suite (JS)
cargo test --workspace      # Rust unit + integration

Configuration

Variable	Required	Description
TVDB_API_KEY	for TVDB search	TheTVDB v4 API token

Jellyfin folder compatibility

Moves target the Jellyfin extras folder specification: behind the scenes, deleted scenes, interviews, scenes, samples, shorts, featurettes, clips, other, extras, trailers, theme-music, backdrops.
