Program Director

AI-powered TV channel programmer for Tunarr written in Go.

Overview

Program Director generates themed channel programming in Tunarr by:

1. Syncing media metadata from Radarr and Sonarr to local database
2. Using similarity scoring and LLM (Ollama) to intelligently select content matching themes
3. Applying generated playlists to Tunarr channels with cooldown tracking

Features

• AI-Powered Selection: Uses Ollama LLM for intelligent media curation
• Theme-Based Playlists: Configure themes with genres, keywords, and scheduling
• Database-Backed: SQLite or PostgreSQL for media caching and cooldown tracking
• Radarr/Sonarr Integration: Syncs and caches media metadata locally
• Trakt.tv Integration: Explore trending content and media metadata
• Tunarr Channels: Updates channel programming with curated content
• Cooldown Management: Prevents media from being replayed too frequently
• HTTP API Server: RESTful API with health checks and Prometheus metrics
• Cron Scheduler: Automated playlist generation on configurable schedules
• Kubernetes Ready: Comprehensive Helm charts for production deployment
• CLI & Server Modes: Run one-off generations or as a scheduled service

Workflow

1. Initial Sync: Run program-director sync to populate the database with your media
2. Configure Themes: Edit config.yaml with your Tunarr channel IDs and theme definitions
3. Generate Playlists: Run program-director generate --all-themes to create programming
4. Schedule Updates: Use program-director serve to run as a service with automatic scheduling
5. Monitor: Check logs and database for playlist history and cooldown tracking
