This repository is a full-stack self-hosted media download manager and library preparation layer centered on yt-dlp. The backend is implemented in Python using aiohttp, SQLite (via SQLAlchemy), and includes a structured feature-based architecture (auth, presets, tasks, conditions, downloads, streaming, notifications, ytdlp integration). The frontend is a Nuxt 3 / Vue 3 single-page application with comprehensive i18n support. Core capabilities include automated download scheduling with cron-like task definitions, conditional filtering, Cloudflare challenge solving, real-time WebSocket updates, streaming via on-the-fly HLS transcoding with hardware acceleration fallback, and a browser extension for quick URL submission. The codebase demonstrates good engineering practices: event bus for decoupled communication, singleton-based service containers, repository pattern for data access, custom migration framework, and extensive async test coverage. Notable external dependencies are yt-dlp (core downloader), ffmpeg (transcoding), curl_cffi (impersonation), and apprise (notifications). While the architecture is modular and well-organized, there is some code duplication across CRUD repositories and migration files, and tight coupling to yt-dlp internals via custom patches. The project is actively maintained with frequent commits, a large test suite, and clear containerization support.
