StableAvatar

🎬 Infinite-Length Audio-Driven Avatar Video Generation - Generate high-quality talking head videos from a single image and audio input.

Based on StableAvatar research paper, this project provides a production-ready Docker deployment with Web UI, REST API, and MCP server support.

✨ Features

• 🖼️ Single Image Input - Generate videos from just one reference image
• 🎵 Audio-Driven - Lip-sync animation driven by any audio input
• ♾️ Infinite Length - Generate videos of any duration without quality degradation
• 🎯 Identity Preserving - Maintains facial identity throughout the video
• 🌐 Web UI - User-friendly interface with real-time GPU monitoring
• 🔌 REST API - Full-featured API with Swagger documentation
• 🤖 MCP Server - Claude Desktop integration support
• 🐳 Docker Ready - One-command deployment with all dependencies
