## What it is
SyncTV is a self-hosted Rust server for real-time synchronized video watching with rooms, chat, and livestreaming (RTMP/HLS/HTTP-FLV/RTSP). It integrates many media providers (YouTube, Bilibili, Twitch, Emby/Jellyfin, NAS platforms) and exposes HTTP REST, gRPC, WebSocket, and OpenAPI interfaces with Docker Compose and Helm deployment options.

## Use cases
- host a synchronized movie night with friends online
- watch youtube videos together in sync
- self-host a watch-together server with chat
- stream a live event to a synced viewing room
- play videos from my emby or jellyfin library in a shared room
- build a custom client for a synced video platform
- deploy a scalable watch-party service on kubernetes

## When to choose
- you want self-hosted synchronized viewing with broad media provider support
- you need livestream ingestion (RTMP/RTSP) alongside watch-together rooms
- you need HTTP, gRPC, and WebSocket APIs to build custom clients
- you need horizontal scaling with PostgreSQL, Redis, and Kubernetes/Helm deployment

## When to avoid
- you just want a simple peer-to-peer watch party without running a server
- you need video transcoding or a full media library manager rather than playback orchestration
- you want a fully managed hosted service with no deployment work
