SyncTV

简体中文

SyncTV is a Rust implementation of a real-time synchronized video watching platform with media provider integration, livestreaming, HTTP/gRPC APIs, and Kubernetes-ready horizontal scaling.

Highlights

• Synchronized room playback with real-time state updates.
• Media providers including Bilibili, Alist, Emby, Jellyfin, and direct URLs.
• RTMP push/pull, HLS, and HTTP-FLV livestream support.
• HTTP REST, public gRPC, WebSocket, management gRPC, metrics, RTMP, and STUN runtime surfaces.
• PostgreSQL-backed durable storage with optional Redis shared state, cache, rate limiting, and cluster coordination.
• Docker Compose and Helm deployment templates.
• Built-in management CLI and optional OpenAPI/Swagger UI.
• Astro Starlight documentation site with English and Simplified Chinese content.

Quick Start

Development environment:

docker compose -f docker-compose.dev.yml up -d

Production Compose requires explicit secrets:

export SYNCTV_JWT_SECRET="$(openssl rand -base64 32)"
export SYNCTV_SECURITY_CREDENTIAL_ENCRYPTION_KEY="$(openssl rand -hex 32)"
export SYNCTV_SECURITY_OPAQUE_SERVER_SETUP_SECRET="$(openssl rand -base64 48)"
export SYNCTV_BOOTSTRAP_ROOT_PASSWORD="replace-with-a-strong-password"

docker compose up -d

Validate configuration:

cargo run -p synctv --bin synctv -- config validate

Optional migration preflight. The server also runs embedded SQLx migrations automatically during startup:

cargo run -p synctv --bin synctv -- db migrate

Start locally:

cargo run -p synctv --bin synctv -- serve

Documentation

The main documentation site lives in docs/. It contains detailed configuration reference, deployment guides, operations runbooks, CLI reference, development guide, and OpenAPI access instructions.

cd docs
npm install
npm run dev

Build the static docs site:

cd docs
npm run build

If the generated site is deployed below a subpath, set SYNCTV_DOCS_BASE at build time. Set SYNCTV_DOCS_SITE to the public origin used for canonical URLs and sitemaps.

cd docs
SYNCTV_DOCS_SITE=https://example.com SYNCTV_DOCS_BASE=/synctv npm run build
