Live777

A real-time audio and video streaming media server

---

Live777 is a very simple, high performance, lightweight WebRTC SFU (Selective Forwarding Unit) server, with WHIP/WHEP as its first-class protocols.

Live777 works with GStreamer, FFmpeg, OBS Studio, VLC, WebRTC and other clients to receive and distribute streams — a typical publish (push) / subscribe (play) server model. It also converts between the audio and video protocols widely used on the Internet, such as RTP/RTSP to WHIP and WHEP.

Features

• 📚 Support WHIP/WHEP

  Implements the WHIP/WHEP protocols for out-of-the-box interoperability with other WebRTC application modules — no custom adaptation required.

• 🗃️ P2P/SFU Mix architecture

  Only forwards media streams — no mixing, transcoding or other resource-hungry media processing on the server. Encoding and decoding stay on the sender and the receiver respectively.

• 🌐 Multiple platform support

  Native support for Linux, macOS, Windows and Android, on both ARM and x86.

• 🕸️ Cluster & cascade

  The companion liveman manager turns multiple Live777 nodes into a cluster — proxying client requests, managing cascade state between nodes, and coordinating recording across the cluster.

• 🎥 Stream recording

  Record published streams as fragmented MP4 segments to the local filesystem or S3-compatible object storage, controlled through the REST API.

• 📊 WebUI & observability

  An embedded WebUI, admin and session REST APIs, and Prometheus metrics are built in for easy operation and observability in production.

Quick Start

Run Live777 with Docker (host networking is required):

docker run --name live777-server --rm --network host ghcr.io/binbat/live777-server:latest live777

Then open your browser at http://localhost:7777/.

For prebuilt binaries, Linux packages, winget and cargo installs, see the installation guide.
