Design Goals

mediasoup and its client side libraries are designed to accomplish with the following goals:

• Be a SFU (Selective Forwarding Unit).
• Support both WebRTC and plain RTP input and output.
• Be a Node.js module or Rust crate in server side.
• Be a tiny TypeScript and C++ libraries in client side.
• Be minimalist: just handle the media layer.
• Be signaling agnostic: do not mandate any signaling protocol.
• Be super low level API.
• Support all existing WebRTC endpoints.
• Enable integration with well known multimedia libraries/tools.

Architecture

Use Cases

mediasoup and its client side libraries provide a super low level API. They are intended to enable different use cases and scenarios, without any constraint or assumption. Some of these use cases are:

• Group video chat applications.
• One-to-many (or few-to-many) broadcasting applications in real-time.
• RTP streaming.

Features

• ECMAScript 6/Idiomatic Rust low level API.
• Multi-stream: multiple audio/video streams over a single ICE + DTLS transport.
• IPv6 ready.
• ICE / DTLS / RTP / RTCP over UDP and TCP.
• Simulcast and SVC support.
• Congestion control.
• Sender and receiver bandwidth estimation with spatial/temporal layers distribution algorithm.
• Data message exchange (via WebRTC DataChannels, SCTP over plain UDP, and direct termination in Node.js/Rust).
• Extremely powerful (media worker thread/subprocess coded in C++ on top of libuv).
