RTMP Library

Introduction

RTMP remains the universal language for live streaming. YouTube, Facebook, Twitch, and virtually every major platform use RTMP for stream ingestion. While the protocol originated in the Flash era, its publishing capability — pushing live streams from client to server — keeps it essential today.

VASTreaming's RTMP library gives you complete control: publish streams to any server, play streams on any device, or build your own RTMP server.

Publishing

Stream from any source — cameras, microphones, screen capture — to any RTMP server. Mix multiple video and audio sources into a single broadcast with our video and audio processing capabilities.

Tested and proven with Wowza, Red5, Azure Media Services, and dozens of other RTMP servers. If you encounter compatibility issues, we'll provide a fix.

Playback

Play RTMP streams with 200-300ms latency — critical for surveillance, video chat, and game streaming. Drop-in UI controls for all platforms make integration straightforward. See our Playback Library for hardware-accelerated rendering options.

Server

Build RTMP servers that ingest and redistribute streams. From simple two-way communication between devices to high-capacity servers handling thousands of connections.

For multi-protocol servers supporting RTMP, RTSP, HLS, WebRTC and more, see our Streaming Server Library.
