SRT Library

Introduction

SRT (Secure Reliable Transport) delivers broadcast-quality video over unpredictable networks. Originally developed by Haivision and now an open standard, SRT combines ultra-low latency with robust error correction — making it the protocol of choice for live contribution, remote production, and real-time streaming.

VASTreaming's SRT library provides caller, listener, and rendezvous modes for maximum deployment flexibility.

Ultra-Low Latency

SRT achieves what other protocols can't: reliable delivery with minimal delay.

Perfect for drone piloting, live auctions, remote camera control, and any application where milliseconds matter.

Publishing

Push live streams from any source — cameras, microphones, screen capture — to SRT listeners. Mix multiple video and audio sources with our video and audio processing capabilities.

SRT's caller/listener model lets you push through firewalls without port forwarding on the sender side.

Playback

Receive SRT streams with hardware-accelerated decoding and rendering. Drop-in UI controls for all platforms. See our Playback Library for rendering options.

Server

Build SRT servers that accept multiple callers and redistribute streams. Handle hundreds of simultaneous connections with efficient resource usage.

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