srtgo

Go bindings for SRT (Secure Reliable Transport), the open source transport technology that optimizes streaming performance across unpredictable networks.

Why srtgo?

The purpose of srtgo is easing the adoption of SRT transport technology. Using Go, with just a few lines of code you can implement an application that sends/receives data with all the benefits of SRT technology: security and reliability, while keeping latency low.

Is this a new implementation of SRT?

No! We are just exposing the great work done by the community in the SRT project as a golang library. All the functionality and implementation still resides in the official SRT project.

Features supported

Basic API exposed to easy develop SRT sender/receiver apps
Caller and Listener mode
Live transport type
File transport type
Message/Buffer API
SRT transport options up to SRT 1.4.1
SRT Stats retrieval

Usage

Example of a SRT receiver application:

package main

import (
    "github.com/haivision/srtgo"
    "fmt"
)

func main() {
    options := make(map[string]string)
    options["transtype"] = "file"

    sck := srtgo.NewSrtSocket("0.0.0.0", 8090, options)
    defer sck.Close()
    sck.Listen(1)
    s, _ := sck.Accept()
    defer s.Close()

    buf := make([]byte, 2048)
    for {
        n, _ := s.Read(buf)
        if n == 0 {
            break
        }
        fmt.Println("Received %d bytes", n)
    }
    //....
}
