# srtgo
|
||
|
|
|
||
|
|
Go bindings for [SRT](https://github.com/Haivision/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](https://github.com/Haivision/srt) as a golang library. All the functionality and implementation still resides in the official SRT project.

# Usage
|
||
|
|
Example of a SRT receiver application:
|
||
|
|
``` go
|
||
|
|
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)
|
||
|
|
}
|
||
|
|
//....
|
||
|
|
}
|
||
|
|
|
