Which golang framework is most suitable for developing real-time streaming applications?

Choose the ideal Golang framework for your live streaming application: Janus Gateway: Scalable and reliable large-scale streaming application. Red5 Pro: Commercial server that supports low latency, high throughput and multiple codecs. Livekit: an open source engine with low latency and high scalability, suitable for interactive streaming applications.

Choose the ideal Golang framework for your live streaming application

When building a live streaming application, choose the right framework to It's important. Golang provides several excellent frameworks, each with its own advantages and disadvantages. This article will explore the Golang framework most suitable for live streaming applications and provide practical examples.

The most suitable Golang framework for real-time streaming applications

• Janus Gateway: Janus Gateway is a real-time streaming server that supports Multiple protocols including WebRTC, RTMP and SIP. Its scalability and reliability make it ideal for building large-scale streaming applications.
• Red5 Pro: Red5 Pro is a commercial live streaming server that provides enterprise-grade features such as low latency, high throughput and support for multiple video codecs and containers support.
• Livekit: Livekit is an open source live streaming engine with extremely low latency and high scalability. It is easy to install and integrate, making it ideal for building streaming applications with interactive capabilities.

Practical case

Build a real-time video conferencing application using Janus Gateway

Let us write a simple Golang Program to build a real-time video conferencing application using Janus Gateway:

import (
    "github.com/gortc/janus"
)

func main() {
    // 创建一个 Janus Gateway 客户端
    client, err := janus.NewClient("ws://localhost:8188/janus")
    if err != nil {
        log.Fatal(err)
    }
    
    // 加入一个会议室
    room, err := client.Attach("janus.plugin.videoroom")
    if err != nil {
        log.Fatal(err)
    }
    
    // 发送音视频数据
    encoderOpus := new(janus.OpusEncoder)
    encoderVp8 := new(janus.Vp8Encoder)
    session, err := room.NewHandle()
    if err != nil {
        log.Fatal(err)
    }
    go func() {
        defer session.Stop()
        for {
            // 捕获音频和视频数据
            audioData := getAudioData()
            videoData := getVideoData()
            
            // 编码数据
            opusData, err := encoderOpus.Encode(audioData)
            if err != nil {
                log.Fatal(err)
            }
            vp8Data, err := encoderVp8.Encode(videoData)
            if err != nil {
                log.Fatal(err)
            }
            
            // 发送数据到会议室
            session.Send(janus.AudioOPUS{Data: opusData})
            session.Send(janus.VideoVP8{Data: vp8Data})
        }
    }()

    // 主循环
    for {
        // 接收数据并解码
        msg, _, err := session.Read()
        if err != nil {
            log.Fatal(err)
        }
        switch msg.(type) {
        case *janus.AudioOPUS:
            // 解码和播放音频数据
        case *janus.VideoVP8:
            // 解码和显示视频数据
        }
    }
}
