Golang 实现 MP4 视频文件服务器

生命不止,继续 go go go !!!

有点忙,有点懈怠,继续。

关于golang实现的静态文件服务器之前有写过

Go实战golang实现静态文件服务器(文件查看,文件上传,文件下载)

正好最近在做视频方面的东西那么先来个简单的实现一个提供mp4视频文件的服务器吧并且通过浏览器访问播放。

MP4 文件服务器

package main

import (
    "log"
    "net/http"
    "os"
    "time"
)

func ServeHTTP(w http.ResponseWriter, r *http.Request) {
    video, err := os.Open("./test.mp4")
    if err != nil {
        log.Fatal(err)
    }
    defer video.Close()

    http.ServeContent(w, r, "test.mp4", time.Now(), video)
}

func main() {
    http.HandleFunc("/", ServeHTTP)
    http.ListenAndServe(":8080", nil)
}
package main

import "os"
import "log"
import "net/http"
import "strings"

type viewHandler struct{}

func (vh *viewHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) {
    path := r.URL.Path[1:]

    data, err := os.ReadFile(string(path))

    if err != nil {
        log.Printf("Error with path %s: %v", path, err)
        w.WriteHeader(404)
        w.Write([]byte("404"))
    }

    if strings.HasSuffix(path, ".html") {
        w.Header().Add("Content-Type", "text/html")
    } else if strings.HasSuffix(path, ".mp4") {
        w.Header().Add("Content-Type", "video/mp4")
    }

    w.Write(data)
}

func main() {
    http.Handle("/", new(viewHandler))
    http.ListenAndServe(":8080", nil)
}

Golang audio/video library and streaming server

我们先浅尝辄止,简单使用一下:

package main

import (
    "fmt"

    "github.com/nareix/joy4/av"
    "github.com/nareix/joy4/av/avutil"
    "github.com/nareix/joy4/format"
)

func init() {
    format.RegisterAll()
}

func main() {
    file, _ := avutil.Open("test.mp4")
    streams, _ := file.Streams()
    for _, stream := range streams {
        if stream.Type().IsAudio() {
            astream := stream.(av.AudioCodecData)
            fmt.Println(astream.Type(), astream.SampleRate(), astream.SampleFormat(), astream.ChannelLayout())
        } else if stream.Type().IsVideo() {
            vstream := stream.(av.VideoCodecData)
            fmt.Println(vstream.Type(), vstream.Width(), vstream.Height())
        }
    }

    file.Close()
}

以上程序输出:

AAC 48000 FLTP 1ch
H264 960 720
