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:
