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 mainimport ( "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)}

nareix/joy4
Golang audio/video library and streaming server
我们先浅尝辄止，简单使用一下：
package mainimport ( "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()}
