说明

gmp4

gmp4是一个能够通过视频的url\本地路径获取其时长的轻量级库，目前仅支持MP4格式的视频

安装

go get -u github.com/Stitch-Zhang/gmp4

使用

获取网络资源中MP4视频时长

https://www.runoob.com/try/demo_source/movie.mp4

Example

package main

import (
	"fmt"
	"github.com/Stitch-Zhang/gmp4"
)

func main() {
	video, err := gmp4.NewRemote("https://www.runoob.com/try/demo_source/movie.mp4")
	if err != nil {
		fmt.Println("获取失败:", err)
		return
	}
	videoTime := gmp4.GetDuration(video)
	fmt.Printf("获取成功，时长=%ds", videoTime)
}

///获取成功，时长=:12s

设置请求头

···
    video, err := gmp4.NewRemote("https://www.runoob.com/try/demo_source/movie.mp4")
	if err != nil {
		fmt.Println("获取失败:", err)
		return
    }
    header :=http.Header{
	    "User-Agent": {"Mozilla/5.0 (Windows NT 10.0; x64; rv:85.0) Gecko/20100101 Firefox/85.0"},
		///Key,Value 有两种方式存放
		///方法1
		"Cookie": {"cookie1_key=cookie1_value","cookie2_key=cookie2_value"},
		///方法2
		"Cookie": {"cookie1_key=cookie1_value;cookie2_key=cookie2_value"}
	}
	video.SetHeader(header)
···

设置请求超时

···
    video, err := gmp4.NewRemote("https://www.runoob.com/try/demo_source/movie.mp4")
	if err != nil {
		fmt.Println("获取失败:", err)
		return
    }
    video.SetTimeout(3*time.Second)

···

获取本地MP4视频时长

文件路径:C:\demo.mp4

package main

import (
	"fmt"
	"github.com/Stitch-Zhang/gmp4"
)

func main() {
	video, err := gmp4.NewLocal(`C:\demo.mp4`)
	if err != nil {
		fmt.Println("获取失败:", err)
		return
	}
	videoTime := gmp4.GetDuration(video)
	fmt.Printf("获取成功，时长=%ds", videoTime)
}

///获取成功，时长=:2233s
