在vue项目中如何获取视频的时长

vue获取视频时长

传入参数为视频文件对象

js的代码如下：

getVideoDuration(file) {
 var url = URL.createObjectURL(file);
 var audioElement = new Audio(url);
 var self = this;
 var result;
 audioElement.addEventListener("loadedmetadata", function() {
  // 视频时长值的获取要等到这个匿名函数执行完毕才产生
  result = audioElement.duration; //得到时长为秒，小数，182.36
  self.ruleForm.videoDuration = parseInt(result); //转为int值
 });
}

vue-video-player获取播放时间

npm install vue-video-player -S

全局引用

import VideoPlayer from 'vue-video-player'
import 'vue-video-player/src/custom-theme.css'
import 'video.js/dist/video-js.css'
Vue.use(VideoPlayer)

局部引用

 import {
  videoPlayer
 } from 'vue-video-player'
 import 'video.js/dist/video-js.css'
 export default {
 components: {
  videoPlayer
 }
}

html

 <video-player class="video-player vjs-custom-skin"
      ref="videoPlayer"
      :playsinline="true"
      :options="playerOptions">
   </video-player>

methods 获取播放时间

 this.$nextTick(() => {
   setTimeout(() => {
   let du = document.getElementById("vjs_video_3_html5_api") //获取组件下的video
   var hour = parseInt((du.duration) / 3600);
   var minute = parseInt((du.duration % 3600) / 60);
   var second = parseInt(du.duration % 60);
   let result = ''
   if (hour > 0) {
   result = this.formatTimeStr(hour) + ':' + this.formatTimeStr(minute) + ':' + this
   .formatTimeStr(second)
        } else {
          result = this.formatTimeStr(minute) + ':' +
         this.formatTimeStr(second)
         }
         return result //转化成分，秒
        }, 200)
       })

  formatTimeStr(val) {
    if (val > 9) {
     return val
    } else {
     return '0' + val
    }
   },
