最近的项目中需要实现视频断点续播的功能,一听到这个功能。内心方张了..但却又有点小窃喜,小懵乱。抱着求学态度去挑战一下。

1.安装插件

npm install vue-video-player --save

2.Main.js 引入组件

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

3.页面使用组件

<el-tree :data="ChapterOptions"
     :props="defaultProps"
     node-key='id'
     highlight-current
     :filter-node-method="filterNode"
     ref="tree"
     default-expand-all
     @node-click="handleNodeClick" />
<video-player ref="videoPlayer"
        class="video-player vjs-custom-skin"
        style="width: 1000px;height: 576px;display: inline-flex"
        :playsinline="true"
        :options="playerOptions"
        @pause="onPlayerPause($event)"
        @ended="onPlayerEnded($event)"
        @play="onPlayerPlay($event)"
        @timeupdate="onPlayerTimeupdate($event)"
        @ready="playerReadied"
    />
<script>
import { videoPlayer } from 'vue-video-player'

  poster: '', // 你的封面地址
  width: document.documentElement.clientWidth, // 播放器宽度

  controlBar: {
   //当前时间和持续时间的分隔符
   timeDivider: true,
   //显示持续时间
   durationDisplay: true,
   //是否显示剩余时间功能
   remainingTimeDisplay: false,
   //全屏按钮
   fullscreenToggle: true
  }
  }
 };
},
computed: {
 player() {
  return this.$refs.videoPlayer.player//自定义播放
 }
 },
mounted () {
 this.timer = setInterval(this.putLearningObj, 3000)
 },
destroyed () {
 // 如果定时器在运行则关闭
 if (this.timer) {
  clearInterval(this.timer)
  }
 },
methods: {
 //用户信息
 getUser() {
  getUserProfile().then(response => {
  this.user = response.data;
  this.learningDuration.userId = this.user.userId
  });
 },
  //============================
 fullScreen() {
  const player = this.$refs.videoPlayer.player
  player.requestFullscreen()//调用全屏api方法
  player.isFullscreen(true)
  player.play()
 },
 onPlayerPlay(player) {
  this.paused = false
  // player.play()
 },
 onPlayerPause (player) {
  this.paused = true
  // console.log('onPlayerPause!', player)
 },
 onPlayerEnded (player) {
  this.paused = false;
  // clearInterval(this.timer);
 },
 //当前播放位置发生变化时触发。
 onPlayerTimeupdate (player) {
  // console.log(' onPlayerTimeupdate!', this.timeLog)
 },
 /* 设置视频进度 */
 playerReadied: function (player) {
 },
};
</script>

上面的 src视频地址可以换成具体的地址串,也能换成后台的地址串,因为我的是章节树所以我和章节id进行了关联

 /** 查询部门下拉树结构 */
 getTreeselect() {
  treeselect().then((response) => {
  //封面
  var img = '';
  this.ChapterOptions = response.data;
  for (let i = 0; i <this.ChapterOptions.length ; i++) {
   this.videoName = this.ChapterOptions[0].children[0].chapterName
   this.videoIntroduce = this.ChapterOptions[0].children[0].chapterIntroduce
   this.VideoUrl = JSON.parse(this.ChapterOptions[0].children[0].videoAddress)
   img = JSON.parse(this.ChapterOptions[0].children[0].imageAddress)
   //初始化封面
   for (let j = 0; j <img.length ; j++) {
   this.playerOptions.poster =img[0];
   }
   //初始化第一个章节视频
   for (let j = 0; j <this.VideoUrl.length ; j++) {
   this.playerOptions.sources[0].src = this.VideoUrl[0]
   }
   //初始化章节
   this.learningDuration.chapterId = this.ChapterOptions[0].children[0].id;
   //默认高亮第一个章节节点
   this.$nextTick(()=>{
   this.$refs.tree.setCurrentKey(this.ChapterOptions[0].children[0].id);
   })
  }
  });
 },
 // 筛选节点
 filterNode(value, data) {
  if (!value) return true;
  return data.label.indexOf(value) !== -1;
 },
 // 节点单击事件
 handleNodeClick(data) {
  // console.log(data)
  var img = '';
  //刷新原视频, 原封面
  this.playerOptions.sources[0].src = '';
  this.playerOptions.poster = '';
  //转换视频
  this.VideoUrl= JSON.parse(data.videoAddress);
  // console.log("this.VideoUrl")
  for (let i = 0; i <this.VideoUrl.length ; i++) {
  this.playerOptions.sources[0].src = this.VideoUrl[0];
  }
  img = JSON.parse(data.imageAddress);
  for (let i = 0; i <img.length ; i++) {
  this.playerOptions.poster = img[0];
  }
  // console.log("this.playerOptions.sources[0].src")
  // console.log(this.playerOptions.sources[0].src)
  //章节介绍
  this.videoIntroduce = data.chapterIntroduce;
  //章节名称
  this.videoName = data.chapterName;
  //章节id
  this.learningDuration.chapterId = data.id
  // console.log(this.videoIntroduce)
 },

4.进度保存

接下来就是 保存视频的进度条了,通过打印发现onPlayerTimeupdate可获取到视频的进度,故采用定时器 每3秒触发一次数据交互

computed: {
 player() {
  return this.$refs.videoPlayer.player//自定义播放
 }
 },
 mounted () {
 this.timer = setInterval(this.putLearningObj, 3000)
 },
 destroyed () {
 // 如果定时器在运行则关闭
 if (this.timer) {
  clearInterval(this.timer)
  }
 },
methods: {  
putLearningObj () {
  if (!this.paused) {
  //保存视频进度
  saveTime(this.learningDuration)
  console.log('putLearningObj ~~~~~~~~~')
  }
 },
//当前播放位置发生变化时触发。
onPlayerTimeupdate (player) {
 this.learningDuration.timeLog = player.cache_.currentTime
  // console.log(' onPlayerTimeupdate!', this.timeLog)
 },
},

saveTime是我自定义的与后端交互的方法。(可自行定义)

// 保存视频进度
export function saveTime(data) {
 return request({
 url: '/***/****/***/',
 method: 'put',
 data: data
 })
}

那么到了这一步 进度就能保存下来了

4.进度恢复

想要恢复进度,就必须在视频播放前把 保存进度下来的设置到视频当中,通过打印可以看出playerReadied 可以设置

/* 设置视频进度 */
playerReadied: function (player) {
//可在此调用后台交互方法
...
player.currentTime(this.learningDuration.timeLog)
},

到此 进度可以 恢复了 大功告成!。至于后台交互数据 需求不一样,代码也就没有贴出来。
