這篇文章主要介紹了vue-video-player 斷點(diǎn)續(xù)播的實(shí)現(xiàn),本文給大家介紹的非常詳細(xì)，對(duì)大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值，需要的朋友可以參考下

最近的項(xiàng)目中需要實(shí)現(xiàn)視頻斷點(diǎn)續(xù)播的功能，一聽(tīng)到這個(gè)功能。內(nèi)心方張了..但卻又有點(diǎn)小竊喜，小懵亂。抱著求學(xué)態(tài)度去挑戰(zhàn)一下。

1.安裝插件

npm install vue-video-player --save

2.Main.js 引入組件

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.頁(yè)面使用組件

<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"
    />

上面的 src視頻地址可以換成具體的地址串,也能換成后臺(tái)的地址串，因?yàn)槲业氖钦鹿?jié)樹(shù)所以我和章節(jié)id進(jìn)行了關(guān)聯(lián)

 /** 查詢(xún)部門(mén)下拉樹(shù)結(jié)構(gòu) */
 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];
   }
   //初始化第一個(gè)章節(jié)視頻
   for (let j = 0; j <this.VideoUrl.length ; j++) {
   this.playerOptions.sources[0].src = this.VideoUrl[0]
   }
   //初始化章節(jié)
   this.learningDuration.chapterId = this.ChapterOptions[0].children[0].id;
   //默認(rèn)高亮第一個(gè)章節(jié)節(jié)點(diǎn)
   this.$nextTick(()=>{
   this.$refs.tree.setCurrentKey(this.ChapterOptions[0].children[0].id);
   })
  }
  });
 },
 // 篩選節(jié)點(diǎn)
 filterNode(value, data) {
  if (!value) return true;
  return data.label.indexOf(value) !== -1;
 },
 // 節(jié)點(diǎn)單擊事件
 handleNodeClick(data) {
  // console.log(data)
  var img = '';
  //刷新原視頻, 原封面
  this.playerOptions.sources[0].src = '';
  this.playerOptions.poster = '';
  //轉(zhuǎn)換視頻
  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)
  //章節(jié)介紹
  this.videoIntroduce = data.chapterIntroduce;
  //章節(jié)名稱(chēng)
  this.videoName = data.chapterName;
  //章節(jié)id
  this.learningDuration.chapterId = data.id
  // console.log(this.videoIntroduce)
 },

4.進(jìn)度保存

接下來(lái)就是保存視頻的進(jìn)度條了，通過(guò)打印發(fā)現(xiàn)onPlayerTimeupdate可獲取到視頻的進(jìn)度，故采用定時(shí)器每3秒觸發(fā)一次數(shù)據(jù)交互

computed: {
 player() {
  return this.$refs.videoPlayer.player//自定義播放
 }
 },
 mounted () {
 this.timer = setInterval(this.putLearningObj, 3000)
 },
 destroyed () {
 // 如果定時(shí)器在運(yùn)行則關(guān)閉
 if (this.timer) {
  clearInterval(this.timer)
  }
 },
methods: {  
putLearningObj () {
  if (!this.paused) {
  //保存視頻進(jìn)度
  saveTime(this.learningDuration)
  console.log('putLearningObj ~~~~~~~~~')
  }
 },
//當(dāng)前播放位置發(fā)生變化時(shí)觸發(fā)。
onPlayerTimeupdate (player) {
 this.learningDuration.timeLog = player.cache_.currentTime
  // console.log(' onPlayerTimeupdate!', this.timeLog)
 },
},

saveTime是我自定義的與后端交互的方法。（可自行定義）

// 保存視頻進(jìn)度
export function saveTime(data) {
 return request({
 url: '/***/****/***/',
 method: 'put',
 data: data
 })
}

那么到了這一步進(jìn)度就能保存下來(lái)了

4.進(jìn)度恢復(fù)

想要恢復(fù)進(jìn)度，就必須在視頻播放前把保存進(jìn)度下來(lái)的設(shè)置到視頻當(dāng)中，通過(guò)打印可以看出playerReadied 可以設(shè)置

/* 設(shè)置視頻進(jìn)度 */
playerReadied: function (player) {
//可在此調(diào)用后臺(tái)交互方法
...
player.currentTime(this.learningDuration.timeLog)
},

到此進(jìn)度可以恢復(fù)了大功告成！。至于后臺(tái)交互數(shù)據(jù) 需求不一樣，代碼也就沒(méi)有貼出來(lái)。
