vue-video-player 斷點續播的實現

最近的項目中需要實現視頻斷點續播的功能,一聽到這個功能。內心方張瞭..但卻又有點小竊喜,小懵亂。抱著求學態度去挑戰一下。

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"
    />
<script>
import { videoPlayer } from 'vue-video-player'

 data() {
 return {
  //用戶信息
  user:{},
  //===============================
  paused: true,
  learningDuration: {
  userId: '', //用戶id
  chapterId:'',//章節id
  timeLog: '', //視頻觀看時長

  fluid: true, // 當true時,Video.js player將擁有流體大小。換句話說,它將按比例縮放以適應其容器。
  sources: [
   {
   type: 'video/mp4', // 這裡的種類支持很多種:基本視頻格式、直播、流媒體等,具體可以參看git網址項目
   src: ''// url地址
   }
  ],
  hls: true,
  poster: '', // 你的封面地址

   //顯示持續時間
   durationDisplay: true,
   //是否顯示剩餘時間功能
   remainingTimeDisplay: false,
   //全屏按鈕
   fullscreenToggle: true
  }
  }
 };
},
computed: {
 player() {
  return this.$refs.videoPlayer.player//自定義播放
 }
 },
mounted () {
 this.timer = setInterval(this.putLearningObj, 3000)
 },
destroyed () {
 // 如果定時器在運行則關閉
 if (this.timer) {
  clearInterval(this.timer)
  }
 },
methods: {
 //用戶信息
 getUser() {
  getUserProfile().then(response => {
  this.user = response.data;
  this.learningDuration.userId = this.user.userId
  });
 },
  //============================
 fullScreen() {
  const player = this.$refs.videoPlayer.player
  player.requestFullscreen()//調用全屏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);
 },
 //當前播放位置發生變化時觸發。
 onPlayerTimeupdate (player) {
  // console.log(' onPlayerTimeupdate!', this.timeLog)
 },
 /* 設置視頻進度 */
 playerReadied: function (player) {
 },
};
</script>

上面的 src視頻地址可以換成具體的地址串,也能換成後臺的地址串,因為我的是章節樹所以我和章節id進行瞭關聯

 /** 查詢部門下拉樹結構 */
 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];
   }
   //初始化第一個章節視頻
   for (let j = 0; j <this.VideoUrl.length ; j++) {
   this.playerOptions.sources[0].src = this.VideoUrl[0]
   }
   //初始化章節
   this.learningDuration.chapterId = this.ChapterOptions[0].children[0].id;
   //默認高亮第一個章節節點
   this.$nextTick(()=>{
   this.$refs.tree.setCurrentKey(this.ChapterOptions[0].children[0].id);
   })
  }
  });
 },
 // 篩選節點
 filterNode(value, data) {
  if (!value) return true;
  return data.label.indexOf(value) !== -1;
 },
 // 節點單擊事件
 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)
  //章節介紹
  this.videoIntroduce = data.chapterIntroduce;
  //章節名稱
  this.videoName = data.chapterName;
  //章節id
  this.learningDuration.chapterId = data.id
  // console.log(this.videoIntroduce)
 },

4.進度保存

接下來就是 保存視頻的進度條瞭,通過打印發現onPlayerTimeupdate可獲取到視頻的進度,故采用定時器 每3秒觸發一次數據交互

computed: {
 player() {
  return this.$refs.videoPlayer.player//自定義播放
 }
 },
 mounted () {
 this.timer = setInterval(this.putLearningObj, 3000)
 },
 destroyed () {
 // 如果定時器在運行則關閉
 if (this.timer) {
  clearInterval(this.timer)
  }
 },
methods: {  
putLearningObj () {
  if (!this.paused) {
  //保存視頻進度
  saveTime(this.learningDuration)
  console.log('putLearningObj ~~~~~~~~~')
  }
 },
//當前播放位置發生變化時觸發。
onPlayerTimeupdate (player) {
 this.learningDuration.timeLog = player.cache_.currentTime
  // console.log(' onPlayerTimeupdate!', this.timeLog)
 },
},

saveTime是我自定義的與後端交互的方法。(可自行定義)

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

那麼到瞭這一步 進度就能保存下來瞭

4.進度恢復

想要恢復進度,就必須在視頻播放前把 保存進度下來的設置到視頻當中,通過打印可以看出playerReadied 可以設置

/* 設置視頻進度 */
playerReadied: function (player) {
//可在此調用後臺交互方法
...
player.currentTime(this.learningDuration.timeLog)
},

到此 進度可以 恢復瞭 大功告成!。至於後臺交互數據 需求不一樣,代碼也就沒有貼出來。
