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。
npm install VUE-video-player --save
import VideoPlayer from 'Vue-video-player' reqUIre('video.JS/dist/video-js.CSS') require('vue-video-player/src/custom-theme.css') Vue.use(VideoPlayer)
页面中应用。
<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' import 'video.js/dist/video-js.css' import 'vue-video-player/src/custom-theme.css' import { treeselect } from "@/API//driver/videoChapter"; import Treeselect from "@riophae/vue-treeselect"; import "@riophae/vue-treeselect/dist/vue-treeselect.css"; Export default { name: "videoPlayer", components: { Treeselect,videoPlayer }, data() { return { //用户信息 user:{}, //=============================== paused: true, learningDuration: { userId: '', //用户id chapterId:'',//章节id timeLog: '', //视频观看时长 }, playerOptions: { playbackRates: [0.5, 1.0, 1.5, 2.0], //播放速度 autoplay: false, // 如果true,浏览器准备好时开始回放。 muted: false, // 默认情况下将会消除任何音频。 loop: false, // 导致视频一结束就重新开始。 PReload: 'auto', // 建议浏览器在<video>加载元素后是否应该开始下载视频数据。auto浏览器选择最佳行为,立即开始加载视频（如果浏览器支持） language: 'zh-CN', aspectRatio: '16:9', // 将播放器置于流畅模式，并在计算播放器的动态大小时使用该值。值应该代表一个比例 - 用冒号分隔的两个数字（例如"16:9"或"4:3"） fluid: true, // 当true时，Video.js player将拥有流体大小。换句话说，它将按比例缩放以适应其容器。 sources: [ { type: 'video/mp4', // 这里的种类支持很多种：基本视频格式、直播、流媒体等，具体可以参看git网址项目 src: ''// url地址 } ], hls: true, poster: '', // 你的封面地址 width: document.documentElement.clIEntWidth, // 播放器宽度 notSupportedMessage: '此视频暂无法播放，请稍后再试', // 允许覆盖Video.js无法播放媒体源时显示的默认信息。 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)
},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
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)
},
