首先，我们需要在vue工程中安装video.js相关依赖。
npm install --save video.js
npm install --save videojs-contrib-hls然后，我们需要引入videojs的css文件，例如在main.js中引入
import 'video.js/dist/video-js.css'接着，我们在需要播放视频的页面引入js对象
import videojs from 'video.js'
import 'videojs-contrib-hls'指定一个video容器，例如：
<video id="my-video" class="video-js vjs-default-skin" controls preload="auto" poster="../assets/video.png">
<source src="http://127.0.0.1:7086/aaa/213/stream/1.m3u8" type="application/x-mpegURL">
</video>最后，我们在mounted节点初始化播放器：
videojs('my-video', {
bigPlayButton: false,
textTrackDisplay: false,
posterImage: true,
errorDisplay: false,
controlBar: true
}, function () {
this.play()
})Video.js中m3u8视频清晰度切换
