首先，我們需要在vue工程中安裝video.js相關依賴。
npm install --save video.js npm install --save videojs-contrib-hls
然后，我們需要引入videojs的css文件，例如在main.js中引入
import 'video.js/dist/video-js.css'
接著，我們在需要播放視頻的頁面引入js對象
import videojs from 'video.js' import 'videojs-contrib-hls'
指定一個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，我們在mounted節點初始化播放器：
videojs('my-video', {
bigPlayButton: false,
textTrackDisplay: false,
posterImage: true,
errorDisplay: false,
controlBar: true
}, function () {
this.play()
})
Video.js中m3u8視頻清晰度切換
