这次给大家带来怎样使用Vue结合Video.js播放m3u8视频，使用Vue结合Video.js播放m3u8视频的注意事项有哪些，下面就是实战案例，一起来看一下。

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

完成测试代码
