使用uniapp开发的项目视频监控播放页面，要求播放hls.m3u8的视频流。
"http://192.168.1.1:90/rtp/45010/hls.m3u8"
安装依赖
"mux.js": "^6.2.0",
"video.js": "^8.0.3",
"videojs-contrib-hls": "^5.15.0"
cnpm i mux.js video.js videojs-contrib-hls --save
需要安装mux.js，否则会报文件查找失败：'mux.js/lib/tools/parse-sidx' at node_modules/_video.js@8.0.3@video.js/dist/video.es.js:1的错误。
main.js 引入依赖
import Videojs from 'video.js'
import 'video.js/dist/video-js.min.css'
Vue.prototype.$video = Videojs
播放页面引入
