### 安装 ###

npm install video.js --save

### 组件内导入 ###

需要同时导入videoJS以及相关的CSS

import videojs from "video.js"
    import "video.js/dist/video-js.css"

### 组件内使用 ###

import {
         onUnmounted, ref, nextTick } from "vue"
    import videojs from "video.js"
    import "video.js/dist/video-js.css"
    const videoPlayer = ref(null)
    const myPlayer = ref(null)
    nextTick(() => {
        
      myPlayer.value = videojs(videoPlayer.value, {
        
        // poster: "//vjs.zencdn.net/v/oceans.png",//视频封面照片
        controls: true,//视频控件
        autoplay: true,//自动播放
        sources: [
          {
        
            src: `https://video.m3u8`,//播放视频地址
            type: 'application/x-mpegURL',//播放m3u8需要设置的格式
          }
        ],
        controlBar: {
        
          remainingTimeDisplay: {
        
            displayNegative: false
          }
        },
        playbackRates: [0.5, 1, 1.5, 2]//设置播放速度
      },)
    })
    //页面销毁时，销毁Video播放组件
    onUnmounted(() => {
        
      if (myPlayer.value) {
        
        myPlayer.value.dispose()
      }
    })

### 组件示例 ###

以下时项目使用中自己封装的组件，用起来也很简单，需要的可以对照自取  
UI框架为 ant-design-vue

<template>
      <div class="video_wrap">
        <div class="backIndex">
          <span @click="router.push({ path: '/videoList' })"><left-outlined /></span>
        </div>
        <video ref="videoPlayer" muted="muted" class="video-js video"></video>

    const videoPlayer = ref(null)
    const myPlayer = ref(null)
    const route = useRoute();
    const router = useRouter()
    let token = route.query.token;
    nextTick(() => {
        
      myPlayer.value = videojs(videoPlayer.value, {
        
        // poster: "//vjs.zencdn.net/v/oceans.png",//视频封面照片
