vue实现监控视频直播的示范例子代码

要想使用videojs我们势必是需要安装videojs的, 而且在生产环境中我们也需要依赖它, 所以如下

npm: npm install video.js -S
npm install videojs-flash videojs-contrib-hls -S

我们打开Vue工程中的主入口main.js进行引入

// 引入videojs
import Video from 'video.js';
import 'video.js/dist/video-js.css';
Vue.prototype.$video = Video; 
import hls from 'videojs-contrib-hls';
Vue.use(hls); // 要播放hls流

创建监控视频九宫格

<template>
 <div class="cell">

  <div class="cell-player">
   <div :class="cellClass(i)" v-for="i in cellCount" :key="i">
    <playVideo :video="videoInfo[i]" v-if="cellCount != 6"></playVideo>
    <playVideo :video="videoInfo[i]" v-if="cellCount == 6 && i != 2 && i != 3"></playVideo>
    <template v-if="cellCount == 6 && i == 2">
     <div class="cell-player-6-2-cell">
      <playVideo :video="videoInfo[i]"></playVideo>
      <playVideo :video="videoInfo[++i]"></playVideo>
     </div>
    </template>
   </div>
  </div>
  <div class="cell-tool">
   <div class="bk-button-group">
<!--    <el-button @click="cellCount = 1" size="small">1</el-button>-->
    <el-button @click="cellCount = 4" size="small">4</el-button>
<!--    <el-button @click="cellCount = 6" size="small">6</el-button>-->
    <el-button @click="cellCount = 9" size="small">9</el-button>
<!--    <el-button @click="cellCount = 16" size="small">16</el-button>-->
   </div>
  </div>
 </div>
</template>

创建视频容器

虽然是遍历视频容器组件，但是监控视频只播放第一个，所以这里创建视频容器时，需要保证容器id不一致。

<template>
<div class="player">
 <div>{{video.name}}</div>
 <video :id='"A"+video.index'
    style="width: 100%;"
    class="video-js vjs-default-skin vjs-big-play-centered "> </video>
</div>
</template>

<script>
 export default {
  name: "playVideo",
  props: {
   video: {
    url: "",
    index:0,
   }
  },
  data() {return {}},
  mounted() {
   this.initVideoPlayer();
  },
  methods: {
   initVideoPlayer() {
    var that=this;
    var id="#A"+this.video.index;
     const currentInstance = that.$video(document.querySelector(id),{
      autoplay:true,
      controls:true
     }).src({
      src: that.video.url,
      type: 'application/x-mpegURL',
     })
   },
  }
 }
</script>
<style scoped>
 .player {
  background-color: black;
  width: 100%;
  height: 100%;
  border: 1px solid white;
  color: white;
  text-align: center;
 }
</style>
