vue 中 使用 vedio.js 实现播放m3u8格式的视频

1安装

yarn add video.js

yarn add videojs-contrib-hls // 这是播放hls流需要的插件

yarn add mux.js // 在vue项目中，若不安装它可能报错

2 vue中 main.js中引入

//video js
import "video.js/dist/video-js.css"; // 引入video.js的css
import hls from "videojs-contrib-hls"; // 播放hls流需要的插件
Vue.use(hls);

3  实现播放m3u8格式的视频 

单个视频

<template>
  <div class="test-videojs">
    <video
      :id="postId"
      class="video-js"
      controls
      preload="none"
      poster="http://vjs.zencdn.net/v/oceans.png"
      :options="options"
    >
      <source :src="this.nowPlayVideoUrl" type="application/x-mpegURL" />
    </video>
  </div>
</template>
<script>
import Videojs from "video.js"; // 引入Videojs
export default {
  data() {
    return {
      postId: null,
      nowPlayVideoUrl:

      options: {
        autoplay: false, // 设置自动播放
        controls: true, // 显示播放的控件
      },
    };
  },
  mounted() {
    this.$nextTick(() => {
      this.initVideo(this.now);
    });
  },
  created() {
    this.postId = "video" + new Date().getTime().toString().substr(8);
  },
  methods: {
    initVideo() {
      let myPlyer = Videojs(
        this.postId,
        this.options,
        function onPlayerReady() {
          console.log("onPlayerReady 中的this指的是：", this); // 这里的this是指Player,是由Videojs创建出来的实例
          console.log(myPlyer === this); // 这里返回的是true
        }
      );
    },
  },
};
</script>
<style lang="scss">
.video-js {
   200px;
  height: 100px;
