vue的nuxt框架中使用vue-video-player

  一、基本需求:使用nuxt框架,需要在移动端网页中播放视频。
  二、文中解决的基本问题:
      1、vue-video-player在nuxt中怎么使用。
      2、由于为了适配移动端,使用了postcss-px2rem插件,如何解决vue-video-player的样式与postcss-px2rem插件的冲突。
      3、如何播放m3u8的视频。
  三、解决方案:
      1、vue-video-player在nuxt中的使用:
        1) npm i vue-video-player --save
        2) 编写插件: 在plugins目录下新建 videoPlayer.js文件

 import Vue from 'vue'
 const VueVideoPlayer = require('vue-video-player/dist/ssr')
 Vue.use(VueVideoPlayer)

  3)创建组件: 在components文件下新建VueVideo.vue文件,注意class="video-player-box" 这个是约定的。

<template>
  <section class="vueVideo">
    <div
      v-video-player:myVideoPlayer="playerOptions"
      class="video-player-box"
      :playsinline="playsinline"
      @play="onPlayerPlay($event)"
      @pause="onPlayerPause($event)"
      @ended="onPlayerEnded($event)"
      @loadeddata="onPlayerLoadeddata($event)"
      @waiting="onPlayerWaiting($event)"
      @playing="onPlayerPlaying($event)"
      @timeupdate="onPlayerTimeupdate($event)"
      @canplay="onPlayerCanplay($event)"
      @canplaythrough="onPlayerCanplaythrough($event)"
      @ready="playerReadied"
      @statechanged="playerStateChanged($event)"
    ></div>
  </section>
</template>

<script>
import 'video.js/dist/video-js.css'
import 'vue-video-player/src/custom-theme.css'
export default {
  data() {
    return {
      playsinline: true,
      playerOptions: {
        // 播放器配置
        muted: false, // 是否静音
        language: 'zh-CN',
        // aspectRatio: '16:9',
        playbackRates: [0.7, 1.0, 1.5, 2.0], // 播放速度
        controls: true,
        preload: 'auto', // 视频预加载
        fluid: true,
        sources: [
          {
             type: 'video/mp4',
             src:
               'https://cdn.theguardian.tv/webM/2015/07/20/150716YesMen_synd_768k_vp8.webm'
           }
        ],
        poster: '/imgs/choice/avator.png', // 封面图
        notSupportedMessage: '此视频暂无法播放,请稍后再试'
      }
    }
  },
  mounted() {
    console.log('this is current player instance object', this.myVideoPlayer)
  },
  methods: {
    // 监听播放
    onPlayerPlay(player) {
      // console.log('player play!', player)
    },
    // 监听暂停
    onPlayerPause(player) {
      // console.log('player pause!', player)
    },
    // 监听停止
    onPlayerEnded(player) {
      // console.log('player ended!', player)
    },
    // 监听加载完成
    onPlayerLoadeddata(player) {
      // console.log('player Loadeddata!', player)
    },
    // 监听视频缓存等待
    onPlayerWaiting(player) {
      // console.log('player Waiting!', player)
    },
    // 监听视频暂停后播放
    onPlayerPlaying(player) {
      // console.log('player Playing!', player)
    },
    // 监听视频播放时长更新
    onPlayerTimeupdate(player) {
      // console.log('player Timeupdate!', player.currentTime())
    },
    onPlayerCanplay(player) {
      console.log('player Canplay!', player)
    },
    onPlayerCanplaythrough(player) {
      // console.log('player Canplaythrough!', player)
    },
    // 监听状态改变
    playerStateChanged(playerCurrentState) {
      // console.log('player current update state', playerCurrentState)
    },
    // 监听播放器准备就绪
    playerReadied(player) {
      // console.log('example 01: the player is readied', player)
    }
  }
}
</script>

<style lang="scss" scoped></style>

  4)配置nuxt.config.js文件

css: [
    'video.js/dist/video-js.css',
  ],
plugins: [{ src: '~plugins/videoPlayer.js', ssr: false }],

  5)调用组件(只写了关键代码)

<template>
  <div>
    <VueVideo></VueVideo>
  </div>
</template>

import VueVideo from '~/components/VueVideo'

components: {
    VueVideo
  },

  2、解决适配问题:

    postcss-px2rem插件主要是用来适配各种大小的移动端设备,将px转换成rem。但是他会影响到node_modules中的插件的样式。所以,将postcss-px2rem插件换成postcss-px2rem-exclude插件,postcss-px2rem-exclude的好处是可以排除那些不需要要进行单位转化的文件。

1)安装

  npm uninstall postcss-px2rem

  npm i postcss-px2rem-exclude -D

2)配置

npm i postcss-px2rem-exclude的官方文档

module.exports = {
  'plugins': {
    'postcss-px2rem-exclude': {
      remUnit: 75,
      exclude: /node_modules|folder_name/i
    }
  }
}

在我的nuxt中的配置是:在nuxt.config.js文件中

  build: {
    /*
     ** You can extend webpack config here
     */
    postcss: [
      require('postcss-px2rem-exclude')({
        remUnit: 75,
        exclude: /video.js/i
      })
    ]
  }

这样postcss-px2rem-exclude就会吧node_modules/video.js文件夹下面的样式排除掉。从而video的样式不会受到postcss-px2rem-exclude的影响。

3、播放m3u8视频

1)先安装videojs-contrib-hls插件

npm i videojs-contrib-hls  --save

2)修改之前的videoPlayer.js文件

import Vue from 'vue'
const VueVideoPlayer = require('vue-video-player/dist/ssr')
// 若是只是想播放普通视频,则不需要videojs-contrib-hls
const hls = require('videojs-contrib-hls')
Vue.use(hls)
Vue.use(VueVideoPlayer)

3)修改VueVideo.vue文件,可换成直播流,这是CCTV1的直播流。

sources: [
          // {
          //   type: 'video/mp4',
          //   src:
          //     'https://cdn.theguardian.tv/webM/2015/07/20/150716YesMen_synd_768k_vp8.webm'
          // }
          // 直播流
          {
            type: 'application/x-mpegURL/video/mp4',
            src: 'http://ivi.bupt.edu.cn/hls/cctv1hd.m3u8'
          }
        ]
