videojs 在vue中使用，解决手机端全屏问题

1. 封装 VideoPlayer.vue 组件

<template>
  <div>
    <video class="video-js vjs-big-play-centered" ref="videoPlayer"></video>
  </div>
</template>

<script>
  import videojs from 'video.js'

  export default {
    name: 'VideoPlayer',
    props: {
      options: {
        type: Object,
        default() {
          return {}
        }
      }
    },
    data() {
      return {
        player: null
      }
    },
    mounted() {
      this.player = videojs(this.$refs.videoPlayer, this.options, function onPlayerReady() {
        console.log('onPlayerReady', this)
        this.on('fullscreenchange', function() {
          if (this.isFullscreen()) {
            this.enterFullWindow()
          } else {
            this.exitFullWindow()
          }
        })
      })
    },
    beforeDestroy() {
      if (this.player) {
        this.player.dispose()
      }
    }
  }
</script>
<style lang="less" scoped>
  .video-js {
    margin: 0px auto;
  }
</style>

2. 使用组件

<template>
  <div>
    <video-player :options="videoOptions" />
  </div>
</template>

<script>
  import VideoPlayer from '@/components/VideoPlayer.vue'
  let clientWidth = document.documentElement.clientWidth

  export default {
    name: 'VideoExample',
    components: {
      VideoPlayer
    },
    data() {
      return {
        videoOptions: {
          width: clientWidth > 1000 ? 1000 : clientWidth,
          autoplay: true,
          controls: true,
          fluid: true,
          sources: [
            {
              src: 'http://localhost/live/penrosestream.m3u8',
              type: 'application/x-mpegURL'
            }
          ]
        }
      }
    },
    mounted() {
      console.log(document.body.clientWidth, document.documentElement.clientWidth)
    }
  }
</script>
