vue播放倍速怎么实现

实现Vue播放倍速的方法

在Vue中实现播放倍速功能通常涉及HTML5的<video>元素或第三方播放器库。以下是几种常见实现方式：

使用原生HTML5 video元素

通过ref获取video实例，直接修改playbackRate属性：

<template>
  <div>
    <video ref="videoPlayer" controls>
      <source src="your-video.mp4" type="video/mp4">
    </video>
    <button @click="setPlaybackRate(1.5)">1.5x</button>
  </div>
</template>

<script>
export default {
  methods: {
    setPlaybackRate(rate) {
      this.$refs.videoPlayer.playbackRate = rate
    }
  }
}
</script>

使用video.js库

安装video.js后，通过player对象控制播放速度：

npm install video.js

组件实现：

<template>
  <div>
    <video ref="videoPlayer" class="video-js"></video>
    <button @click="changeSpeed(2)">2x</button>
  </div>
</template>

<script>
import videojs from 'video.js'
import 'video.js/dist/video-js.css'

export default {
  mounted() {
    this.player = videojs(this.$refs.videoPlayer, {
      sources: [{ src: 'your-video.mp4', type: 'video/mp4' }]
    })
  },
  methods: {
    changeSpeed(speed) {
      this.player.playbackRate(speed)
    }
  },
  beforeDestroy() {
    if (this.player) this.player.dispose()
  }
}
</script>

使用vue-video-player

基于video.js封装的Vue组件：

npm install vue-video-player

实现方式：

<template>
  <div>
    <video-player ref="player" :options="playerOptions"/>
    <button @click="setSpeed(0.5)">0.5x</button>
  </div>
</template>

<script>
import { videoPlayer } from 'vue-video-player'

export default {
  components: { videoPlayer },
  data() {
    return {
      playerOptions: {
        sources: [{ src: 'your-video.mp4', type: 'video/mp4' }]
      }
    }
  },
  methods: {
    setSpeed(rate) {
      this.$refs.player.player.playbackRate(rate)
    }
  }
}
</script>

动态速度选择

创建可交互的速度选择器：

<template>
  <div>
    <video ref="video" controls></video>
    <select v-model="playbackRate" @change="updateSpeed">
      <option value="0.5">0.5x</option>
      <option value="1" selected>1x</option>
      <option value="1.5">1.5x</option>
      <option value="2">2x</option>
    </select>
  </div>
</template>

<script>
export default {
  data() {
    return {
      playbackRate: 1
    }
  },
  methods: {
    updateSpeed() {
      this.$refs.video.playbackRate = parseFloat(this.playbackRate)
    }
  }
}
</script>
