实现倍速播放功能

在Vue中实现倍速播放功能通常涉及HTML5的<video>元素或第三方播放器库（如video.js）。以下是两种常见的实现方式：

使用原生HTML5 video元素

通过直接操作<video>元素的playbackRate属性实现倍速控制：

<template>
  <div>
    <video ref="videoPlayer" controls>
      <source src="your-video.mp4" type="video/mp4">
    </video>
    <button @click="setPlaybackRate(1)">1x</button>
    <button @click="setPlaybackRate(1.5)">1.5x</button>
    <button @click="setPlaybackRate(2)">2x</button>
  </div>
</template>

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

使用video.js库

对于更复杂的播放器需求，可集成video.js：

<template>
  <div>
    <video ref="videoPlayer" class="video-js"></video>
    <button @click="changeSpeed(0.5)">0.5x</button>
    <button @click="changeSpeed(1)">1x</button>
  </div>
</template>

<script>
import videojs from 'video.js';

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>

动态倍速选择器

添加下拉菜单实现动态速率调整：

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

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