实现无缝播放视频的方法

在Vue中实现无缝播放视频，可以通过监听视频结束事件并动态切换视频源来实现。以下是一个完整的实现方案：

创建视频组件

<template>
  <div>
    <video 
      ref="videoPlayer" 
      autoplay 
      playsinline 
      @ended="handleVideoEnd"
    ></video>
  </div>
</template>

设置视频源列表

data() {
  return {
    videoSources: [
      'video1.mp4',
      'video2.mp4',
      'video3.mp4'
    ],
    currentVideoIndex: 0
  }
}

处理视频结束事件

methods: {
  handleVideoEnd() {
    this.currentVideoIndex = (this.currentVideoIndex + 1) % this.videoSources.length
    this.$refs.videoPlayer.src = this.videoSources[this.currentVideoIndex]
    this.$refs.videoPlayer.play()
  }
}

初始化视频播放

mounted() {
  this.$refs.videoPlayer.src = this.videoSources[0]
  this.$refs.videoPlayer.play()
}

优化播放体验的技巧

添加预加载功能可以进一步提升无缝播放体验。在视频播放时预加载下一个视频：

methods: {
  preloadNextVideo() {
    const nextIndex = (this.currentVideoIndex + 1) % this.videoSources.length
    const preloadVideo = document.createElement('video')
    preloadVideo.src = this.videoSources[nextIndex]
  }
}

在mounted和handleVideoEnd方法中调用preloadNextVideo：

mounted() {
  this.$refs.videoPlayer.src = this.videoSources[0]
  this.$refs.videoPlayer.play()
  this.preloadNextVideo()
}

handleVideoEnd() {
  this.currentVideoIndex = (this.currentVideoIndex + 1) % this.videoSources.length
  this.$refs.videoPlayer.src = this.videoSources[this.currentVideoIndex]
  this.$refs.videoPlayer.play()
  this.preloadNextVideo()
}

添加过渡效果

为视频切换添加淡入淡出效果，提升用户体验：

video {
  transition: opacity 0.5s ease-in-out;
}

.fade-out {
  opacity: 0;
}

修改handleVideoEnd方法：

handleVideoEnd() {
  this.$refs.videoPlayer.classList.add('fade-out')

  setTimeout(() => {
    this.currentVideoIndex = (this.currentVideoIndex + 1) % this.videoSources.length
    this.$refs.videoPlayer.src = this.videoSources[this.currentVideoIndex]
    this.$refs.videoPlayer.classList.remove('fade-out')
    this.$refs.videoPlayer.play()
    this.preloadNextVideo()
  }, 500)
}

处理移动端自动播放限制

移动端浏览器通常限制自动播放，需要添加用户交互处理：

mounted() {
  if ('autoplay' in this.$refs.videoPlayer) {
    this.$refs.videoPlayer.autoplay = true
    this.$refs.videoPlayer.src = this.videoSources[0]
    this.preloadNextVideo()
  } else {
    document.addEventListener('click', this.initVideoPlayer, { once: true })
  }
}

methods: {
  initVideoPlayer() {
    this.$refs.videoPlayer.src = this.videoSources[0]
    this.$refs.videoPlayer.play()
    this.preloadNextVideo()
  }
}
