在Vue中实现视频功能

使用HTML5的<video>标签结合Vue的数据绑定和事件处理能力可以轻松实现视频播放功能。以下是一个基础实现示例：

<template>
  <div>
    <video 
      ref="videoPlayer"
      :src="videoSrc"
      controls
      @play="onPlay"
      @pause="onPause"
      @ended="onEnded"
    ></video>
    <button @click="togglePlay">{{ isPlaying ? '暂停' : '播放' }}</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      videoSrc: 'path/to/your/video.mp4',
      isPlaying: false
    }
  },
  methods: {
    togglePlay() {
      const video = this.$refs.videoPlayer
      this.isPlaying ? video.pause() : video.play()
    },
    onPlay() {
      this.isPlaying = true
    },
    onPause() {
      this.isPlaying = false
    },
    onEnded() {
      this.isPlaying = false
    }
  }
}
</script>

使用第三方视频播放器库

对于更复杂的视频需求，可以考虑使用专门的Vue视频播放器组件：

vue如何实现视频

vue-video-player：基于Video.js的Vue组件
```
npm install vue-video-player video.js
```

<template>
  <video-player 
    :options="playerOptions" 
    @ready="onPlayerReady"
  />
</template>

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

export default {
  components: {
    videoPlayer
  },
  data() {
    return {
      playerOptions: {
        autoplay: false,
        controls: true,
        sources: [{
          src: 'path/to/video.mp4',
          type: 'video/mp4'
        }]
      }
    }
  },
  methods: {
    onPlayerReady(player) {
      console.log('播放器已就绪', player)
    }
  }
}
</script>

vue-plyr：轻量级的HTML5播放器
```
npm install vue-plyr
```

<template>
  <plyr>
    <video controls crossorigin>
      <source :src="videoSrc" type="video/mp4">
    </video>
  </plyr>
</template>

<script>
import VuePlyr from 'vue-plyr'

export default {
  directives: {
    plyr: VuePlyr
  },
  data() {
    return {
      videoSrc: 'path/to/video.mp4'
    }
  }
}
</script>

实现视频流功能

对于直播或实时视频流，可以使用以下技术方案：

vue如何实现视频

<template>
  <video ref="streamPlayer" autoplay muted></video>
</template>

<script>
export default {
  mounted() {
    this.setupStream()
  },
  methods: {
    async setupStream() {
      try {
        const stream = await navigator.mediaDevices.getUserMedia({
          video: true,
          audio: true
        })
        this.$refs.streamPlayer.srcObject = stream
      } catch (error) {
        console.error('获取媒体设备失败:', error)
      }
    }
  }
}
</script>

视频自定义控件开发

通过Vue可以完全自定义视频控制界面：

<template>
  <div class="video-container">
    <video ref="video" :src="videoSrc" @timeupdate="updateTime"></video>
    <div class="controls">
      <button @click="togglePlay">{{ isPlaying ? '❚❚' : '▶' }}</button>
      <input 
        type="range" 
        v-model="currentTime" 
        min="0" 
        :max="duration"
        @input="seek"
      >
      <span>{{ formattedTime }}</span>
      <button @click="toggleMute">{{ isMuted ? '🔊' : '🔇' }}</button>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      videoSrc: 'path/to/video.mp4',
      isPlaying: false,
      currentTime: 0,
      duration: 0,
      isMuted: false
    }
  },
  computed: {
    formattedTime() {
      const minutes = Math.floor(this.currentTime / 60)
      const seconds = Math.floor(this.currentTime % 60)
      return `${minutes}:${seconds < 10 ? '0' : ''}${seconds}`
    }
  },
  methods: {
    togglePlay() {
      const video = this.$refs.video
      this.isPlaying ? video.pause() : video.play()
    },
    updateTime() {
      const video = this.$refs.video
      this.currentTime = video.currentTime
      this.duration = video.duration
    },
    seek(e) {
      this.$refs.video.currentTime = e.target.value
    },
    toggleMute() {
      this.$refs.video.muted = !this.isMuted
      this.isMuted = !this.isMuted
    }
  }
}
</script>

视频上传与预览

实现视频上传和预览功能：

<template>
  <div>
    <input type="file" accept="video/*" @change="handleFileChange">
    <video v-if="videoUrl" :src="videoUrl" controls></video>
    <button v-if="videoFile" @click="uploadVideo">上传视频</button>
  </div>
</template>

<script>
export default {
  data() {
    return {
      videoFile: null,
      videoUrl: ''
    }
  },
  methods: {
    handleFileChange(e) {
      const file = e.target.files[0]
      if (file) {
        this.videoFile = file
        this.videoUrl = URL.createObjectURL(file)
      }
    },
    async uploadVideo() {
      const formData = new FormData()
      formData.append('video', this.videoFile)

      try {
        const response = await fetch('/api/upload', {
          method: 'POST',
          body: formData
        })
        const data = await response.json()
        console.log('上传成功:', data)
      } catch (error) {
        console.error('上传失败:', error)
      }
    }
  }
}
</script>
