Vue 实现录视频功能

使用浏览器 API 实现录屏

在 Vue 项目中可以通过浏览器提供的 MediaDevices API 和 MediaRecorder API 实现录屏功能。需要确保浏览器支持这些 API，通常在 Chrome、Firefox 等现代浏览器中可用。

<template>
  <div>
    <video ref="videoPreview" autoplay muted></video>
    <button @click="startRecording">开始录制</button>
    <button @click="stopRecording">停止录制</button>
    <a v-if="videoUrl" :href="videoUrl" download="recorded-video.webm">下载视频</a>
  </div>
</template>

<script>
export default {
  data() {
    return {
      mediaStream: null,
      mediaRecorder: null,
      recordedChunks: [],
      videoUrl: null
    };
  },
  methods: {
    async startRecording() {
      try {
        this.mediaStream = await navigator.mediaDevices.getDisplayMedia({
          video: true,
          audio: true
        });
        this.$refs.videoPreview.srcObject = this.mediaStream;

        this.mediaRecorder = new MediaRecorder(this.mediaStream);
        this.mediaRecorder.ondataavailable = (event) => {
          if (event.data.size > 0) {
            this.recordedChunks.push(event.data);
          }
        };
        this.mediaRecorder.onstop = () => {
          const blob = new Blob(this.recordedChunks, { type: 'video/webm' });
          this.videoUrl = URL.createObjectURL(blob);
          this.recordedChunks = [];
        };
        this.mediaRecorder.start();
      } catch (error) {
        console.error('Error accessing media devices:', error);
      }
    },
    stopRecording() {
      this.mediaRecorder.stop();
      this.mediaStream.getTracks().forEach(track => track.stop());
    }
  }
};
</script>

使用第三方库实现录屏

如果需要更复杂的录屏功能，可以考虑使用第三方库如 recordrtc。

安装依赖：

npm install recordrtc

示例代码：

<template>
  <div>
    <video ref="videoPreview" autoplay muted></video>
    <button @click="startRecording">开始录制</button>
    <button @click="stopRecording">停止录制</button>
  </div>
</template>

<script>
import RecordRTC from 'recordrtc';

export default {
  data() {
    return {
      recorder: null,
      stream: null
    };
  },
  methods: {
    async startRecording() {
      try {
        this.stream = await navigator.mediaDevices.getDisplayMedia({
          video: true,
          audio: true
        });
        this.$refs.videoPreview.srcObject = this.stream;

        this.recorder = new RecordRTC(this.stream, {
          type: 'video'
        });
        this.recorder.startRecording();
      } catch (error) {
        console.error('Error:', error);
      }
    },
    async stopRecording() {
      this.recorder.stopRecording(() => {
        const blob = this.recorder.getBlob();
        const url = URL.createObjectURL(blob);
        const a = document.createElement('a');
        a.href = url;
        a.download = 'recorded-video.webm';
        a.click();

        this.stream.getTracks().forEach(track => track.stop());
      });
    }
  }
};
</script>
