## Example
Record camera & microphone, save data to MP4 file.
录制摄像头和麦克风，保存为 MP4 文件。

```ts
import { AVRecorder } from 'avrecorder-recorder'

// MediaStream from: getUserMedia, displayMedia, VideoHTMLElement.captureStream, VideoCanvasElement.captureStream, AVCanvas.captureStream etc...
const mediaStream = await navigator.mediaDevices.getUserMedia({
  video: true,
  audio: true
})

const recorder = new AVRecorder(mediaStream, {
  width: 1280,
  height: 720,
})
await recorder.start()

// pause recording
recorder.pause()

// resume recording
recorder.resume()

const fileHandle = await window.showSaveFilePicker({
  suggestedName: `av-recorder.mp4`
})

recorder.outputStream
  .pipeTo(await fileHandle.createWritable())


// await recorder.stop()
```
