有没有一种方法可以从用户上传的mp4中拉出音频并点击按钮播放？

<input type="file" id="fileInput">
<button id="playButton">播放音频</button>
<video id="videoPlayer" controls></video>
<audio id="audioPlayer" controls></audio>

const fileInput = document.getElementById('fileInput');
const playButton = document.getElementById('playButton');
const videoPlayer = document.getElementById('videoPlayer');
const audioPlayer = document.getElementById('audioPlayer');

fileInput.addEventListener('change', function() {
  const file = fileInput.files[0];
  const videoURL = URL.createObjectURL(file);
  videoPlayer.src = videoURL;
});

playButton.addEventListener('click', function() {
  const videoStream = videoPlayer.captureStream();
  const audioStream = new MediaStream();
  
  videoStream.getAudioTracks().forEach(function(track) {
    audioStream.addTrack(track);
  });
  
  audioPlayer.srcObject = audioStream;
  audioPlayer.play();
});
