節點 puppeteer stream 不錄制音頻

Question

我正在嘗試使用 puppeteer stream 錄制視頻和音頻，但它只將視頻寫入 output 文件：

async function videoRecorder() {
  require("puppeteer-stream");
  const puppeteer = require("puppeteer");
  const fs = require("fs");

  const filename = `./recordings/test.mp4`;

  const file = fs.createWriteStream(filename);

  const browser = await puppeteer.launch({
    executablePath:
      "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome",
    headless: true,
    defaultViewport: null,
    devtools: false,
    args: [
      "--window-size=1920,1080",
      "--window-position=1921,0",
      "--autoplay-policy=no-user-gesture-required",
    ],
    ignoreDefaultArgs: ["--mute-audio"],
  });

  const page = await browser.newPage();

  await page.goto(pathToPageWithVideo, {
    waitUntil: "load",
  });

  const stream = await page.getStream({
    audio: true,
    video: true,
  });

  stream.pipe(file);

  setTimeout(async () => {
    await stream.destroy();
    file.close();
    console.log("finished");
  }, 10000);
}

我嘗試了許多其他錄制視頻和音頻的方法，但這是我更接近的一種，因為我的主要目的是只獲取音頻，我願意接受更多建議。

謝謝

通過另存為.webm 而不是.mp4 解決。
