Not recording audio

[dazzzed]

I'm trying to record video and audio using puppeteer stream, but it's getting written only the video to the output file:

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);
}

i'll have a look tomorrow

You are writing to a .mp4file however the default format is webm.
Also can you send the pathToPageWithVideo value

@Flam3rboy I've tried with webm and din't work either.
The pathToPageWithVideo I was testing with was https://www.rtp.pt/play/p8157/e518677/telejornal

[SamuelScheit]

also note that chrome doesn't support mimeType video/mp4.
Have a look at the HTML5 MediaRecorder Options

[SamuelScheit]

weirdly enough everything works with video/webm as mimeType and saving it as an .webm file

[tiagocostafdm]

so you got it to save a file with audio and video by setting the mimeType to video/webm and saving as webm?

[SamuelScheit]

yes everything the same

[dazzzed]

@Flam3rboy yes I got it just opened it with another player, thanks.
One more thing, how can I save it as mp3 audio only?

[SamuelScheit]

only if the browser supports mp3 just specify the mimeType
