Mute the browser audio

[SaadAI2]

async function videoRecorder() { const {getStream,launch}=require("puppeteer-stream"); const puppeteer = require("puppeteer-extra"); const fs = require("fs"); const StealthPlugin = require("puppeteer-extra-plugin-stealth"); puppeteer.use(StealthPlugin()); const filename = ./test.webm;

const file = fs.createWriteStream(filename);
let url= "https://www.youtube.com/watch?v=dQw4w9WgXcQ"

const browser = await launch({
//  executablePath:'/usr/bin/google-chrome',
//  "/Applications/Google Chrome.app/Contents/MacOS/Google Chrome",
  headless: false,
  args: [
    // "--headless=new",
    // "--use-fake-ui-for-media-stream",
    "--use-fake-device-for-media-stream",
],
executablePath: puppeteer.executablePath(),

});

const page = await browser.newPage();
await page.goto(url);

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

}

videoRecorder() I am attempting to capture an audio stream for a YouTube video. However, when the browser initiates the stream capture, it mutes the video sound and returns a null stream.

},

} This is output i am getting from above code.

The chrome tab capturer mutes the tab, if it is being recorded. (that is normal behavior) The stream is not null, the log you've sent is the PuppeteerReadableStream, which is the expected return type. Have a look at the example to see how you can use the stream.
