puppeteer-stream

An Extension for Puppeteer to retrieve audio and/or video streams of a page

Installation

npm i puppeteer-stream
# or "yarn add puppeteer"

Usage

ES5 import

require("puppeteer-stream");
const puppeteer = require("puppeteer");

or ES6 import

import "puppeteer-stream";
import puppeteer from "puppeteer";

Notice

This will patch the launch method of puppeteer to start with this record extension and will add a page.getStream(options) method to all pages.

This will only work in headful mode

The method page.getStream(options) takes the following options

{
	audio: boolean; // whether or not to enable audio
	video: boolean; // whether or not to enable video
	mimeType?: string; // optional mime type of the stream, e.g. "audio/webm" or "video/webm"
	audioBitsPerSecond?: number; // The chosen bitrate for the audio component of the media.
	videoBitsPerSecond?: number; // The chosen bitrate for the video component of the media.
	bitsPerSecond?: number; // The chosen bitrate for the audio and video components of the media. This can be specified instead of the above two properties. If this is specified along with one or the other of the above properties, this will be used for the one that isn't specified.
	frameSize?: number = 20; // The number of milliseconds to record into each packet.
}

and returns a Promise<Readable>

For a detailed documentation of the options have a look at the HTML5 MediaRecorder Options

Example

Save Stream to File:

require("puppeteer-stream");
const puppeteer = require("puppeteer");
const fs = require("fs");

const file = fs.createWriteStream(__dirname + "/test.webm");

async function test() {
	const browser = await puppeteer.launch({
		defaultViewport: {
			width: 1920,
			height: 1080,
		},
	});

	const page = await browser.newPage();
	await page.goto("https://dl5.webmfiles.org/big-buck-bunny_trailer.webm");
	const stream = await page.getStream({ audio: true, video: true });
	console.log("recording");

	stream.pipe(file);
	setTimeout(async () => {
		await stream.destroy();
		file.close();
		console.log("finished");
	}, 1000 * 10);
}

test();
