An Extension for Puppeteer to retrieve audio and/or video streams of a page
npm i puppeteer-stream
# or "yarn add puppeteer"
ES5 import
require("puppeteer-stream");
const puppeteer = require("puppeteer");
or ES6 import
import "puppeteer-stream";
import puppeteer from "puppeteer";
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.
The method page.getStream(options)
takes the following options:
{
audio: boolean; // wheter or not to enable audio
video: boolean; // wheter 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<
