screen-record

Capture desktop video using webrtc

Installation

This client-side module is installed via npm:

$ npm install screen-record

It is a client-side browser that gives desktop recording capabilities to Chrome when this Chrome Extension is installed.

Example Usage

var screenRecord = require('screen-record'),
    getUserMedia = require('getusermedia');
screenRecord(window, (err, sourceId, constraints) => {
  if (err) throw err;

  getUserMedia(constraints, function (err, stream) {
    if (err) throw err;

    // now have a webRTC stream of the desktop
  })
});

API

screenRecord([window], cb(err, sourceId, contraints))

Asks the Chome Extension to ask the user to authorize and pick a window or the whole desktop to record.

• window - Optional DOM window object to use to do screen recording magic (IFRAME insertion, postMessage etc).
• cb(err, sourceId, constraints) - Callback:
  • err - Error
  • sourceId - The unique webrtc source ID string, that can be passed through a constraints object in getUserMedia to then create a webrtc stream.
  • constraints - Prefilled and ready-to-use getUserMedia constraints object that can be directly used. The sourceId is already correctly populated.
