npm install rtc-everywhere --save

1var rtc = require('rtc-everywhere')();

3// Available:
4// rtc.RTCPeerConnection
5// rtc.RTCIceCandidate
6// rtc.RTCSessionDescription
7// rtc.getUserMedia
8// rtc.attachStream(stream, videoElement)

API

RTCPeerConnection

Exactly the same as the specification. See the Specification Documentation!

RTCIceCandidate

Exactly the same as the specification. See the Specification Documentation!

RTCSessionDescription

Exactly the same as the specification. See the Specification Documentation!

getUserMedia(constraints, cb)

Similar to the specification, but slightly adjusted to have an easier API.

Modifications

• constraints is optional (makes things easier)

  • Defaults to {video: true, audio: true}

• cb is a node-style error first callback

1// these are the same thing
2rtc.getUserMedia(function(err, stream){});
3rtc.getUserMedia({video: true, audio: true}, function(err, stream){});

attachStream(stream, element)

• Attaches a stream to a given video element
• Returns the element the video was attached to
• In IE and Safari, the video element will be replaced by an object element
  • Elements will not be replaced or modified unless they exist on the DOM
  • Regardless of replacement, the new object element will be returned
