cordova-plugin-iosrtc

Cordova iOS plugin exposing the full WebRTC W3C JavaScript APIs.

Yet another WebRTC SDK for iOS?

Absolutely not. This plugin exposes the WebRTC W3C API for Cordova iOS apps (you know there is no WebRTC in iOS, right?), which means no need to learn "yet another WebRTC API" and no need to use a specific service/product/provider.

Why?

Check the release announcement at the eFace2Face site.

Who?

This plugin was initially developed at eFace2Face, and later maintained by the community, specially by Saúl Ibarra Corretgé (The OpenSource Warrior Who Does Not Burn).

Requirements

In order to make this Cordova plugin run into a iOS application some requirements must be satisfied in both development computer and target devices:

  • Xcode >= 7.2.1
  • iOS >= 9 (run on lower versions at your own risk, but don't report issues)
  • cordova-ios 4.X

Installation

Within your Cordova project:

$ cordova plugin add cordova-plugin-iosrtc

(or add it into a <plugin> entry in the config.xml of your app).

Building

  • Building: Guidelines for building a Cordova iOS application including the cordova-plugin-iosrtc plugin.
  • Building libwebrtc: Guidelines for building Google's libwebrtc with modifications needed by the cordova-plugin-iosrtc plugin (just in case you want to use a different version of libwebrtc or apply your own changes to it).

Usage

The plugin exposes the cordova.plugins.iosrtc JavaScript namespace which contains all the WebRTC classes and functions.

var pc = new cordova.plugins.iosrtc.RTCPeerConnection({
  iceServers: []
});

cordova.plugins.iosrtc.getUserMedia(
  // constraints
  { audio: true, video: true },
  // success callback
  function (stream) {
    console.log('got local MediaStream: ', stream);

    pc.addStream(stream);
  },
  // failure callback
  function (error) {
    console.error('getUserMedia failed: ', error);
  }
);

In case you'd like to expose the API in the global namespace like regular browsers you can do the following:

// Just for Cordova apps.
document.addEventListener('deviceready', function () {
  // Just for iOS devices.
  if (window.device.platform === 'iOS') {
    cordova.plugins.iosrtc.registerGlobals();

    // load adapter.js
    var script = document.createElement("script");
    script.type = "text/javascript";
    script.src = "js/adapter-latest.js";
    script.async = false;
    document.getElementsByTagName("head")[0].appendChild(script);
  }
});

And that's all. Now you have window.RTCPeerConnection, navigator.getUserMedia, etc.

Who Uses It

People and companies using cordova-plugin-iosrtc.

If you are using the plugin we would love to hear back from you!

Known Issues

iOS Safari and crash on WebSocket events

Don't call plugin methods within WebSocket events (onopen, onmessage, etc). There is an issue in iOS Safari (see issue #12). Instead run a setTimeout() within the WebSocket event if you need to call plugin methods on it.

Or better yet, include the provided ios-websocket-hack.js in your app and load into your index.html as follows:

<script src="cordova.js"></script>
<script src="ios-websocket-hack.min.js"></script>

HTML5 video API

There is no real media source attached to the <video> element so some HTML5 video events and properties are artificially emitted/set by the plugin on behalf of the video element.

Methods such as play(), pause() are not implemented. In order to pause a video just set enabled = false on the associated MediaStreamTrack.
