WebRTC allows for real-time communications capabilities directly in the browser. Mozilla is working to integrate WebRTC into Firefox and Firefox OS to enable features like video chat. Some current focuses include fixing bugs, improving audio recording support, and bringing WebRTC to the initial release of Firefox OS later this year after the v1.1 version. Firefox OS uses open web technologies and various device APIs to build customizable apps and interfaces for the mobile operating system.

WebRTC & Firefox OS - presentation at Google
- 1. WebRTC & Firefox OS
- 4. @robertnyman
- 5. Mozilla is a global non- profit dedicated to putting you in control of your online experience and shaping the future of the Web for the public good
- 8. WebRTC
- 12. var video = document.querySelector('video'); navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia || navigator.msGetUserMedia; window.URL = window.URL || window.webkitURL || window.mozURL || window.msURL; // Call the getUserMedia method with our callback functions if (navigator.getUserMedia) { navigator.getUserMedia({video: true}, successCallback, errorCallback); } else { console.log('Native web camera streaming (getUserMedia) not supported in this browser.'); // Display a friendly "sorry" message to the user }
- 13. function successCallback(stream) { // Set the source of the video element with the stream from the camera if (video.mozSrcObject !== undefined) { video.mozSrcObject = stream; } else { video.src = (window.URL && window.URL.createObjectURL(stream)) || stream; } video.play(); }
- 20. Firefox & WebRTC status
- 21. "Fix a lot of bugs and improve quality"
- 22. First implementation in Firefox 22, including DataChannels TURN support for Desktop in Firefox 23 Audio recording support. We hope to get it landed in Firefox 24 We haven't started working on video recording Desktop
- 23. Stretch goal of shipping WebRTC (pref'd on) in Firefox 24 -- though Firefox 25 is more likely. It is already in Firefox 23 for Android, but behind a pref (the same pref that desktop was behind) Android
- 24. We're starting to get WebRTC functioning on Firefox OS. gUM will come first. Since Firefox OS doesn't ship on the train system, the initial code for this will likely ship later in the year (sometime after Firefox OS v1.1) Firefox OS
- 25. Persona/Identity integration BUNDLE SDP renegotiation via new offer/answer pair Statistics API (at least the framework for it) persistent permissions support more than 1 audio flow and 1 video flow Roadmap
- 26. Using HTML5, CSS and JavaScript together with a number of APIs to build apps and customize the UI. Firefox OS
- 27. A walk in the park
- 28. Open Web Apps
- 30. Packaged vs. Hosted Apps
- 31. WebAPIs
- 33. Security Levels
- 34. Web Content Regular web content Installed Web App A regular web app Privileged Web App More access, more responsibility Certified Web App Device-critical applications

- 45. DEVICEPROXIMITY

- 48. window.addEventListener("devicelight", function (event) { // The lux values for "dim" typically begin below 50, // and the values for "bright" begin above 10000 console.log(event.value); });
- 49. Device Storage API Browser API TCP Socket API Contacts API systemXHR PRIVILEGED APIS
- 51. var deviceStorage = navigator.getDeviceStorage("videos");

- 53. var storage = navigator.getDeviceStorage("videos"), cursor = storage.enumerate(); cursor.onerror = function() { console.error("Error in DeviceStorage.enumerate()", cursor.error.name); }; cursor.onsuccess = function() { if (!cursor.result) return; var file = cursor.result; // If this isn't a video, skip it if (file.type.substring(0, 6) !== "video/") { cursor.continue(); return; } // If it isn't playable, skip it var testplayer = document.createElement("video"); if (!testplayer.canPlayType(file.type)) { cursor.continue(); return; } };
- 54. WEB ACTIVITIES
- 55. Interacting with the camera
- 57. var activity = new MozActivity({ name: "view", data: { type: "image/png", url: ... } }); activity.onsuccess = function () { console.log("Showing the image!"); }; activity.onerror = function () { console.log("Can't view the image!"); };
- 58. { "activities": { "share": { "filters": { "type": ["image/png", "image/gif"] } "href": "sharing.html", "disposition": "window" } } }
