Getting Started with WebRTC

Getting Started with WebRTC
WebRTC is a new front in the long war for an open and unencumbered web. Brendan Eich, inventor of JavaScript Real-time communication without plugins Imagine a world where your phone, TV and computer could all communicate on a common platform. Want to try it out? Open apprtc.appspot.com in Chrome, Opera or Firefox. There is a walkthrough of this application later in this article. Quick start Haven't got time to read this article, or just want code? Get an overview of WebRTC from the Google I/O presentation (the slides are here): If you haven't used getUserMedia, take a look at the HTML5 Rocks article on the subject, and view the source for the simple example at simpl.info/gum. Alternatively, jump straight into our WebRTC codelab: a step-by-step guide that explains how to build a complete video chat app, including a simple signaling server. A very short history of WebRTC WebRTC has now implemented open standards for real-time, plugin-free video, audio and data communication. Where are we now? Related:  javascript

Infographic: The Entire JavaScript Language in One Single Image Chinese-based developer Yusheng, has created a nice graphic that assembles the entire JavaScript programming syntax into one single all-encompassing image. Regardless of what the TIOBE Index says, JavaScript, and not Java, is the hottest programming language right now. This popularity was won very hard, having to fight through a period where the language seemed to have stood still with no new features being released for a period of four years. Despite this, developers rushed to the language, mainly due to the technologies being developed on top of it, and more specifically Node.js. If today some of you want to delve into JavaScript in the upcoming future, there are many tutorials you can find online, all great resources for learning the language's fundamentals from the ground up in a matter of days. But if things are constantly escaping your memory, Chinese-based developer Yusheng has assembled a nice mind map of the entire JavaScript language syntax, complete with code examples.

WebRTC WebRTC Un article de Wikipédia, l'encyclopédie libre. WebRTC (Web Real-Time Communication, littéralement communication web en temps réel) est une interface de programmation (API) JavaScript actuellement au stade de brouillon (Draft) développée au sein du W3C et de l'IETF. C'est aussi un canevas logiciel avec des implémentations précoces dans différents navigateurs web pour permettre une communication en temps réel. Le but du WebRTC est de lier des applications comme la voix sur IP, le partage de fichiers en pair à pair en s'affranchissant des plugins propriétaires jusqu'alors nécessaires. La technologie WebRTC étant récente, son intégration au sein des différents navigateurs internet est encore inégale. Historique[modifier | modifier le code] Cependant, ces initiatives s'opposent à Microsoft qui a soumis une proposition concurrente CU-RTC-WEB (en) le 8 août 2012[11]. Le standard qui établira le WebRTC n'étant pas encore complet, il peut encore subir de fortes modifications.

webRTC-io/webRTC.io · GitHub WebRTC in the real world: STUN, TURN and signaling What is signaling? Signaling is the process of coordinating communication. In order for a WebRTC application to set up a 'call', its clients need to exchange information: Session control messages used to open or close communication.Error messages.Media metadata such as codecs and codec settings, bandwidth and media types.Key data, used to establish secure connections.Network data, such as a host's IP address and port as seen by the outside world. This signaling process needs a way for clients to pass messages back and forth. Why is signaling not defined by WebRTC? To avoid redundancy and to maximize compatibility with established technologies, signaling methods and protocols are not specified by WebRTC standards. JSEP's architecture also avoids a browser having to save state: that is, to function as a signaling state machine. JSEP requires the exchange between peers of offer and answer: the media metadata mentioned above. Want to know what all this SDP gobbledygook actually means? <!

javascript-society/javascript-path WebRTC Book Multiplayer is coming One of the most highly demanded features for Construct 2 has been support for making real-time multiplayer online games. While we have supported WebSockets for some time, it has two key barriers to real-time multiplayer: the need to write a separate server, and the guaranteed in-order transmission using TCP. This can create head-of-line blocking and ruin the performance of latency-sensitive games, compared to UDP which can ignore dropped packets and reduce latency. With the arrival of Chrome 32 and Firefox 27, we now have a solution: WebRTC DataChannels! What is WebRTC? WebRTC is a new browser feature allowing peer-to-peer connections. Peer-to-peer connections have the advantage that you don't need to write or even host a separate server! Which platforms are supported? Currently only Chrome 32+ and Firefox 27+ support interoperable WebRTC DataChannels. Features of the multiplayer engine We are writing our own custom multiplayer engine to best suit the needs of Construct 2 developers. Demos

priologic/easyrtc A Web RTC Tutorial With WebRTC, adding a peer-to-peer video chat to a site is as easy as child's play and the best part of it is that there is no need for your users to download plugins to use the service. There are two pieces needed to set up peer-to-peer video chat using WebRTC: an HTML5 compliant browser, and the proper code on your server. This blog will walk you through the steps to get a simple service up and running. WebRTC is part of the HTML5 standard and is still under development. Installing the Browser To install the browser, follow the steps here. /usr/lib/webkitgtk-1.0-0/libexec/GtkLauncher If you see a page with a Captcha, you're all set to go, but if you see a warning that your browser lacks support for PeerConnection video conferencing you need to track down the problem. Note that the following steps are only required if you want to host the signaling server yourself. Setting up the Server With the browser part cleared, we'll now turn to the server setup. <!

11 Free jQuery CSS3 Navigation Menu Plugins These days, jQuery Navigation menus are more than plain texts with links on it. With the command of jQuery, it can transform the menu of a web site into a dynamic menu. Despite the fact that CSS3 can now be utilized to make dynamic menu, still, the query includes more functionality to the menus. Aside from the element functionalities, the design should likewise be considered. Because of audience your site would perhaps see it for the first time they visit your website. If it is not well designed any having worst UI experience so it will not give you value add to your site. You Might be interested on : Free jQuery Sliders and jQuery autocomplete Tutorials.

webrtc · WebPlatform.org This page has been flagged with the following issues: W3C Working Draft Summary Enables real-time communication across the web. Usage The RTC in WebRTC stands for Real-Time Communications, technology that enables audio/video streaming and data sharing between browser clients (peers). WebRTC components are accessed with JavaScript APIs. MediaStream API A MediaStream object is typically set as a simple URL string which can be used to reference data stored in a DOM File or Blob object with window.URL.createObjectURL(). A MediaStream consists of zero or more MediaStreamTrack objects, which comprise one or more channels, and which are contained in a MediaStreamTrackList. MediaStream objects have an input and an output. PeerConnection API The PeerConnection API, represented chiefly by the RTCPeerConnection object, provides for the exchange of MediaStream object data between browser instances (peers) across a secure channel.
