![]() ![]() ![]() ![]() For more information see the WebRTC Tab Content Capture proposal. Very useful for sceencasting and web page sharing. This makes it possible to capture the visible area of the tab as a stream, which can then be used locally, or with RTCPeerConnection's addStream(). Tab Capture is now available in the Chrome Dev channel. Likewise the error if you try to use getUserMedia from the local file system, not on a server! # Streaming screen capture Here's a screenshot of DataChannel running in Firefox: DataChannel in later versions should be more stable and will be implemented so as to enable interaction with DataChannel in Firefox.įirefox Nightly/Aurora supports mozGetUserMedia, mozRTCPeerConnection and DataChannel (but don't forget to set your about:config preferences!) This will be for experimentation only, may not be fully functional, and communication won't be possible with the Firefox implementation. The API is simple-similar to WebSocket - but communication occurs directly between browsers, so DataChannel can be much faster than WebSocket even if a relay (TURN) server is required (when 'hole punching' to cope with firewalls and NATs fails).ĭataChannel is planned for version 25 of Chrome, behind a flag – though it may miss this version. # DataChannelĭataChannel is a WebRTC API for high performance, low latency, peer-to-peer communication of arbitrary data. WebRTC has also now been implemented for desktop in Firefox Nightly and Aurora, and for iOS and Android via the Ericsson Bowser browser. When the standards process has stabilized, the webkit prefix will be removed.) Other names and implementations have been deprecated. (A word of explanation about the name: after several iterations, it's currently known as webkitRTCPeerConnection. There's an ultra-simple demo of Chrome's RTCPeerConnection implementation at /pc and a great video chat application at. TURN server support is available in Chrome 24 and above. WebkitRTCPeerConnection is now in Chrome stable and it's flagless. Take a look at the cross-browser demo of getUserMedia at /gum - and check out Chris Wilson's amazing examples of using getUserMedia as input for Web Audio. GetUserMedia is available now in Chrome with no flags, as well as Opera, and Firefox Nightly/Aurora (though for Firefox you'll need to set preferences). In particular, we're really excited to see WebRTC arriving on multiple browsers and platforms. A lot has happened with WebRTC over the last few weeks. ![]()
