Chrome 23 Beta adds more media muscle (click for full article) Oct. 3, 2012 (12:40 pm) By: Lee Mathews "Google has been steadily building out WebRTC functionality in Chrome ever since it first surfaced in the Developer Channel in January. Just this week Chrome 23 graduated to the Beta Channel, bringing with it even more features that integrate with the open source multimedia communication standard. Two new APIs - PeerConnection and MediaSource - are ready for developer use. MediaSource gives developers a way to dynamically adapt video playback in their web apps to compensate for changing computer and network performance. It's designed to prevent bothersome buffering and falls back to reduced quality rather than losing a feed altogether. Google's posted a slick demonstration over on the WebM projcet site that lets you keep tabs on network performance as you watch a video clip from Sintel, another one of the Blender Foundation's open animation projects. PeerConnection is designed to make it easier for developers to create audio and video chat apps on the web, and it's closely tied to the getUserMedia API which recently added plug-in free access to a user's webcam. Another addition to the new Chrome Beta is support for the track element. Track gives developers a simple method for adding all kinds of supplementary text to an HTML5 video, from subtitles and captions to dynamically-generated location information. If you're lucky enough to hit this demo site when there's bandwidth available, you can see track in action as it's used to display Google Maps metadata over the video feed from a bike ride. All these multimedia features are lining up to make Chrome the go-to choice for smooth, standards-based video experiences on the Web... but since they're all open source, it's a safe bet that other browsers that have chosen to support WebRTC (like Firefox and Opera) will reap the benefits, too.
