Today we’re proud to announce our latest WebRTC innovation: Mantis, a cloud-scaling infrastructure for our OpenTok on WebRTC platform.
This is another big step forward for the TokBox team as we continue to pursue our goal of providing application developers with simple yet powerful APIs. APIs that not only leverage the latest standards to deliver the best possible experience, but that are backed by a scalable, smart cloud which supports interoperability across a variety of end-points.
A new version of Chrome is out, and with it changes in the WebRTC stack. We dug through the commit logs for Chrome 26, and found the following list of WebRTC bug fixes, enhancements, and updates that we thought were relevant to the OpenTok community:
- A lot of audio bugs in WebRTC were fixed dealing with crashes and non-standard audio bitrates
- Chrome on Android can now be WebRTC-enabled by enabling a flag
- Improvements to the connectivity stack in WebRTC
- Ability to set media constraints for audio
On February 4th Mozilla and Google announced that their respective browsers could now talk to each other via WebRTC. This is another big milestone in WebRTC’s path towards becoming available in all modern web browsers, albeit, today only in an early development build of Firefox, version 21+ (currently Nightly and soon to be Aurora).
We’ve also been working hard on making OpenTok on WebRTC work with both Firefox and Chrome so you too can enjoy all this cross-browser goodness!
Off to the races
The first thing that you need is version 21 or higher of Firefox, currently available through the Aurora FTP site and Nightly site.
About six months ago, Microsoft released an alternative proposal to the W3C WebRTC 1.0 Working Draft, dubbed CU-RTC-Web. Like all W3C groups, the WebRTC Working Group enlists membership from a majority of the industry, including names like Nokia, Cisco, Google, and Mozilla. The most important question raised by the Microsoft proposal is how the Working Group would react to criticism of its draft proposal, and whether Microsoft would accept the published APIs of the Working Group, even if CU-RTC-Web is not adopted. So what exactly does this mean for the development community?
The Microsoft draft outlines a low-level API that allows developers more direct access to the underlying network and media delivery components. It exposes objects representing network sockets and gives explicit application control over the media transport. In contrast, the WebRTC API abstracts these details with a text-based interface that passes encoded strings between the two participants in the call. With the WebRTC draft, developers are responsible for passing the strings between communicating browsers, but not explicitly configuring media transport for a video chat.
Yesterday, the talented folks at Double Robotics rocked the stage at LeWeb in Paris. David Cann, Co-founder and CEO, demoed their telepresence robot, Double. The sleek Double combines Segway-style movement with video presence delivered through an iPad.
Leveraging OpenTok’s iOS SDK on WebRTC, Double enables owners to broadcast their video stream on the robot’s iPad from any location. Not only that, but the operator can stream and control its movements from a smartphone.
Cann demoed the Double’s original inspiration, which was to connect remote workers with their home offices. Calling his CTO back in Sunnyvale, Cann took their Double for a three a.m. spin around the office from Paris. Customers are also finding uses for Double for remote tours of factories, museums, schools, and retail outlets.
