mobile multiparty OpenTok

Looking at the top charts of your favorite mobile app store you’ll find two kinds of apps, games and social apps. Without a doubt, social platforms are where you’ll spend a big chunk of your internet time.

The way we interact on these social platforms has been evolving since they first appeared on the screen. Whilst in the early days you couldn’t expect much more than simply exchanging text messages with other people, the evolution of several technologies has led to users expecting richer ways of communicating.

WebRTC on Safari Developer Workshop

WebRTC on Safari Developer Workshop

We continue to be excited by the customer use cases that WebRTC on Safari will enable, especially the “spontaneous” customer interaction situations we see in Retail and eCommerce, Customer Service and regulated industries – as we discussed in our previous blog. On June 22nd we held a WebRTC on Safari Developer Workshop in San Francisco to make more information available to local developers about the details of the Apple announcement and how to get started experiencing and developing WebRTC apps for Safari 11.

We are pleased to now provide this information online for everybody!

The OpenTok Platform, Now for Safari 11 in Beta

OpenTok.js SDK with support for Safari 11 in beta

NEWS: In the San Francisco Bay area? Come to our Developer Workshop on WebRTC in Safari on June 22 @6pm.

Today we’re rolling out an exciting new beta – the OpenTok.js SDK 2.12. With this release developers can begin building beta projects that are compatible with Safari 11. That’s right, WebRTC is available in Safari in beta.

Given the large number of devices running the Safari browser, this not only provides broader device reach for TokBox customers once it releases to general availability, but introduces a new set of use cases for browser based video chat on iPhones and iPads. On Monday our CEO Scott Lomond wrote about what this development means for WebRTC. Our goal today is to help you understand how you can start leveraging the OpenTok platform and WebRTC in the Safari beta.

Why We’re Excited About WebRTC Support in iOS 11 and Safari

WebRTC support in iOS 11 and Safari

NEWS: In the San Francisco Bay area? Come to our Developer Workshop on WebRTC in Safari on June 22 @6pm.

I’ve been waiting a long time to be able to publish this blog post. It was easy to miss, but if you were paying close attention to today’s WWDC keynote you would have seen Apple indicating WebRTC support for iOS 11, which will be available later in the year.

From the early days of WebRTC in 2011 until yesterday, the single biggest outstanding question about this standard had been when will it be supported in all major browsers? Supporters could see that WebRTC was loaded with the potential to change how we use communications, but there was always that lingering sense that WebRTC wouldn’t cross over to the mainstream and be used for mission critical applications until it was supported by all browsers. With today’s iOS 11 announcement, Apple has answered this question. WebRTC is here to stay. This is a major turning point for embedded communications.

New Custom Layout Controls for Content Creators

In addition to powering live video experiences, TokBox is also in the business of making it simple to create content. Whether it’s for a social live stream that is delivered to millions of viewers, or a webinar recorded for post-event distribution, the OpenTok platform makes it possible. 

There is no one-size-fits-all video layout that accommodates this wide range of use cases. You wouldn’t use the same UI/UX for a broadcast app as you would a customer service app, right? Developers using our platform need adequate control and flexibility to create UI/UX optimized for their experience. 

For this reason, we’re excited to release new REST APIs to customize video layout for content creators using the Archiving API and Broadcast API for HLS & RTMP. Now developers using these two features can create a custom layout using CSS, or select one of the following prebuilt layouts:
