OpenTok version 2.15: What’s new and how you can use it

Last week, we released OpenTok v2.15, the latest version of our Client SDKs. We wanted to update you on some of the great new features included and how you can use them.

Audio Enhancements in Web and Windows SDKs

In opentok.js 2.14 we added the ability to switch cameras using the Publisher cycleVideo() method which was really well received. Version 2.15.0 of opentok.js and our Windows SDK add the ability to switch to a different audio source. In opentok.js you do with using the Publisher setAudioSource() method and in Windows you use the AudioDevice.SetInputAudioDevice method. The obvious use-case for this API is to allow your users to switch microphones without needing to create a whole new publisher. But it can also be used to switch to other supported audio sources, for example loading audio from an audio file, or creating custom audio. In opentok.js you do this using the setAudioSource() method and passing a custom audioTrack. In the Windows SDK you do this using the AudioDevice.setCustomAudioDevice method and passing a custom audio driver.

Integrating WebRTC with PSTN using OpenTok & Nexmo SIP

Integrating WebRTC with PSTN using OpenTok & Nexmo SIP

In this blog we look at how to connect OpenTok Live Video sessions with traditional PSTN phone calls. We will demonstrate how to connect an OpenTok session to PSTN with an audio stream that connects through OpenTok SIP Interconnect to a Nexmo SIP-PSTN Gateway.

OpenTok SIP Interconnect is a general purpose SIP capability that can be used to connect to many different kinds of gateway or other SIP systems. TokBox is now part of Vonage, so in this blog we will use our own Nexmo programmable communications APIs to bridge the call.

How To Get the Most out of the New Account Dashboard

In April, we announced updates to our pricing and packaging, which allows TokBox customers to have more flexibility with the ability to add-on features a la carte to their accounts.

Today, we’re excited to announce that we’ve made several improvements to the Account Dashboard, which provides users with more self-service functionality.

Speed Up OpenTok Session Debugging with Inspector

OpenTok Session Debugging with the Inspector tool

Diving into data on OpenTok sessions can provide developers with the tools they need to understand bugs and make improvements quickly. That’s why we built Inspector – a tool to help developers understand what happened in specific OpenTok sessions. Users can either enter a session ID or use the Session Dashboard to access the information. This includes user data, errors, video and audio quality and events about a session.

Build an AR App with the Frame Metadata API

AR App using Framemeta Data API from OpenTok

If you had to choose one memorable thing about the upcoming iOS 12 when it was unveiled at WWDC’18, it would probably be the inclusion of ARKit 2.0, Apple’s Augmented Reality toolkit for iOS. I bet you still remember that cool demo by the Lego guys playing on the stage.

In fact, ARKit is probably the component which is going to grow the most in the new version of iOS, with many new features, improvements and even a new app to easily perform real-world measurements.
