Introducing Pre-Call Test: Stand up to spotty network conditions

WIFI-IconAs much as WiFi and cellular network reliability has improved over the years, it’s not uncommon to find yourself in a situation where connectivity drops or is spotty at best. Somehow in our overconnected world, “offline” mode still exists. When you’re using real-time communications technology, poor service or connection quality can be particularly disruptive.

That’s why we’re excited to introduce our Pre-Call Test tool – a set of tools that will determine if an end-user’s OpenTok-powered call with be successful given their network conditions. The Pre-Call Test can be integrated into your application’s workflow so that your end-users can run the diagnostic test before they even join the session. Based on their test results, you can implement business logic that determines whether a particular user is allowed to publish a stream to the session with video, audio-only mode, and more.

Demo application: OpenTok 3D

OpenTok3dtest

The OpenTok.js SDK integrates beautifully into current HTML elements, providing a great variety of layouts and styles. But why should we stick to the traditional 2D design? Modern browsers offer us the power of 3D visualization with WebGL, a technology that has already opened up a new world of interaction and presentation of data within the browser domain.

With an objective to take advantage of the possibilities of 3D within the browser,  we created the  OpenTok 3D demo. The OpenTok 3D demo is a multi-party video application which shows how we can integrate the OpenTok.js API with WebGL technology using the three.js library. One of the objectives of this demo application is to inspire people building on top of the OpenTok.js SDK, showing them the beginning of endless possibilities on how we can present the video screens in a true 3D world.  Cameras, lights, textures, rendering effects, and more, can be leveraged to enrich the final experience.

Using Angular JS with OpenTok

AngularJSBlogIntroduction

We’re big fans of Angular JS at TokBox and we have been using it internally to build applications for quite some time. It’s a fantastic framework for building Single Page Web Applications – since all OpenTok Applications are Single Page Web Apps they work really nicely together. This post is going to be based largely on our experience writing meet.tokbox.com, our own video meeting tool we use internally. The code for meet.tokbox.com can be found at https://github.com/aullman/opentok-meet

Generating Tokens without Server Side SDK

During AngelHack, Alexander Ramirez came up to me with a puzzle. “How do I generate sessions and tokens?” He asked. Normally, I would have told him to use one of our server side SDKs, but he was building a browser plugin with video chat and wanted to use our REST API instead. Getting the SessionId is easy, it’s a simple POST request. However, generating token is not so straightforward because it is generated algorithmically. This tutorial will show you how to generate a token, and examples used here will be written in JavaScript.
