GUEST POST: WebRTC.ventures is a custom design & development agency focused on building WebRTC applications. They are part of AgilityFeat, which is one of our development partners at TokBox. Jean Lescure from their team wanted to share their experiences using our new API for detecting call quality.
Back in August TokBox announced their new Pre-Call API, for testing out bandwidth conditions, and posted a repository on github with a proof of concept. At WebRTC.ventures we saw a great opportunity to build upon that project and got working on creating a demo app out of it, including a server implementation in NodeJS which is compatible with Heroku.
As 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.
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.
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
At TokBox we are focused on making life easier for developers and accelerating their development time. We understand that our partners build very complex solutions, and they need our communication expertise and toolkits. Today we are excited to introduce Starter Kits for the OpenTok platform. These include sample code and design and development best practices for implementing the OpenTok platform’s server and client components. Now you can give your development a jump start, but still have the flexibility you need to to customize your implementation however you want.
