Introducing the One-to-One Sample App

tokbox-inc_markWe’re excited to announce the release of the OpenTok One-to-One Sample Application across web, iOS and Android.  This open-source application enables you to speed up your development efforts to set up interoperable, production-quality audio/video communication between users.

As you get started with this OpenTok sample, you will learn the best practices used to develop and manage the audio, video, and camera elements on mobile devices or in the browser. We recommend this is as your first step in delivering Real Time Communications (WebRTC) solutions on the OpenTok platform.

Lip-sync Issues: When a Chrome Update Fixes your Application

This post was co-authored by Gustavo Garcia Bernardo, Philipp Hancke and Charley Robinson.

When WebRTC stuff is really broken, it gets fixed very quickly.

Early in December 2015, shortly after the release of Chrome 47 to the general public, we started to notice a subtle and strange behavior in the Audio/Video of streams during our many daily meetings using WebRTC: the video occasionally wouldn’t stay caught up with the corresponding audio. As with many bugs noticed internally by developers, it took a while for any of us to believe that what we were seeing was a real issue. We call this the inverse of productive dogfooding: rather than assume we are just like our users, we can just as easily decide we are nothing like them.

How to get a WebRTC Diagnostic Recording from Chrome 49+

WebRTC logoHave you ever had to support a WebRTC application and needed to get packet dumps from the user? Wireshark is a great tool for this, but asking a user to install it and make a dump rarely works. It’s just too complicated. So I was pretty excited when I read the Chrome 49 release notes which described (not in much detail) a new feature called the ‘RTC event log’. This is described as follows:

We now provide a new debug option in chrome://webrtc-internals for tracing internal details (e.g., BWE, jitter buffer state) for audio and video sessions. This option creates a log containing the timing and headers of packets as well as the timing of various internal events. We hope this will help resolve issues related to media transport and jitter buffers; attaching this log when reporting such issues will help us tremendously.

The optk Developer Command Line Utility

tokbox-inc_markWhen I’m working on developing an OpenTok application, I want to move fast. As a software engineer, I have loads of little workflow shortcuts, scripts, tricks, and favorite tools. When I started to build optk, I wanted to shave off just a couple seconds off of something that I had to do dozens of times a day.

I usually start my OpenTok project building the client, whether that be using the OpenTok JavaScript SDK, iOS SDK, or Android SDK. A button here, a label there, fill out the menu, and then add some WebRTC-powered streaming goodness. At that point I’m not worried about how Sessions and Tokens are going to be generated, that’s a concern for my server, and I’ll solve that after I have some basic tangible UX.
