Whether you’re developing a new website, building an app for mobile or working out web infrastructure, it’s important to keep up to date with all of the technologies contributing to the evolution of the web. The O’Reilly Fluent Conference aims to to help you do that. With a range of speakers across a number of different roles and industries Fluent covers the full scope of the Web Platform and its associated technologies.

TokBox at the Kranky Geek WebRTC Show, India
As the WebRTC landscape continues to evolve it can be hard for developers to keep up. The Kranky Geek WebRTC event aims to fill in the gaps and jumpstart your knowledge about WebRTC and the ever-changing landscape of communications online.
The event has a jam-packed agenda with experts talking about a range of different topics from the very basics to real world applications, and building workshops. TokBox CTO, Badri Rajasekar, will be there to talk about the need to push the boundaries of WebRTC in order to cater to unprecedented broadcast use cases.
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+
Have 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.
When a Chrome update breaks your WebRTC application
Early December saw the roll-out of Chrome 47. When doing anything with WebRTC, this is always an interesting time. A release brings new features or may break things, like removing the getUserMedia functionality for insecure origins.
Our metrics clearly track such roll outs as seen below:
TechTok catch up – WebRTC codec wars: rebooted
At our September TechTok WebRTC consultant and analyst, Tsahi Levent-Levi, came along to discuss the power plays of the video coding industry.
Just when we thought we were done with the video codec wars in WebRTC – we found out we’re only just beginning. Tsahi was here to talk us through some important questions – how is this WebRTC codec war going to play out? Where do the alliances lie? And where are we headed?

The impact of Google’s new Chrome security policy on WebRTC
UPDATE 9/16/15: After we published this post Google announced that they are pushing back the release date of the HTTPS security change. They’re estimating that it will now be released to production in December 2015.
Google recently announced a security policy change that will impact future versions of the Chrome browser. Any website which has integrated geolocation technology, screen-sharing, WebRTC and more, will now be required to be served from a secure (HTTPS) site.
We at TokBox are supportive of this update as we believe operating your WebRTC-based applications through HTTPS is a best practice and offers enhanced security. In addition, it has the added bonus of improving your end-user experience by remembering their hardware settings, and even allowing screen-sharing (if you choose to implement it).
Koding- making it easy to collaboratively code
The Internet has fundamentally reshaped the world of work. Emails, instant messaging and video conferencing first transformed the way we communicate, and today as we increasingly move into the cloud, nearly every aspect of work takes place online in a globally connected 24/7 environment.
The physical office space as we knew it has become less relevant and an increasing number of employees are working from home or remote locations. Startups and even the most well established global firms, are realizing the benefits of flexible work and are embracing communication tools that enable teams to connect and collaborate effectively online (eg. Slack, DropBox).
SF WebRTC meet up
Last week TokBox hosted the monthly SF WebRTC meet up at our offices in San Francisco.
It was a great evening, with a range of speakers and topics from the WebRTC world. This month we heard from:
- Ankur Oberoi from Tokbox
- Hadar Weiss from Peer5
- Feross Aboukhadijeh from WebTorrent, PeerCDN
- Dr Alex from Temasys
You can watch a full recording of the event below and if you are interested in hearing more about meet up events at TokBox, you can join our meet up group here.
Webinar: How to Build Multi-Party Calling with WebRTC
WebRTC is maturing and we can see the needs in the market evolving along with this.
However, with the increased need for rich, digital experiences comes the challenge of building more advanced applications. We know that building real-time video communications can be challenging, especially when it involves more than two participants. To pull off a multi-party call using WebRTC off-the-shelf you’ll need a strong backend infrastructure and a deep understanding of media processing. That’s why we are looking forward to exploring this topic with WebRTC expert, Tsahi Levent-Levi, founder of bloggeek.me, in our upcoming webinar.
