When anyone builds a multiparty video chat application they pretty quickly run into the issue of how to lay out the many different participants. You want everyone to be visible to everyone else and you also want video to take up as much space as possible, without wasted white-space. In the web you have the additional complexity of lots of different display sizes. Participants can be on a mobile device or tablet, or even just resizing their browser window so that they can see something else beside the video chat. For this reason you want a layout algorithm that is responsive.
Our good friend Philipp Hancke wrote a great post recently on a WebRTC audio bug that has been plaguing Chrome on MacOS for the last few years. The issue presented itself as the microphone not working sometimes in Chrome on MacOS until you completely restart the machine. This seemed to happen after a Mac went to sleep and then woke up again.
The good news is that this is fixed with Chrome 63! Philipp put together a great chart showing the error rates in different versions of Chrome which clearly shows the drop off with Chrome 63.
Did you know that not all live video streaming is created equal? And the event that you thought you were watching “live” may actually have happened over a minute ago?
That’s because the most popular live video streaming protocols such as HLS and RTMP, whilst often described as “real time”, are subject to encoding, transmission and then decoding. Each of these processes introduces a delay before you get to feast your eyes and ears on the glorious content.
When I was a kid, the encyclopedia was the entry point for learning about any topic.
Now with Wikipedia, the world’s knowledge is available for anyone anywhere in the world with an internet connection. This is great for learning about a great many topics. But what about learning a new language where conversation practice is critical? And what if you want a native speaking tutor? Enter Education Technology (EdTech) live video solutions powered by the OpenTok global infrastructure.
As we continue to work towards enabling developers to reap the full potential of WebRTC, we wanted to demonstrate connecting a WebRTC audio stream with a PSTN user, using OpenTok SIP Interconnect and a third party SIP-PSTN Gateway.
When you sign up for a new platform, we know it can sometimes be overwhelming. It can be a challenge to know what information to seek out and simply how to quickly get started building your first project to become successful with the platform. At TokBox, we’ve received positive feedback on our developer documentation and resources, and we wanted to further streamline the development process with our platform to accelerate the path to production.
When talking about game development, there is one name that quickly comes to mind. Unity has become one of the most popular engines that you can use if you plan to develop a game. Its multiplatform capabilities and ease of use makes it a good solution to bring your idea to life.
Like any other type of application, adding live communication features to a game is not a trivial thing. There are plenty of complicated problems to solve. OpenTok comes to the rescue in most scenarios and adding video chat to Unity game development is no exception.
When I introduced myself at the start of October, I shared my aim of working with TokBox developer community members to maintain and add support for third-party frameworks in order to reach as many developers as possible. I’ve been busy since then speaking to our community and learning about what they need to have a great experience with our OpenTok platform and get creative with live video.
As part of our 2.12 client release, we were delighted to graduate our OpenTok Windows Client SDK out of beta and make it generally available. In addition to being a standard client endpoint for the OpenTok platform, the Windows SDK makes it easier to go beyond regular video chat and create whole new level of collaboration experiences.
Creativity & magic
The creativity of developers never ceases to amaze me and when you provide developers with powerful tools like our Windows Client SDK, magical things happen. A few weeks ago, I was fortunate to speak to the team at Calgary Scientific. Calgary has two major divisions: one in health care called ResolutionMD, and another focusing on cloud collaboration and mobility called PureWeb. Specifically, I spoke to them about their innovative collaboration plugin for the Rhino3D CAD tool, called PureWeb Cast, which has launched in beta today.
Picture this: you are outside in a park and attending a meeting using your Android phone with a cool OpenTok-based application, but suddenly you need to check some information from a different app on your phone. Currently, your only option would be to put the original app in the background, and stop seeing the rest of the people in the meeting while you check that information.
