We are proud to announce Programmable Video Javascript SDK 2.0 is generally available!

With this new release, we introduce features to uplevel the quality of your Video applications which include, Track Priority and Network Bandwidth Profile API, Region selection, and Reconnection State & Events.

Programmable Video JS SDK 2.0 gives you the building blocks and tools needed to build web based multi-party Video Chat applications. The SDK hides the inherent complexities of Voice, Video, and data communications, which comprise signalling, media exchange, and network traversal to let you focus on providing the user experience your customers will love.

Just like the 1.x version, Programmable Video JS SDK 2.0 is based on WebRTC and is supported on the most popular desktop and mobile browsers including Chrome, Firefox, Safari, and Chrome Edge. Video JS SDK 2.0 supports the same features in 1.x including Dominant Speaker detection, Network quality …

We are excited to announce Twilio Voice & Video Javascript SDKs now support Microsoft’s new Chromium based Edge Browser aka Edgium. Now, your application can run on Microsoft’s latest incarnation of its Edge browser without you changing any of your existing Twilio Voice or Video[1] Javascript SDK code.

The new Microsoft Edge is built on the Chromium open source project which also powers Google’s Chrome browser. With Microsoft adopting Chromium, developers will benefit from spending less time on interoperability because of seamless webrtc integration with other popular browsers including, Chrome, Firefox, and Safari, and has reduced the potential for security related issues.

We put the browser through hundreds of automated tests and verified all our internal apps work as expected. Furthermore, Microsoft Edge performed just as well as Google’s Chrome browser, using a similar amount of RAM and CPU.

At Twilio, our priority is to support the most popular …

Realtime user interaction is a great way to enhance the communication and collaboration capabilities of a web application. Video chat is an obvious choice for sales, customer support, and education sites, but is it practical to implement? If you’re developing with Angular on the frontend and ASP.NET Core for your server, Twilio Programmable Video enables you to efficiently add robust video chat to your application.

This post will show you how to create a running video chat application using the Twilio JavaScript SDK in your Angular single page application (SPA) and the Twilio SDK for C# and .NET in your ASP.NET Core server code. You’ll build the interactions required to create and join video chat rooms, and to publish and subscribe to participant audio and video tracks.

This post provides instructions and code for creating a video chat app with ASP.NET Core 3.0. To learn how to build the …

The Twilio Programmable Video team is excited to announce that the Track Subscription API is now generally available. Before this release, video participants were automatically subscribed to all tracks. Now, developers can define which participants receive which tracks and control dynamically what end-users see and hear. This new API is available in Group Rooms, Twilio’s solution for multiparty video conferencing.

In this post we outline how we’ve improved the Group Rooms subscription model and share how to get started with the Track Subscription API.

To date, Group Rooms have enforced a subscribe-to-all model. This means that participants automatically subscribe to all the tracks and receive all the audio and video information published to the Room without the choice of opting-out. While this works for most collaboration applications, there are situations where there is an opportunity to provide improved participant experiences. These include:

• Subscribe-to-one: Participants subscribe only to a presenter’s tracks. …

We've seen a video chat built in React on this blog before but since then, in version 16.8, React released Hooks. Hooks let you use state or other React features inside functional components instead of writing a class component.

In this post we are going to build a video chat application using Twilio Video and React with only functional components, using the useState, useCallback, useEffect and useRef hooks.

What you'll need

To build this video chat application you will need the following:

• Node.js and npm installed
• A Twilio account (sign up for a free Twilio account here)

Once you've got all that, we can prepare our development environment.

Getting started

So we can get straight to the React application, we can start with the React and Express starter app I created. Download or clone the starter app's "twilio" branch, change into the new directory and …

We are thrilled to announce that the Network Bandwidth Profile API is now available via Public Beta: a Programmable Video API designed to improve the quality of experience in Group Rooms. Before this release, video bandwidth was split equally between tracks, which meant that lower and higher priority tracks received the same treatment. Now with this release, developers can specify how the available network bandwidth is allocated, reallocate bandwidth to higher priority tracks, protect audio quality, and optimize battery and network resources consumption.

Why a Network Bandwidth Profile API?

Programmable Video Group Rooms are based on an SFU (Selective Forwarding Unit) architecture. This means that participants publish audio and video as independent tracks to the SFU server, which in turn routes them to the rest. Hence, the number of subscribers tracks per participant grows as N-1 where N is the total number of participants.

The SFU can control the quality …

A few months ago we announced Twilio Programmable Video Network Quality API: a simple mechanism enabling end-users to be notified, in real-time, about their network quality using a 1-to-5 scale as a measure. Our developer community is incredibly important to us; we have been working hard to address the feedback you’ve provided since the launch. Today, we are thrilled to announce an enhanced version of the Network Quality API. Based on your feedback, we’ve released new features that enable broader quality monitoring and diagnostics.

Before delving into the details of these new features, we’d first like to share with you the feedback that influenced these updates. We will then outline what has changed and how to use these enhancements in your work.

Developer Feedback on Programmable Video Network Quality API

To explain why we’ve implemented these new features, we’d like to recap what we learned from our developer community: …

Realtime user interaction is a great way to enhance the communication and collaboration capabilities of a web application. Video chat is an obvious choice for sales, customer support, and education sites, but how can you quickly implement it? Twilio Programmable Video enables you to efficiently add robust video chat to your applications, whether you are using a JavaScript Model-View-Controller framework like Angular or server-side templates.

This post will show you how to create a video chat application using the Twilio JavaScript SDK in your Angular single page application (SPA) and the Twilio SDK for C# and .NET in your ASP.NET Core server code. You’ll build the interactions required to create and join video chat rooms, and to publish and subscribe to participant audio and video tracks.

Prerequisites to a Angular and ASP.NET Core Video App

You’ll need the following technologies and tools to build the video chat project described in …

Before eLearning, a student needed to commute across town or even move to a different country to get a quality education. Improvements in technology, especially in WebRTC, has taken the hassle out of connecting students with great teachers and schools.

I’m Alex from LearnCube, virtual classroom software that specializes in helping language-learning and academic tutoring companies teach online.

When we started four years ago, we made a bet that WebRTC would be the video technology of the future. Users much prefer the seamless experience of not having to download an external app or software. The quality has been getting better every year and it’s already superior to many many established video-conferencing providers.

We became a Twilio customer for Programmable Video in late 2017 after learning that Twilio had acquired Kurento. What we found was a quality video platform to embed in our virtual classroom software at an affordable …
