5 Factors to Consider When Choosing Your WebRTC Media Server
If you’re ready to build a WebRTC based live video application, then the most important architectural decision you need to make is what media server to use. A purely Peer-to-Peer (P2P) WebRTC video call does not require a media server. All video and audio media is transferred between the peers, and all your application has to do is establish the P2P connection using a process known as signaling. However, the vast majority of WebRTC applications
Watch WebRTC Live #63: What Have Our Own Experts Learned Lately?
After a successful first outing last year, we again invited a few members of our expert team for a roundtable to share a piece of WebRTC wisdom with our viewers. Who better to learn from than those who work with WebRTC each and every day? Alfred Gonzalez discussed refactoring a WebRTC app to scale. Increasing the number of user connections that an application can handle is an important part of our work. Alfred reviewed the
Configuring Asterisk as a WebRTC SFU Media Server
WebRTC was designed to be a peer to peer communication system. However, it gives rise to a complicated mesh system when the number of participants increases. A Selective Forwarding Unit (SFU) is an alternate topology for connecting through a centralized server to route outgoing media streams from one to many users. Peer to Peer WebRTC Stream Multi-point Peer to Peer WebRTC Stream The multi-party peer to peer party configuration leads to enormous strain on a user

Arnaud Blogs on Twilio about creating a video chat mobile app with Twilio Video and Flutter, using BLoC
Arnaud Phommasone is a talented mobile developer that is a valuable member of our WebRTC.ventures team. He recently wrote a tutorial to create a Flutter app using an unofficial Flutter package for interfacing with Twilio Video, that will allow users to host a call and be joined by multiple other users. Flutter is Google’s free, open-source UI toolkit for building applications for mobile, web, and desktop from one single codebase. The tutorial focuses on creating a
Using DTX for Audio Optimization in Large Multi-Party Calls
In large, multi-party calls there are often just one or two main speakers. The rest of the participants are simply listening with their mic muted. The calls could be updates for shareholders, sales teams, vendors, regional offices, or factories – the use cases are endless. However, also are the number of empty audio packets going back and forth. This can cause a waste of audio bandwidth for silent participants. Handling low bandwidth scenarios to ensure the
Alberto Blogs on Twilio About Issue Diagnostics
It is hard to believe that it was under a year ago that the World Wide Web Consortium (W3C) and the Internet Engineering Task Force (IETF) announced that WebRTC was an official standard. Still, while it is being used by billions to communicate and was invaluable in keeping us connected during the pandemic, WebRTC is still evolving. Developers love Twilio Programmable Video because it simplifies WebRTC usage. But differences between browsers and operating systems can still be

Mariana Blogs on Twilio About Creating Great UX in Telehealth Applications
Building a quality telehealth application is about much more than getting the video to work. It’s about creating a reliable and trustworthy experience between a patient and their healthcare provider. Meeting tools may have the ability to deliver face-to-face video consultations but lack the crucial touch points in a patient's journey that your users deserve. In short: There’s more on the line with a healthcare application, so solid user experience (UX) design is critical. Thoughtful
Pedro Blogs on Twilio About Video App Considerations for Product Owners
Video applications are critical in today’s technology landscape and have played a crucial role in getting the world through the COVID-19 pandemic. Twilio Programmable Video is a great way to get started with building live video apps, in part because it’s straightforward for developers to use. Product owners, in particular, play a key role in their teams’ ability to deliver a high-quality video application. Thinking about items like call quality, waiting rooms, connectivity tests, and call data will
ICE Issues On Restrictive Networks and How To Alleviate Them
Recently, we faced some issues with an on-premise telehealth platform related to connectivity. It reminded us how important it is to keep your eye on the many different types of networks a peer can be utilizing and the subsequent connection issues that can arise in some particular networks. In this blog post, we will review the signaling process and share some tips on how to alleviate ICE issues that can be caused by certain network
The Vonage Conversation API and Telehealth
In a world of remote work, remote medical visits, and remote everything, the concept of completely unified communications is growing quickly. Omnichannel conversations with your bank or your doctor have moved beyond the conceptual phase and can now be implemented in a variety of ways, including via the Vonage Communications APIs. Our team at WebRTC.ventures has been using the Vonage Communications APIs for a long time. We were one of the first development partners for
How to Architect Your WebRTC Application
There is no “one size fits all” application architecture for live video applications using WebRTC. The options vary widely based on your use case and choices between commercial and open-source options for back end services. WebRTC.ventures CEO/Founder Arin Sime and CTO Alberto Gonzalez teamed up at TADSummit EMEA Americas 2021 for a presentation that covered WebRTC architectural considerations and typical use cases based on our team's experience working with a wide range of clients.

Bleeding Unit Tests
Today, with various tools and services available, developing applications with WebRTC can be done very efficiently. For example, CPaaS platforms offer a wide variety of features which abstract the complex details of WebRTC away from the developer. This enables developers to build new features very quickly. However, with rapid development, we have a greater need to maintain the code base. Automated unit tests are very good for this purpose and should be written to verify
Watch WebRTC Live #61: A Fireside Chat on the Future of WebRTC
