    8 Things Product Owners Should Consider With Video Apps 8 Things Product Owners Should Consider With Video Apps

    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. Still, when building a live video application, there are important things that a product owner should consider.

    Below, I’ve shared 8 items that other product owners and leads should consider when using video in their application.

    8 video app considerations for product owners

    Let’s look at the top items you should consider with your video applications.

    1. End-user demographics

    Who will use your video application determines a lot, including how to design it and other important features.

    Is your application going to be used by medical professionals or techies? Does your user base consist of Baby Boomers or Generation Z? Each of those …

    One Year of WebRTC Go: Highlights, Updates, and a Special Announcement on Quota Increases One Year of WebRTC Go: Highlights, Updates, and a Special Announcement on Quota Increases

    We launched WebRTC Go a year ago to make it easier for developers to get started with WebRTC. We’ve seen tremendous growth and interest from the community, and based on feedback from our WebRTC Go developers, we are excited to announce quota increases to allow developers to build 1:1 video applications in production for free, for longer. The changes are as follows:

    1. WebRTC Go now comes with unlimited TURN usage, removing the previous 25 GB/month limit.
    2. You can now scale up to 500 concurrent participants or rooms, up 500% from the previous limit of 100.

    If you missed our launch last year, Twilio WebRTC Go provides developers with a toolkit to build, launch, and run 1:1 video applications for free. With WebRTC Go, you don’t have to worry about gathering ICE candidates and relaying media — we provide the signaling and STUN/TURN servers for you. You also get SDKs, quickstarts, …

    Share a File over a WebRTC Data Channel with Twilio Video Share a File over a WebRTC Data Channel with Twilio Video

    When you're taking part in a video conversation, sometimes you have files you want to share with the other people on the call so that everyone can take a look. This is a great way to collaborate with your friends or colleagues when you're not in the same room or looking at the same screen.

    In this tutorial, you'll build a video application with JavaScript and learn how to use the Twilio Video DataTrack API to share a file over WebRTC with the other participants on the call.

    Follow along below step by step, or if you're interested in skipping ahead to take a look at the code, visit the project repository on GitHub here.

    Accelerate Your Development with the New Video Room Monitor, Now in Beta Accelerate Your Development with the New Video Room Monitor, Now in Beta

    Whether you are just starting to build with Twilio Programmable Video or are looking to optimize your application in production, access to the inner workings of your video application is essential to iterate fast and verify code changes to lead to the outcome you are looking for. You could dive into the Room object through the browser console, but the values are not updated in real-time, and it often takes many clicks to find the value you want. Furthermore, some of the metrics you need for optimizing your application aren’t easily consumable. For example, although you can get the total bytes sent for a given track after some number of clicks, what you probably want is the bitrate. And you probably want to see how it changes in real-time. As you go through the various stages of development, this process becomes cumbersome and the time it takes to access the …

    Help Your Users Help Themselves with the New Video Diagnostics App, Now in Beta Help Your Users Help Themselves with the New Video Diagnostics App, Now in Beta

    The reality when building and operating real-time video applications is that sometimes the device, software, and network conditions of your end users, variables seemingly outside your control, can negatively impact their perception of the quality of your video service. Thus, to help your customers have high-quality video experiences, it is important to take the necessary steps to ensure users are set up to have a successful first video call experience during onboarding or to be able to quickly diagnose end users' issues when they arise.

    To help you with this, we are excited to announce the release of the Video Diagnostics Web App, an open source ReactJS application demonstrating how to test a participant’s ability to have a high-quality video call with the Twilio platform - now available in Public Beta for WebRTC Go, P2P, and Group room developers. It can be used as part of onboarding or as …

    Improve the Efficiency of Your Multi-Party Video Experiences Improve the Efficiency of Your Multi-Party Video Experiences

    A good multi-party video experience is critical for education, social, and workplace collaboration use cases, so that everyone can be part of the conversation. While the value is clear, building a performant multi-party video application for a browser or mobile device is hard. You need to create a video UI that is intuitive for your users that also delivers a great experience regardless of the device and type of network they are using.

    In 2019, we introduced the Network Bandwidth Profile API to help developers allocate bandwidth to specific participants based on the use case. Today, we are delighted to introduce the new and improved Network Bandwidth Profile API to empower developers to create multi-party applications that are more efficient with both bandwidth and CPU. This efficiency prevents users' computer fans from going haywire, improves video quality, and reduces the support burden on developers. In addition, this update provides fine-grained …
