    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.

This quick tutorial will build on the previous one, showing you how to add a volume slider to the audience side of your application.

    An important aspect of running a Twilio Live streaming experience is to track your viewership. But how do you do that? There are many different ways to do it, and the best method to use will depend on your needs and your technology stack.

    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, …
