    Building a telemedicine waiting room with Twilio Video Building a telemedicine waiting room with Twilio Video

    Telemedicine is rapidly changing the healthcare industry. COVID-19 concerns aside, being able to see a doctor’s face without having to commute is a game changer.

    Twilio Video allows developers to craft HIPAA-compliant telemedicine solutions that are fully under your control and tailored to your patients’ needs. Today I’ll show you how to make a telemedicine app using Twilio Video that lets you show a “virtual waiting room” where the patient can hang out until their doctor arrives. For the sake of simplicity, let’s build the front end in vanilla JS without a framework.

    At a high level, here’s the steps we’ll be following:

    • Set up a back end to control access to the application
    • Set up basic front end scaffolding
    • Build the provider experience
    • Build the patient experience

    For impatient types who want to skip straight to the code, the whole project is on GitHub.

    The Twilio Programmable Video API allows you to build customized video chat applications on top of the WebRTC standard. In this article, I’m going to show you how to add a screen sharing option to a browser-based Programmable Video application built in JavaScript.

    Screen sharing demo

    Tutorial requirements

    In this tutorial we are going to add a screen sharing feature to the video chat application built with JavaScript and Python on a previous introductory tutorial. To run this application on your computer you need the following requirements:

    • Python 3.6 or newer. If your operating system does not provide a Python interpreter, you can go to python.org to download an installer.
    • A free or paid Twilio account. If you are new to Twilio get your free account now! This link will give you $10 when you upgrade.
    • A web browser that is compatible with the Twilio Programmable Video JavaScript library (see below …

    Best Practices for Twilio Video on Mobile Browsers Best Practices for Twilio Video on Mobile Browsers

    Over the last few months, we have seen a surge in interest from developers building video communication web apps for mobile devices. We have worked closely with customers to overcome obstacles inherent in using video in the browser on a mobile device. Based on these experiences, we've compiled a list of best practices so you can avoid the pitfalls and deliver great video experiences in mobile browsers.

    Mobile Browser Challenges

    A  web app running in a mobile phone web browser is the quickest and easiest way to get into a video call. Just click on the web link from a text message or email and you can be in a video call on your phone in seconds - no app install required.

    However, there are some challenges unique to mobile browsers that do not exist with their desktop counterparts. The top gotchas that often catch developers out are:

    Secure your video conference with one-time passcodes How to protect your video conference with one-time passcodes

    As we dutifully practice social distancing, live video conferencing is increasingly popular. From company meetings to yoga classes and magic shows, traditional in person events are going virtual. But while technology connects us, it also comes with privacy and security risks.

    This post will show you how to add one-time passcode authentication on top of your Twilio Video application to ensure that only registered users are able to access the conference.

    While passwords may help protect against war dialing, they don't guarantee that the people joining the video conference should be allowed to participate. A lot of people are still widely sharing Zoom meeting IDs and passwords.

    One-time passcode authentication is useful for gating:

    • Paid content like workout classes, political fundraisers, or live dating shows.
    • Sensitive content with an access control list (ACL)

    This tutorial will walk you through adding Twilio Verify SMS verification to …

    Build a Video Chat Application with Python, JavaScript and Twilio Programmable Video Build a Video Chat Application with Python, JavaScript and Twilio Programmable Video

    The efforts to limit the spread of COVID-19 around the world have forced a large number of people to work from home and this has naturally created a surge in interest for communication and collaboration tools.

    In this article we are going to look at a video conferencing solution, but instead of turning to a third-party system we are going to take the do-it-yourself approach and build our own. Our system is going to run on modern desktop and mobile web browsers, so participants will not need to download or install any software on their computers. The server-side portion of the project is going to use Python and the Flask framework, and the client-side is going to be built in vanilla JavaScript, with some HTML and CSS sprinkled in the mix for good measure.

    If you are worried that this is going to be a long, difficult and obscure tutorial …

    How to add an overlay to your web video chat How to add an overlay to your web video chat

    When building a video chat, Twilio Video provides you with the SDKs and APIs to build video apps that connect your users. However, it is un-opinionated about your interface. With a bit of CSS, we can create effects to make your video chat stand out.

    In this post we'll see how to overlay items like a logo or a user's name over a video. Over the course of the post, we'll turn a plain video into something that looks like this:

    An animation of me on video in my webcam, above me my name appears and to the bottom right a watermark saying "Powered by Twilio" shows.

    Getting started

    To create these effects we won't build an entire video chat. Instead, we'll take the Twilio Video library and use it to get the camera and put it on the page as if it was a video chat – then style that video.

    Create three new files in the same directory to write this application in: index.html, script.js and style.css. Open index.html and fill in …
