This could be a link to a document, or even a reaction emoji. In this article you are going to learn how to take your video application to the next level by adding a chat room with the Conversations API.

    Tutorial requirements

    This is the third article in my series of Programmable Video tutorials, so we are going to take advantage of the video chat application built in the previous two installments and add the chat room feature to it. This application uses a vanilla JavaScript front end and a Python back end. To run this application on your computer you need the following requirements:

    Add an Interpreter to a Telehealth App with VOYCE and Twilio Programmable Video VOYCE Interpreter Telehealth Room

    Xiang Xu from VOYCE joins us today for this guest post on how to add VOYCE’s interpreter capabilities to a telemedicine waiting room and video chat app.

    VOYCE provides remote video interpretation services to the health care, legal, and business communities. Our professional, qualified, and medically trained interpreters service 220+ languages and dialects. Our platform can tightly integrate with Twilio Programmable Video and Programmable Voice.

    This post will show you how to add VOYCE’s interpretation services to a Twilio Programmable Video telemedicine room. A medical provider can add an interpreter to the room with a single click of a button.

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

    • Generate a Twilio Video token for a VOYCE interpreter
    • Set up a basic front end user interface for the VOYCE service

    Extend the React Quick Deploy Video App with DataTracks header - Extend the React Quick Deploy Video App with DataTracks

    In March, Twilio released quick deploy video apps for three different platforms - React.js, iOS, and Android. These apps are fully functioning video collaboration apps that can be deployed to the cloud in minutes. They serve as a canonical reference for developers building out their communication solutions by showcasing the features and capabilities of Programmable Video.

    When you build a video app, you can get pretty far with just audio and video. But what if you want to go above and beyond audio and video to build more engaging video experiences by adding hand-raising, annotations, whiteboarding, and more?

    The answer is DataTracks. With Twilio Video, you can use DataTracks to send real-time ephemeral data such as text, JSON, or binary data to other participants in a video call. We say the data is ‘ephemeral’ because it isn’t persisted anywhere. If you aren’t in a room when …

    Announcing Twilio Video WebRTC Go: Build and Run 1:1 Video Apps for Free Twilio Video WebRTC Go: Build and run 1:1 video apps for free

    As we’ve all personally experienced, many face-to-face interactions have been replaced with virtual ones, over video. There are new use cases popping up every day from virtual court, to remote clienteling, to house viewings. That’s because more and more developers are looking to build video apps.

    Customers such as MDLive are building telehealth applications, making healthcare more accessible. In the education space, Air Tutors is making tutoring more engaging with virtual whiteboards, annotations, and animation to bring subjects such as math to life.

    At SIGNAL, we are announcing that Twilio Video WebRTC Go will be generally available. This is a 1:1 experience that developers configure and use with our Video JS, Android, and iOS SDKs. It’s a developer toolkit that removes the complexity of building directly on top of WebRTC. Not only is it generally available, it's also free. This is not just a free trial.

    Creating memorable moments with Twilio Video Creating Memorable Moments with Twilio Video

    Humans are inherently social beings and communication is at the core of these connections.  Twilio provides developers with a wide array of channels, from voice, to messaging, email, to SMS, and of course, video.

    While consumers have been gravitating towards video in social media for quite some time, organizations are now adopting video at a much higher velocity. A study by Twilio showed that the pandemic accelerated digital transformation at companies by 6 years. That same pattern is playing out with Twilio Video. While not a material portion of Twilio's business, Twilio Video has experienced a 540% year-over-year increase in weekly minutes compared to this time last year.

    This year, Twilio invested in new Video features and we’ve seen adoption by a range of customers including Telehealth, Education, and Virtual Visits. What has made our customers successful is that they’ve created customized video applications centered around user experience. …

    Providing users with the ability to switch between the speakerphone, earpiece, or headset to handle audio input and output selection is a required feature for any real-time communication app. To implement audio device selection using the Android framework requires hundreds of lines of complex code. AudioSwitch was written to encapsulate the complexity of this feature and solves the following challenges:

    • Manage audio device selection
    • Detect changes in audio device availability
    • Handle audio device selection errors and timeouts
    • Provide a reliable Bluetooth selection service

    Today, we are proud to announce the General Availability of AudioSwitch!

    An Update to Deploying Video Apps video-deploying-app-update.png

    Ahoy!

    What an incredible journey it’s been since we released our Video collaboration apps earlier this year. To date, we have observed thousands of deployments, collaborated on hundreds of Github issues, and helped many developers accelerate their Programmable Video solutions to market.

    Today we are excited to announce an important update to the collaboration apps and the Twilio CLI RTC plugin intended to help developers deploy more Video!

    Passcode Update

    Deploying a Video app with version 0.1.x of the RTC plugin results in a 10 digit passcode being generated. Reference the following example output.

    $ twilio rtc:apps:video:deploy --authentication passcode --app-directory /path/to/app
    deploying app... done
    Web App URL: https://video-app-1111-dev.twil.io?passcode=1111111111
    Passcode: 1111111111
    

    Starting with 0.2.0, the RTC plugin increased the length of the passcode from 10 digits to 14. Reference the following updated output.

    $ twilio rtc:apps:video:deploy --authentication passcode --app-directory /path/to/app
    deploying app... done
    Web App URL: https://video-app-xxxx-xxxx-dev.twil.io?passcode=xxxxxxxxxxxxxx
    Passcode: xxx xxx xxxx …

    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

    Screenshot of a telemedicine app. The text says "Welcome to Owl Hospital Telemedicine" and there are 2 smiling, real live people video chatting.

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