IBM Developer Advocate Jeff Sloyer shared how a cancer clinic in Texas eliminated patients' commute by using video chat with IBM Bluemix, Twilio Video, and WebRTC. With just 26 lines of code, developers can set up a video call through their web browser using WebRTC's simple and reusable APIs, abstracting away complex low-level tech. This allows for easy embedding of communications into apps, making video conferencing a breeze, but still requires handling events like invite acceptance and participant connections, which can be simplified with just a few lines of code.
