This repository is a collection of sample applications demonstrating features of the OpenTok.js (Vonage Video API) SDK. It contains 14 standalone sub-projects, each focusing on a specific capability: basic video chat, archiving, signaling, background blur, audio/video transformers, canvas publishing, device selection, stereo audio, stream filters, and end-to-end encryption. The samples are implemented in vanilla JavaScript with HTML/CSS, and a Node.js server for the encryption demo. The code is well-structured and serves as reference implementations for developers integrating Vonage video into web applications. The most technically interesting components involve media processing with Web Workers, Canvas pixel manipulation, and the Web Audio API for stereo streaming.
