Build a Watch Party Sync Demo with Shaka Player and PubNub

PubNub's tutorial outlines the integration of real-time synchronization in watch parties using the Shaka Player and PubNub's messaging platform. The guide emphasizes that video streaming is not handled by PubNub; instead, it focuses on synchronizing playback actions such as play, pause, and seek across multiple viewers using lightweight messages. This setup allows for a scalable and low-latency experience where one person acts as the host, controlling the playback for all followers, who automatically sync with the host's actions. The tutorial includes a demo, requires minimal setup with JavaScript and a basic web app, and highlights features like real-time event subscription for enhanced user interaction and debugging capabilities. It also discusses the potential for adding social features such as chat and emoji reactions to enrich the watch party experience, demonstrating the flexibility and effectiveness of using PubNub for real-time synchronization without the need for complex server setups.
