Welcome to the Youtube-Sync Wiki!

About the Project

Youtube-Sync is a project that aims to sync up video streams to allow students at the University of Illinois to view prerecorded lectures together in real time. This project uses the Video.js API.

As of now, the video player can support up to 4 people watching at the same time. Any user can pause/play the video or skip ahead/behind and these changes will be synchronized between all users.

Future features include websockets functionality to reduce server load and a built-in chat.
