5.Media Servers: Janus/WebRTC
6.Deployment: AWS with Auto Scaling, Dockerized services
Feature Development
Video Conferencing with Real-time Communication
The WebRTC protocol was used to handle real-time video, audio, and screen-sharing. Socket.IO was implemented to facilitate signaling between users during the peer-to-peer connection establishment.
Breakout Rooms
Use Case: Users can split into smaller groups within a meeting.
Implementation:Used Socket.IO rooms to handle dynamic breakout room creation and management.Integrated room-specific messaging and audio/video streams.
Admin controls for moving participants between rooms.
Participant Roles
Use Case: Different roles (Host, Co-host, Attendee) with role-based access control.
Implementation:
Role assignment upon meeting creation and join requests.
Host/co-host permissions for muting participants, removing users, and starting/ending breakout rooms.
Attendee restrictions to ensure smooth moderation.
Real-time Analytics
Use Case: Provide insights like participant engagement, total meeting time, and chat/message count.
Implementation:
Tracked user actions (e.g., joining, leaving, speaking, messaging).
Stored data in MongoDB for report generation.
Created a RESTful API for accessing analytics.
Challenges and Solutions
Managing High Concurrent Users
Implementing Breakout Rooms Dynamically
Solution: Implemented dynamic room creation and destruction in Socket.IO. Maintained state consistency by syncing room data with MongoDB.
Ensuring Security
