09/24/2025, 4:16 AMI'm glad you're looking into maintaining steady participant composite egress during reconnects and managing errors effectively. Here are some helpful tips to guide you through:
• Handling Reconnects: LiveKit thoughtfully uses ICE restarts and resume logic to help minimize disruptions when network hiccups happen. If resumption doesn’t work, a full reconnect kicks in, and the participant's tracks get republished automatically—so you don’t have to worry about manual intervention.
• Egress Resilience: The participant composite egress is designed to stay active even if participants disconnect briefly. This way, your recordings or streams won’t stop unexpectedly, giving you peace of mind.
• Error Management: The egress system leverages GStreamer to handle errors robustly. For instance, if there’s a transient RTMP connection failure, it’s managed smoothly without crashing your entire pipeline.
• Dynamic Stream Updates: You can update RTMP stream URLs on the fly during active egress to swap out any failed endpoints without needing to stop the recording—pretty handy, right?
• Monitoring: To keep everything running smoothly, you can use webhooks and API polling to monitor egress status and catch any issues early.
These features work together to keep your egress steady and errors handled gracefully. If you'd like, I’m here to help with any details or assist you through the implementation process—just let me know!

09/24/2025, 4:16 AMTo help make sure your composite egress keeps going smoothly when a participant reconnects, LiveKit offers several handy features:
• Connection Resilience: LiveKit tries to pick up right where it left off during brief network hiccups by reconnecting the signaling WebSocket and starting an ICE restart. This way, your egress session stays uninterrupted since the participant’s identity and published tracks stay the same.
• Egress Continuity: Composite egress is built to stay active even if participants disconnect for a little while. For instance, tests show that egress remains active when the publisher leaves and then rejoins the room.
• Automatic Track Republishing: When a participant fully reconnects, their local client automatically republishes all tracks once signaling is back, so the egress can continue seamlessly without you needing to do anything extra.
These thoughtful features are all about making sure short disconnections don’t interrupt your composite egress experience. If you have any questions or want to talk through a particular situation, I’m here to help—just let me know!
