I'm using mediasoup in an Express project to build a video conferencing application. However, I'm facing an intermittent issue where a peer joins the room but cannot see/hear others (video/audio streams from other peers are not displayed). The issue is resolved when the peer refreshes the page.

Here are the details of my problem:

Problem Description:

When a peer joins the room, they do not receive video/audio streams from other peers. The names of other peers are visible, but the streams are missing (displayed as "black squares"). The issue is resolved when the peer refreshes the page.

Context

• mediasoup version: v3
• Environment: Node.js with Express
• Browser: Chrome (latest version)
• mediasoup configuration: I'm using a standard configuration for WebRTC transports and routers.

Hypotheses

Based on the logs, I suspect the issue might be related to:

• SSRC desynchronization: RTP packets are not correctly associated with streams.
• DTLS/SCTP connection issues: The DTLS or SCTP connection is not established properly.
• Bandwidth instability: Bandwidth fluctuations might be causing interruptions.
• ICE connection issues: The ICE connection is timing out or failing.
• Consumers problems

Question

• Do you have any ideas about what could be causing this issue?
• How can I better diagnose and resolve this problem?
• Are there any best practices for handling SSRC, DTLS/SCTP connections, or bandwidth issues in mediasoup?

Thank you in advance for your help!
