Case Replay and Comparison for RTSP Inspector: Setup and Workflow Guide
Save a diagnostic case
After analyzing a stream, save the session as a .risession file. The file preserves:
- Complete RTSP control exchange (DESCRIBE, SETUP, PLAY, TEARDOWN)
- SDP from the DESCRIBE response
- RTP packet samples with decode
- RTCP sender/receiver reports
- Timeline and cockpit diagnostic state
Replay offline
Open a saved .risession file to review the evidence without reconnecting to the camera. All diagnostic views are available exactly as they were during the live capture.
Compare working vs failing
The most powerful diagnostic pattern in RTSP troubleshooting:
- Capture a session from a camera that works correctly
- Capture a session from the failing camera
- Compare side by side
Look for differences in:
- DESCRIBE responses (SDP structure, codec listings, payload type assignments)
- SETUP negotiation (transport mode, client ports)
- RTP payload (sequence numbers, timestamps, payload type bytes)
- RTCP reports (loss counts, jitter, interarrival metrics)
The difference between working and failing is usually the root cause.
