Troubleshooting

Common failure classes:

• Authentication rejected: verify credentials and camera auth mode.
• DESCRIBE is not SDP: check camera endpoint path.
• SETUP rejected: confirm the camera supports the requested transport mode.
• PLAY succeeds but no RTP arrives: inspect firewall, client port reachability, and UDP/TCP transport settings.
• H264/H265 is not decodable: inspect parameter sets, IDR/CRA evidence, and FU/AP fragment warnings.

When in doubt, save a .risession case and compare it against a known-good baseline.
