Wowza Streaming Engine

Hi,

We use Wowza streaming engine to connect to IP cameras via VMS such as Genetec, Milestone etc.
For some of the RTSP camera urls, we have noticed the following logs in Wowza log files

I have noticed that once the above logs are logged, the RTSP session is destroyed. However, some of these cameras when streamed in VLC using the same URL continue to stream.

Questions:

What is the meaning of these logs?

Does it mean that Wowza was not able to pull even a single packet or not enough packets to continue streaming the camera?

What would be scenarios where a RTSP streams would work smoothly in VLC but get disconnected in Wowza streaming engine.

Please let us know if we need to add some properties etc to troubleshoot the issue.

Wowza version: 4.8.20
