Simple RTSP server

Hello, we have created a simple RTSP server through Gstreamer to transport video from our new device into VMS systems. We have tried to stream this through the Universal Channel 01 with no luck.

Currently it works in VLC.

The RTSP server does not require authentication, please advise what I can do to dig deeper into it to figure out why it is not working.

This knowledge base article might be a help..

It didn’t help, VLC works fine. I am sure it must be one of my settings I set incorrect?
