can't ingest RTSP stream

Hi,

WCS doesn't want to take the RTSP stream from my HDMI H.264 encoder device. The RTSP stream plays just fine in VLC. What can I change to get this to work? All configs are default. I tried this on my Debian server, but I get the same result on AWS.

Here is the RTSP communication log from a Wireshark capture. It shows that the SETUP and PLAY steps are missing:

It seems WCS can't parse SDP

We raise ticket WCS-2780. Will check SDP parsing and report.
Please provide public RTSP URL. Then we will be able to connect to the camera and test directly.

We tried to connect to RTSP URL provided, but all connection attempts are failed with exception
Code:
08:27:07,913 WARN  annelUpstreamHandler - pool-45-thread-1 EXCEPTION, please implement com.flashphoner.rtsp.RtspResponseHandler.exceptionCaught() for proper handling.
java.io.IOException: Connection reset by peer
So please check your RTSP camera, or provide 24/7 access to the stream, or, if this is not possible for some reason, collect a report including traffic dump as described here. The traffic dump should be collected on WCS as follows:
1. Start traffic dump collection
Code:
sudo tcpdump -npi any -B 10240 -w log.pcap
2. Try to play RTSP stream, make sure the problem is reproduced
3. Stop traffic dump collection
Then send us logs ant traffic dump archive using the following link. If the archive size is greater than 20 M, place it to some cloud drive and send us the link to download.

Network issue, sorry. The test stream is now available for you.
Please try again using the same RTSP URL.

I can view the stream from an external IP using ffmpeg:

Hello,

WCS build with fix for WCS-2780 - 5.2.685. The problem with SDP parsing was due to invalid value of profile-level-id (profile-level-id=0).
