RTSP proxy fails to connfig - DESCRIBE invalid request / empty header value

[jamesbraid]

Hey, I'm getting two different error when I test with two different IP cameras.

The first camera (test1) is an Amcrest unit, the second (test2) is a no-name IP camera. Both camera paths work fine in ffmpeg and VLC for playback. It seems like the rtsp-simple-server is making some requests that these units don't support and failing hard instead of continuing?

Let me know if I can provide any more debug info, is there a more verbose logging mode or anything?

Output from console:

Hello, thanks for reporting the bug. Communication issues between the server and cameras are unfortunately common since there are myriad of RTCP implementations, especially in embedded systems.
To fix this, i need a network dump of the data exchanged between the server and the target, that can be generated in this way:

1. Download wireshark (https://www.wireshark.org/)
2. Start capturing on the interface used for exchanging RTSP (the one of your network card)
3. Start the server and replicate the issue
4. Stop capturing, save the result in .pcap format
5. Attach

Furthermore, i'm noticing that you didn't provide a path in the second camera url:

rtsp://user:pass@camera2:554

are you sure this is the right url?

without further data i can't work on this, sorry
