Unable to stream RTSP using Live555 proxy server

Question

I am using Live555 streaming media for an application which records and re-streams RTSP streams coming from IP camera. For that, I am using openRTSP for recording and live555 proxy server for re-streaming the camera stream. For a few of the cameras we are facing a strange issue where in the camera recording happens successfully, however the live555 proxy server is unable to generate a new stream for the same camera stream (there is no indication of failure in the verbose output dump, however the rtsp url generated by proxy server cannot be decoded by an rtsp client). Since I do not have any idea about the live555 proxy server details, I have been unable to get into this problem. I tried streaming the same camera stream using VLC and that works fine. What could be possibly wrong with this. I am hereby attaching the verbose output for reference.

Awaiting your response.

Answer 1

It could be mostly because of udp ports blocked because of firewalls. Try -t flag to force the transmission through tcp.
