The TCP stream from the satip server is broken.

Updated by Hi,
is this related to the RTSP message (RTP data) being too long, and the data being corrupted ?
If yes, is it possible to have this as a warning and not close the connection ?
Thanks
Updated by Jaroslav Kysela over 7 years ago
The problem is that the embedded RTSP data are corrupted (the size in the '$' header does not match the received data), so the RTSP session is no longer valid, because tvh (client) cannot parse next RTSP answer.
Updated by Jaroslav Kysela over 7 years ago
The best debugging technique is to capture the whole RTSP TCP stream (using wireshark or tcpdump) and look where the issue is.

I have encountered this issue again, added the following patch for better debugging:

so maybe the problem still there... will have time to check it better this afternoon.
Jaroslav if you need i can give you access to the system...maybe it's easy for you to debug!
Thanks
