[Live-devel] RTP over TCP - What happens if a client closes the RTP socket gracelessly?

[Renato MAURO (Libero)]

Hello Ross.


    If an RTSP client (not developed by me and sadly not based on Live555) asks for a video, streaming with RTP over TCP, and after some minutes closes the RTP socket gracelessly (bug or black-out), doesn't (or can't) send the RTSP Teardown command, then the Live555 RTSP Server (OnDemandServerMediaSubSession):

1) waits only for the usual liveness timeout due to the lack of arrival of the RTCP RR command and, in case, terminates the matching RTPClientSession;

2) manages the usual liveness timeout; but it terminates the matching RTPClientSession also if the select() function, before the usual liveness timeout has occured, understands that the other end-point is dead (since the TCP level acknowledge is not received even after some retransmissions).


Thank you very much,

    Renato MAURO
