Hi,
Please find attached output generated by tcpdump from rtsp sessions
between an Axis IP camera and a host running VLC and openRTSP (obviously
not simultaneously).
Does this help finding out why live555 generates the "StreamClose"
message only while running VLC, and not while running openRTSP?
cheers, Erik

Hi,
I could agree to that if this would happen everytime running openRTSP,
like it does happen everytime running VLC. But this shutdown by the Axis
camera happened only during the first openRTSP session, and normally in
VLC it took longer than 5 seconds until VLC showed the "StreamClose"
message.
After this first openRTSP session, I tried maybe up to 10 to 15 times to
reproduce the problem in openRTSP, but the problem did not appear again.
So my conclusion is that VLC shows different behavior than openRTSP
during an rtsp session with my Axis camera.
cheers, Erik

Very interesting:
only during the first run of openRTSP streaming was aborted
spontaneously after a very few seconds. See openRTSP.log.1 attached.
This the key part:
Started playing session
Receiving streamed data (signal with "kill -HUP 45822" or "kill -USR1
45822" to terminate)...
Received RTCP "BYE" on "audio/MPEG4-GENERIC" subsession (after 5
seconds)
Your server (the Axis camera) is signalling - after just 5 seconds of
streaming - that the stream has shut down. The client ("openRTSP" in
this case, but also VLC) is then - quite properly - honoring the
server's request, by shutting down the RTSP connection.
So, you need to figure out why your server is signalling shutdown
after just 5 seconds.
