[Live-devel] unexpected "StreamClose" in VLC under FreeBSD

[Erik van Dort]

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
