Dear Ross,<br>
<br>
My client use VLC as rtsp server, and i use live555 proxyserver(last version 2015.07.19) to proxy the rtsp stream. From the log generated by live555 proxyserver, every about 60s (default timeout), VLC will send a "BYE" signal to live555 proxyserver, this will
cause the rtsp proxy process broken and a restart of session.<br>
<br>
Following i attach generated by live555 proxyserver:<br>
<br>
<i><span style="font-size:10.0pt">Server: VLC/2.0.3<br>
Content-Length: 0<br>
Cseq: 7<br>
Public: DESCRIBE,SETUP,TEARDOWN,PLAY,PAUSE,GET_PARAMETER<br>
ProxyServerMediaSubsession["H264"]: received RTCP "BYE". (The back-end stream has ended.)<br>
ProxyServerMediaSubsession["H264"]::closeStreamSource()<br>
ProxyServerMediaSubsession["H264"]::closeStreamSource()<br>
ProxyServerMediaSubsession["MPA"]::closeStreamSource()<br>
ProxyServerMediaSubsession["H264"]::~ProxyServerMediaSubsession()<br>
ProxyServerMediaSubsession["MPA"]::~ProxyServerMediaSubsession()</span></i><br>
<br>
I searched on web and i found a possible bug on vlc that only support RTSP messages (like GET_PARAMETER) as RTSP keepalive and not RR packets.<br>
However I can't change back-end camera software(vlc/2.0.3) so if possible how can I change the code of ProxyServerMedia to avoid this error?
