Hi Ross,
we have an issue regarding a RTSP server behind a router.
The client is able to access the streaming but it displays the first
frame
after more than 12 seconds from the start time,
then usually playback stops after about 40 seconds.
If we access the streaming using testRTSPClient, no video/audio packet
is logged.
We found a work around for the issue by removing
'destination=%s;source=%s;' from SETUP command response for
UDP RTP in the file RTSPServer.cpp at line 1731 as follows:
snprintf((char*)ourClientConnection->fResponseBuffer, sizeof
ourClientConnection->fResponseBuffer,
"RTSP/1.0 200 OK\r\n"
"CSeq: %s\r\n"
"%s"
"Transport:
RTP/AVP;unicast;destination=%s;source=%s;client_port=%d-%d;server_port=%
d-%d\r\n"
"Session: %08X%s\r\n\r\n",
ourClientConnection->fCurrentCSeq,
dateHeader(),
destAddrStr.val(), sourceAddrStr.val(),
ntohs(clientRTPPort.num()), ntohs(clientRTCPPort.num()),
ntohs(serverRTPPort.num()), ntohs(serverRTCPPort.num()),
fOurSessionId, timeoutParameterString);
becames
snprintf((char*)ourClientConnection->fResponseBuffer, sizeof
ourClientConnection->fResponseBuffer,
"RTSP/1.0 200 OK\r\n"
"CSeq: %s\r\n"
"%s"
"Transport:
RTP/AVP;unicast;client_port=%d-%d;server_port=%d-%d\r\n"
"Session: %08X%s\r\n\r\n",
ourClientConnection->fCurrentCSeq,
dateHeader(),
ntohs(clientRTPPort.num()),
ntohs(clientRTCPPort.num()), ntohs(serverRTPPort.num()),
ntohs(serverRTCPPort.num()),
fOurSessionId, timeoutParameterString);
With the modified version of the streaming server, the client displays
the first frame
in 2 sec, the playback never stops and also testRTSPClient shows
video/audio packet.
Do you have any idea about this behavior?
Thanks for your help
