[Live-devel] SET_PARAMETER doesn't get handled in the RTSPServer over TCP

[Jer Morrill]

Thanks for the quick response!

I have attached a client debug output and server debug output text files (hope that's ok for this list).  These are from the same rtsp session.

Though the log does say RTSPServer::RTSPClientSession::handleRequestBytes(...) does say "parseRTSPRequestString() succeed...", it does not pass the next check:

if (ptr + newBytesRead < tmpPtr + 2 + contentLength) break; // we still need more data; subsequent reads will give it to us

At the point of the content length check the buffer looks like this:

SET_PARAMETER rtsp://127.0.0.1/media?dev=1&source=archive&startTime=129661319116046065/ RTSP/1.0
CSeq: 6
User-Agent: HJT RTSP Client (LIVE555 Streaming Media v2011.12.02)
Session: CA195293
Content-Length: 30

The complete command should also have (\r's and \n's excluded):
GotoTime: 1234567890

It does get these "GotoTime..." bytes afterwards the next calls to "handleRequestBytes", but the server never successfully parses the SET_PARAMETER command in RTP over TCP.  Totally weird other messages get through just fine.

Thanks again for all your help!  Hope this is reproducible for you as I hate to send anyone on a wild goose chase!

I am running the 12-2-2011 build of Live555.  When I run RTSPClient::sendSetParameter(...) with a session that is running UDP to a live555 server implementation, the server parses and successfully runs the RTSPClientSession:: handleCmd_SET_PARAMETER (overridden in a subclass).  If I run RTSPClient:sendSetParameter(...) with a session that is running via TCP, it does not ever get to the RTSPClientSession::handleCmd_SET_PARAMETER.  Seems sending trickplay commands work fine in both TCP and UDP.

That's strange.  (It's especially strange that other commands - e.g., "PLAY" - work OK for you in RTP-over-TCP mode, but that "SET_PARAMETER" does not.)


I can provide more debug details if needed

Yes, please add
#define DEBUG 1
to the start of "liveMedia/RTSPServer.cpp", recompile and rerun your server, and access it both with a RTP-over-UDP client, and with a RTP-over-TCP client.  Please send us the debugging output in each case.
