[Live-devel] rtsp response problem

[Vincent Chen]

Hi,

I am developing a RTSP Client, and have problem sending SETUP or PLAY
command to server with RTSPClient::setupMediaSubsession() and
RTSPClient::playMediaSubsession().

If I get the SDP from server as the following message:
------------------------------------------------------------------------------------------------------------------------------------------
Sending request: DESCRIBE rtsp://172.16.2.209:554/v1 RTSP/1.0
CSeq: 1
Accept: application/sdp
User-Agent: TestClient (LIVE555 Streaming Media v2009.07.09)

Received DESCRIBE response: RTSP/1.0 200 OK
CSeq: 1
Server: VStream Streaming Server V1.0
Content-Base: rtsp://172.16.2.209:554/v1/

Need to read 355 extra bytes

------------------------------------------------------------------------------------------------------------------------------------------

I will only SETUP and PLAY H.264 video stream as the following command:
------------------------------------------------------------------------------------------------------------------------------------------
Sending request: SETUP rtsp://172.16.2.209:554/v1/trackID=0 RTSP/1.0

RTP-Info: url=rtsp://172.16.2.209:554/v1//trackID=0;seq=41204;rtptime=0
------------------------------------------------------------------------------------------------------------------------------------------

After a while, when the VIDEO stream is still playing, I wanna SETUP another
stream in the *same* RTSP connection, according to SDP, it's trackID=1.
I use RTSPClient::setupMediaSubsession()  to send SETUP.
------------------------------------------------------------------------------------------------------------------------------------------
Sending request: SETUP rtsp://172.16.2.209:554/v1/trackID=1 RTSP/1.0

Tasot T/V;ncs;oepa;letpr=27-277;server_pot5985919

------------------------------------------------------------------------------------------------------------------------------------------
you can see the Response from server is a mess, but I can be sure of one
thing, the Server do response properly to client
Because I capture the TCP/IP packet via software Wireshark. but livemedia
seems to be failed in reading and parsing response?

ps. livemedia version: 2009.07.09

thanks for reading and help!
regards,
Vincent
