[Live-devel] not able to respond to SET_PARAMETER

[venugopalpaikr]

Hi,
    I am modifying Live555 to respond to Windows Media Player. While trying
to establish the session WMP sends SET_PARAMETER. The actual response to
SET_PARAMETER should be

RTSP/1.0 200 OK
Content-Type: application/x-rtsp-udp-packetpair;charset=UTF-8
Content-Length: 43
Date: Mon, 01 Dec 2008 05:28:27 GMT
CSeq: 3
Session: 13114845032829158031;timeout=60
Server: WMServer/9.5.6001.18000

type: high-entropy-packetpair variable-size*

The end of message should be at d asterisk sign as shown above.

I have written the response for SET_PARAMETER as shown :

void RTSPServer::RTSPClientSession::Call_SET_PARAMETER(char const* cseq) {

unsigned char ResponseBuffer[10000];

snprintf((char*)ResponseBuffer,sizeof ResponseBuffer,"RTSP/1.0 200
OK\r\nContent-Type:
application/x-rtsp-udp-packetpair;charset=UTF-8\r\n%sCSeq: %s\r\nSession:
%d;timeout=60\r\nServer: WMServer/9.5.6001.18000\r\n\r\n",dateHeader(),cseq,
fOurSessionId);

memset(fResponseBuffer,0,RTSP_BUFFER_SIZE);

send(fClientSocket,(char const*)ResponseBuffer,
strlen((char*)ResponseBuffer), 0);

snprintf((char*)ResponseBuffer,sizeof ResponseBuffer,"type:
high-entropy-packetpair variable-size\r\n");

send(fClientSocket, (char const*)ResponseBuffer,
strlen((char*)ResponseBuffer), 0);

memset(fResponseBuffer,0,RTSP_BUFFER_SIZE);
}

the response is as shown below
RTSP/1.0 200 OK
Content-Type: application/x-rtsp-udp-packetpair;charset=UTF-8
Date: Fri, Jan 02 1970 22:53:22 GMT
CSeq: 3
Session: 1;timeout=60
Server: WMServer/9.5.6001.18000

type: high-entropy-packetpair variable-size

the message ends at the asterisk sign which i don't want. Am not able to
replicate the response properly. How should i modify the code? if i don't
use "\r\n\r\n" the response gets appended to the Teardown response and is
sent along with it when a Teardown request is received.

REGARDS,
Venu
