Attached is the command line log as you requested.

The client sends two Describes on the same rtsp connection:
DESCRIBE rtsp://192.168.50.123:554/mpeg4/1/media.amp/trackID=1 RTSP/1.0
CSeq: 1
Authorization: Basic c2lnaHRsb2dpeDpwdXNoMmVkZw==

DESCRIBE rtsp://192.168.50.123:554/mpeg4/2/media.amp/trackID=1 RTSP/1.0
CSeq: 2
Authorization: Basic c2lnaHRsb2dpeDpwdXNoMmVkZw==

The Response is:
RTSP/1.0 200 OK
CSeq: 1
Date: Mon, Sep 17 2007 18:58:20 GMT
Content-Base: rtsp://192.168.50.123/mpeg4/1/media.amp/
Content-Type: application/sdp
Content-Length: 532

a=control:track1

And the client sends:
SETUP rtsp://192.168.50.123:554/mpeg4/1/media.amp/trackID=1 RTSP/1.0
CSeq: 3
Transport: RTP/AVP;unicast;client_port=15020-15021

The log shows that the second describe causes parseRTSPRequestString()to be
called with a pointer to the first DESCRIBE.

Thanks for looking at this,
Geoff
