rtspsrc with ip camera LTV

[KnightUS]

i start testing new version of ltv cams. for test i use simple gst-play
(1.9.2).
gst-play rtsp://admin:123456@192.168.37.245:554/profile1/ working fine, but
if i start second stream (again start gst-play and have 2 connections) i get
error : Error (400): Bad Request

i try to start gst-launch with debug=true
gst-launch-1.0 rtspsrc
location="rtsp://admin:123456@192.168.37.245:554/profile1/" debug=true
