Gst rtsp server : rtsp-media.c wait_preroll: failed to preroll pipeline

Hi all
I working on GStreamer 1.4.5 with gst-rtsp-server 1.4.5
two pipelines are running in my embedded board (IMX6 - ARM)

1. camera-> h264encoder->rtppayloader ->udpsink (to loop back interface, localhost)
2. gst-rtsp-server : test-launch (udpsrc ->capsfilter->rtph264depay->queue->h264parse->rtph264pay )

if i run the source (first pipeline) and gst-rtsp-server from init , the rtsp- server failed with

If i run source and server  after the boot completion, then no issue , streaming works.
I tried ifconfig up/down of loopack interface before setting the source to PLAY state.
Also tried to run the rtsp-server before running video source. Added plugin path and USER, HOME to initscript. how much i try if i run it from initscript it doesn't work .
Please help, i can't figure out anything out of this

With Regards
John
