Gstreamer in weston/wayland

Hi

I am trying t build a player in R car-E2 (arm based board).I already build weston
/wayland ,gststreamer-1.0 and waylandsink in R car-E2. I checked all the plugins using gst-inspect-1.0.Then i started to test video rendering as " gst-launch-1.0 videotestsrc ! waylandsink.I got plenty of errors like
ERROR:from element /Gstpipeline:pipeline0/GstvVideoTestSrc:videotestsrc0: Internal data flow error
Additional debug info:
gstreamer-1.4.1/libs/gst/base/gstbasesrc.c(2933):gst_base_src_loop():/GstVideoTestSrc:videotestsrc0:
streaming task paused, reason not negotiated (-4)
ERROR:pipeline doesn’t want to preroll."
.Can anyone help me to solve this problem.I debugged with GST_DEBUG=4 gst-launch-1.0 videotestsrc ! waylandsink.

regards
Abin
