gstreamer1.0, gst-omx, gst0.10 vs gst1.0

My two pipelines comparing gstreamer-0.10 and gstreamer-1.0:
GST_DEBUG=*:6 gst-launch-0.10 -v videotestsrc num_buffers=10 ! omx_h264enc !
fakesink &> vidtest0.10.log
vs.
GST_DEBUG=*:6 gst-launch-1.0 -v videotestsrc num_buffers=10 ! omxh264enc !
fakesink &> vidtest1.0.log
I am using the same OMX library libtiomx.so in the above two cases.
The first pipeline works fine but the second pipeline I get the following
log. I don't understand the two lines with omxh264enc with fakesink. What
might be wrong with the omxh264enc element?
