Need urgent help with clockoverlay

[rbattu]

Hi All, 

I was trying to clockoverlay , but not succesful, below is the command and
the resulted caps. The output showing was struck after the timeoverlay, any
guess why the flow isnt going through clockoverlay? 

gst-launch-0.10 -v  tcpclientsrc host=192.168.0.102 port=5000 ! gdpdepay !
rtph264depay ! ffdec_h264 ! ffmpegcolorspace !
video/x-raw-yuv,format=\(fourcc\)YUY2 ! autoconvert !    timeoverlay
halign=right valign=top ! clockoverlay halign=left valign=top
time-format="%Y/%m/%d %H:%M:%S" ! xvimagesink sync=false

Output:

However, when I changed the debug level to 3, I  see the following warning
in a loop:
0:00:06.846734151 11792  0x86264f0 WARN        videosegmentclip
gstvideosegmentclip.c:129:gst_video_segment_clip_clip_buffer:<videosegmentclip0>
Buffer without valid timestamp


Also on a side note I tried with videotestsrc as below, and it is
successful:
gst-launch-0.10 -v videotestsrc ! video/x-raw-yuv,format=\(fourcc\)YUY2 !
ffmpegcolorspace !    timeoverlay halign=right valign=top ! clockoverlay
halign=left valign=top time-format="%Y/%m/%d %H:%M:%S" ! xvimagesink

Please help. Thanks.
