I am not trying play while i am recording from the stream.

I am trying to record for some time and pressing control+c which forcing EOS and mp4 file has been created.  then i am trying play that mp4 file using media player available with ubuntu 12.04.

Please help me to know what i am doing wrong in the below pipeline while i am trying to record a stream into mp4 format  for a duration by pressing cntr+c which forces EOS to the mp4 file. The problem that i am facing ; the seek is not working and playing too fast when i am trying to play that recorded mp4 file. here is the pipeline -- 

gst-launch-0.10 -e udpsrc port=1234 ! "application/x-rtp,payload=127" ! rtph264depay ! filesink location=x001.mp4
