I see that you've already got mpeg4videoparse in your pipeline.  Sounds
like all you need to do is somehow tell it that you're giving it full
frames.

Hi All,
We are using
gst-plugins-bad-0.10.13,gst-plugins-base-0.10.23,gst-plugins-good-0.10.1
4.
we are using pipeline below mentioned

gst-launch rtspsrc location=rtsp://192.168.1.223/mpeg4 latency=100
name=demux demux. ! queue ! rtpmp4vdepay ! mpeg4videoparse !
dmaidec_mpeg4 ! TIDmaiVideoSink videoOutput=LCD videoStd=320X240
demux. ! queue ! rtppcmudepay ! mulawdec ! alsasink


  gst-launch application takes 3-4 second for displaying video on Output
device(LCD).
Please suggest me is their any way to optimize the execution time.


The version at HEAD should contain a few optimisations good to reduce
the set-up latencies. Unfortunately, I don't think your system will ever
be able to get anything better than 2 seconds, mainly because of this:

I would suggest you to try with gst-dsp.
