Help on execution speed and optimization in gst-launch.

arasu
Hi All,
We are using gst-plugins-bad-0.10.13,gst-plugins-base-0.10.23,gst-plugins-good-0.10.14.
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.


Regards,
Arasu.M

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.

Gruenke, Matt

From the link:

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.
