Hi,

Thank you for the reply. I am working on enabling gstreamer1.0 in the
hardware.

I would like to bring to your notice that I observed crash few times when I
run the same command ["gst-launch-0.10 rtspsrc location=XYZ
drop-on-latency=true latency=0 ! rtph264depay ! filesink location=XYZ " ]. 
Few times it throws
error[/GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0/GstUDPSrc:udpsrc0: Could
not read from resource. ] and few times its crashing.

Crash logs

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
