Any idea why this pipeline has about a 2 sec delay?

Hi,

I'm running this pipeline on a TX2. The elements are supposed to be using
hardware decoding and encoding. Somewhere there is a huge latency, but im
not sure how to profile this on a TX2. GSTShark isnt running on my TX2 to
get any latency or timing info. Any idea where the issue might be or how I
can reduce the latency?

Input over udp is h264 in an mpeg-ts. 
gst-launch-1.0 udpsrc port=6110 ! tsdemux ! queue ! h264parse ! omxh264dec !
nvvidconv ! 'video/x-raw(memory:NVMM),format=I420,width=720,height=480' !
omxh264enc control-rate=2 preset-level=0 bitrate=3000000 ! mpegtsmux !
udpsink host=192.168.0.001 port=4100

Thanks,

Bogdan
