Edit...
I changed the framerate from 2/1. Latency is now dropped to 4seconds. Are
there any other ways I can drop the latency?


>From iPhone to Pi

iPhone:
avfvideosrc device-index=1 ! *video/x-raw,framerate=2/1* ! vtenc_h264
allow-frame-reordering=false realtime=true ! rtph264pay ! gdppay !
tcpserversink host=192.168.1.211 port=5000

Pi:
gst-launch-1.0 -v tcpclientsrc host=192.168.1.211 port=5000 ! gdpdepay ! 
rtph264depay ! avdec_h264 ! videoconvert ! videoscale ! 
video/x-raw,width=1366,height=768 ! fbdevsink sync=false
