I tested the capture to display latency on Jetson nano with imx219, with below command
gst-launch-1.0 nvarguscamerasrc maxperf=true ! 'video/x-raw(memory:NVMM),width=1280, height=720, framerate=30/1, format=NV12' ! nvvidconv flip-method=0 ! 'video/x-raw,width=960, height=616' ! nvvidconv ! nvegltransform ! nveglglessink -e
The latency is reaching around 130ms~180ms, considering our application scenario, is there any option/possibility to reduce the latency?
