Hi,
There are runtime commands you can use to control the pipeline:
Runtime commands:
h: Print this help
q: Quit
p: Pause
r: Resume
You may consider to use window-based nveglglessink, though we suggest use nvoverlaysink on Jetson Nano.

nveglglesink takes certain GPU loading and shall run better on TX2 or Xavier.
