How to run near-real time object detection from a quadcopter using NVIDIA Jetson Nano to FPV googles/screen

I want to use an NVIDIA Jetson to do on-board object detection from a quadcopter. However I do not know how to push the video feed from the drone gimbal into the NVIDIA Jetson, and how to push the drone footage with object detection results down the the ground control station/FPV goggles. Has anyone done this before? If so what kind of code do I need to run on the NVIDIA Jetson? Thanks!!
