Jetson Nano 2GB/4GB (issue: zed2i writing video frames dropped)

Hi,
There should be no existing implementation and you would need to refer to the samples in

/usr/src/jetson_multimedia_api

And develop your use-case. For USB cameras, may refer to the steps in Jetson Nano FAQ

Q: I have a USB camera. How can I launch it on Jetson Nano?

To capture frame data through v4l2.
