Ask for samples of L4T Multimedia API Reference index

How to use the functions which list in “files” of L4T Multimedia API Reference?

https://docs.nvidia.com/jetson/l4t-multimedia/files.html

I want to do some control to my CSI MIPI camera(IMX 219) on Jetson Nano, like “ae”, “awb”, “color matrix correction”, “denoise” and so on. And I found that some functions in L4T Multimeida fitted my request,but I have no idea to start the next step on how to use them, because I could not find any samples or guidance about that.

Could you please show me some samples about that? Urgently. Pleas give me some guidance. Thank you so much!
