Argus set contrast

nvcamerasrc has an easy “contrast” setting that doesn’t seem to be represented in Argus. How should I go about setting the contrast?

Looks like there’s no this API for the argus. You can find all of argus API from the l4t-document.

How does nvcamerasrc do it? I assumed that was built with Argus.

Check this from the l4t-document. The they are different API.
