Libargus setBayerHistogramRegion function not implemented

Robotics & Edge Computing Jetson & Embedded Systems Jetson Xavier NX
1

We’re using the Jetson Xavier NX platform with L4T 32.4.3 and using the Argus library to access the image stream from the camera.

  1. Is there a version mismatch between libargus in the documentation and what is deployed with L4T?
  2. How do we find the version of libargus that is described in the L4T documentation,
  3. How can we update the libargus library if we want to use that function, without upgrading our version of Jetpack?

Here is from r32.5(J4.5.x)

Hi Shane,

Thanks for the quick response. As I had mentioned before we are constrained on the L4T version and can’t upgrade to r32.5(J4.5.x). Is there a way to get this for L4T version 32.4.3?

Sorry, it involve many libs for the camera framework it’s could be better to upgrade to 32.5
