Hou to make camera AF(auto-focus) in Jetson Nx platform?

I want to make my camera AF in Jetson NX,Is there a way to determine video sharpness with gstreamer? Or it‘s suppored in Nvidia Jetson ISP model?

Sorry, current not support AF.

Hello, I can get frame‘s definition now. Do you have an algorithm to control the motor by definition change.

Try the Get/SetFocusPositon() for manually control the focus.


Can it be set in the GStreamer program?

Sorry, didn’t implement on GStreamer program. However you can build the download the source to implement and build the /usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgstnvarguscamerasrc.so(nvarguscamerasrc) for it.
