How to change setting value like exposure when using ROS to get image data of IMX390 gmsl Leopard imaging camera?

Hi,

We are using ROS to record the image data of Leopard imaging gmsl camera. But when in the night the images are too bright. So we want to modify some parameter to improve it. Could you tell me how to do before start ROS launch file? Thanks!

If you are using nvarguscamerasrc you can check with gst-inspect-1.0 nvarguscamerasrc to get what you can set.
