How to set compressedDepth image_transport params at launch

I want to use the compressedDepth image_transport with the RVL algorithm. The default algorithm is "PNG" but I'd like to change that. I'm on melodic with the image_transport_plugins noetic-devel branch. I've successfully compiled it on both my desktop and my jetson nano and used rqt to reconfigure the compressedDepth image_transport. My setup is functional once I manually configure the params.

How can I set the params when I launch a camera capture node?

Just to clarify. Are you running melodic in your desktop and noetic in Jetson Nano?

When you say your setup is functional can you show the params? And are you looking to create a launch file?

Here is a link of different launch file examples using depth camera:

I'm running melodic on both my desktop and the Jetson Nano. I compiled from source the image_transport_plugins package using the noetic-devel branch. I'm well aware of the launch files provided with the realsense-ros package. I've tried adding a <rosparam> line at the end of the launch file but it's not registered by the Parameter Server.

@Alex-SSoM you will need to share more details, for example show your launch file, it's hard to help without seeing what you have done or haven't.

Since I didn't need compatibility with PNG compression, I compiled the image_transport_plugins from source with RVL as the default algorithm.
