Isaac ROS 4.6 removes `isaac_ros_argus_camera` with no migration path for CSI cameras -- Issue with Orin + Jetpack 7.2

[SamuelFoo]

Summary

ros-jazzy-isaac-ros-argus-camera is absent from Isaac ROS 4.6 apt repositories. For users on Jetson Orin with a plain CSI camera this removes the only Isaac ROS camera driver with no replacement.

Quick Links

SIPL currently doesn't support MIPI/CSI (but it's planned to):

isaac_ros_argus_camera is not supported on Isaac ROS 4.x:

Environment

• Jetson Orin, JetPack 7.2 / Jetson Linux r39.2
• Isaac ROS 4.5 → 4.6 base image (nvcr.io/nvidia/isaac/ros:isaac_ros_*-arm64-jetpack)
• Plain CSI (MIPI) camera, not GMSL, not CoE

Possible Workarounds

• Use Isaac ROS 4.5 on Jetpack 7.2, add TRT override (required, see: Isaac ROS 4.5 pins TensorRT 10.13.3, which has no sm_87 cubin — TensorRT inference is broken on Jetson Orin / JetPack 7.2 NVIDIA-ISAAC-ROS/isaac-ros-cli#22)
• Write our own ROS adapter, no zero-copy, no isaac_ros_argus_camera, using gscam and nvarguscamerasrc
• Use Isaac ROS 4.6, build isaac_ros_argus_camera from source, and pray it works. This probably won't work since GXF was sunsetted.
• Buy this adapter: https://www.arducam.com/arducam-gmsl2-8mp-camera-extension-kit-for-nvidia-jetson-orin-nano-orin-nx.html
