The release notes of JetPack 4.5 mention that " V4L2 API is extended to support interacting with CSI Camera. Implementation is compliant with V4L2 spec.".
I expected the cameras to be now fully accessible via v4l2 but this does not seem to be the case: Querying the /dev/video device still yields the same video formats and controls as with older JetPack versions. How does accessing the ISP functions via v4l2 work with JetPack 4.5?
