I just wanted to point out some hiccups that caused me some head-scratching when using this tutorial to setup a stereo pair of zed x one cameras.
Namely, if you do as the tutorial suggests and first form the virtual camera and allow it to stream, you have to kill the zed media server daemon service in order for the zed x one calibration tool to see the individual cameras.
Additionally, if you have already formed a virtual camera but chosen the left/right ordering of the cameras poorly (i.e. such that the zed x one calibration tool thinks they are reversed), then you have to swap the camera cables (requiring a reboot) and swap the cameras in the virtual configuration.
Maybe I missed some information somewhere, but if not, then hopefully this saves others some headache.
