Preliminary Checks

Description

While trying to determine how many cameras were detected using the 'v4l2-ctl --list-devices' command, I encountered a bug. I have connected two ZED-X and two ZED-XM cameras.

trdv@ubuntu:~$ v4l2-ctl --list-devices NVIDIA Tegra Video Input Device (platform:tegra-camrtc-ca): /dev/media0

vi-output, zedx 30-0010 (platform:tegra-capture-vi:0): /dev/video0

This is the result that appeared.

However, when two were connected, this is the result that appeared.

NVIDIA Tegra Video Input Device (platform:tegra-camrtc-ca): /dev/media0

vi-output, zedx 30-0018 (platform:tegra-capture-vi:0): /dev/video0 /dev/video1

vi-output, zedx 31-0018 (platform:tegra-capture-vi:1): /dev/video2 /dev/video3

This is the result that appeared. Is it not possible to connect up to four ZED-X cameras to the Jetson?

I created the following launch file in the zed_wrapper package to simultaneously operate ZED-X and ZED-XM cameras.

Steps to Reproduce

  1. v4l2-ctl --list-devices
  2. ...

Expected Result

error

Actual Result

error

ZED Camera model

ZED2

Environment

ubunto 18.04

Anything else?
