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?

Hi @sdk17586

How is your test linked to this question? I’m sorry, but I can’t figure out the connection.

However, it will be possible to connect 4 ZED X cameras to the same GMSL2 capture card when we release the new capture card model (end of 2023, early 2024). The current model can handle a maximum of 2 ZED X cameras simultaneously
