That's the built in usb webcam and the external usb webcam My question is
what values do I put in the camera config files camera1.conf and
camera2.conf for videodevice This is the results from v4l2-ctl
--list-devices:
v4l2-ctl --list-devices
GENERAL - UVC : GENERAL - UVC (usb-0000:00:14.0-4):
/dev/video0
/dev/video1
/dev/media0
Laptop_Integrated_Webcam_HD: In (usb-0000:00:1a.0-1.4):
/dev/video2
/dev/video3
/dev/media1

Try one by one to see which one works :)
However I recommend to use V4L name by id or path instead of
/dev/video0, /dev/video1. Because those name may swap after reboot
Try:
ls /dev/v4l/by-id/*
