Hi all：

BSP：4.14.78

Why does video0 and video1 appear without a camera? How to delete them？

Hello gao,

Probably video0 and video1 are listed persistently in udev. I mean the file named like /etc/udev/rules.d/*-android.rules (here I replaced some digits with "*"). Please try to clean this file from /dev/video* items. or you can try  sudo rm /dev/video0 sudo mv /dev/video1 /dev/video0

Regards
