３年位前にMotionの記事は書いている。
「Orange Pi + WEB Cam + motion で監視カメラっぽい物を組む。」
「Orange Pi + WEB Cam + Motion を連続稼働させてみる。」
「Orange Pi + WEB Cam with Motion + SendEmail で動体検知したらメールで動画を送る。」
動体検知的な防犯カメラ的なものをまたやってみようと思いたって、思い出しながら再挑戦する。
Orange Pi PC2
Ubuntu 20.04.3 LTS (Focal Fossa)
Armbian 21.08.6 Focal 20.04
Motion 4.2.2
という環境だ。
sudo apt-get install motion
cd /etc/motion
sudo cp motion.conf motion.conf.org
sudo nano motion.conf
全部を載せておく。

videodevice /dev/video1
に変更したらあっけなく動いた。
昔、いろいろ書いてる変更点はほとんど無関係だった。
