Up MJPG-streamer 起動スクリプト 作成: 2021-01-27
更新: 2021-02-13


  • 起動コマンドが長いので,起動用シェルスクリプトをつくる:
      $ vi ~/mjpg.sh
      #!/bin/sh PORT="8080" WIDTH=$1 HEIGHT=$2 FRAMERATE=$3 QUALITY=$4 OUT="/home/pi/mjpg-streamer/www" if [ $WIDTH = "?" ]; then echo "mjpg width height framerate quality" echo "quality : 0-100" exit else mjpg_streamer \ -i "input_raspicam.so -x $WIDTH -y $HEIGHT -fps $FRAMERATE -q $QUALITY" \ -o "output_http.so -p $PORT -w $OUT" fi

      $ chmod +x mjpg.sh


  • コマンドの書式照会
      ~ $ ./mjpg.sh ?
        mjpg width height quality framerate
        quality : 0-100

  • 起動
      ~ $ ./mjpg.sh 320 240 2 10 &

      コマンドの最後の「&」は,「デーモンで起動」
      起動メッセージに対しリターンキーで,コマンドプロンプトを得る


  • ps で起動を確認
      $ ps -ef | grep mjpg pi 7685 7684 1 01:12 pts/1 00:00:01 mjpg_streamer -i input_raspicam.so -x 320 -y 240 -fps 10 -q 80 -o output_http.so -p 8080 -w /home/pi/mjpg-streamer/www
