Bonjour à tous, j'essaye de faire un script de démarrage qui lance 2 applications et je suis en train de le tester pour voir si simplement le start et le stop fonctionnent:
Je souhaite lancer un exécutable compilé avec gcc et le logiciel mjpg streamer. Du coup j'ai suivi un tuto qui conseillait de récupérer le fichier d'exemple "skeleton"
mais je rencontre des petits soucis...
1. je dois passer les arguments :
-i "/root/mjpg-streamer/input_uvc.so -f 13 -r 640x480" -o "/root/mjpg-streamer/output_http.so -w /root/mjpg-streamer/www"
(tels quels dans le terminal) mais je n'arrive pas les passer dans la variable DAEMON_ARGS_2, par contre j'y arrive en y écrivant en dur... (en dé-commentant la ligne 61)
2.je n'obtiens pas les message de démarrage et d'arrêt du script.. (lignes 112 et 120, pas essayé les autres )
Je vous le mets en dessous pour que vous puissiez comprendre ce que je souhaite faire...
