Picamera im 2 verschiedenen Python Programmen gleichzeitig nutzen.
Verfasst: Freitag 3. Januar 2020, 11:16
Wie ist es möglich die Camera gleichzeitig in einem (python2 [Motion dedection]) und in einem (python3 [Webserver stream]) Programm zu nutzen?
Wenn ich versuche beide Programme gleichzeitig laufen zu lassen bekomme ich diesen Fehler:
Python2 Programm:
Python3 Programm:
Durch die Fehler stellt sich j araus dass immer nur ein Programm die Camera nutzen kann. Wie ändere ich das?
Wenn ich versuche beide Programme gleichzeitig laufen zu lassen bekomme ich diesen Fehler:
