Picamera im 2 verschiedenen Python Programmen gleichzeitig nutzen.

[Kiwi_gamer01]

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:

Code: Alles auswählen

    raise PiCameraMMALError(status, prefix)

Python3 Programm:

    raise PiCameraMMALError(status, prefix)

Durch die Fehler stellt sich j araus dass immer nur ein Programm die Camera nutzen kann. Wie ändere ich das?

Indem du EIN Programm schreibst, das beide Aufgaben erledigt.

Und das in Python 3, nicht mehr in Python 2.
