MM camera error - libmmal.so
-
I’ve done a clean MM install that worked.
After this i installed a module todo facial-recognition with the MMM-Face-Reco-DNN module.
The problem doesn’t seem to be in the module but in MM and the picamera files escpecially the libmmal file. (https://forums.raspberrypi.com/viewtopic.php?t=324283)
Also at first the module starts good and without problems. At the moment it tries to get a picture or video the error occures.The camera does work:

When i start the mirror this error occures when it tries to use the libmmal.so file:

Some OS and version data:
