I am trying to build some machine vision software inside docker containers, it has worked previously, but now both devices are not able to access the camera.
It seems to be a configuration/update problem, as it has worked previously. I am not sure which of the updates could be the culprit.
Either calling "raspistill -i test.jpg" never returns (freeze) or this error appears:
mmal: mmal_vc_shm_init: could not initialize vc shared memory service mmal: mmal_vc_component_create: failed to initialise shm for 'vc.camera_info' (7:EIO) mmal: mmal_component_create_core: could not create component 'vc.camera_info' (7) mmal: Failed to create camera_info component
As it has previously worked in the container, access to the device, and hardware-challenges are ruled out.
Any hints are appreciated.
