Exception with DiscoveryInterfaceEvent #177

Open jmtatsch opened 9 months ago

jmtatsch commented 9 months ago

Hello,

we run 3 Mako G 319c in an industrial setting and recently noticed the following exception after running the system for 557689 frames:

Exception ignored on calling ctypes callback function: <bound method _BaseFeature.__feature_cb_wrapper of Feature(_handle=c_void_p(1),_info=VmbFeatureInfo(name=b'DiscoveryInterfaceEvent',featureDataType=<VmbFeatureData.Enum: 3>,featureFlags= <VmbFeatureFlags.Read: 1> <VmbFeatureFlags.Undocumented: 4>,category=b'/Discovery',displayName=b'Discovery Interface Event',pollingTime=0,unit=None,representation=None,visibility=<VmbFeatureVisibility.Beginner: 1>,tooltip=None,description=b'Indicates the last interface discovery event.',sfncNamespace=b'Custom',isStreamable=False,hasAffectedFeatures=False,hasSelectedFeatures=False))>

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
IndexError: pop from empty list

What is the cause of this? Should this maybe be mitigated by checking if the list is empty before popping it?

@NiklasKroeger-AlliedVision What is the cause of this?

Teresa-AlliedVision commented 8 months ago

Are you using the latest release? Does this error happen when you connect or disconnect a camera?

jmtatsch commented 8 months ago

Yes latest release. We did not wilfully connect/disconnect any cameras. Maybe a camera resetted itself?

jmtatsch commented 8 months ago

@Teresa-AlliedVision any updates on this?

jmtatsch commented 7 months ago

@Teresa-AlliedVision @NiklasKroeger-AlliedVision What is going on with customer support? We have about 25000 € of these cameras installed. And this seems like a rather simple error to fix.

Teresa-AlliedVision commented 7 months ago

For immediate support needs, please contact customer support through us or the distributor the cameras were bought from. https://www.alliedvision.com/en/about-us/contact-us/technical-support-repair-/-rma/
