What do you mean by ”reset“?

The line crossing are counted and recorded internally from the start of the video, it can not be changed by application unless the pipeline restarts.

We have one question. We want to change / update a value of Line Crossing to zero, for example when the date changes. We want to know the solution.

We know the same entry as this one. - How to update/change NvDsAnalytics metadata?

OSD is attached separately as display meta user needs to modify the display_meta of the object

We would like to know the details of this entry.
Thanks.

All things need to be displayed are in NvDsDisplayMeta including line crossing, ROI, directions,… They are all lines, arrows and texts mixed together in NvDsDisplayMeta, I don’t think you can identify which lines and texts are for line crossing, which are for ROI, and which are for others.

The possible resolution is to release and remove all existing NvDsDisplayMeta in frame meta and create new display meta to draw what you want.
