Basically I have implemented an inference system built around deepstream-app (c version) and it is working extremely well for my use case.

I was wondering, If you have a tracker set up (NvDCF in my case), is there a way to color bounding boxes drawn to OSD based on the tracker ID assigned to each bounding box?

follow up question, if possible, is it possible to change the color mapping for track ID’s on the fly? I’m not opposed to editing app a bit if need be.

Thanks in advance,

I think you can add a probe on the src pad of nvtracker and modified the corresponding filed in NvDsDisplayMeta, you can refer NVIDIA DeepStream SDK API Reference: Main Page
