Hello, Sir/Madam
I am using the deepstream-test5 in my job now, therefore, I want to know the car information about license, color and make. I have tried to look into the NvDsAnalyticsFrameMeta, but I cannot find any useful information about which track_id cross the line. My question is that How can I get tracking id when car crosses the line.

By the way, is it possible when the config file of nvdsAnalytics is changed? The program continues to run and update without having to restart the program every time.

Thank you very much.

Below is all the output of Gst-nvdsanalytics. Gst-nvdsanalytics can’t support update the config file at runtime.

  • Output
    • Original NV12/RGBA batched buffer
    • NvDsAnalyticsFrameMeta (meta containing information about individual frames in the batched buffer)
    • NvDsAnalyticsObjInfo (meta containing information about individual objects in the individual frames of batched buffer)
