Hello! I am building a Deepstream application using python app “deepstream-test2” and want to show trajectories of pedestrians, like it is shown in this Nvidia blog:

Is there any reference code that I can use to show trajectories of tracked objects using a Deepstream based python application?

I will discuss internally and feedback later.

Thank you very much!

We haven’t the feature in default DeepStream release. Can you probe the object information and buffer those object information and draw those point onto the video?

I was able to do it myself. Thanks!

I just wanted to know what’s the max array size of “NvOSD_LineParams”, because if I add more than 20 elements, it throws an error.

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks

You can add more array into the list if the count is bigger than 16.
