I have a general question regarding NvMOTStreamId. I am referencing this stream index in my custom tracker library. I printed out this NvMOTStreamId for each of 4 streams, and it shows id as: [0, 4294967296, 8589934592, 12884901888]. I notice these IDs are the multiples of 2^32 x [0, 1, 2, 3]. May I ask why it’s designed like by these multiples?

Is there any update on this question? I want to know if these IDs are reliable not, since I am going to map it into [0, 1,2,3] for the stream index in my custom tracker library. I would appreciate your answer!

Sorry for the late response, have you managed to get issue resolved or still need the support? Thanks

Sorry I still need to get a confirmation from Nvidia. Since this stream id in this api is not documented, I just wonder if these ids are reliable to call in my function.
