ARGUS + Deepstream + Timestamps

We want to build an application that uses nvarguscamerasrc + deepstream. Accurate system time stamps are very important to us. We can get the actual image timestamps with MONOTONIC time with the argus metdata, however, it seems that deepstream only supports time stamping with NTP at some random point in time when it gets called. Is there an elegant method to associate argus time stamps with system time stamps with deepstream or do we have to develop a custom solution.
Thank you


I would suggest to sync by the APP.

I am not familiar with APP. Could you tell me a little more or give a link?

You can have search by google.
