I want to get the frame and need to convert as a base64…

You can access the frame buffer by the method mentioned in DeepStream SDK FAQ - #17 by mchi

But you need to crop the object by yourself.

@RajeshMuthuswamy There will be a lot of resources of base64 encoding in Google. It has nothing to do with deepstream or even with any Nvidia platform.
