Hi I am trying to implement the deepstream-parallel inference in python…
Below is my code… I am unable to get the model inference passed to the metamux…
Can you tell me where am i correct and wrong?

I am unable to get the model inference passed to the metamux…

What does this mean?

[Ni_Fury]

I mean linking the pgie element to the metamux element.

Seems your pipeline is not correct. Please refer the attached pipeline as an example.
