Issue Description

I used trtexec tool to convert dla engine with standalone mode and the input of dla engine is int8:dla_hwc4

My question is, how to pass nvscibuf after nvmedia image processing as dla’s input ?
Since the nvscibuf object with attribution of image has datatype of uint8, but dla engine need inputs with datatype of int8.

Is there any other way besides map uint8 data to int8 data on cpu/cuda ?
