Why deepstream-app convert image from I420 to NV12 before feeding to NvInfer?

Accelerated Computing Intelligent Video Analytics DeepStream SDK

This is pipeline grab that I exported when running deepstream-app sample (Sorry I can’t upload full pipeline because it is too large), my model used in Nvinfer is YOLOv7 or YOLOv4 trained by sRGB image. I see that Nv12 image format is feeded to model, Dose it affects to accuracy (mAP)?

please refer to the doc. nvinfer can accepts batched NV12/RGBA buffers from upstream.
