Field Documentation

◆ batch_index

guint NvDsPreProcessUnit::batch_index = 0

Index of the frame in the batched input GstBuffer.

Not required for classifiers.

Definition at line 234 of file includes/nvdspreprocess_interface.h.

◆ converted_frame_ptr

gpointer NvDsPreProcessUnit::converted_frame_ptr = nullptr

Pointer to the converted frame memory.

This memory contains the frame converted to RGB/RGBA and scaled to network resolution. This memory is given to Output loop as input for mean subtraction and normalization and Tensor Buffer formation for inferencing.
