Macro Definition Documentation

◆ AV_DETECTION_BBOX_LABEL_NAME_MAX_SIZE

#define AV_DETECTION_BBOX_LABEL_NAME_MAX_SIZE   64

Definition at line 36 of file detection_bbox.h.

◆ AV_NUM_DETECTION_BBOX_CLASSIFY

#define AV_NUM_DETECTION_BBOX_CLASSIFY   4

At most 4 classifications based on the detected bounding box.

For example, we can get max 4 different attributes with 4 different DNN models on one bounding box. classify_count is zero if no classification.

Definition at line 50 of file detection_bbox.h.

unsigned int  idx 
)
static

Definition at line 84 of file detection_bbox.h.

◆ av_detection_bbox_alloc()

AVDetectionBBoxHeader * av_detection_bbox_alloc ( uint32_t  nb_bboxes,
size_t *  out_size 
)

Allocates memory for AVDetectionBBoxHeader, plus an array of nb_bboxes AVDetectionBBox, and initializes the variables.

Can be freed with a normal av_free() call.

Parameters
out_sizeif non-NULL, the size in bytes of the resulting data array is written here.

◆ av_detection_bbox_create_side_data()

AVDetectionBBoxHeader * av_detection_bbox_create_side_data ( AVFrame frame,
uint32_t  nb_bboxes 
)

Allocates memory for AVDetectionBBoxHeader, plus an array of nb_bboxes AVDetectionBBox, in the given AVFrame frame as AVFrameSideData of type AV_FRAME_DATA_DETECTION_BBOXES and initializes the variables.
