This feature can be used with dnn detection by setting vf_drawtext's option text_source=side_data_detection_bboxes, for example: ./ffmpeg -i face.jpeg -vf dnn_detect=dnn_backend=openvino:model=face-detection-adas-0001.xml:\ input=data:output=detection_out:labels=face-detection-adas-0001.label,drawbox=box_source= side_data_detection_bboxes,drawtext=text_source=side_data_detection_bboxes:fontcolor=green:\ fontsize=40, -y face_detect.jpeg Please note, the default fontsize of vf_drawtext is 12, which may be too small to be seen clearly.
