Can I control bounding boxes draw or not depend on position?

I use the deepstream-test3 example to display rtsp sources, and I can get the detected object information (e.g. x,y,w,h) from obj_meta in tiler_src_pad_buffer_probe(), but I don’t see where the function that draws the rectangle of bounding boxes.

I want to control the bounding box of detected objects drawn on frame or not, depending on position of bounding box, is possible?

Pls share your setup with us?
For your question, yes I think you can modify the rect_params through a probe, refer gstnvinfer_meta_utils.cpp->attach_metadata_detector
