I am using deepstream_parallel_inference_app. I wonder how to add probe for getting bounding boxes of detected objects for each gie?

any reply for this? thanks

Have you look at this blog. NVIDIA Jetson and Raspberry Pi: Xavier NX-DeepStream 5.0 #4 - Handling Primary, Secondary Inference Results

1.If you can get the bbox of all detected objects in the osd sink probe, This is where the code is

2.If you want to add probe to each pgie src pad, please refer to here

Then modify the code add probe function which you want. just like

#psesudo code
NVGSTDS_ELEM_ADD_PROBE (pipeline->
        common_elements.primary_bbox_buffer_probe_id,
        bin->primary_gie_bin[i], "src",
        gie_primary_processing_done_buf_prob, GST_PAD_PROBE_TYPE_BUFFER,
        pipeline->common_elements.appCtx);
