I am trying to make tracker and secondary gie work with below code. I had no problem with 1 source. I think I have problems with linkings.

Thanks.

Found better way [here](https://github.com/Ajithbalakrishnan/Deepstream-Python-Samples/blob/main/multi_usb_cam/test_v3.py)

But still can’t access sgie obj\_meta

```auto
            if obj_meta.obj_label != SGIE_CLASS_LBL_HUMANHEAD:
                obj_counter[obj_meta.class_id] += 1
            if obj_meta.obj_label == PGIE_CLASS_LBL_PERSON:
                obj_meta.rect_params.border_color.set(1.0, 1.0, 0.0, 1.0)
            if obj_meta.obj_label == SGIE_CLASS_LBL_HELMET:
                obj_counter[SGIE_CLASS_ID_HELMET] += 1
                obj_meta.rect_params.border_color.set(0.0, 1.0, 0.0, 1.0)
            elif obj_meta.obj_label == SGIE_CLASS_LBL_HUMANHEAD:
                obj_counter[SGIE_CLASS_ID_HUMANHEAD] += 1
                obj_meta.rect_params.border_color.set(1.0, 0.0, 0.0, 1.0)

```

obj\_meta.obj\_label never equals to ‘Helmet’ or ‘Human head’ so I can’t set color.  
But It works for Person

It works after below change

```auto
#tiler_src_pad=tracker.get_static_pad("src")
tiler_src_pad=sgie1.get_static_pad("src")

```
