I want recieve classifier_meta_list in test3. I recieve always NULL. Why? my code: static GstPadProbeReturn tiler_src_pad_buffer_probe (GstPad * pad, GstPadProbeInfo * info, gpointer u_data) { GstBuffer *buf = (GstBuffer *) info->data; guint num_rects = 0; …

Sorry, I found my mistake. I change: tiler_src_pad = gst_element_get_static_pad (pgie, “src”); to: tiler_src_pad =gst_element_get_static_pad (nvosd, “sink”); Everything is working

Test3 sample only have one primary gie, it’s for detector, that’s why you got classifier metadata NULL. you can refer to sample, deepstream-infer-tensor-meta-test which have secondary infer, which is for classifier.

I changed the code by analogy with deepstream-test2(with 3 GIE). The image shows the names of the classification classes, but the classification metadata is empty. Where is the classifier metadata cleared? How to fix it?

see _NvDsClassifierMeta definition, OSD will fetch metadata which will include classifier meta to show on screen, that’s why you just got object lable. Data Fields NvDsBaseMeta base_meta guint num_labels number of outputs/labels of the classifier More… gint unique_component_id unique component …
