Hi, based on test5, I’ve added both analytics and a custom plugin based on gst-dsexample. However, I realized that the obj_meta create in the gst-dsexample is not shown in bbox_generated_probe_after_analytics in test5. From what I can tell is it should be due to the fact that the gst-dsexample is added as the last element in deepstream_app.c.
Do I need to manually modify deepstream_app.c? If so how should I link the pipeline as I’m not very sure of it.

Yes, you need to change the place of dsexample.

That depends on where and how did you want to use the meta generated by your custom dsexample.

I process it after analytics but i want include them when i send the list of objects through generate_event_msg_meta in bbox_generated_probe_after_analytics.

So you need to insert dsexample before bbox_generated_probe_after_analytics(it is attached to analytics src pad) .
