I just run the precedure of deepstream on jetson nx with jetpackage 4.5.1. And I try to add some additional information, such as meta->confidence in the message when running the deepstream-app， but got the number of 0 with int type.

  1. seems msg2p-newapi is set to 0. About the confidence, you need to set the value to msg_meta. please refer to osd_sink_pad_buffer_metadata_probe in deepstream-test4.
  2. about bbox coordinates, you can print bbox coordinates after generate_event_msg_meta. the value used in generate_deepstream_message_minimal is set before “nvds_add_user_meta_to_frame (frame_meta, user_event_meta);”. please refer to osd_sink_pad_buffer_metadata_probe in deepstream-test4.

Sorry for the late reply, Is this still an DeepStream issue to support? Thanks!
