Updating attributes of object
Answered
Hi,
I am currently exploring integration of analytics plugin to and I have trouble updating attributes of detected objects in client overlay.
I am sending one ObjectMetadataPacket with one object, this object has bounding box and name attribute with it. Everything works as expected and it is rendered in client preview:
Problem starts when I want to send delayed update of attribute for this tracked object. E.g. I want to simulate that after 100ms I send another ObjectMetadataPacket with same trackId with additonal "age" attribute.
This "age" attribute can be seen in objects tab:
but it is not updated in live video feed.
Questions:
- How can I send delayed update of additional attributes for existing tracking object that will be reflected in overlay of client ?
- Can you also please explain what is ObjectMetadataPacket::setDurationUs(int64_t durationUs) for ?
Thank you for answer.
Ivan.

Hmm it seems like it is rendering properly after all. Issue was maybe by setting wrong duration value and also bounding boxes were on same position.
I figured out that when setting duration to:
2000000
makes tracking bbox beeing shown only for 2 seconds.

Hello Ivan,
Yes, there is a delay of 2 seconds. If the timestamp of an object is more than 2 seconds in the past it won't be shown in the right-hand panel.
