nvtracker with custom object detector.

Accelerated Computing Intelligent Video Analytics DeepStream SDK
1

In the sample, nvtracker is downstream of nvcaffegie. Is there
a way to use nvtracker with an object detector other than nvcaffegie?
What metadata would be needed from upstream for nvtracker to work?

2

Also, what metadata does nvtracker send downstream?

Hi frederickk,

Nvtracker send object id to downstream.

BBOX is needed from upstream.

Thanks

hi i have the similar problem

i developed 2 plugins
the first plugin passed the bbox to nvtracker (downstream) to be tracked
the second plugin get the tracked object from nvtracker (upstream) and draw rectangle to tracked object

[plugin1]->[nvtracker]->[plugin2]

from plugin 1 i already passed BBOX into IVA meta (type NV_BBOX_INFO) to be tracked by nvtracker once every 5 frame,
but my plugin 2 didn’t seems to get any BBOX info from nvtracker

how can i access object id from downstream (plugin 2)?

Hi,
Please check how gst-dsexample works. You should be able to get metadata by following it implementation.
