Output of nvtracker between detections

[deveso]

I am currently working with deepstream on Jetson Xavier NX with Gst-nvtracker.
The detector sometimes does not detect the object between frames.
However, the tracker works fine and assigns the correct object ID after the empty frame.

For example:

Frame[0]: ID=0, left=20, top=10
Frame[1]:
Frame[2]: ID=0, left=22, top=30
Frame[3]: ID=0, left=23, top=40

How can I get the peak location of the correlation response in Frame[1], as shown in the documentation?

In “deepstream_app.c” I only get tracker output if a detection is present.

static void
write_kitti_output (AppCtx * appCtx, NvDsBatchMeta * batch_meta)
{
...
guint64 id = obj->object_id;
float left = obj->tracker_bbox_info.org_bbox_coords.left;
float top = obj->tracker_bbox_info.org_bbox_coords.top;
...
}
