Nv_osd box background color and bounding box problem

DeepStream 5.1, Nano Jetson Dev Kit

I’m trying to draw a “fence” to the nv_osd using python. Let’s consider I’m at this line:

I’m now going to add this code after Line 116 (after the print):

        pv_nosd_rect_params = display_meta.rect_params[0]
        pv_nosd_rect_params.left = 200
        pv_nosd_rect_params.top = 0
        pv_nosd_rect_params.width = 100 
        pv_nosd_rect_params.height = 480
        pv_nosd_rect_params.border_width = 2
        pv_nosd_rect_params.border_color.red = 0.0
        pv_nosd_rect_params.border_color.green = 1.0
        pv_nosd_rect_params.border_color.blue = 0.0
        pv_nosd_rect_params.border_color.alpha = 1.0

        pv_nosd_rect_params.has_bg_color = 1
        pv_nosd_rect_params.bg_color.red = 0.0
        pv_nosd_rect_params.bg_color.green = 0.0
        pv_nosd_rect_params.bg_color.blue = 1.0
        pv_nosd_rect_params.bg_color.alpha = 0.5

        display_meta.num_rects = 1

The display shown is like so, which is good, except that the background color of the box is green (alpha change is recognised):

Things are getting completely weird, if I change the width parameter to 10:

Now it seems, that the background is not recognising the width of the bounding box and applies an (estimated) width of 20 px in addition to the wrong color.

Any idea?

Common guys, this is not really a big thing, but no answer at all?..

Sorry for the late.
We are checking it and will update you ASAP. Can you also share the whole repro with us so we can save time to move on?


Do you need more instructions?

Thanks, I’m trying to repro locally.

I tried same code on a DS 5.1 docker on DGPU since I don’t have a handy Jetson Nano device and it can work well, I will find a Jetson device to see if can repro the issue.

Yes, this looks fine. Would you mind to share the docker container ID and what is a DPGU?

docker pull nvcr.io/nvidia/deepstream:5.1-21.02-devel

Any update here?

The issue did exist in Jetson platform, we are checking internally.
