Change bounding box color

I am using deepstream-test3. How can I change default bounding box color?

I changed as follows.

obj_meta_f->rect_params.border_color.red = 0;
obj_meta_f->rect_params.border_color.green = 1;
obj_meta_f->rect_params.border_color.blue = 0;
obj_meta_f->rect_params.border_color.alpha = 1;

But before I changed as above, default is red color. I want to change the default color.

The change looks good, what’s the issue you met?
BTW, pls share your setup with us

Before I change to green, the original color is red. Can I change original color to green?
bbox-border-color0 doesn’t work in test3 app.

My config file for deepstream-test3 is as follows.

The config item is parsed by deepstream-app, it’s not handled by gst-nvinfer plugin, so it’s expected that cannot work well for test3 app.
