When I set rect_params->bg_color.alpha to anything other than 1.0 or 0.0 I get the following error:
NvOsd ERR----line = 430 -2
I saw in the documentation that https://docs.nvidia.com/jetson/archives/l4t-multimedia-archived/l4t-multimedia-271/group__ee__nvosd__group.html#ga2c9a8f3383fd6f59163c1f9a25643ac6 Nv_OSD_Mode does not take alpha parameter into account when it is set to MODE_HW, can this be the issue? I also noticed a method “nvosd_draw_rectangles”, but I cannot find it anywhere in the Deepstream code.
Hope you can help me.
