nvosd_draw_arrows

Can you provide sample code nvosd_draw_arrows

https://docs.nvidia.com/metropolis/deepstream/4.0/dev-guide/DeepStream_Development_Guide/baggage/struct__NvOSD__TextParams.html#a6bff70e8db32a119551bb3c14ee55b54

We will support arrow draw in future release i.e DS5.0
Meanwhile you can add probe on src pad of osd and maybe use opencv or any other method to draw arrow on surface
