There is no such limition. Figure 1 shows the default font_size is 11, Figure 2 shows font_size is 3, the difference is very small.

11

Ok , so you agree that when font=3 , we don’t see any change from the font=11 case ?

The minimum fontsize of nvdsosd in GPU mode is 10, but there is no such limit in CPU mode.

You can try the following code.

By the way, the text is almost unreadable when the font size is set to 3. Can you share the purpose of doing this?

nvosd = gst_element_factory_make ("nvdsosd", "nv-onscreendisplay");
g_object_set(G_OBJECT(nvosd), "process-mode", 0, NULL);

We re working with thermal imaging of 640x512, we just want to have a bit more control on font size for such resolution

I will try in cpu mode and hoping it dont affect too much the pipeline latency
