In this case I have a square video frame but want to draw a circle over it where the center of the circle is the center of the video frame and the diameter of the circle is equal to the width (and height) of the video frame. Sort of like `ffplay -f lavfi color=s=1024x1024 -vf drawbox=color=white:x=w/2:y=h/2` but with a circle instead of square.
This is not a ffmpeg solution but ...
if your need is great - you could make a bitmap img (png) w
from png to video ..maybe
