Clarification regarding information (x,y for overlay filter).

I am using ffmpeg for mobile devices so i am using flutter-ffmpeg. Now
i am using dart language for supplying x and y co-ordinates to ffmpeg
instance. Issue is, after i run the ffmpeg command, there is no way i
am able to change the coordinates, so i have to stop running ffmpeg
instance, and then re-run ffmpeg with changed coordinates.

I guess i will check for suggested solution of realtime filter and
sendcmd. I am not sure if that would work though.
