Actually I meant when ffmpeg is running, I want to send parameters to that running ffmpeg instance and that should change the filter_complex overlay parameters in the next frame of processing.
Using expression is like hard coding parameters into ffmpeg command. I need something where I can send the variable parameters when I need it without stopping the current running ffmpeg command.
