Answering my own question. Here I have chosen to scale from height. It is also possible to scale from width.



Code:
height=$(ffprobe -v quiet -show_entries stream=width,height -of default=noprint_wrappers=1 $filename | awk -F '=' '/height/{print $2}')
ffmpeg -i watermark2.png -y -v quiet -vf scale=$height*0.25:-1 scaled.png       #scale watermark
ffmpeg -i $filename -i scaled.png -filter_complex overlay=15:15 output.png      #add watermark
