Yes, if you wish to generate an xml file, following the official
ffmpeg documentation:
https://ffmpeg.org//ffmpeg-filters.html#libvmaf-1

I was able to generate an 'output.xml' file in my current working
directory with the example used in the docs:

ffmpeg -i distorted.mpg -i reference.mpg -lavfi
libvmaf=log_path=output.xml -f null -
