Thanks for the response.

With "conventional", I just meant ANY implementation which follows the
guidelines specified as per the loudness standard other than optimised
Histogram method.

I am referring to ffmpeg\libavfilter\ebur128.c and ebur128.h in the latest
code from https://github.com/FFmpeg/FFmpeg. Is there any other
implementation within FFmpeg being used by EBU R128 scanner filter?

To me it looks like
https://github.com/FFmpeg/FFmpeg/blob/master/libavfilter/ebur128.c is
derived from
https://github.com/jiixyj/libebur128/blob/master/ebur128/ebur128.c. Later
one has an option to disable histogram method but not the version included
in FFmpeg.

I am just trying to find some documentation/reference illustrating the
details on histogram based implementation and some comparisons including
performance and output values.
