Re: [Cin] SAR, DAR, PAR - oh, my!

I don't quite understand how ffmpeg considers the various aspect ratios. However from the site lurkertech you pointed to (and from which I had taken some definitions put in the manual) PAR and SAR are not the same thing: PAR is about pixel shape and size; SAR is about frame shape and size. To change the manual I would like to be sure that ffmpeg really considers PAR=SAR.
