How to extract and calculate the framerate of the video in a mp4 container

hi, afaik, the mp4 container doesnt have a absolute moov atom describing the actual framerate of the video within, but its rather calculated based on the PTS/DTS timing values.
Are there tools, pref opensource, that can show the PTS/DTS values and do this calculation?
I know mediainfo, ffprobe etc can do it, but i want to understand where in the mp4 container this data resides..
