Is there a codec viewer for .mp4 container?

I know this is can be done so easily if it's an avi file, tons of app can give you planty info about the avi you input. what about mp4 format?
I tried using player to indicate at least what decoder used, but it seemed ffdshow is really a monster, it supports everything i can possiblly find and play, and doesnt tell me much about anything.

i always use mp4ui for displaying basic info about .mp4 files

mediainfo should also be able to display info about .mp4 files:

sorry, i found the link (http://forum.doom9.org/showthread.php?s=&threadid=78038) in the mp4 FAQ sticky thread. it was hard to find that one and half lines at point 16), although i have read it 3 times since last night. :o
