Atom Viewer and Mp4 iPod Compatibility

[Pookie]

Is there a way to query a 640w h264 MP4 file to ensure it has the required uuid atom for itunes/ipod? Jongov's Quicktime Atom Viewer looks like a possible app for this, but I have no idea what to look for.

Edit - Looks like you have to be able to search for

C5 BA 39 A5 1B CF 03 23 F3

since when does the ipod/itunes need this uuid crap?

the sony psp used to need this at the beginning, but doesnt need it anymore

are you sure you are not mixing up things? or is it me? :D

No, bond you are right.

Pookie, you shouldn't need the atom viewer.

Even for the 640x480 version ? Then why the need for NicMp4Box?

Exactly PSP stopped to use them and Apple thought that it was time to re-start the show once again.
You can uses AP using -T 1 option to see an MP4 file structure, or mp4dump of the MPEG4IP toolkit.
You can find an example at AtomicParsley home page:

The UUID is a child of the avc1 box (unlike PSP they have really buried it).

How does one actually set this atom with the correct data using AtomicParsley?

EDIT: It would appear from the -T 1 output that some development version of MP4Box that I'm using sets the UUID atom with the correct data, yet iTunes still rejects the file...
