Ah, I didn't know about qt_tools. Does the source build on Linux?
AtomicParsley (which does build on Linux, I have built mine) apparently
allows to set arbitrary atoms. Check its "--uuid-help" page.
 Short extract:
Setting a user-defined 'uuid' private extention tags will appear in "moov.udta.meta"). These will
only be read by AtomicParsley & can be set irrespective of file branding. The form of uuid that AP
is a v5 uuid generated from a sha1 hash of an atom name in an 'AtomicParsley.sf.net' namespace.
Define & set an arbitrary atom with a text data or embed a file:
--meta-uuid There are two forms: 1 for text & 1 for file operations
setting text form:
--meta-uuid (atom) "text" (str) "atom" = 4 character atom name of your choice
str is whatever text you want to set
file embedding form:
--meta-uuid (atom) "file" (/path) [description="foo"] [mime-type="foo/moof"]
"atom" = 4 character atom name of your choice
/path = path to the file that will be embedded*
description = optional description of the file
default is "[none]"
mime-type = optional mime type for the file
default is "none"
Note: no auto-disocevery of mime type
if you know/want it: supply it.
*Note: a file extension (/path/file.ext) is required
