AtomicParsley - reading, parsing and setting metadata in MPEG-4 files (and showing the MPEG-4 atom tree)

AtomicParsley is a lightweight command line program for reading, parsing and setting metadata into MPEG-4 files supporting these styles of metadata:
  • iTunes-style metadata into .mp4, .m4a, .m4p, .m4v, .m4b files
  • 3gp-style assets (3GPP TS 26.444 version 6.4.0 Release 6 specification conforming) in 3GPP, 3GPP2, MobileMP4 & derivatives
  • ISO copyright notices at movie & track level for MPEG-4 & derivative files
  • uuid private user extension text & file embedding for MPEG-4 & derivative files


I use it to display the tree structure of MPEG-4 container atoms.
