I'm looking for an open-source library for editing AAC metadata in M4A files (as appearing in iTunes). Specifically, I need to be able to add an album art tag. It should be something similar to id3lib, which works with ID3 tags on MP3 files.

Try looking at mp4v2. Although the code base is rather large and may be difficult to integrate into your build system, the library provides some command-line executables that you can use to modify AAC tags, including artwork.

Thanks.

Since I hadn't find any open-source library maybe open-source program, that can read and set iTunes-style metadata tags in MPEG-4 files, will help you. atomicparsley.sourceforge.net

There is also Known iTunes Metadata structure provided: http://atomicparsley.sourceforge.net/mpeg-4files.html

This discussion may also turn out helpful for you: www.hydrogenaudio.org/forums/lofiversion/index.php/t31022.html
