Looking for open-source library for editing AAC metadata (M4A files)

Question

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.

Answer 1

Hi

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

Good Luck

Answer 2

Hi

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.
