Version: 1.4-SVN (using KDE KDE 3.5.1) Installed from: Compiled From Sources Compiler: gcc 4.0.2 OS: Linux Failure to edit tags on .m4a files. Tags on .aac files can be edited. http://therye.org/users/mortice/test -->Acrid Avid Jam Shred - Aphex Twin for an example
m4a metadata writing is only available when linked with libmp4v2 (either from faad2 or mpeg4ip). Otherwise, m4a tag support is still r/o. You have to enable using this library explicitly by ./configure --with-mp4v2=yes --with-mp4v2-dir=/foo/bar. aac metadata is handled by the mp3 id3 code, this is the reason for the difference.
