[MPlayer-users] m4a meta data

[Christopher Reder]

Is there a flag or some other setting for mplayer such that I can use it in slave mode to retrieve the meta data (title, artist, album) of a m4a file?  I can retrieve it from a mp3 file, but not m4a.  I looked via google and saw that there is a different structure for m4a in atom type format, but wondered if there was a switch or library needed to make them readable.

Thanks for the help.
