Hi Scott!

The http://mpeg4ip.sourceforge.net/ also have created some small util

 # mp4info - display information about tracks in mp4 file
 # mp4dump - dumps contents from mp4 files
 # mp4trackdump - dumps track information
 # mp4tags - sets iTunes tag information
 # mp4art - extract iTunes cover art

I am considering implementing it in an external taglib-compatible
extension. The reason to make it external is to be able to depend on
libmp4. I need to interact with the same library when writing the
aKode-plugin so I might write a taglib extension at the same time.

I was kind of hoping that we did not forke the code and make a lot of
"special versions" and extentions, it just make the installation and
config of playeres difficult to none tech users. I`m shure the team on
mpeg4ip could give lot of info and code :)
