Hi to all,

Which metadata from MPEG-4 is displayed in the "Extra Metadata" tab of the "Media Information" panel?

Are there any particular MPEG-4 boxes where VLC reads metadata from?

I'm trying insert different kinds of metadata into a MPEG-4 audio file and want VLC to display it as "Extra Metadata".
The usual metadata such as title or artist are no problem. They are displayed in the basic media information.
But I could use a little help finding the right place in the m4a file where to put additional information.
Any help is appreciated.

[UPDATE: On a related topic: Where in the source code do I have to look to alter what is displayed in that "Extra Metadata" tab?]

Thanks, MyKey_

modules/demux/mp4/ is the place to look for.

And use vlc_meta_AddExtra( ) function defined in vlc_meta.h

Thanks,
exactly what I was looking for.

Great! Have fun hacking, and don't forget to post patches!
