That's not what I need.
I know how to get the metadata.
but I need to include in a single mp3 file, several "tags" of the same type.
so, asked for the option-atag. to make comments from time to time in  
the audio, to show that chapter is. and the MP3 Player can jump  
between them.
I have to find a solution for it for my work and thought it could  
serve ffmpeg .
