Here iz an exemple in php
Ull see correct metadatatagz sample to get infoz
The script should be human readable
< ?php

-metadata artist
-metadata album_artist
-metadata album
-metadata title
-metadata genre

The MP4 file format itself does not provide any restrictions on metadata
keys. The list in my SU answer lists all the iTunes tags that our muxer
currently supports. Custom global tags are possible if
-movflags use_metadata_tags
is added to the command.
Then -metadata somekey=somevalue can be stored. I should update my
answer to reflect this. I can't test this but it's possible that Apple
applications may not read these or any other tags if this method is used.
Thanks,
Gyan
