Durant mes activités personnelles, j'ai voulu un jour ranger la quantité impressionnante de MP3 que j'avais sur mon disque dur. La plupart d'entre eux avaient des noms farfelus et ne correspondait pas à la réalité. Mais heureusement, une grande majorité avais les tags ID3 renseigné. J'ai donc entrepris de les renommer en me basant sur ces tags. Mais rapidement, la tache m'est apparu fastidieuse. Et mon idée suivante à été de scripter ce renommage pour le faire automatiquement. Cela aurait été possible si tous les fichiers mp3 étaient bien formé et les tags existant. Ce qui n'est pas le cas.
La solution que j'ai retenu a été de programmer une interface conviviale me présentant toutes les données nécessaire pour que je réalise rapidement ce renommage.
Mon travail a donné ceci:
Pour réaliser cette interface, j'ai utilisé la bibliothéque graphique d'IBM:
SWT ainsi qu'une bibliothèque de traitement des tags ID3 du format MP3:
jaudiotagger.
Pour les icones utilisé, je les ai selectionné dans la librairie d'icone Human-O2 que j'ai trouvé
ici.
Le logiciel requiert la présence de
Java7 sur le poste, ainsi que
VLC d'installé.
Ensuite j'ai rédigé le code suivant:
