• [^] # Mon script en python pour ceux qui veulent

    Posté par (site web personnel) . En réponse au journal Des "basheries". Évalué à 2.

    J'utilise la librairie mutagen pour récupérer les tags du fichier flac, ainsi que l'encodeur lame. Le reste c'est du python3 de base.
    Il s'utilise comme suit:

    ./flac2mp3.py source_dir destination_dir

    Le script parcours récursivement l'ensemble du répertoire source_dir, convertit les fichiers flac trouvés en mp3 en reprenant les tags et les stocke dans le dossier destination_dir en reproduisant l'arborescence du dossier d'origine.
