Ok. C'est fait, les arborescences sont maitenant prises en charges.
Donc. On selectionne les fichiers et/ou repertoires dans Nautilus.
Ensuite on clique droit / Scripts / Convertir en mp3
Une fenetre de selection de repertoire s'ouvre alors. On ne peut selectionner qu'un seul repertoire ici. Celui ou les fichiers convertis seront mis.
Ensuite une fenetre de selection du debit s'ouvre.
Tout se passe ensuite en tache de fond.
Un fichier de log est cree: ~/mp3-convert.log (a consulter pour voir les eventuelles erreurs rencontrees)
ogg, flac, wav, mp3, ra, aac, etc. tout format reconnu par gstreamer peuvent etre convertis!
Convertir en autre chose qu'en mp3, changer les options de codage etc.. ne demande que des changements triviaux au script. A vous de l'adapter a vos besoins.
Se6.
A mettre dans un fichier ~/.gnome2/nautilus-scripts/Convertir en mp3
et a rendre executable.
#!/bin/bash
#
# dependancies:
# zenity
# gstreamer0.10-plugins-ugly
# gstreamer-tools
#
# Usage: To use in Nautilus
# You select files and directorie in Nautilus, then you right click, script/Convert to mp3...
# A first dialog will ask you where to put the converted files
# A second one will let you select the bit rate
# Then everything will happen in the background, no other info will be printed...
# A log file ~/mp3-convert.log will be created.
