Bonjour,
Voici un petit script pour convertir des fichiers audio (tout format pris en charge par gstreamer) en mp3 au debit de son choix.
A mettre dans ~/.gnome2/nautilus-scripts/Convertir en mp3 (et en executable..)
Apres il vous suffit dans Nautilus de selectionner les fichiers a convertir et click droit (script/Convertir en mp3)
Il n'y a pas besoin de se trouver "dans" le repertoire ou les fichiers sont.. on peut les selectionner n'importe ou.
#!/bin/bash
# dependances: zenity gstreamer-tools
LOC=$(zenity --file-selection --directory --title="Selectionner un repertoire") || exit
RATE=$(zenity --list --radiolist \
--height=400 \
--text="debit en kb/s" --title="Selection du debit mp3" \
--column="Selection" --column="Debit" \
FALSE 32 FALSE 48 FALSE 56 FALSE 64 FALSE 80 FALSE 96 FALSE 112 TRUE 128 FALSE 160 FALSE 192 FALSE 224 FALSE 256 FALSE 320 \
) || exit
IFS=$'\n'
for FILENAME in $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS
do
TARGET="$(basename $FILENAME)"
TARGET=${TARGET%.*}.mp3
if [ -e "$LOC"/"$TARGET" ]
then
zenity --error --text="Echec: $LOC"/"$TARGET existe deja."
else
{ gst-launch filesrc location="$FILENAME" ! decodebin ! audioconvert ! lame bitrate=$RATE ! filesink location="$LOC"/"$TARGET"; \
echo Termine. ; } \
| zenity --text-info --title "MP3 conversion output" --width=500 --height=500
fi
done
Edit:
Ci-dessous, version amelioree prenant en charge les sous-repertoires et les tags ID3... Lire les commentaires dans l'entete pour voir les dependances...

# 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 a progression bar will appear.
# A log file ~/mp3-convert.log will be created.

LOGFILE=~/mp3-convert.log
