cherche convertisseur audio mp3 ? ( résolu )

bonjour à tous

je recherche un convertisseur audio mp3 sous ubuntu . à la base j'utilise le plugin downloadhelper de firefox , mais la fonction conversion ne fonctionne pas , j'ai ce message

" La conversion nécessite une application externe qui semble absente de votre système. "
Configurer la conversion ?

par la suite je ne peux rien configurer contrairement à ce que semble dire le message . à priori c'est lié a la version qui est installé sur ma machine : /usr/bin/ffmpeg

donc je suis un peu obligé d'abandonner ce plugin qui en dehors de ça et souple et pratique . je cherche donc un logiciel souple et facile lui aussi pour convertir les fichiers flv en mp3 par ex . j'ai essayé d'en installer beaucoup , mais je n'ai pu en finaliser aucun ( toujours un élément manquant ou un problème ) je pourrais spécifier lequels selon le logiciel que vous me conseiller . je bloque donc avec tous ces logiciels lors de l'installation , je bloque à ce môment la , donc je n'en ai finalement testé aucun !

pourriez vous donc me conseiller celui qui vous semble le plus fiable , disponible ou dans la logitheque ou par le terminal , ou les paquets synaptic ... peu importe le moyen , si au final j'arrive à compléter une installation

merci d'avance de votre aide

Salut
ce que tu demande n'est pas vaiment convertir
le flv, c'est de la video
toi tu veux simplement extraire l'audio d'une video

Pour faire ça, j'ai un script bien pratique

ouvre gedit et colle ce texte dedans

#!/bin/bash

#Script Type: Nautilus Script
#Title: Extract Audio
#Dependencies: ffmpeg, zenity
#Author: jim lewellyn (styyle14)

#General Info:
#In naultius scripts, the variable $1 is given to the first file selected, then variable number increases as order of files selected does
#In naultius scripts, the variable $# is given to the number of files selected
#The usage of the action: "shift" decreases $# by 1 makes each variable shift down 1 (e.g. the contents of variable $2 become the contents of variable $1 and so forth)
#zenity is used to create pop-up windows to guide the user through the process (usage is fairly obvious)

#this title will be used for all zenity pop-up windows
title="Extract Audio"

#this part tests to see if ffmpeg is installed, andif not close the script with an error
test_ffmpeg=`which ffmpeg | grep -c "ffmpeg"`
if [ "$test_ffmpeg" -eq "0" ]; then
	zenity --error --title="::Error::" --text="You do not have ffmpeg installed.
	This package is a dependency of this script.
	Please install ffmpeg and try again."
	exit
fi

#this is necessary to handle files with spaces in the name
#default is IFS=$" \t\n" (notice the literal space before "\t")
IFS=$'\t\n'

#this variable defines the text to be used for selections in zenity windows where the user will then type in their own input option
option1="Define your own"

#these options define the height and width of each zenity window so that the ok button appears in the same place for all windows
#not used on windows where user input his/her own value
height="500"
width="500"

#these functions create zenity windows to help define the name, format, bitrate, and number of channels

tu l'enregistre avec le nom que tu veux (par exemple extraire audio)
cliqc droit dessus=>propriété=>permission et coche : autoriser l'execution

puis tu met ce fichier dans: /home/$USER/.local/share/nautilus/scripts/

Si tout va bien, un clique droit sur ta video=>script=>extraire audio
et tu as ton fichier mp3 a coté de ta video

Re : cherche convertisseur audio mp3 ? ( résolu )

merci à tous de vos réponses . je vais utiliser la méthode clipconverter qui finalement fait bien son travail , simple , rapide . un site à recommander ( si on ne fait pas ça de façon quasi professionnelle et continu ) , en même temps ça n'est pas vraiment un métier !
