[ffmpeg] encodeur mp3 inconnu(résolu)

[rafmav]

Voilà, j'ai un souci avec ffmpeg: impossible de transformer l'audio d'un film en mp3, alors qu'il est compilé pour!

Que ce soit à partir de l'audio:

Code : Tout sélectionner

ffmpeg -i "audio.wav" -acodec mp3 audio.mp3
...
Unknown encoder 'mp3'

ou à partir de la vidéo:

Code : Tout sélectionner

ffmpeg -i "film.mov" -acodec mp3 audio.mp3
...
Unknown encoder 'mp3'

Pourtant, c'est la version récupérer avec pacman, et dans la compilation, on trouve: enable-libmp3lame dans la compilation est actif:

Code : Tout sélectionner

...
  configuration: --prefix=/usr --enable-gpl --enable-libmp3lame --enable-libvorbis --enable-libfaac --enable-libxvid --enable-libx264 --enable-libvpx --enable-libtheora --enable-postproc --enable-shared --enable-pthreads --enable-x11grab --enable-libopencore_amrnb --enable-libopencore_amrwb --enable-libschroedinger --enable-libopenjpeg --enable-version3 --enable-nonfree --enable-runtime-cpudetect --disable-debug

  libpostproc   51. 2. 0 / 51. 2. 0

lame est installé, et me transforme d'ailleurs mon .wav (70,3M) en .mp3 (6,4M), mais j'aimerai le faire depuis ffmpeg.

A noter que le format audio de mpeg4 (.aac) est plus compressé (2,3M) et fonctionne.

C'est libmp3lame

[chipster]

C'est quoi ce titre de sujet ?

[rafmav]

@benjorabin: libmp3lame non trouvé sur core, community, extra ou aur. Ni rien d'approchant.

@chipster: navré, titre oublié: j'en mets un!

Note, the names of encoders and decoders do not always match, so there are
several cases where the above table shows encoder only or decoder only entries
even though both encoding and decoding are supported. For example, the h263
decoder corresponds to the h263 and h263p encoders, for file formats it is even
worse.

L'argument pour encoder en mp3 n'est pas "mp3" mais "libmp3lame", c'est ce que voulait dire benjarobin je suppose.

[chipster]

nickel pour le titre

[benjarobin]

L'argument pour encoder en mp3 n'est pas "mp3" mais "libmp3lame", c'est ce que voulait dire benjarobin je suppose.

En effet
C'est cette commande ffmpeg -i "audio.wav" -acodec libmp3lame audio.mp3

[rafmav]

Génial, d'accord: ça marche!
Merci beaucoup!

Et bien ffmpeg, en ligne de commande, fait gagner beaucoup de temps par rapport aux trucs en mode graphique!
Plus qu'à trouver comment on tronque une vidéo, mais c'est un autre sujet, et je crois que avec les options "-t" et "-ss", ça devrait le faire!

j'ai aussi trouvé ça (en anglais ): http://howto-pages.org/ffmpeg/ qui est pas mal!

PS: ça devait être dans le manuel ou un tutoriel, mais je ne trouvais pas: souvent vos conseils vont plus vite que de se farcir la documentation. Et les pages man manquent toujours d'exemples: impossible d'être exhaustifs pour leurs auteurs.
