[Résolu] Encodage mp3 lame illisible avec mplayer ???
Salut,
J'essaie d'encoder une vidéo avec avidemux, en suivant à la lettre le tuto de Cyrille. Seule différence, je n'active pas la "courbe de compression dynamique" (DRC) au niveau des filtres audio, sinon avidemux plante. Ah oui, et ma version d'avidemux est un peu différente de celle du tuto, si bien que pour le choix des codecs j'ai pris Xvid4 (vidéo) et Lame (audio).
A priori, lame encode en mp3. Mais quand j'ouvre mon fichier avi avec mplayer, le son crache et mplayer me sort :
$ mplayer test.avi

Exiting... (Quit)Aucun problème si je lis la vidéo avec vlc ou totem. J'ai pas essayé d'encoder avec autre chose qu'avidemux et à vrai dire ça me lourde de faire plein de tests à l'aveugle...
En googlant un peu j'ai vu que d'autres avaient eu le même genre de problèmes avec la même version de mplayer (1.0rc1-4.1.2), mais j'ai pas vu de solution autre que d'installer une version plus récente, or c'est la seule dispo sous edgy... 
Donc si quelqu'un a une idée, merci. 
Edit : Ok, (plus ou moins, pas cherché trop loin non plus) compris. Il y a deux bibliothèques pour l'encodage, transcode et mencoder, et le premier ne gère que les mp3 CBR, quand le deuxième ne gère que les mp3 VBR/ABR. Et comme mplayer "repose" sur mencoder, avidemux (et dvdrip) doit utiliser transcode, CQFD.
