Pas de son dans un mkv avec Mplayer

Bonjour à tous,
J'ai un fichier mkv dont mplayer n'arrive pas à lire le son. Sous VLC ou totem, ça marche sans soucis.
Le résultat de la commande avec mplayer :

Donc visiblement, il ne reconnait pas les codecs. Cependant j'ai d'autres .mkv que je lis sans soucis.
Un peu d'aide ne serait pas de refus.

Re : Pas de son dans un mkv avec Mplayer

Salut,

Un peu en retard, mais il semblerai que ça soit la compression de tes pistes audio qui pose problème. L'algorithme de compression (3 = Header Stripping dans Matroska) ne semble pas être implémenté par le démuxeur MKV de MPlayer.
Cependant, bonne nouvelle : il y a un autre démuxeur (plus expérimental à priori) qui marche très bien : lavf. Pour l'utiliser :

mplayer -demuxer lavf ...

Tu peux aussi l'activer par défaut pour les fichiers MKV en ajoutant :

[extension.mkv]
demuxer=lavf

dans le fichier de configuration de MPlayer (~/.mplayer/config).
