Encodage avec FFmpeg

le Mar Juin 10, 2008 12:27

Bonjour,
Comme j'ai plusieurs site qui utilisent les vidéos pour principal contenu, j'ai voulu créer un script qui lors de l'upload encode automatiquement la vidéo en .flv, le script est bon...
Cependant sur mon serveur il ne doit pas y avoir les bons codecs ou je ne sais pas car quand je veux encoder certaines vidéos elles ne marchent pas.
Voici quelques logs
Tous les formats pris en compte par FFmpeg (ffmpeg -formats)

Merci d'avance

Euh, non, c'est plutôt un bug dans un codec ou quelque part autour: "Erreur de segmentation" ça veut dire que le soft a essayé de lire/écrire en mémoire à un endroit où il ne devrait pas. Ca peut être du à un fichier mal formé (avec un codec qui ferait "un peu trop confiance" au contenu du fichier), ou à un bug déclenché dans un cas particulier ou un autre.

Un autre grand classique c'est qu'il serait à court de mémoire et ne vérifierait pas lors d'une allocation de mémoire que celle-ci s'est bien passée, et il se retrouve à écrire à l'adresse 0 (où il n'a pas le droit de le faire).

Bref, la meilleure solution est probablement que tu contactes les auteurs de ffmpeg et/ou du codec en question (sur la mailing-list qui va bien), en donnant le plus de détails possibles sur ta config, les versions utilisées, et probablement en fournissant le fichier qui cause le problème, ça leur permettra de débugguer tout ça.
