Après avoir mis à jour ffmpeg comme @slhck l'a suggéré et essayé la commande comme suggéré par @Gyan (légèrement modifié), ffmpeg -f h264 -r 15 -i 0x5C3C3031.raw -c copy output_3031.avi J'obtiens de bonnes vidéos avi. Cependant, la durée de la sortie est un peu inférieure à la durée attendue. La vidéo originale aurait dû durer 10:54, mais la sortie ici est de 9:54. J'ai spécifié une fréquence d'images de 15 (je compare les temps avec les vidéos converties par l'outil officiel fourni et ces vidéos ont 15 fps). De plus, sur un autre fichier plus grand que j'ai essayé, la sortie aurait dû être de 59:53 mais elle était de 57:41. Voici la sortie de la commande ffmpeg -f h264 -r 15 -i 0x5C3C3031.raw -c copy output_3031.avi -
