J'ai réussi à convertir la vidéo d'AVI en SWF, mais le son semble avoir été supprimé. J'exécute la commande suivante
ffmpeg -i 1.avi -b:a 3000k -vcodec flv -ab 128k -ar 44100 -acodec libmp3lame -b:a 160k -ac 2 -ar 44100 output.swf
J'ai tenté une conversion similaire de MP4 en AVI et je n'ai rencontré aucun problème.
J'utilise Windows XP 32bit
MODIFIER
J'ai inclus la sortie de ffmpeg après la conversion. La seule différence est que je tente de convertir un fichier MP4 par opposition à un fichier AVI, mais les résultats sont les mêmes, c’est-à-dire un fichier SWF avec vidéo mais pas d’audio.
