S'il vous plaît retirer -sameqça n'a pas de sens. Retirer -f mp4, c'est redondant. Ensuite, retirez -bufsize 20M sauf si vous spécifiez également les VBV maxrate. En règle générale, si vous n’avez aucune contrainte de qualité ou de débit, x264 assumera CRF 23, qui est une valeur saine par défaut.

Veuillez mettre à jour votre message et inclure les nouvelles commandes au lieu des anciennes. Existe-t-il une possibilité de télécharger le fichier exemple pour nous?

Probablement le même que FFmpeg Bogue # 968: Message d'erreur à la fin du flux asf . Envisagez de fournir un exemple supplémentaire au rapport de bogue et de tester si possible git master (le code ffmpeg le plus récent). Nous pouvons vous aider ici si vous avez besoin d'instructions.
