J'essaie de convertir un fichier AVI en un fichier MP4. Le flux vidéo est un XVID tandis que le flux audio est MP3.
Le problème est que le fichier MP4 résultant n'est pas lisible dans QuickTime Player sur un Mac. Il joue sur VLC. Bien que ce ne soit pas une rupture, je voudrais savoir comment entraîner de tels problèmes.
La commande et sa sortie sont les suivantes:
$ ffmpeg -i 103.avi -codec copy -f mp4 103.mp4

[mpeg4 @ 0x7fcddb018000] Video uses a non-standard and wasteful way to store B-frames ('packed B-frames'). Consider using a tool like VirtualDub or avidemux to fix it.
