Próbuję przekonwertować plik AVI na plik MP4. Strumień wideo to XVID, podczas gdy strumień audio to MP3.
Problem polega na tym, że wynikowego pliku MP4 nie można odtwarzać w programie QuickTime Player na komputerze Mac. Gra na VLC. Chociaż nie jest to przełom, chciałbym wiedzieć, jak rozwiązać takie problemy.
Polecenie i jego wynik są następujące:
$ 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.
