[FFmpeg-user] Problem converting video file with mp3 to mp4

[Mahmut Akcay]

I'm having problem when converting avi/flv files with mp3 audio to mp4. It
plays well with ffplay and VLC players. However, I can't hear audio when
using quicktime player.
It looks Quicktime Player doesn't like the way ffmpeg copies mp3 into mp4
file. Is there any solution for it?

Thanks in advance
