[FFmpeg-user] Convert m4a to mp3

[Bhavin Mistry]

Hello,

I want to conver m4a file to mp3.
I use following command, from my php file

$cmd="ffmpeg -i from.m4a to.mp3";

exec ($cmd);


But converted sound is somethink junk.
I can not describe it properly, but it feels like it plays very fast.

Can anyone help me with this?
