 I'm trying to convert a .OMA file to .MP3 but no success with a specific
 file.

 If I try:
 {{{
 ffmpeg -i audio1.oma -f mp3 output.mp3
 }}}
 The file is converted successfully. The file audio1.oma is a 3 MB file.

 Full output:

 If I try the same with another .oma (53 MB) I'm getting the error:

 Both audios works fine when using the MP3 Player. The first audio which
 works is just a random song from my MP3 player to test. The second file
 was recorded in a music studio playing live with multiple channels.

 Anything I'm missing here?
