Description (last modified by Carl Eugen Hoyos)

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

If I try:

ffmpeg -i audio2.oma -f mp3 output.mp3

[oma @ 0x7f8792000000] Unsupported codec 5!
audio2.OMA: Function not implemented

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?

What plays this?

Looks like underlying codec is wma voice 2.

It's a Sony Walkman MP3 Player (around 2010).

All the files inside are .OMA and all plays well with the player.
