I have a problem with some mp3 files. When transcoding the file with FFMPEG I get the following error:
[mp3float @ 0x7fd42f813200] Header missing
Error while decoding stream #0:0: Invalid data found when processing input
Is this a problem of the file itself, and how it is produced? Or is it a problem of FFMPEG?
Here full decoding message:

What is also noticed is that this mp3 has the cover embedded as a video stream. And there is also this weird cross mapping. Not sure if that is normal?
