• FFMPEG [mp3float @ 0x7fd42f813200] Header missing

  10 février 2021, par rahi82

  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 ?

  libavcodec/libx264 : add user data unregistered SEI encoding
  MISB ST 0604 and ST 2101 require user data unregistered SEI messages
  
  (precision timestamps and sensor identifiers) to be included. That
  
  currently isn't supported for libx264. This patch adds support
  
  for user data unregistered SEI messages in accordance with ISO/IEC
  
  14496-10:2020(E) section D.1.7 (syntax) and D.2.7 (semantics).
  This code is based on a similar change for libx265 (commit
  
  1f58503013720700a5adfd72c708e6275aefc165).
