    lavf/id3v2enc : fix cover art display on some software

    Adding an arbitrary amount of padding bytes at the end of the
    
ID3 metadata fixes cover art display for some software (iTunes,
    
Traktor, Serato, Torq).
    

    For reference (ID3 metadata) :
    

    [ Apic frames ]                      -> cover doesn’t show up
    
[ Apic frames, Padding ]             -> ok
    
[ Apic frames, ID3 frames ]          -> ok
    
[ ID3 frames, Apic frames ]          -> cover doesn’t show up
    
[ ID3 frames, Apic frames, Padding ] -> ok

  • ffmpeg transcoding errors with an embedded cover

    31 décembre 2012, par Val Noch

    Im trying to transcode mp3 files into wav format, so that they can be used in another script.
    The script requires the file to be 44.1Khz, so i add that to ffmpeg command.

    The problem comes when a file has an embedded cover image :

     Duration : 00:05:53.85, start : 0.000000, bitrate : 319 kb/s
    Stream #0:0 : Audio : mp3, 44100 Hz, stereo, s16p, 320 kb/s
    Stream #0:1 : Video : mjpeg, gray, 938x936 [SAR 300:300 DAR 469:468], 90k tbr, 90k tbn, 90k tbc
    Metadata :
      title : 
      comment : Cover (front)
    Stream #0:2 : Video : mjpeg, yuvj420p, 88x31 [SAR 96:96 DAR 88:31], 90k tbr, 90k tbn, 90k tbc
    Metadata :
      title : 
      comment : Cover (front)

    The ffmpeg command i use is :

    ffmpeg -loglevel warning -y -i :source -vn -ac 2 -ar 44100 -f wav :dest

    So when transcoding a file this throws warnings :

    [mp3 @ 0xa0bba60] Format mp3 detected only with low score of 24, misdetection possible!
    
[mp3 @ 0xa0bba60] max_analyze_duration 5000000 reached at 5015510
    
[mp3 @ 0xa0bba60] Estimating duration from bitrate, this may be inaccurate

    The resulting wav file has some problems (perhaps wrong header info ?), i think it reports to have more frames than are in the file so the follow-up script overshoots the end of data.

    I believe the problem is with extra streams (cover images) in the mp3 file, but i cant seem to tell ffmpeg to just deal with audio.

    The file i am using for the example is :
    07-Zimmer070-KOSMORAUM-_Junior85-For_reason_forgotten.mp3 (http://archive.org/details/ZIMMER070)

    And the ffmpeg is the latest from their git repo : git ://source.ffmpeg.org/ffmpeg.git

    Many thanks for any info in advance !
