• SOLVED - AVI to MP4 - ffmpeg conversion

  26 mai 2014, par Emmanuel Brunet

  I’m running a debian 7.5 machine with ffmpeg-2.2 installed following these instructions

  Issue

  I’m trying to display a mp4 video inside my browser. The original file has an AVI container format. I can successfully convert it to mp4 and the targetfile is readable (video + sound) with the totem movie player. So I thought everything would be OK displaying the bellow page

  HTML5 web page

      
  
  
  
  
  
  <video width="640" height="480" controls="controls">
  
    <source src="/path/to/output.mp4" type="video/mp4">
  
  <h3>Your browser does not support the video tag</h3>
  
  </source></video>

  Input probe

  $ ffprobe -show_streams input.avi
  
  
  
    Duration: 00:08:22.90, start: 0.000000, bitrate: 1943 kb/s
  
      Stream #0:0: Audio: mp3 (U[0][0][0] / 0x0055), 48000 Hz, stereo, s16p, 64 kb/s
  
      Stream #0:1: Video: mpeg4 (Advanced Simple Profile) (XVID / 0x44495658), yuv420p, 720x540 [SAR 1:1 DAR 4:3], 1870 kb/s, 29.97 fps, 25 tbr, 29.97 tbn, 25 tbc

  Convert

  $ ffmpeg -y -fflags +genpts -i input.avi -acodec copy -vcodec copy ouput.mp4

  Html browser

  Opening the above html file plays sound but no video is displayed.

  When I use other .mp4 files, videos succesfully displayed so I’m sure I face a conversion issue.

  Not : I’ve tryed a lot of other ffmpeg options but without success.

  Any idea ?

  Thanks in advance.

  Oué, c’est l’abréviation. Les navigateurs sont intelligents et mettent entre parenthèse le contenu de l’abbréviation à l’impression. J’ai toujours trouvé très vilain ce abbr avec la date en iso dedans. Tout ça pour je ne sais quel truc de http://fr.wikipedia.org/wiki/Microformat dont on n’entend (...)

• ffmpeg throws error when trying to remove subtitle track only when artwork is present [on hold]

  2 juillet 2014, par user226372

  Hi ffmpeg users/gurus/developers,

  I am having a peculiar problem.

  I have a media with 5 tracks (Notice the fifth one is album artwork)

  Stream #0:0(und) : Video : h264 (High)
  Stream #0:1(und) : Audio : aac (mp4a / 0x6134706D), 44100 Hz, stereo, fltp, 164 kb/s (default)
  Stream #0:2(und) : Audio : ac3 (ac-3 / 0x332D6361), 44100 Hz, stereo, fltp, 224 kb/s
  Stream #0:3(eng) : Subtitle : mov_text (tx3g / 0x67337874), 1280x60, 0 kb/s (default)
  Stream #0:4 : Video : mjpeg, yuvj420p(pc), 1000x1500 [SAR 1:1 DAR 2:3], 90k tbr, 90k tbn, 90k tbc

  All i am trying is to remove the subtitle track Stream #0:3(eng) : Subtitle by this command

  ffmpeg -i input.mkv -map 0:0 -map 0:1 -map 0:2 -map 0:4 -c copy output.mkv

  as explained here

  https://trac.ffmpeg.org/wiki/How%20to%20use%20-map%20option

  But i am getting this error

  Stream mapping:
  
  Stream #0:0 -> #0:0 (copy)
  
  Stream #0:1 -> #0:1 (copy)
  
  Stream #0:2 -> #0:2 (copy)
  
  Stream #0:4 -> #0:3 (copy)
  
  [ipod @ 0x103011000] Could not find tag for codec mjpeg in stream #3, codec not currently supported in container
  
  Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument

  Conversion failed !

  If the input media doesn’t contain an artwork this error is not happening

  Any ffmpeg gurus who can help me with this issue please !!!!
