  • Keeping control of your media in your hands

    13 avril 2011, par

    The vocabulary used on this site and around MediaSPIP in general, aims to avoid reference to Web 2.0 and the companies that profit from media-sharing.

  • FATE Ends the Mac

    8 juin 2010, par Multimedia Mike — FATE Server

    Did you know Mac OS X can even blue-screen ? To be fair, it doesn’t actually present a blue screen. But when Mac OS X encounters a kernel panic, it looks like this :



    True to form, Mac just has to be prettier and glossier than other operating systems, even in the area of system crashes.

    The reason I bring this up is that the FATE system is bringing down my Mac. My Mac Mini is reliably dying every single time I try to execute my FATE client Python script. Maybe the weather is getting too warm.

    Update, 2010-6-8 : Following advice in the comments, I tried to run Memtest86 on the Mac Mini in question. I couldn’t get the machine to boot the CD I made. As an alternative, I turned the machine off and let it rest for a night. In the morning, I turned it on and ran the FATE client script. It’s working for now.

  • Adding some kind of subtitle to an mp4 with ffmpeg

    23 juin 2017, par Steven Van Ingelgem

    I have a subtitle (it certainly looks like it), but I don’t know how to add it into an MP4 I’m creating.

    I honestly have never seen anything like this before...

    So the command I’m running now is this :

    ffmpeg -y -i ’audionld#24000.mp4’ -i ’audionld#48000.mp4’ -i
    ’textnld.mp4’ -i ’video.mp4’ -map 0:a -map 1:a -map 2:d -map 3:v
    -metadata:s:a:0 language=nld -metadata:s:a:1 language=nld -acodec copy -bsf:a aac_adtstoasc -vcodec copy -c:d copy -movflags faststart "test.mp4" 2>&1

    Which results in this output :

    This gives the error :
    Could not find tag for codec none in stream #2, codec not currently supported in container
    Could not write header for output file #0 (incorrect codec parameters ?) : Invalid argument

    So I tried playing with the map like this :

    -map 2:s
    ==> Gives me :
    Stream map ’2:s’ matches no streams.
    To ignore this, add a trailing ’ ?’ to the map.

    -map 2:s ?
    ==> Gives me no error, but the subtitle stream isn’t added into the final file.

    Stream mapping:
    
  Stream #0:0 -> #0:0 (copy)
    
  Stream #1:0 -> #0:1 (copy)
    
  Stream #3:0 -> #0:2 (copy)

    Maybe I first have to convert the subtitle into srt or such, but for that I don’t find on google what type of file this is.

    Any help would be greatly appreciated !

    Thanks

    ---EDIT---

    Hereby the code that I am using to convert this in PHP :

      private function convert_TTML_subtitle_file($orig) {
    
    if ( $orig == '' || !file_exists($orig) ) {
    
      return false;
    
    }
    

    
    $f = file_get_contents($orig);
    
    $pos = stripos($f, '<tt xmlns="http://www.w3.org/ns/ttml" if="if" false="false" return="return" while="while">body->div->p as $p ) {
    
          $txt .= "{$counter}\r\n";
    
          $counter++;
    
          $txt .= $p['begin'] . ' --> ' . $p['end'] . "\r\n";
    
          $txt .= $p->span . "\r\n\r\n";
    
        }
    
      }
    
      $cur += $curSize;
    
    }
    

    
    $fname = tempnam(getcwd(), 'sub');
    
    file_put_contents($fname, $txt);
    
    return $fname;
    
  }
    
</tt>
