  • FFMPEG compiled binaries don't run on XP using MinGW

    10 juin 2015, par Paul Knopf

    I am trying to build windows executables/dlls for Windows XP, and they are not working. They are the correct architecture. They run fine on my Windows 8 device machine.

    I used dependency walker to find missing DLLs, and all were present.

    Here are the compiled executables I am trying to run.

    I ran the windows build script for ffmpeg.

    Here is a dumpbin /headers ffmpeg.exe

    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 :

[mp4 @ 0x7f15299c4520] 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 argumentStream mapping:
    
  Stream #0:0 -> #0:0 (copy)

  Stream #3:0 -> #0:3 (copy)
    
    Last message repeated 1 times

    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;
    
  }

  • Cloaked Archive Wiki

    16 mai 2011, par Multimedia Mike — General

    Google’s Chrome browser has made me phenomenally lazy. I don’t even attempt to type proper, complete URLs into the address bar anymore. I just type something vaguely related to the address and let the search engine take over. I saw something weird when I used this method to visit Archive Team’s site :



    There’s greater detail when you elect to view more results from the site :



    As the administrator of a MediaWiki installation like the one that archiveteam.org runs on, I was a little worried that they might have a spam problem. However, clicking through to any of those out-of-place pages does not indicate anything related to pharmaceuticals. Viewing source also reveals nothing amiss.

    I quickly deduced that this is a textbook example of website cloaking. This is when a website reports different content to a search engine than it reports to normal web browsers (humans, presumably). General pseudocode :

    PLAIN TEXT
    C :
    1. if (web_request.user_agent_string == CRAWLER_USER_AGENT)
    2.  return cloaked_data ;
    3. else
    4.  return real_data ;

    You can verify this for yourself using the wget command line utility :

    <br />
    $ wget --quiet --user-agent="<strong>Mozilla/5.0</strong>" \<br />
     http://www.archiveteam.org/index.php?title=Geocities -O - | grep \&lt;title\&gt;<br />
    &lt;title&gt;GeoCities - Archiveteam&lt;/title&gt;

    $ wget —quiet —user-agent="Googlebot/2.1"
    http://www.archiveteam.org/index.php?title=Geocities -O - | grep \<title\>
    <title>Cheap xanax | Online Drug Store, Big Discounts</title>

    I guess the little web prank worked because the phaux-pharma stuff got indexed. It makes we wonder if there’s a MediaWiki plugin that does this automatically.

    For extra fun, here’s a site called the CloakingDetector which purports to be able to detect whether a page employs cloaking. This is just one humble observer’s opinion, but I don’t think the site works too well :
