• python ff-mpeg not working on VM

  2 août 2013, par Bob

  I have two Windows 2008 R2 64 bit servers with two different host providers (GoDaddy and company B). My python script runs successfully on GoDaddy's server. It doesn't run successfully on the server with company B.

  I installed the same software on both servers :

  • Python 2.7 for Windows 32 bit
  • NumPY module
  • SetupTools
  • EchoNest API for Windows

  The company B server is giving me an error related to an executable called en-ffmpeg.exe that uses the python ff-mpeg module. The exact error message is

  [dv @ 0x1449690]Can't determine profile of DV input stream.
  C :\Music\song1.mp3 : Error while opening file

  The song.mp3 file exists. I installed the latest Windows updates on the server with Company B but still I get the error. I believe the error is because something is not configured properly on this server (missing libraries or drivers ?). However, I don't know what that is !

  Please help :)

  UPDATED TO INCLUDE COMMAND AND ERROR OUTPUT FROM FFMPEG

  COMMAND :

  c :\Python27>en-ffmpeg -i "C :\Music\song1.mp3" -y -ac 2 -ar 44100

• Evolution #3012 (Nouveau) : Crawl-delay dans robots.txt

  3 juin 2013, par b b

  Dernièrement j’avais un site qui faisait monter énormément la charge serveur lors du passage du robot crawler de bing. Il y a pas mal d’articles sur le web qui causent du comportement "chelou" de ce bot et des problèmes de charge qu’il engendre. Perso, j’ai appliqué la règle suivante dans le robots.txt du site et depuis ce jour mon serveur ne se fait plus harceler par ce le bot de Bing (qui avant lançait jusqu’à 7requêtes/seconde) :

  1. calmer ce chacal de bingbot
  2. http://www.bing.com/blogs/site_blogs/b/webmaster/archive/2009/08/10/crawl-delay-and-the-bing-crawler-msnbot.aspx
     User-agent : bingbot
     Crawl-delay : 1

  http://www.lestaxinomes.org/robots.txt

  Cela serait peut être intéressant d’ajouter cette règle au robots.txt de SPIP ?

• FFMPEG running in Command Line but not PHP

  17 avril 2013, par Freeman

  I am using ffmpeg build for windows to make video thumbnails . The command works well in command line but not from PHP exec method. am using PHP 5.2.11

  Here is the command.

  "E:/Documents and Settings/x/WINDOWS/ffmpeg" -itsoffset -4 -v "E:/Program Files/Apache Software Foundation/Apache2.2/htdocs/bs/files/videogal/c08c3d20eeb9083ed033577bd154cba6.flv" -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 "E:/Program Files/Apache Software Foundation/Apache2.2/htdocs/bs/files/gallery/8ff43b72b932d2a34e7a6733672ad4d6.jpg" 2>&1

  Can somebody help. I checked the permissions they seem fine. GD is installed.

  The error msg is 'E:/Documents' is not recognized as an internal or external command, operable program or batch file

  Am using forward slashes in my paths except when escaping double quotes

  The PHP function

  function ExtractThumb($in, $out)
  
  {$path=dbconf::FFMPEG_PATH;
  
      $thumb_stdout;
  
      $errors;
  
      $retval = 0;
  
   echo $in;
  
      // Delete the file if it already exists
  
      if (file_exists($out)) { unlink($out); }
  
  
  
      // Use ffmpeg to generate a thumbnail from the movie
  
      $cmd = "$path -itsoffset -4 -i $in -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 $out 2>&1";
  
     echo $cmd;
  
  
  
     exec($cmd, $thumb_stdout, $retval);
  
  
  
      // Queue up the error for processing
  
      if ($retval != 0) { $errors[] = "FFMPEG thumbnail generation failed"; }
  
  
  
      if (!empty($thumb_stdout))
  
      {
  
          foreach ($thumb_stdout as $line)
  
          {
  
              echo $line . "\n";
  
          }
  
      }
  
  
  
      if (!empty($errors))
  
      {
  
          foreach ($errors as $error)
  
          {
  
              echo $error . "\n";
  
          }
  
      }
  
  }

  funny enough if I run without the $in and $out absolute path this is what I get
