• ffmpeg convert images to mp4 error

  31 mai 2013, par Ryan Saxe

  So I have a script that grabs a bunch of images from the web and then converts them into a movie. Yet I get a whole bunch of errors when I run it.

  First let me show what I am running and then I will post the error because it's huge :

  #for gif
  
  #call('convert -set delay 5 -loop 0 ' + folder + '*.jpg ' + name + '.gif', shell=True)
  
  #for mov
  
  #call('convert -quality 100 ' + folder + '*.jpg ' + name + '.mov', shell=True)
  
  #for organized movie
  
  call('ffmpeg -r 10 -b 1800 -i ' + folder + '%0' + str(size) + 'd.jpg ' + name + '.mp4', shell=True)

  So the commented out versions work fine, but I need to use the 3rd version ! Here is the response I get from ffmpeg :

  repeated about 30 times, but i cut it out of the traceback because it was overwhelming.

  Question : What did I do wrong and how do I fix it ?

  Edit :

  I download the jpeg files using the urllib python library's urlretrieve. This is how I save them :

  for src,name in zip(urls,range(len(urls))):
  
      file_name = folder + str(name) + '.jpg'
  
      urlretrieve(src, file_name)

• Anomalie #3056 (Nouveau) : Admin restreint : les restreindre rééllement

  13 septembre 2013, par Maïeul Rouquette

  Comme le fait remarquer http://comments.gmane.org/gmane.comp.web.spip.user/184403, il est accès étonnant qu’un admin restreint puisse modifier autre chose que le contenu de la rubrique dont il est admin.

  Il serait bon que l’autorisation d’édition sur tout les objets hors rubrique de restriction soit inexistante pour les admin restreint (sauf objet dont il est lui-même auteur, of course)

• FFMPEG for APACHE 2.4.6 (x64), PHP 5.5 (x64), MYSQL 5.6 (x64) on WINDOWS 8 (x64) MACHINE

  FFMPEG for APACHE 2.4.6 (x64), PHP 5.5 (x64), MYSQL 5.6 (x64) on WINDOWS 8 (x64) MACHINE

  I need to install FFMPEG on my windows 8 machine running DRUPAL ZEN custom theme. Can someone tell me where I can get the right dll files for this purpose ? If I have to compile them myself, can someone please give me step by step instructions for how to do so ? I have searched endlessly for these dlls for days now and I have no instructions for creating what i need manually. I have a windows machine running minGW.

  I already tried using the FFMPEG dlls that are out there on teh internet but my PHP-APACHE installations seem to be unable to properly detect the FFMPEG libraries (i added php_ffmpeg.dll to EXT folder, and the rest of hte DLLs to the WINDOWS/SYSTEM32 folder).

  I am running the following versions of PHP and APACHE. Thank you very much in advance for any help you can offer me.

  PHP Version 5.5.1
  System Windows NT 6.2 build 9200 (Windows 8 Business Edition) AMD64
  Build Date Jul 18 2013 11:04:03
  Compiler MSVC11 (Visual C++ 2012)
  Architecture x64

  APACHE VERSION
  Server version : Apache/2.4.6 (Win64)
  Apache Lounge VC10 Server built : Jul 16 2013 11:31:50
