    MediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
    Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...)

  • Fluent-ffmpeg "not a suitable output format"

    5 septembre 2015, par J4G

    I’m using the fluent-ffmpeg module for Node.js to convert audio files. I have a .mp3 file that I’d like to convert to .wma

    Here’s what that looks like :

    var proc = new ffmpeg({
    
   source: 'file.mp3',
    
   nolog: false
    
}).toFormat('wma')                                                
    
  .saveToFile('file.wma', function(stdout, stderr)
    
{                                                 
    
    console.log(stderr);
    
});

    Unfortunately, I get the error :

    Requested output format 'wma' is not a suitable output format

    This is the entire error log :

    I know this isn’t an ffmpeg issue because

    ffmpeg -i file.mp3 file.wma

    Works fine. Any ideas ?

  • Python to generate a video mpd file (even a node package) [on hold]

    14 mars 2017, par Junior

    I am in the midst of developing a video streaming app and I’m currently stuck at the Adaptive Bitrate Streaming part.

    Is there a python or node module that can (run server-side and) generate a mpd file of a video after it is uploaded, this way it is easy to link the file to Dash.js.

    So to clarify, I would just upload my video and have the server generate an mpd file for the video. The next time I use Dash.js, i just attach this file.

    Thanks.
