  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Submit enhancements and plugins

    13 avril 2011

    If you have developed a new extension to add one or more useful features to MediaSPIP, let us know and its integration into the core MedisSPIP functionality will be considered.
    You can use the development discussion list to request for help with creating a plugin. As MediaSPIP is based on SPIP - or you can use the SPIP discussion list SPIP-Zone.

  • dnxhddec : decode and use interlace mb flag

    25 septembre 2015, par Christophe Gisquet
    dnxhddec : decode and use interlace mb flag

    This bit is 1 in some samples, and seems to coincide with interlaced
    
mbs and CID1260. 2008 specs do not know about it, and maintain qscale
    
is 11 bits. This looks oversized, but may help larger bitdepths.
    

    Currently, it leads to an obviously incorrect qscale value, meaning
    
its syntax is shifted by 1. However, reading 11 bits also leads to
    
obviously incorrect decoding : qscale seems to be 10 bits.
    

    However, as most profiles still have 11bits qscale, the feature is
    
restricted to the CID1260 profile.
    

    The encoder writes 12 bits of syntax, last and first bits always 0,
    
which is now somewhat inconsistent with the decoder, but ends up with
    
the same effect (progressive + reserved bit).
    

    Partially fixes ticket #4876.

  • ffmpeg convert any file to any file

    28 mai 2015, par Vishnu

    I Want simple command to convert any supported file to any file with little possible video compression.

    for example

    avi to mp4
    
mp4 to 3gp
    
.
    
.etc..

    I tried below code

    ffmpeg -i infile.flv outfile.3gp

    It works for some but for some other like flv to 3gp conversion it throws error like below and also output file size is very large than input.

    "Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height"

    P:s i compiled with below librareis

    ./configure --enable-version3 --enable-libopencore-amrnb --enable-libvo-aacenc --enable-libopencore-amrwb --enable-libvpx --enable-libfaac --enable-libmp3lame --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libxvid --enable-gpl --enable-postproc --enable-nonfree

  • Evolution #2798 : Notification mise à jour SPIP

    9 avril 2015, par b b

    Et hop, voici le patch à jour avec la proposition de Cedric.

    Reste à améliorer le lien. Je pense qu’on pourrait mettre en place sur spip.net une page dont le fonctionnement serait similaire à celle des téléchargements avec une url comme http://www.spip.net/fr_update

    Pour cela, il faut créer un article en fr (pour commencer) qui reprend les propositions de Nicolas par ici :

    http://www.spip.net/ecrire/?exec=rubrique&id_rubrique=151

    Puis modifier le squelette pour qu’il prenne en charge l’url /xx_update par ici :

    http://zone.spip.org/trac/spip-zone/browser/_galaxie_/www.spip.net/squelettes/branches/2008/urls/trad.php#L8

    Ça vous semble convenable ? gogogo ?
