    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • 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" (...)

  • Missing headers/libraries when crosscompiling ffmpeg

    3 décembre 2016, par Ben

    I get a bunch of missing headers/libraries when crosscompiling ffmpeg for the raspberry pi.

    I couldn’t find those by googling.
    Can you tell me which packages i need to install ? My host is running on debian.

    Thanks in advance,
    Ben

    gdigrab : Fix hwnd parameter issues

    Converting from an integer to HWND (which is a pointer) requires
    
an explicit cast, otherwise Clang errors out like this :
    

        src/libavdevice/gdigrab.c:280:14 : error : incompatible integer to pointer conversion assigning to 'HWND' (aka 'struct HWND__ *') from 'long' [-Wint-conversion]
    
      280 |         hwnd = strtol(name, &p, 0) ;
    
          |              ^ 
    

    (With GCC and MSVC, this was a mere warning, but with recent Clang,
    
this is an error.)
    

    After adding a cast, all compilers also warn something like this :
    

        src/libavdevice/gdigrab.c:280:16 : warning : cast to 'HWND' (aka 'struct HWND__ *') from smaller integer type 'long' [-Wint-to-pointer-cast]
    
      280 |         hwnd = (HWND) strtol(name, &p, 0) ;
    
          |                ^ 
    

    On Windows, long types are 32 bit, so to get a usable pointer, we
    
need to use long long. And interpret it as unsigned long long
    
while at it - i.e. using strtoull.
    

    Finally, right above it, the code triggered the following warning :
    

        src/libavdevice/gdigrab.c:278:15 : warning : mixing declarations and code is incompatible with standards before C99 [-Wdeclaration-after-statement]
    
      278 |         char *p ;
    
          |               ^

  • FFmpeg Concat Filter High Memory Usage

    14 février 2020, par user2248702

    I’m using FFmpeg to join many short clips into a single long video using the concat filter. FFmpeg seems to load all clips into memory at once and quickly runs out of RAM (For 100 clips it eats over 32GB). Is there a way to limit the memory used by the concat filter ?

    The command I would use for 3 inputs is as follows :

    ffmpeg -i 0.mp4 -i 1.mp4 -i 2.mp4 -filter_complex "[0:v][0:a][1:v][1:a][2:v][2:a]concat=n=3:v=1:a=1" out.mp4

    It seems to use around 200MB per additional input, which quickly uses all the memory in my system.
