  • Amélioration de la version de base

    13 septembre 2013

    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 (...)

  • Le plugin : Gestion de la mutualisation

    2 mars 2010, par

    Le plugin de Gestion de mutualisation permet de gérer les différents canaux de mediaspip depuis un site maître. Il a pour but de fournir une solution pure SPIP afin de remplacer cette ancienne solution.
    Installation basique
    On installe les fichiers de SPIP sur le serveur.
    On ajoute ensuite le plugin "mutualisation" à la racine du site comme décrit ici.
    On customise le fichier mes_options.php central comme on le souhaite. Voilà pour l’exemple celui de la plateforme mediaspip.net :

  • DirectShow IVideoWindow can't be wider than 4096px

    25 mars 2019, par ulvesked

    I have a C# application which uses DirectShow to show play video clips. We recently tried to play a video that is 9600x1080 px and it would not show. DirectShow emits events that everything.

    We use K-Lite codec pack (1295) and utilise ffdshow libx264 as codec and video renderer. Media Player Classic using the same renderer can play the clip just fine. The latest version of our application use DirectShow.NET while the older versions call DirectShow interfaces directly. Both old and new versions of our application have the same issues.

    After some experimentation we have found out the following :

    • If the video window width is 4096px or narrower it will render video. If it is 4097 or wider it will not render any video. We tried playing a HD-clip and a 720-clip with the same results. They will play when the video window is 4096x1080 but not when the window is 4097x1080 or wider.

    • When changing resolution or graphic settings there are some flashes (a few frames) of the video when the settings is applied, so that would suggest that it is in fact playing the video but it displays only black.

    Tested on Windows 10, 64 bit.

    Any ideas of what the we can do to fix this ?

  • Package not found - add libav to PKG_CONFIG_PATH environment variable

    I am attempting to build the Parrot SDK and when running the command it continuously fails due to multiple libav package variants not being found. Below is the error message.

    As I understand it libav has been replaced by ffmpeg but the build should still be able to reference the packages as libav. I’ve tried adding different paths to PKG_CONFIG_PATH using `export PKG_CONFIG_PATH=...’ but with no success. It is possible I’m not adding the correct path, I used ’dpkg -L ffmpeg’ to locate the package. The output of that is :

    ...of which I can assume the useful part is ’/usr/bin’ which i added to my PKG_CONFIG_PATH and still the same error when building. I am running Ubuntu 18.04 LTS. I’m at a loss and have been grinding at this for the past 2 days, any help would be GREATLY appreciated. Thank you and I’m happy to provide more needed information. As a small request, I am pretty new to Linux so if you could include as many details in command line operations as possible it would help alot.

  • avfilter/vf_lensfun : add scale parameter

    avfilter/vf_lensfun : add scale parameter

    The lensfun filter wraps the lensfun library which performs
    
transformations on videos to correct for lens distortion. Often this
    
results in areas in the input being mapped to areas that fall outside
    
the boundaries of the output. The library has a parameter called scale
    
which is a scale factor applied to the output video. By decreasing it it
    
is possible to regain the areas of the video which would otherwise have
    
been lost. There is a special value of 0 which indicates that the
    
library should automatically determine a scale factor that results in
    
the output frame being filled (i.e. little or no black/unmapped areas).
    

    This patch adds a corresponding scale option to the lensfun filter which
    
is passed through to the library. The existing behaviour of using the
    
automatic value of 0 is retained as the default behaviour, while other
    
values will be passed through to the library.
