  • MediaSPIP 0.1 Beta version

    25 avril 2011, par

    MediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
    The zip file provided here only contains the sources of MediaSPIP in its standalone version.
    To get a working installation, you must manually install all-software dependencies on the server.

    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 (...)

  • multiple processes of video processing to GPU cores

    18 août 2015, par user2522623

    Can we assign a number of processes (i.e. 100-500 processes) to GPU, each process running on a GPU core ?
    In my application of video processing, I have to use ffmpeg library to proceed video and audio. If there are like more than 100 or even 500 such independent processes, I guess it’s faster to assign each process to a GPU. However, I don’t know if we can do it, and to do it, what libraries, tools are necessary ? CUDA ?

  • Revision d190ad228f : Simplify dependencies in dspr2 related codes The common_dspr2.h should be indep

    17 juillet 2015, par Jingning Han

    Changed Paths :
     Modify /vp9/common/mips/dspr2/vp9_common_dspr2.h



    Simplify dependencies in dspr2 related codes

    The common_dspr2.h should be independent of codec-specific data
    structures.

  • Build latest version of FFMPEG with libx264 Android

    12 novembre 2016, par Biraj Zalavadia

    I was able to Build FFMPEG with libx264 Android successfully and was working well before 2 months.

    I uses halfninja for building.

    Today I take latest source of ffmpeg and libX264 from here.

    git clone git://git.videolan.org/x264.git

    git clone git://git.videolan.org/ffmpeg.git

    And try to rebuild whole project. But now it throws following errors.
