  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • How to apply effects to RGB frame decoded using ffmpeg ?

    23 juillet 2014, par user3665376

    I wanted to apply changes in contrast,brightness,saturation values of a video while rendering on android.I am using ffmpeg for decoding my mpeg4 video.

    I have two options for applying the effects ,

    1) Apply the changes on raw YUV frames .

    2) Apply the changes to RGB frames which are created from raw YUV frames .

    Which of the above is the best approach ?

    I started with option 2 and found a utility function at libwscale/util.c which has the below signature.

    int sws_setColorspaceDetails(struct SwsContext *c, const int inv_table[4],
    
                         int srcRange, const int table[4], int dstRange,
    
                         int brightness, int contrast, int saturation);

    but the parameter specification of the above function was difficult to understand. Can anybody do a little elaboration on the parameters use in this function ?

  • Revision 337e8015c9 : Move vp9_thread.* to common. Prepare for frame parallel decoding, the reference

    7 juillet 2014, par hkuang

    Changed Paths :
     Modify /test/vp9_thread_test.cc


     Add /vp9/common/vp9_thread.c
    (from /vp9/decoder/vp9_thread.c
    :14a12be8fd5f9ee40b87afe39401c9abb3c04006)
     Add /vp9/common/vp9_thread.h

     Delete /vp9/decoder/vp9_thread.h


     Modify /vp9/vp9_common.mk


     Modify /vp9/vp9dx.mk



    Move vp9_thread.* to common.

    Prepare for frame parallel decoding, the reference count buffers
    need to be protected by mutex. Move vp9_thread.* to common
    folder so that those buffers could use cross-platform mutex
    from vp9_thread.*.
