  • 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 (...)

  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • 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 (...)

  • cbs : Describe allocate/free methods in tabular form

    cbs : Describe allocate/free methods in tabular form

    Unit types are split into three categories, depending on how their
    
content is managed :
    
* POD structure - these require no special treatment.
    
* Structure containing references to refcounted buffers - these can use
    
  a common free function when the offsets of all the internal references
    
  are known.
    
* More complex structures - these still require ad-hoc treatment.
    

    For each codec we can then maintain a table of descriptors for each set of
    
equivalent unit types, defining the mechanism needed to allocate/free that
    
unit content.  This is not required to be used immediately - a new alloc
    
function supports this, but does not replace the old one which works without
    
referring to these tables.

  • avfilter/vf_alphamerge : Fix double-free of AVFilterFormats on error

    7 août 2020, par Andreas Rheinhardt
    avfilter/vf_alphamerge : Fix double-free of AVFilterFormats on error

    The query_formats function of the alphamerge filter tries to allocate
    
two lists of formats which on success are attached to more permanent
    
objects (AVFilterLinks) for storage afterwards. If attaching a list
    
to an AVFilterLink succeeds, the link becomes one of the owners of
    
the list. Yet if attaching a list to one of its links succeeds and
    
an error happens lateron, both lists were manually freed, which is wrong
    
if the list is already owned by one or more links ; these links' pointers
    
to their lists will become dangling and there will be a double-free/use-
    
after-free when these links are cleaned up automatically.
    

    This commit fixes this by removing the custom freeing code ; this will
    
temporarily add a leaking codepath (if attaching a list not already
    
owned by a link to a link fails, the list will leak), but this will
    
be fixed soon by making sure that an AVFilterFormats without owner will
    
be automatically freed when attaching it to an AVFilterLink fails.
    
At most one list leaks because as of this commit a new list is only
    
allocated after the old list has been successfully attached to a link.
