  • 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 (...)

  • 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" (...)

  • Is there a way to non-linear speed-up video with ffmpeg ?

    3 mars 2020, par leoossa

    I’ve seen thousands of websites suggesting using setpts to speedup video

    ffmpeg -i input.mp4 -filter:v "setpts=0.5*PTS" output.mp4

    The thing is - I don’t want to speed-up video in a linear way. I want it to accelerate. So I want ’acceleration’ (Wiki) to be constant and ’speed’ to be growing.

    From what I’ve seen on ffmpeg docs setpts can be an equation, I tried to play with PREV_OUTPTS but with no success.
    Is it even possible to achieve that with ffmpeg ?

  • Anomalie #3456 (Nouveau) : bug sur |liens_absolus

    26 mai 2015, par Fil Up

    La fonction des liens absolus recherche bêtement src=… sur tout le contenu de la balise img, ce qui fait que si on a un data-original-src="xxxx", il ne trouve pas le src= et rate sa cible.

    Proposition de patch :

    ```
    // ne s’applique qu’aux textes contenant des liens
    // http://doc.spip.org/@liens_absolus
    function liens_absolus($texte, $base=’’)
    - if (preg_match_all(’,(<(a|link|image):space :+[^<>]*href=["\’] ?)([^"\’ ><[:space :]]+)([^<>]*>),imsS’,
    + if (preg_match_all(’,(<(a|link|image|img|script)\s[^<>]*(href|src)=[^<>]*>),imsS’,
    $texte, $liens, PREG_SET_ORDER))
    foreach ($liens as $lien)
    - $abs = url_absolue($lien3, $base) ;
    - if ($abs <> $lien3 and !preg_match(’/^#/’,$lien3))
    - $texte = str_replace($lien0, $lien1.$abs.$lien4, $texte) ;
    + foreach(array(’href’, ’src’) as $attr)
    + $href = extraire_attribut($lien0, $attr) ;
    + if (strlen($href)>0)
    + $abs = url_absolue($href, $base) ;
    + if ($href != $abs and !preg_match(’/^#/’,$href))
    + $texte = inserer_attribut($texte, $attr, $abs) ;
    +
    +
    +


    - if (preg_match_all(’,(<(img|script):space :+[^<>]*src=["\’] ?)([^"\’ ><[:space :]]+)([^<>]*>),imsS’,
    - $texte, $liens, PREG_SET_ORDER))
    - foreach ($liens as $lien)
    - $abs = url_absolue($lien3, $base) ;
    - if ($abs <> $lien3)
    - $texte = str_replace($lien0, $lien1.$abs.$lien4, $texte) ;

    return $texte ;

  • How to stream video using C/C++

    19 janvier 2015, par Arif Ali Saiyed

    I want to stream video to a file/ or memory buffer using VC++ on windows.
    Can anyone suggest easy to integrate library ?(that has one H,one LIB and one DLL).

    I am exploring the libVLC right now and gonna explore FFMPEG also.
    dont want to spend time in building these complex software fully myself, would appreciate any help/pointer/ references.

    My ultimate goal is to stream a video and consume the stream on HTML5 viewer.
    I tried streaming using VLC media player and streamed to a OGG file, I used same OGG file in a HTML5-Video tag and it worked.

    Now I want to do the streaming part using libVLC instead of VLC media player.
    I want to stream the video file to File or memory stream.

    I have found this sample https://wiki.videolan.org/Stream_to_memory_(smem)_tutorial/

    BUt unsure of how to get started ?
    1) Where do i get the libVLC.dll, libVLC.lib, libVLC.h , Is there any sample visual studio that has everything setup and I can straight begin to write the code using libVLC etc.

    2) Since libVLC is said to depdend on 200+ other libraries/modules/plugins, what will I have include and distribute with my application ?

    https://wiki.videolan.org/Contrib_Status/

    3) streaming format : above example seems to stream into PCM format, cant I get it stream in some format that has better codec and regonized by HTML5 ? For example when i tried using VLC media player , my options were as following
    :sout=#transcodevcodec=theo,vb=800,acodec=vorb,ab=128,channels=2,samplerate=44100:filedst=C :\Users\testUser\stream-output.ogg,no-overwrite :sout-keep
