  • 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.

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • 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 (...)

  • Unable to link with libx264.lib static library

    3 novembre 2013, par dtumaykin

    I’m building custom video encoder using x264 as a static library. I’ve followed this guide in order to build static library. Trying to compile this :

    x264_t * setup_encoder(int width, int height){
    
    x264_param_t param;
    
    x264_param_default_preset(&param, "veryfast", "zerolatency");
    
    param.i_threads = 1;
    
    param.i_width = width;
    
    param.i_height = height;
    
    param.i_fps_num = 26;
    
    param.i_fps_den = 1;
    
    // Intra refres:
    
    param.i_keyint_max = 26;
    
    param.b_intra_refresh = 1;
    
    //Rate control:
    
    param.rc.i_rc_method = X264_RC_CRF;
    
    param.rc.f_rf_constant = 25;
    
    param.rc.f_rf_constant = 25;
    
    param.rc.f_rf_constant_max = 35;
    
    //For streaming:
    
    param.b_repeat_headers = 1;
    
    param.b_annexb = 1;
    
    x264_param_apply_profile(&param, "baseline");
    

    
    return x264_encoder_open(&param);
    
}

    Results in :

    main.obj : error LNK2019 : unresolved external symbol "int __cdecl x264_param_default_preset(struct x264_param_t *,char const *,char const *)"

    main.obj : error LNK2019 : unresolved external symbol "int __cdecl x264_param_apply_profile(struct x264_param_t *,char const *)"

    main.obj : error LNK2019 : unresolved external symbol "struct x264_t * __cdecl x264_encoder_open_136(struct x264_param_t *)"

    %PROJECT_DIR% : fatal error LNK1120 : 3 unresolved externals

    Linker scans libx264.lib, but can’t find anything inside.

    Searching .\lib\libx264.lib:

    With dumpbin /HEADERS I can actually find the declaration I need, but linker is unable to do it.

  • ffmpeg options for playing in iPad WebView with tag

    19 septembre 2013, par Waynn Lue

    I'm trying to convert a video to be played in a tag in a WebView in iOS. I've tried the options at this link but it still doesn't seem to play. I've found videos that do successfully play, though, so I'm sure it's possible, I just can't seem to get any working. Here's the ffmpeg -i output for something that works.

    Here's what I tried from the wiki :

    ffmpeg -i {filename} -acodec aac -ac 2 -strict experimental -ab 160k -vcodec libx264 -preset slow -profile:v baseline -level 30 -maxrate 10000000 -bufsize 10000000 -b 1200k -f mp4 -threads 0 {filename}.ipad.mp4

    But the file doesn't play in the WebView.
