  • 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) (...)

  • Ajouter des informations spécifiques aux utilisateurs et autres modifications de comportement liées aux auteurs

    12 avril 2011, par

    La manière la plus simple d’ajouter des informations aux auteurs est d’installer le plugin Inscription3. Il permet également de modifier certains comportements liés aux utilisateurs (référez-vous à sa documentation pour plus d’informations).
    Il est également possible d’ajouter des champs aux auteurs en installant les plugins champs extras 2 et Interface pour champs extras.

  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • Error using ffmpeg image2pipe with phantomjs to render video from webpage screenshots

    14 novembre 2016, par user1690179

    I am trying to use phantomjs with ffmpeg to complie videos from screenshots of a webpage as described here :
    https://groups.google.com/forum/# !msg/phantomjs/wluVGGjhL90/oGBXqh7QP44J

    I have the following test.js file :

    var page = require('webpage').create();
    

    
page.clipRect = { top: 0, left: 0, width: 900, height: 800};
    
page.viewportSize = { width: 900, height: 800};
    

    
var url = 'http://dl.dropbox.com/u/621993/voronoi/voronoi.html';
    
var frames = 100;
    

    
page.open(url, function(){
    
    setInterval(function(){
    
        page.render('/dev/stdout');
    

    
        if( frames == 0 ){
    
            phantom.exit();
    
        }
    

    
        frames--;
    

    
    }, 100);
    
});

    Then I run this command, taken from the link above :

    $ phantomjs test.js |ffmpeg -c:v png -f image2pipe -r 10 -sameq -i - -y test.mp4

    Including -sameq causes an error in ffmpeg, so I took it out and ran :

    $ phantomjs test.js |ffmpeg -c:v png -f image2pipe -r 10 -i - -y test.mp4

    I get the following output from ffmpeg :

    The output test.mp4 file is a blank 10 second video - just a black screen. From what i can tell, I am getting a pipe: : Input/output error from ffmpeg.

    I am pretty new to ffmpeg and I have tried changing some parameters and video codecs in the ffmpeg call, but have not found a solution yet. Can anyone advise ?

  • FFmpeg audio dont work in converted videos

    28 octobre 2013, par Bar Cumberworth

    NOTICE : when i convert videos via terminal and download them from ftp into pc the audio works fine. I use :

    if($ext == "avi" && $convert_avi == true)
    
            {
    
                $convert_source = _VIDEOS_DIR_PATH.$new_name;
    
                $conv_name = substr(md5($file['name'].rand(1,888)), 2, 10).".mp4";
    
                $converted_file  = _VIDEOS_DIR_PATH.$conv_name;
    
                $ffmpeg_command = 'ffmpeg -i '.$convert_source.' -acodec libmp3lame -vcodec libx264 -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 '.$converted_file;
    
                echo exec($ffmpeg_command);
    
                $sql = "UPDATE pm_temp SET url = '".$conv_name."' WHERE url = '".$new_name."' LIMIT 1";
    
                $result = @mysql_query($sql);
