  • 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) (...)

  • 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 (...)

  • writeImages and renaming the images using PHP

    3 mai 2015, par Kiran Kumar Dash

    I am working on a multimedia project. So, I am having a case where I am producing a sequence of images from a string input using he code below :

    <?php
    

    
    /*** a new Imagick object ***/ 
    
    $aniGif = new Imagick();
    

    
    /*** set the image format to gif ***/
    
    $aniGif->setFormat( "gif" );
    

    
    /*** a new ImagickPixel object for the colors ***/
    
    $color = new ImagickPixel( "white" );
    

    
    /*** set color to white ***/
    
    $color->setColor( "white" );
    

    
    $colorarray =array("white", "red", "blue" , "aqua", "fuchsia", "gray", "lime", "maroon", "navy", "orange", "purple", "silver", "teal", "yellow",  "green", "maroon", "green", "olive");
    

    
    /*** the text for the image ***/
    
    $string = "Hello Kiran Kumar";
    

    

    
    /*** a new draw object ***/
    
    $draw = new ImagickDraw();
    

    
    /*** set the draw font to helvetica ***/
    
    $draw->setFont( "./SociaLAnimaL.ttf" );
    

    
    /*** set the draw font to helvetica ***/
    
    $draw->setFontSize( "100" );
    

    
    /*** loop over the text ***/
    
    for ( $i = 0; $i <= strlen( $string ); $i++ )
    
    {
    
        /*** grab a character ***/
    
        $part = substr( $string, 0, $i );
    

    
        /*** a new ImagickPixel object for the colors ***/
    
        $color = new ImagickPixel( "white" );
    

    
        /*Generate random number for random color*/
    
        $randomNumber = rand(0,16);
    

    
        /*** create a new gif frame ***/
    
        $aniGif->newImage( 1920, 1200, $colorarray[$randomNumber] );
    

    
        /*** add the character to the image ***/
    
        $aniGif->annotateImage( $draw, 960, 600, 0, $part );
    

    
        /*** set the frame delay to 30 ***/
    
        $aniGif->setImageDelay( 30 );
    

    
    }
    
     /*** write the file ***/
    
        $aniGif->writeImages($directory.'kiran.jpg', $out);
    

    

    

    

    
    echo 'all done';
    

    
?>

    Now the problem is the writeimages object is generating images as kiran-0.jpg, kiran-1.jpg, kiran-2.jpg and so on. but what I am expecting is kiran001.jpg, kiran002.jpg, kiran003.jpg...and so on so that I can create a video out of it in while maintaining the sequence.Here is the code for video creation :

    <?php
    
$ffmpeg= "/home/kiran/bin/ffmpeg";
    
    echo exec("$ffmpeg -f image2 -framerate 2/1 -pattern_type glob -i \"/var/www/html/fftest/getthumbnail/tmp/animate/est/*.jpg\" -i \"/var/www/html/fftest/getthumbnail/audios/audio1.mp3\" -c:v libx264 -c:a copy -shortest  -s 1920x1080 -r 60 -vf \"format=yuv420p\" \"/var/www/html/fftest/getthumbnail/output/animatedaudiocolor21.avi\" 2>&1" , $output, $return);
    
?>

    As you can see I am using -pattern type glob to select all the images, but this is getting confused with he naming sequence of kiran-0, kiran-1.

    So, what I am expecting here is how can I use writeimage object o name my images as the way mentioned above. so that I can use kiran%03d.jpg in my ffmpeg command instead of *.jpg.

    Or if any one can help me providing a code so that I can rename all the images in the expected manner.I tried the below code to rename all images :

    <?php
    
$fileFolder="/fftest/getthumbnail/tmp/animate/test";
    
$directory = $_SERVER['DOCUMENT_ROOT'].$fileFolder.'/';
    

    
$i = 001; 
    
$handler = opendir($directory);
    
while ($file = readdir($handler)) {
    
    if ($file != "." && $file != "..") {
    
        $newName = 'kiran'.$i ;
    
        rename($directory.$file, $directory.$newName); // here; prepended a $directory
    
        $i++;
    
    }
    
}
    
closedir($handler);
    

    
?>

    But the code is unable to rename the images in sequence.

    Help please...

  • How to integrate Netflix audio isma and video ismv files into a single file ?

    25 juillet 2012, par Ωmega

    Having Netflix audio .isma file and video .ismv file, how can be those separate files be integrated into a single .mp4 or .flv file ? Is there some schema or algorithm that can be used to develop such a tool, or is there already a tool available ?

    I tried to use ffmpeg as follows :

    # ffmpeg -i in.isma -i in.ismv out.mp4

    Even there is no audio error shown in the above response, I was unable to convert the single audio .isma file into mp3 or other audio format file. I assume these isma/ismv files are somehow crypted or encoded in non-standard format. Below is a partial dump of audio file.
