  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

    so i ask some one he told me the exec stop php script and never give me

    You can't get the progress directly if you are using exec, because the php script is stopped until ffmpeg closes. (Because exec returns the whole execution output)

    You should use popen, for being able to get the output from the process in real time (without reading any file) for parse and show the progressbar

    Here is a example for get the output:

    When you get the progress info from ffmpeg, you can use your code for parse it and show your progressbar

    this is my popen script

    &lt;?php

    $handle = popen ("ffmpeg.exe -i files/fz.mp4 -ab 192k files/vdf.mp3 2>&amp;1 ", 'r');
    $handles = (string)$handle;
    $line = "";

    while (false !== ($char = fgetc($handle)))
    {
     if ($char == "\r")
     {
       // You could now parse the $line for status information.
       echo "$line\n";
       $line = "";
     } else {
       $line .= $char;
     }
     ob_flush();
     flush();
    }
    pclose ($handle);


       //get duration of source
       preg_match("/Duration: (.*?), start:/", $handles, $matches);

       $rawDuration = $matches[1];

       //rawDuration is in 00:00:00.00 format. This converts it to seconds.
       $ar = array_reverse(explode(":", $rawDuration));
       $duration = floatval($ar[0]);
       if (!empty($ar[1])) $duration += intval($ar[1]) * 60;
       if (!empty($ar[2])) $duration += intval($ar[2]) * 60 * 60;

       //get the time in the file that is already encoded
       preg_match_all("/time=(.*?) bitrate/", $handles, $matches);

       $rawTime = array_pop($matches);

       //this is needed if there is more than one match
       if (is_array($rawTime)){$rawTime = array_pop($rawTime);}

       //rawTime is in 00:00:00.00 format. This converts it to seconds.
       $ar = array_reverse(explode(":", $rawTime));
       $time = floatval($ar[0]);
       if (!empty($ar[1])) $time += intval($ar[1]) * 60;
       if (!empty($ar[2])) $time += intval($ar[2]) * 60 * 60;

       //calculate the progress
       $progress = round(($time/$duration) * 100);

    so i dont under stand what is good for ffmpeg progressbAR

    is exec or popen

    or javascript progress bar

  • Seam carving

    13 février 2008, par Mikko Koppanen — Imagick, PHP stuff

    Today I was reading trough the ImageMagick ChangeLog and noticed an interesting entry. “Add support for liquid rescaling”. I rushed to check the MagickWand API docs and there it was : MagickLiquidRescaleImage ! After about ten minutes of hacking the Imagick support was done. Needless to say ; I was excited :)

    For those who don’t know what seam carving is check the demo here. More detailed information about the algorithm can be found here : “Seam Carving for Content-Aware Image Resizing” by Shai Avidan and Ariel Shamir

    To use this functionality you need to install at least ImageMagick 6.3.8-2 and liblqr. Remember to pass –with-lqr to ImageMagick configuration line. You can get liblqr here : http://liblqr.wikidot.com/. The Imagick side of the functionality should appear in the CVS today if everything goes as planned.

    Here is a really simple example just to illustrate the results of the operation. The parameters might be far from optimal (didn’t do much testing yet). The original dimensions of image are 500×375 and the resulting size is 500×200.

    Update : the functionality is pending until license issues are solved.

    1. < ?php
    2.  
    3. /* Create new object */
    4. $im = new Imagick( ’test.jpg’ ) ;
    5.  
    6. /* Scale down */
    7. $im->liquidRescaleImage( 500, 200, 3, 25 ) ;
    8.  
    9. /* Display */
    10. header( ’Content-Type : image/jpg’ ) ;
    11. echo $im ;
    12.  
    13.  ?>

    The original image by flickr/jennconspiracy

    result

    And the result :

    result

    Update. On kenrick’s request here is an image which is scaled down to 300×300

  • No output file when converting audio using FFmpeg in Android

    18 mars 2017, par Sha

    I’m trying to convert m4a audio file to wav using FFmpeg. The code executes fine and gives no error, but I don’t see any output file in my directory.

    This is what I am executing :

    String[] cmd = {"-y", "-i", "/storage/emulated/0/jd.m4a", "-f","wav" ,"/storage/emulated/0/DCIM/Camera/output.wav"};

    And this is what gets printed :
