  • 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 (...)

  • Configuration spécifique d’Apache

    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

  • 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.

  • ffmpeg image to video sequence stops after 10

    18 mai 2012, par Jim

    Probably a fast anwser, but my first time trying to do this. I have 77 jpeg pictures, I have renamed them to be 000.jpg - 076.jpg. The next step is using ffmpeg and here is my command statement :

    ffmpeg -f image2 -r .1 -i %d.jpg -r 25 test.avi

    It creates an avi with 10 images for 10seconds each, why only 10 ? I've tried other iterations of %d.jpg in the ffmpeg command with no success.

    thanks for the help all !

    -Jim

    Here is the listing of the directory with the images :

    ls -l

  • Perl FFMpeg print output

    31 janvier 2012, par user346443

    Hi im using the following perl command to convert files with ffmpeg :

    system ("/usr/local/bin/ffmpeg -i $inputFile $outputFile");

    I would like to know if its possible to print the ffmpeg output ?

    Cheers

    UPDATE

    The solution was to use backticks

    my $output = qx{/usr/local/bin/ffmpeg -i $inputFile $outputFile 2>&1};
    
print $output

    This prints out the following :
