  • Les statuts des instances de mutualisation

    13 mars 2010, par

    Pour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.
    Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...)

  • Why does recoding video with FFMPEG on Windows always give an error ?

    13 février 2016, par ALexF

    I downloaded ffmpeg from http://ramiro.arrozcru.org/ffmpeg-vfwcap-noflip.7z
    and run it with the command line : ffmpeg -r 25 -f vfwcap -i 0 output.avi

    but always get the error :

    ffmpeg -r 25 -f vfwcap -i 0 output.avi

  • Unable to execute CLI commands through PHP

    13 janvier 2012, par user940154

    OS : ubuntu 11.10
    Webserver : Apache
    Code : PHP
    I am trying to display the output of command "ffmpeg -i " on the webpage using php.
    Required : The webpage should show the information about video (text).
    Whats happening : The webpage shows no text output on running the php code.
    If I was however doing system("ls") the code runs fine and outputs the list of files.
    Here's my code

    <?php
    
 echo "Details of video file:";
    
 system('ffmpeg -i /home/atish/Videos/T2V0040006_Angled_ride_720x576i_FLDCMB.avi');
    
?>

    The same command works fine on my shell, and my system has ffmpeg installed. Here's a snapshot of executing this command directly on shell :

    I have tried appending "DISPLAY=:0" to my command and also done "xhost +" before running php code, but nothing is helping me out.

    Thanks.
