  • 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.

  • 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 (...)

  • FFMPEG 'Invalid data found when processing input' while scaling an Image

    22 février 2020, par priya verma

    I just installed FFMPEG on a server and I am testing it to see if it works. I am new to this, so I don’t know if I’m doing it correctly. I want to scale and compress an image. I am doing it by following php code -

    exec("ffmpeg -i $inputImg -vf \"scale='-2':'min(480, ih)\" $outputImg 2>&1", $output, $returnStatus);
    
    print_r($output);
    
    echo '<br />'.$returnStatus;

    The thing is it works for some images and for images it gives an error. For ex. I have tried to compress an image and it returns with error -

    Am I doing it incorrectly or what ? Because it does work with some images and for some it doesn’t ! Also, is this the correct way to scale and compress an Image using FFMPEG, would love to get some insights.

  • Libvpx unknown encoder with php exec

    5 juin 2016, par Justin Tullock

    I have centos7 with ffmpeg compiled with libvpx. I can run

    ffmpeg -i gif.gif -c:v libvpx -crf 12 -b:v 500K webm.webm

    which works perfectly but when I try the same command with php exec() it returns this :

  • Why does my script return 0 when it fails ? Bash, Whisper, ffmpeg

    30 avril 2024, par d-b

    I have a bash script that executes whisper on all sound files in a directory. Whisper uses ffmpeg to decode sound files to a format it can handle. One of the files in the directory was corrupt and caused ffmpeg to fail. The first time I executed my script it returned 1 when it hit that file but when I try to reproduce the error it always returns 0.

    &#xA;

    Here is the log from the first run when 1 was returned :

    &#xA;

    When I try to reproduce the behaviour I have both tried to execute the script as well as just running the actual line of code from the command prompt. The actual script looks like this :

    &#xA;

    if whisper "$file" >> "${directory}/../${transdir}/${name}.txt"; then&#xA;    whispersuccess=$?&#xA;    echo "exit code $whispersuccess"&#xA;else&#xA;    whispersuccess=$?&#xA;    echo "exit code: $whispersuccess"&#xA;

    &#xA;

    I want it to return ¬0 when something like this happens. How do I achieve this ?

    &#xA;
