  • 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 (...)

  • Improve ffmpeg performance

    8 décembre 2014, par hitesh

    I am using ffmpeg to take screen shot from video , it is video from CDN.

    I am doing below steps

    1.Upload video to CDN using html file tag.

    2.Get CDN url and use it for creating screen shot using ffmpeg.

    3.Upload the screenshot in CDN.

    4.Save video and screenshot CDN url to DB

    the whole process is really time consuming, even if I put loader it is really slow.

    This is code of POC I did for ffmpeg :

    $imageFile = realpath("./videos") . '/test5.png';
    
$imageFile2 = realpath("./videos") . '/test6.png';
    
$size = "230x155";
    
$getfromsecond = 8;
    

    
if (isEnabled('shell_exec')) {
    
    echo "Shall_exec is enabled " . "<br />";
    
    shell_exec('echo "hello world"');
    
    echo "<br />";
    
} else {
    
    echo "shall exec command is not allowed";
    
}
    

    
$cmd = "ffmpeg -i $vid -an -ss $getfromsecond -s $size -vframes 1 $imageFile";
    
$cmd2 = "ffmpeg -i $remoteVideo -an -ss $getfromsecond -s $size -vframes 1 $imageFile2";
    

    
echo 'command 1 - local Image : ' . $cmd . "<br />";
    
echo 'command 2 - remote video : ' . $cmd2 . "<br />";
    
echo "<br />command 2 - remote video shell_exec output : " . shell_exec($cmd) . "<br />";
    
echo '<br />command 2 - remote video shell_exec output : ' . shell_exec($cmd2) . "<br />";
    

    
if (!shell_exec($cmd)) {
    
    echo " video Thumbnail created" . "<br />";
    
} else {
    
    echo "Error Creating video thumbnail" . "<br />";
    
}
    
if (!shell_exec($cmd2)) {
    
    echo "Remote video Thumbnail created" . "<br />";
    
} else {
    
    echo "Error Creating Remote video thumbnail" . "<br />";
    
}
    

    
function isEnabled($func) {
    
    return is_callable($func) &amp;&amp; false === stripos(ini_get('disable_functions'), $func);
    
}  

    Is there some way to improve ffmpeg performance ?

    Thanks

  • Creating a pipe between C# and Ffmpeg

    13 septembre 2011, par John Oliver

    I have a C# program that creates a video and saves it to the disk in real-time. Instead of doing that, I want it to write it directly in a pipe connected with ffmpeg...

    The function that keeps saving the video in the disk, which I can not control, receives an IntPtr with a reference to the file.

    So, I need to create a pipe or something like that with ffmpeg, get a pointer to that, and use that pointer in the function, so that it streams the file to ffmpeg and not the disk...

    Regards,
    John Oliver
