  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Soumettre améliorations et plugins supplémentaires

    10 avril 2011

    Si vous avez développé une nouvelle extension permettant d’ajouter une ou plusieurs fonctionnalités utiles à MediaSPIP, faites le nous savoir et son intégration dans la distribution officielle sera envisagée.
    Vous pouvez utiliser la liste de discussion de développement afin de le faire savoir ou demander de l’aide quant à la réalisation de ce plugin. MediaSPIP étant basé sur SPIP, il est également possible d’utiliser le liste de discussion SPIP-zone de SPIP pour (...)

  • Realtime ffmpeg shell output PHP

    26 septembre 2013, par matthew johnston

    Alright, I've been fighting this problem for a few days. Works fine on my local windows machine but, can't seem to get it to work on my CentOS server. My script grabs the duration of the video being converted and also grabs the current seconds it has processed inside of ffmpeg. However, it is only grabbing the "input file" of the ffmpeg output and stopping there. I have tried using both pipes (STDOUT [1] & STDERR [2]) for some reason ffmpeg likes to output on the STDERR pipe. Weird.

    $filename = "somefilename.tmp";
    
$descriptor = array(
    
    0 => array("pipe", "r"),
    
    1 => array("pipe", "w"),
    
    2 => array("pipe", "w")
    
);
    

    
$ffmpeg = "ffmpeg -i /var/www/spotloader/videos/flipped/tmp/".$file."_comb.ts -vcodec mpeg2video -acodec pcm_s16le -pix_fmt yuv422p -vtag xdvb -b:v 13000k -r 30000/1001 /var/www/spotloader/videos/flipped/tmp/".$file.".mov";
    

    
//open the process
    
$process = proc_open($ffmpeg, $descriptor, $pipes, NULL, $_ENV);
    

    
//if the process opened
    
if ( is_resource( $process ) == true )
    
{
    
    //get process status
    
    $procStatus = proc_get_status( $process );
    

    
    //if its running, let node know
    
    if ( $procStatus[&#39;running&#39;] )
    
    {
    
        //nodejs socket, nothing wrong here
    
        $this->_sendSocket(&#39;converting&#39;, array(&#39;filename&#39; => str_replace(&#39;.tmp&#39;, &#39;&#39;, $file)));
    
    }
    

    
    //while the process is running
    
    while( $procStatus[&#39;running&#39;] === true )
    
    {
    
        //there is output in the pipe
    
        if ( !feof( $pipes[1] ) )
    
        {
    
            //get the output
    
            $data = fgets($pipes[1], 128);
    
            //match the outputs duration and save it.
    
            if(preg_match(&#39;/Duration:\s([0-9]{2}:[0-9]{2}:[0-9]{2})/&#39;, $data, $matches)) 
    
            {
    
                static $duration;
    
                $duration = $this->_convertToSeconds($matches[1]);
    
            }
    

    
            //match the outputs current encoding time
    
            if(preg_match(&#39;/time=([0-9]{2}:[0-9]{2}:[0-9]{2})/&#39;, $data, $matches)) 
    
            {
    
                //convert to seconds works fine, so it is not included.
    
                $curTime = $this->_convertToSeconds($matches[1]);
    
                //nodejs socket, nothing wrong here
    
                $this->_sendSocket(&#39;update&#39;, array(&#39;percent&#39; => round( ($curTime / $duration) * 100), &#39;filename&#39; => str_replace(&#39;.tmp&#39;, &#39;&#39;, $file)));
    
            }
    
        }
    

    
        //update process status
    
        $procStatus = proc_get_status( $process );
    
    }
    

    
    //nodejs socket, nothing wrong here
    
    $this->_sendSocket(&#39;converted&#39;, array(&#39;percent&#39; => 100, &#39;filename&#39; => str_replace(&#39;.tmp&#39;, &#39;&#39;, $file)));

    FFMPEG output I'm expecting the "time=00:00:00" towards the end is what I need to capture in realtime. This is taken by running the FFMPEG command directly in the shell.

    Any ideas ? What needs changing from the switch from Windows to CentOS ?

    EDIT :
    I got this to work using popen instead. It also reduced my code. If anyone else does have a solution go ahead and post it. Thanks !

  • php auto FFmeg encoding shell scrip failing - but command works in cmd [closed]

    11 mars 2020, par altruios
    $dateString = strtotime("now");
    
$cmd = 'C:\xampp\htdocs\gameOfLife\images>ffmpeg -r 19 -f image2  -i image_%d.png output_'.$dateString.'.mov';
    
shell_exec($cmd);

    the above works in the command line-but when trying to execute in php it does nothing.
    I am not getting errors, just no result.
    but when I navigate to the folder in the command line, and run that line - it creates a video correctly.
    I’ve checked that shell_exec() is in fact available to use.
    the string outputs fine - so it’s not the date.
    is the start of the cmd correct ?
    I’m a bit green on the command line in general, and could use some clarification on where I’m going wrong.

    EDIT1 : shell_exe() executes stuff, but is not executing ffmpeg ;

    shell_exec("C:/xampp/htdocs/gameOfLife/images/image_1.png");

    opens the image.
    so the shell_exec as been changed to :

    shell_exec("C:/xampp/htdocs/gameOfLife/images/ffmpeg -r 19 -f image2  -i image_%d.png output_t2.mov");

    I’ve tried static names instead of having any date variable in there to keep things simple.

    when that text runs in the console : it works.

    however, when running it though php and the server - I can’t access ffmpeg, where I can access the calc and the image just fine through php.
    So I think I ruled out the path and access issues...

    and i can type the above and get an encoded video back if i do it though the console.
    but I can’t seem to make it run via php.
