  • Demande de création d’un canal

    12 mars 2010, par

    En fonction de la configuration de la plateforme, l’utilisateur peu avoir à sa disposition deux méthodes différentes de demande de création de canal. La première est au moment de son inscription, la seconde, après son inscription en remplissant un formulaire de demande.

  • 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['running'] )
    
    {
    
        //nodejs socket, nothing wrong here
    
        $this->_sendSocket('converting', array('filename' => str_replace('.tmp', '', $file)));
    
    }
    

    
    //while the process is running
    
    while( $procStatus['running'] === 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('/Duration:\s([0-9]{2}:[0-9]{2}:[0-9]{2})/', $data, $matches)) 
    
            {
    
                static $duration;
    
                $duration = $this->_convertToSeconds($matches[1]);
    
            }
    

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

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

    
    //nodejs socket, nothing wrong here
    
    $this->_sendSocket('converted', array('percent' => 100, 'filename' => str_replace('.tmp', '', $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 ?

    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 !

  • FFMPEG enocde flv with alpha channel

    25 octobre 2013, par tree

    I'm trying to encode a video (mov) to an flv with alpha channel in FFMPEG but I can't seem to either

    1. find a codec that is supported
    2. find one that actually maintains the alpha

    Does anyone know how to set that up ?

    Thanks,

    ffmpeg -i abc_btr_1280x800_Takeover.mov -vcodec flv -pix_fmt yuv444p -s 1280x800 test4.flv
