  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • HTML5 audio and video support

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.
    MediaSPIP allows for media playback on major mobile platforms with the above (...)

  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • Using FFmpeg's (libavformat) RTP data structures via dynamic linking

    15 septembre 2011, par ericreeves

    I want to use the RTP data structures (e.g. RTPMuxContext in libavformat/rtpenc.h) provided by FFmpeg's libavformat however they don't seem to be available with the following install :

    ffmpeg version 0.8.2.git, Copyright (c) 2000-2011 the FFmpeg developers
    
  built on Sep 14 2011 16:04:33 with gcc 4.2.1 (Apple Inc. build 5666) (dot 3)

  libavfilter   2. 40. 0 /  2. 40. 0
    
  libswscale    2.  1. 0 /  2.  1. 0

    When I look in /usr/local/include, I see the libavformat directory however only a few files are there : avformat.h, avio.h, and version.h. Of course, when I try to include libavformat/rtpenc.h I get "error : libavformat/rtpenc.h : No such file or directory"

    I'd like to achieve this by dynamic linking to the FFmpeg libraries (for LGPL compliance, among other reasons), but it doesn't seem to be possible.

    Is there a parameter for the configure script that I'm missing, or a post-installation step that I've neglected ?

  • 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 ?

    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 !
