  • ANNEXE : Les plugins utilisés spécifiquement pour la ferme

    5 mars 2010, par

    Le site central/maître de la ferme a besoin d’utiliser plusieurs plugins supplémentaires vis à vis des canaux pour son bon fonctionnement. le plugin Gestion de la mutualisation ; le plugin inscription3 pour gérer les inscriptions et les demandes de création d’instance de mutualisation dès l’inscription des utilisateurs ; le plugin verifier qui fournit une API de vérification des champs (utilisé par inscription3) ; le plugin champs extras v2 nécessité par inscription3 (...)

  • 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.

  • Unhandled stream error in pipe : write EPIPE in Node.js

    28 novembre 2013, par Michael Romanenko

    The idea is to serve screenshots of RTSP video stream with Express.js server. There is a continuously running spawned openRTSP process in flowing mode (it's stdout is consumed by another ffmpeg process) :

    function spawnProcesses (camera) {
    
  var openRTSP = spawn('openRTSP', ['-c', '-v', '-t', camera.rtsp_url]),
    
      encoder = spawn('ffmpeg', ['-i', 'pipe:', '-an', '-vcodec', 'libvpx', '-r', 10, '-f', 'webm', 'pipe:1']);
    

    
  openRTSP.stdout.pipe(encoder.stdin);
    

    
  openRTSP.on('close', function (code) {
    
    if (code !== 0) {
    
      console.log('Encoder process exited with code ' + code);
    
    }
    
  });
    

    
  encoder.on('close', function (code) {
    
    if (code !== 0) {
    
      console.log('Encoder process exited with code ' + code);
    
    }
    
  });
    

    
  return { rtsp: openRTSP, encoder: encoder };
    
}
    

    
...
    

    
camera.proc = spawnProcesses(camera);

    There is an Express server with single route :

    app.get('/cameras/:id.jpg', function(req, res){
    
  var camera = _.find(cameras, {id: parseInt(req.params.id, 10)});
    
  if (camera) {
    
    res.set({'Content-Type': 'image/jpeg'});
    
    var ffmpeg = spawn('ffmpeg', ['-i', 'pipe:', '-an', '-vframes', '1', '-s', '800x600', '-f', 'image2', 'pipe:1']);
    
    camera.proc.rtsp.stdout.pipe(ffmpeg.stdin);
    
    ffmpeg.stdout.pipe(res);
    
  } else {
    
    res.status(404).send('Not found');
    
  }
    
});
    

    
app.listen(3333);

    When i request http://localhost:3333/cameras/1.jpg i get desired image, but from time to time app breaks with error :

    stream.js:94
    
  throw er; // Unhandled stream error in pipe.
    
        ^
    
Error: write EPIPE
    
    at errnoException (net.js:901:11)
    
    at Object.afterWrite (net.js:718:19)

    Strange thing is that sometimes it successfully streams image to res stream and closes child process without any error, but, sometimes, streams image and falls down.

    I tried to create on('error', ...) event handlers on every possible stream, tried to change pipe(...) calls to on('data',...) constructions, but could not succeed.

    My environment : node v0.10.22, OSX Mavericks 10.9.

    UPDATE :

    I wrapped spawn('ffmpeg',... block with try-catch :

    app.get('/cameras/:id.jpg', function(req, res){
    
....
    
    try {
    
      var ffmpeg = spawn('ffmpeg', ['-i', 'pipe:', '-an', '-vframes', '1', '-s', '800x600', '-f', 'image2', 'pipe:1']);
    
      camera.proc.rtsp.stdout.pipe(ffmpeg.stdin);
    
      ffmpeg.stdout.pipe(res);
    
    } catch (e) {
    
      console.log("Gotcha!", e);
    
    }
    
....
    
});

    ... and this error disappeared, but log is silent, it doesn't catch any errors. What's wrong ?

  • How to capture a log message coming out of node JS spawn ffmpeg command

    17 janvier 2014, par keenan

    I am trying to find the silent parts of an audio recording. This command does exactly what I want on my local machine.

    ffmpeg -i http://twf-audio.s3.amazonaws.com/uploads/DBC50460-9A5C-4174-9885-07337A582D58_1377839443598_tell.m4a -af silencedetect=n=-40dB:d=0.2 -f null -

    It sends a bunch of messages to the command line including these last three which are the lines of data that I need. (for reference : ffmpeg silencedetect docs)

    [silencedetect @ 0x7feea040cf20] silence_start : 0.0321995

    [silencedetect @ 0x7feea040cf20] silence_end : 0.975238 | silence_duration : 0.943039

    [silencedetect @ 0x7feea040cf20] silence_start : 1.47184

    I cannot figure out how to get that message out. Here is the nodejs code that is running. The only event that is triggered is the 'exit'. I thought that "pipe:1" sends output to stdout but that does not do anything.

    var ffmpeg = spawn('ffmpeg', ['-i',filename,'-af','silencedetect=n=-40dB:d=0.2', '-f', 'null','-y', 'pipe:1' ]);
    

    
ffmpeg.on('message', function(data) {
    
    console.log('ffmpeg2 PARENT got message:', JSON.stringify(data));
    
});
    

    
ffmpeg.stdout.on('data', function(data) {
    
    console.log('ffmpeg stdout data = '+JSON.stringify(data) );
    
});
    

    
ffmpeg.on('exit', function (code, signal) {
    
  console.log('child process exited with code:' + code + ' signal:' + signal);
    
});

  • error in ffmpeg when sending image from pipe via php

    12 décembre 2013, par Abdul Ali

    used the following tutorial to send an uploaded image to ffmpeg from php via pipe.

    Image pipe from php to ffmpeg

    however it raises an eror saying that the pipe has invalid data in it.

    pipe:: Invalid data found when processing input

    following is the php code for uploading an image file

    $tempPath = $_FILES['vdofile']['tmp_name'];
    

    
print_r($tempPath);
    

    
$descriptorspec = array(
    
    0 => array("pipe", "r"), // stdin is a pipe that the child will read from
    
    1 => array("pipe", "w"), // stdout is a pipe that the child will write to
    
    2 => array("file", "error-output.txt", "a") // stderr is a file to write to
    
    );
    

    
$img = imagecreatefromjpeg($tempPath);
    

    
 $proc = proc_open("ffmpeg image2pipe -i - -y image.jpg", $descriptorspec, $pipes);
    

    
 if (is_resource($proc)) {     
    
     /*
    
      * $pipes[0] = write something to command being run
    
      * $pipes[1] = read something from command
    
      * $pipes[2] = error from command 
    
      */
    
       fwrite($pipes[0], $_FILES['vdofile']['tmp_name']);
    
       fclose($pipes[0]);
    
 }
    
 proc_close($proc);
    
?>

    and simple html uploading code is as follows :

     <form action="upload.php" method="post" enctype="multipart/form-data">
    
        <input type="file" />
    

    
        <input type="submit" value="Upload" />
    
    </form>

    the error file generated is as follows :
