• Anomalie #3689 (Nouveau) : Des messages d’erreurs qui ne semblent pas avoir lieu d’être

  9 février 2016, par Franck Dalot

  Bonjour :-)
  SPIP 3.1.0 [22811]
  Php 5.6.15
  Table en MySQL
  Prefix des table : test12

  Quand je télécharge le squelette "scolaspip" en version 4 http://plugins.spip.net/scolaspip.html via SVP, j’ai systématiquement un message d’erreur qui ne me semble pas avoir lieu d’être (voir copie d’écran erreur 0)
  Si dans .../ecrire/ ?exec=admin_plugin&voir=actif je clique sur "Tout cocher", que je choisi "désinstaller", j’ai systématiquement un autre message (voir copie d’écran erreur 1)

  A savoir que cela fait pareil en SPIP 3.0.21 [22462]

  J’ai fait aussi un test en 3.0.21 avec le squelette "SPIPMine 2.0.1 - dev" http://plugins.spip.net/spipmine.html car il necessite également spipr, j’ai le même message que la copie d’écran 0, par contre, je ne peux pas dire pour l’autre message, car SVP semble avoir un problème quand il y a pas mal de necessite, je suis dans l’obligation de réactualiser la page, mais ce point demanderait confirmation par une autre personne

• Update Database After shell_exec() Using FFMPEG/Laravel

  25 avril 2020, par Mike

  I want to update a database record (MySQL) after the FFMPEG process is complete. Normally I would just call a function just after the FFMPEG command, but I needed to add > /dev/null 2>/dev/null & so I didn't have to wait for the FFMPEG process to complete which would mean the REST call would hang for a LONG time and that would cause bad UX for the front-end.

  



  I'm not sure where to begin with it. My first thought is to make a REST request, but maybe calling the method in Laravel directly would be better.

  



  Can I do a curl call after the FFMPEG command ? Or can I call a PHP method ? Or is there a better way ?

  



  PHP FFMPEG Method

  



  private function transcode($movie)
{
    try {
        $name       = 'master.' . $movie->extension;
        $this->path = storage_path('app/public/movies/') . $movie->id . '/';
        $fps        = $this->getFrameRate($name);
        $width      = $this->getVideoWidth($name);
        $height     = $this->getVideoHeight($name);

        // ffmpeg commands
        $c = $this->buildCommand($width, $height, $fps);

        // ffmpeg -  added '> /dev/null 2>/dev/null &' so it will not wait to finish
        $ffmpeg = shell_exec('ffmpeg -i ' . $this->path . $name . ' -progress ' . $this->path . 'transcode.log' . $c . ' > /dev/null 2>/dev/null &');

        return response()->json(['message' => 'transcode initiated'], 200); 

    }
    catch(\Exception $e)
    {
        return response()->json(['error' => $e->getMessage()], 500);
    }
}


  



  Here is the bash curl post idea

  



  $curl = 'curl --data "param1=value1&param2=value2" http://hostname/transcode/complete';

$ffmpeg = shell_exec('ffmpeg -i ' . $this->path . $name . ' -progress ' . $this->path . 'transcode.log' . $c . '; $curl > /dev/null 2>/dev/null &');


  



  I could be going down the wrong path with the above, but I'm trying to move forward with something.
