• ffprobe Fastest way to read video packets

  12 novembre 2018, par secondplace

  I’ve been using ffprobe to read packets from video streams for analysis. However it’s painfully slow. A 30min 720p video takes roughly 8min to read.
  I’m using the following command at the moment :

  ffprobe.exe -i video.mp4 -show_entries packet=size,pts_time,flags,duration_time

  This gives me the following information for every packet :

  [PACKET]
  
  pts_time=1981.392000
  
  duration_time=0.032000
  
  size=1536
  
  flags=K_
  
  [/PACKET]

  I did read a fair bit in the documentation but it looks like this is just it or is there a way to make this faster ?

  Or would there be any alternative CLI tool to get the above information from a video faster ?

• Evolution #3821 : [sécurité - cookie] possibilité de gérer l’attribut "secure" du cookie spip sess...

  19 novembre 2018, par Absurde Photon

  Bien lire "javascript" au lieu de "java" dans mon message ci-dessus.

  Je n’avais pas assez cherché, je viens de me rendre compte que l’attribut httponly est bien mis sur le cookie de session, donc tout va bien de ce côté.

  Reste l’attribut "secure" dans ce cas, qui est une recommandation OWASP depuis un bon moment : https://www.owasp.org/index.php/Testing_for_cookies_attributes_(OTG-SESS-002)

  Pour ce qui est de l’attribut domain, c’est déjà implémenté dans Spip. Il n’en manque donc plus qu’un pour être complet, "secure" !

  The function in the model :

  public function setUrlAttribute($url){
  
  
  
          $this->attributes['url'] = 'old/'.Carbon::now()->second.$url->getClientOriginalName();
  
          $name = Carbon::now()->second.$url->getClientOriginalName();
  
          \Storage::disk('local')->put($name, \File::get($url));
  
  
  
          $file = pathinfo($name,PATHINFO_FILENAME); 
  
          $extension = pathinfo($name,PATHINFO_EXTENSION);
  
  
  
          $ffmpeg = \FFMpeg\FFMpeg::create([
  
              'ffmpeg.binaries'  => '/usr/bin/ffmpeg.exe',
  
              'ffprobe.binaries' => '/usr/bin/ffprobe.exe',
  
              'timeout'          => 0, // The timeout for the underlying process
  
              'ffmpeg.threads'   => 12,   // The number of threads that FFMpeg should use
  
  
  
          ]);
  
          $video = $ffmpeg->open($url);
  
          $format = new FFMpeg\Format\Video\X264('libmp3lame', 'libx264');
  
          $format->on('progress', function ($video, $format, $percentage) {
  
              echo "$percentage % transcoded";
  
          });
  
          $format
  
          -> setKiloBitrate(1000)
  
          -> setAudioChannels(2)
  
          -> setAudioKiloBitrate(256);
  
  
  
          $video
  
          ->save($format, 'files/convert/'.$file.'.mp4');
  
          $this->attributes['url'] = $file.'.mp4';
  
      }
