  7 mai 2019, par Armen Spidermian

  Bonjour,

  Je me suis aperçu de ce dysfonctionnement sous spip 3.2.1
  Le site a été mis en prod et j’ai cru un moment que le probleme venait
  de mon hébergeur
  J’ai donc rapatrié une copie du site sur une machine de dev
  ou nous envisagions de migrer mais le probleme existe toujours.
  Ah oui ma version de php est 5.6.38 chez notre hébergeur et 5.6.40 ,sur
  le serveur de dev.
  Je ne comprends d’autant mons cette eeereur que j’ai un autre spip (3.2.4)
  qui tourne sur cette machine et qui n’a pas ce probleme.
  Je comprends que vous n’ayez pu reproduire cette erreur et donc de la
  traiter
  Mais comme je l’ai dit dans mon ticket je n’ai pas la moindre idée d’ou
  cela peut venir et donc ou chercher,
  peut-être pouvez vous me soumettre quelques pistes ?

  D’avance Merci.

• Why is audio stream extraction slow ? (compared to AviSynth)

  6 mai 2019, par LLL

  I want to extract the audio stream of an avi file as a wav file, it works but it is really slow ( 4-5fps) although I just want to copy the stream.

  Here is the type of stream I want to extract (ffprobe info) :
  Stream #0:1: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 44100 Hz, stereo, s16, 1411 kb/s

  Going through AviSynth does it about 100 times faster, but I would prefer a pure FFmpeg solution. Why such a speed difference ? It looks like FFmpeg is reading and processing through the whole file whereas AviSynth can just extract the data without reading it.

  Example :
  ffmpeg -i file.avi -vn -ac 2 -c:a copy audio.wav
  or
  ffmpeg -i file.avi -map 0:a -ac 2 -c:a copy audio.wav
  both work fine but take time.

  Using an AviSynth script as input :
  ffmpeg -i script.avs -map 0:a -ac 2 -c:a copy audio.wav
  with script.avs containing just :
  AviSource("file.avi")
  does the same but almost instantaneously !

  Any idea why AviSynth is so much faster and if there is a way to get the same speed in FFmpeg ?

  Edit : adding logs
  Using FFmpeg directly :

• FFMPEG PHP enter command lines ?

  3 mai 2019, par Robert

  You will have to excuse me I have been spending the past 2 days reading through old FFMPEG posts for an answer but did little but confuse myself.
  It seems from what I read FFMPEG-PHP wrappers aren’t supported anymore ??? and to be honest they don’t seem like the proper way of learning how to incorporate it with PHP as there is a whole lot more help for command line FFMPEG usage and the FFMPEG-PHP wrapper usage looks nothing like the command line as far as I can tell.

  So I have 2 questions on using ffmpeg with PHP. So we are on the same page I posted a little info below.

  I downloaded FFMPEG static for windows 64bit.
  I then ran (in composer)

        $ composer require php-ffmpeg/php-ffmpeg

  in my vendor folder i have the following path.

      vendor\ffmpeg-20190429-ac551c5-win64-static\bin

  if I open the command prompt in that folder and type FFMPEG I get.

  So I’m pretty sure FFMPEG is installed which was my goal.

  Now on my PHP side here is where I am at, and I’m not sure how this works.

  1ST QUESTION. Do I need to save my $_POST files to the drive before manipulating them ? Or can I use the $file and $filep as is ? I don’t really want to store those files, only the output.

  My SLIM code.

   $app->post('/telestrator', function(Request $request, Response $response) 
  
   {
  
  
  
   $response = array();
  
  
  
   if (isset ($_POST['ID']) && ($_POST['position']) && $_FILES['video'] 
  
   ['error'] === UPLOAD_ERR_OK && $_FILES['image']['error'] === 
  
   UPLOAD_ERR_OK) {
  
  
  
   $file = $_FILES['video']['tmp_name'];
  
   $filep = $_FILES['image']['tmp_name'];
  
   $time = $_POST['position'];
  
   $position = msToTime($time);
  
   $filetime = round(microtime(true) * 1000);
  
   $outputfolder = 'teletemp/';
  
  
  
   $ID = $_POST['ID'];
  
  
  
   $tempvid = $ID . 'tempvid' . 'mp4';
  
   $finalvid = $ID  . $filetime . 'mp4';
  
  
  
  
  
   $ffmpegpath = "public/ffmpeg.exe";
  
  
  
  echo "Starting ffmpeg...\n\n";
  
  echo shell_exec("$ffmpegpath -loop 1 -i $filep -c:v libx264 -t 3 -pix_fmt 
  
  yuv420p \"$outputfolder.\" $tempvid /");
  
   echo shell_exec("$ffmpegpath -i $file -t $position -c copy 
  
  \"$outputfolder\" 
  
   small-1.mp4 -ss $position -codec copy \"$outputfolder\" small-2.mp4 ");
  
   echo shell_exec("$ffmpegpath -i small-1.mp4 -i $tempvid.mp4 -i small- 
  
  2.mp4 \ 
  
   -filter_complex \"[0:v:0][1:v:0][2:v:0]concat=n=3:v=1:a=1[outv]\" \ 
  
   -map \"[outv]\" $finalvid" );
  
   echo "Done.\n";
  
  
  
   $upload = new videouploads();
  
  
  
          $desc = 'telestrated video for ' . $ID . $filetime;
  
          $ID = $_POST['ID'];  
  
  
  
          if ($upload->saveVideoFile($finalvid, getFileExtension($finalvid), 
  
   $desc, $ID)) {
  
              $response['error'] = false;
  
              $response['message'] = 'File Uploaded Successfullly';
  
          }
  
       else {
  
          $response['error'] = true;
  
          $response['message'] = 'Required parameters are not available';
  
      }
  
      echo json_encode($response);
  
    } 
  
   });
  
  
  
   function getFileExtension($file)
  
   {
  
   $path_parts = pathinfo($file);
  
   return $path_parts['extension'];
  
   }
  
  
  
   function msToTime($duration) {
  
   $seconds = floor($duration / 1000);
  
   $minutes = floor($seconds / 60);
  
   $hours = floor($minutes / 60);
  
   $milliseconds = $duration % 1000;
  
   $seconds = $seconds % 60;
  
   $minutes = $minutes % 60;
  
  
  
   $format = '%02u:%02u:%02u.%03u';
  
   $time = sprintf($format, $hours, $minutes, $seconds, $milliseconds);
  
   return rtrim($time, '0');
  
  
  
   }

  so it’s not running here is my postman. How do I get it to actually run the FFMPEG.

   Starting ffmpeg...
  
  
  
   Done.
