• Anomalie #4348 : php 7.4 alpha1

  17 juin 2019

  Pour le time, il y en a au moins un qui vient de prive/objets/info/auteurs.html ;
  

  <span class="CodeRay">[(#BOUTON_ACTION{<span class="tag">&lt;:info_admin_etre_webmestre:></span>,[(#URL_ACTION_AUTEUR{etre_webmestre,[(#REM|time)],#SELF})]})]
  
  </span>

  
  Cela génère time('')

  Un second vient de prive/squelettes/inclure/admin_vider_cache.html ;
  

  <span class="CodeRay">#SET{cache_inhib,#CONFIG{cache_inhib}|sinon{0}|<span class="error">></span>{#REM|time}|oui}
  
  </span>

  En alternative de #REM|time, peut être #EVAL{time()} ?

• Securely using the PHP exec function

  19 janvier 2012, par siberiantiger

  I am writing a PHP script designed to run an executable file (ffmpeg.exe) via the exec() function. The problem is that I have read that using the exec() function can be a security risk and should be avoided if possible. I have been doing some research into how to run the exec() function securely, and the only thing that I keep coming across is to filter the command string with escapeshellcmd or escapeshellarg. What I want to know is if it is possible to further increase security when using the exec() function or if there is a secure alternative to exec(). Any help would be appreciated.

  Here is my code ;

  define('FFMPEG_LIBRARY', 'c:\\ffmpeg7\\ffmpeg\\bin\\ffmpeg ');
  
  $transcode_string = FFMPEG_LIBRARY." -i " . $srcFile . " -acodec libmp3lame -ab 64k -ar 22050 -ac 1 -vcodec libx264 -b:v 250k -r 30 -f flv -y " . $destFile;
  
  $transcode_string = escapeshellcmd($transcode_string);
  
  exec($transcode_string);

  $srcFile is basically the video for transcoding while $destFile is the output file I wish to create.

• sppedUp FFmpegKit overlay Flutter

  17 septembre 2023, par mlika

  I'm using FFmpegKit to overlay text on video :
I'm coding it for macos app, I double checked the CPU usage,it's using only 20%
I have MAC M1 PRO

  


    String drawtextFilter = 'drawtext=fontfile=\'$_fontPath\':'
          'textfile=\'${segments[i].textFilePath}\':'
          'x=(w-text_w)/2:y=(h-text_h)/2:'
          'fontsize=65:fontcolor=white@0.8:' // @0.8 sets the opacity
          'bordercolor=black:borderw=9:'
          'shadowcolor=black:shadowx=5:shadowy=5:' // Adding shadow
          'box=1:boxcolor=black@0.1:boxborderw=20:' // Adding background box
          'fix_bounds=1:'
          'line_spacing=10:'
          'enable=\'between(t,0,${segments[i].duration})\'';
  String command =
          '-i "${segments[i].videoPath}" -vf "$drawtextFilter" -c:v h264_videotoolbox -threads 0 -y "$outputPath"';



  


  The problem is it's taking too long to finish the speed is around 0.6
Is there a solution or alternative as, I'm converting 1hour+ videos and it's taking too much time.
Thanks

  


  

  • I tried compute and Isolate to run multiple ffmpeg but it still very slow
