• Merge video with ffmpeg

  17 mars 2017, par Björn

  I have tried this command :
  ffmpeg -i 'concat:10.mov|11.mov' -codec copy out.mov
  The output file out.mov only shows whats in the first movie (10.mov).

  Been googling for several hours and tried lots of things but nothing works. I want this done without re-encoding the files. Just merge with the same codec

• Fix a .WAV header

  28 décembre 2018, par Mattia Mura

  A Ransomware crypted all my files a little time ago, I started studying a way to come over that and I discovered that the ransomware only changes the code of each files up until Offset no.100000. This helped me recovering many of my files just copying and pasting those code lines on the corrupted files from other files with a similiar .ext that werent’t damaged. It has been easy with huge video files and also with some audio files like .3gp or .mp3, but I’m having big issues with a .wav file of 152 MB containing some important audio from an interview.

  I am using HxD to manipulate the code and ffmpeg to fix some of the parts of my files after this copy/paste process. I’ve already tried to fix everything with vlc but it gave me no results

  HERE is the beginning of the file, that doesn’t have any ordinary .wav header anymore because of the encryption.

  And HERE you can see the difference between offset FFFF0 and 100000, to give you a clearer idea.

  Basically I should change the code of the file up until the Offset number 100000, or anyway I should make it work despite those crypted lines. Do you know any way to solve this issue ? Thanks a lot and be patient, is my first question here !

• Anomalie #4516 (Nouveau) : Fatal error en php 8.0

  9 juillet 2020, par Franck D

  Hello, :)

  Windows 10 (1909)
  Firefox 78.0.2
  Easyphp
  Apache 2.4.43 x64
  PHP 8.0.0 alpha1 x64
  MySQL 8.0.20 x64
  PhpMyAdmin 5.0.2

  memory_limit 512M
  post_max_size 130M
  upload_max_filesize 64M
  max_execution_time 300
  max_input_time -1

  Comme php 8.0 sort le 26 novembre, https://wiki.php.net/todo/php80 et que spip 3.4 ne sortira sans doute pas avant 2022... Je commence à faire des tests avec php 8 (plus c’est tôt mieux c’est) histoire de voir si cela posera de gros problèmes avec spip 3.3 !

  Si je lance spip_loader version 3.0.9, j’ai une page blanche avec :
  Fatal error : Uncaught Error : Call to undefined function get_magic_quotes_gpc() in C :\Program Files (x86)\EasyPHP-Devserver-17\eds-www\test2\config\ecran_securite.php:350 Stack trace : #0 C :\Program Files (x86)\EasyPHP-Devserver-17\eds-www\test2\ecrire\inc_version.php(130) : include() #1 C :\Program Files (x86)\EasyPHP-Devserver-17\eds-www\test2\spip.php(17) : include_once(’C :\Program File...’) #2 C :\Program Files (x86)\EasyPHP-Devserver-17\eds-www\test2\index.php(3) : include(’C :\Program File...’) #3 main thrown in C :\Program Files (x86)\EasyPHP-Devserver-17\eds-www\test2\config\ecran_securite.php on line 350

  Je monte la priorité à "haut" pour voir, si cela ne serait pas possible pour spip 3.3.0, mais c’est discutable...
