• copy step written on stackoverflow to install FFMPEG on wamp not working

  18 novembre 2016, par user3833682

  I’m working on project for converting youtube videos into mp3 format and found this also to install ffmpeg on wamp server Install FFMPEG on WAMP and try other links also but ffmpeg extension is not installing so I also checked it at phpinfo to confirm its installed or not but not installed and I’ve windows 7 64, wampserver 2.4, apache 2.4.4 and php version is 5.4.12 I don’t know what am I missing, I spent my 6 hours to figure out but extension of ffmpeg is not installed yet please tell me what am I doing wrong ?

  Now after that I’m getting popup message twice when I start wamp server `PHP Startup : Unable to load dynamic library

  c :/wamp/bin/php/php5.4.12/ext/php_ffmpeg.dll’ - %1 is not a valid
  Win32 application.

  

• ffmpeg via shell_exec not working

  25 février 2016, par user1661677

  I’m running the following command in the console without any problems :

  ffmpeg -i /var/www/html/input.mp4 /var/www/html/output.mp3

  But when I run the command in PHP, I get nothing :

  <?php
  
  shell_exec("ffmpeg -i /var/www/html/input.mp4 /var/www/html/output.mp3");
  
  ?>

  Any idea what the problem is here ? I’ve checked my CHMOD permissions, everything looks good. Anything else to check ?

  Thank you,
