• Exec through PHP. I cant get the output (stderr) into a file

  22 novembre 2019, par Heybuddy

  When I run exec() through php, I fail to get the output (stderr) into a file.

  I’ve included "2> my_out_put_file.txt" at the end of my command to accomplish this. But when I include this, the command is not executed. However, if I run the command without "2> my_out_put_file.txt" then it works.

  The interesting thing is that the whole command, even with "2> my_out_put_file.txt" at the end of the command works if I run directly via shell/promt, but not when I run it through php / apache.

  Does not work :

  exec("C :/FFmpeg/bin/ffmpeg -i $new_path/$filename_with_ext -f mp4 -vcodec libx264 -preset ultrafast -profile:v main -acodec aac $new_path/$filename.mp4 2> out.txt", $a, $b) ;

  Works :

  exec("C :/FFmpeg/bin/ffmpeg -i $new_path/$filename_with_ext -f mp4 -vcodec libx264 -preset ultrafast -profile:v main -acodec aac $new_path/$filename.mp4", $a, $b) ;

• How to install ffmpeg using xampp

  28 avril 2014, par Paul Ledger

  I am trying to install ffmpeg onto my localhost server. I have followed countless blogs and tutorials online form other people who are stuck with this same problem. I follow everything to the letter.

  1. Unzip the file
  2. Copy php_ffmpeg.exe to ext folder in php
  3. copy the rest to system 32

  As it says however when I do this I get this error when I start apache.

  

  Fair play but it is in the folder

  

  I also get this error as well :

  

  And Again, here it is :
  

  I have added the extention to my php.ini file

  extension=php_ffmpeg.dll

  The first time I go this to work I placed the ffmpeg.exe file onto my local host server and ran commands like this :

  $cmd = "$ffmpegpath -i $input -an -ss $sec -s $size $output";
  
  shell_exec($cmd);

  This works fine on my computer but not on an actual server. Could somebody offer some advice or guidene on where I have one wrong installing the extension or why running the .exe file on a lunix server with shell_exec doesn’t work
