• Error in configuring ffmpeg in Windows 8 , 5.3 PHP

  28 novembre 2014, par hitesh

  I am trying to configure ffmpeg using this tutorial -
  http://myownhomeserver.com/2012/12/how-to-install-ffmpeg-php-php-5-4-on-windows-8-xampp-1-8-1/
  but after I had done initial configuration, it is throwing error.

  I copied php_ffmpeg.dll in ext folder also added it in php.ini file extension=php_ffmpeg.dll
  copied other files to system32 folder. but it is throwing error while restarting apache. it is throwing below errow

  ---------------------------
  
  httpd.exe - System Error
  
  ---------------------------
  
  The program can't start because avcodec-52.dll is missing from your computer. Try reinstalling the program to fix this problem. 
  
  ---------------------------
  
  OK   
  
  ---------------------------

  I can see that above tutorial was for PHP 5.4 and above so I found this tutorial http://myownhomeserver.com/2012/02/how-to-install-ffmpeg-php-for-windows-apache-http-server/

  this is for PHP 5.3 but still it seems to show same error for me

  I cant understand what went wrong can some help me please.

  But, the problem is i don’t want to save the video, I just want to have live video streaming.

  link : https://trac.ffmpeg.org/wiki/StreamingGuide, provide the command for live video streaming, but it want work, the webcem gets started, but live video streaming is not displayed on screen.

  so, can any one help me out to get right "FFMPEG" command or even any TCL script, to get the live video streaming displayed on on my windows 7.
