I'm trying to install ffmpeg on xampp (v.1.7.7). I followed all these instructions I found in a forum...
copy ffmpeg.exe somewhere and remember the path for later use
move php_ffmpeg.dll to php extension dir (usually c:\xampp\php\ext)
move all other files to Windows\System32 (except COPYING.GPLv3.txt, readme.txt)
add extension=php_ffmpeg.dll to php.ini (usually c:\xampp\php\php.ini)
restart apache with fingers crossed
If you are using windows 64bit, you will also need to to copy all of those dll files to C:\Windows\SysWOW64 along with C:\Windows\System32.
But my apache service 'runs' and 'stops' when I add the extesion to the php.ini file.
Any help will be well appreciated
