I am trying to install the ffmpeg extension in WampServer for Windows. I have copied all files in particular folders as described here https://www.jaypan.com/tutorial/installing-ffmpeg-wamp.

But I am getting the following errors in Apache error log and library is not loading in phpinfo()

PHP Warning: PHP Startup: Unable to load dynamic library 'ext/php_ffmpeg.dll' - The specified module could not be found.\r\n in Unknown on line 0
Warning: PHP Startup: Unable to load dynamic library 'ext/php_ffmpeg.dll' - The specified module could not be found. in Unknown on line 0

Why am I getting this error? I tried upgrading PHP version but it has no effect on it.

How can I fix this PHP startup issue?

I have added extension=php_ffmpeg.dll but still showing same error – Sukanya
You've installed the wrong dll for the version of PHP you have installed. It needs to be specific to your version of PHP (i.e. 5.4,5.5,5.6,7.0,7.1,etc) 32-bit, 64-bit, zts or non-zts and finally built with the same VC version. – Augwa

You are getting that error because the path to the dll is wrong. Without looking at your file system we can't provide the correct path. Check the path ext/php_ffmpeg.dll against the path of your other dlls that are loading. It has been awhile since I ran PHP on Windows but you could try something like dependencywalker to find the complete path that is attempting to be loaded. You might also have an issue if you are on a 64bit system (sysWOW64 I think). Also, double check you renamed php_ffmpeg_20050618.dll.
