Yii2 advanced App , PHP extension error - ffmpeg.so


I have a shared web hosting server and running a yii2 basic app for long time without any issue.

Now i have developed a new Yii2 advanced App which works good in localhost (WAMP).

When i uploaded the new app to the same server i got the following error.

PHP Startup: Unable to load dynamic library ‘/usr/local/lib/php/extensions/no-debug-non-zts-20121212/ffmpeg.so’ - /usr/local/lib/php/extensions/no-debug-non-zts-20121212/ffmpeg.so: cannot open shared object file: No such file or directory

Basic App is working well and Advanced app has the above issues on the same server.

What cause the above error? How to fix it?

Plz help.
