Need help to work with videos and FFMPEG
The only advantage these modules is assistance in managing your dependency on FFMPEG and how you want interface it in PHP code.


PHP FFMPEG is a helper module for managing a dependency on the PHP FFmpeg library. If you want to use the PHP FFmpeg library, and require a Drupal module that will ensure your module has FFMPEG available to it, this module will help.
FFmpeg Wrapper is a handful of custom functions that interface with FFMPEG via PHP's passthru() function. If your PHP environment can execute passthru() and you want some basic functions to execute some ffmpeg console commands, this module will help.


Both are API modules that don't provide any other integration with Drupal.
