 ## Overview
-This package provides integration with **[PHP-FFMpeg](https://github.com/PHP-FFMpeg/PHP-FFMpeg)** and package media content for online streaming such as DASH and HLS. You can also use **[DRM](https://en.wikipedia.org/wiki/Digital_rights_management)** for HLS packaging. There are several options to open a file from clouds and save files to them as well.

 - **[Full Documentation](https://video.aminyazdanpanah.com/)** is available describing all features and components.
 - **[A complete example](https://video.aminyazdanpanah.com/start/example)** is provided. It contains server-side(Transcoding + cloud + progress + web socket) and client-side(progress bar + web socket + player).
 - For using DRM and encryption, I **recommend** trying **[Shaka PHP](https://github.com/aminyazdanpanah/shaka-php)**, which is a great tool for this use case.
