Architecture and Technology Stack

Core Components

ClipBucket is built on a classic LAMP (Linux, Apache, MySQL, PHP) stack, leveraging PHP for server‑side logic and MySQL for persistent storage. The application follows a Model-View-Controller (MVC) pattern, with the core engine written in PHP classes that abstract database interactions and business logic. Views are generated using a templating engine, which separates presentation from logic and facilitates theme development. Routing is handled by a lightweight dispatcher that maps URLs to controller actions.

Media Processing Pipeline

Uploaded media files undergo a processing pipeline that ensures compatibility and quality. The pipeline includes format detection, transcoding to multiple resolutions, and extraction of keyframes for thumbnail generation. ClipBucket utilizes open-source libraries such as FFmpeg for transcoding and ImageMagick for image manipulation. Users can configure the pipeline through an administrative interface, selecting output formats, bitrates, and thumbnail dimensions. The resulting media files are stored in a dedicated media directory, while metadata about each file is persisted in the database.

Extensibility via Plug‑ins

The plug‑in system of ClipBucket allows developers to add or modify features without altering core code. Plug‑ins are PHP packages that register hooks and filters during initialization. The framework exposes a set of events - such as “onUploadComplete” or “onVideoPlay” - which plug‑ins can listen to. This modularity encourages rapid prototyping of new functionalities like comment systems, social sharing buttons, or custom analytics modules. Themes are treated as a special class of plug‑in that controls the visual presentation of the application.

Key Features
