MLT Multimedia Framework

What it solves

MLT provides a foundational framework for building multimedia and video editing applications. It simplifies the underlying complexities of processing video and audio, allowing developers to focus on creating editing tools.

How it works

MLT is built as a modular framework that uses CMake for configuration and compilation. It includes a standardized development environment via Dev Containers, which allows developers to work within a consistent, isolated setup. For testing and development, it provides scripts to run tools directly from the build directory without requiring a full system installation.

Who it’s for

This framework is designed for software developers building video editing software who need a robust, open-source multimedia engine to handle media processing tasks.

Highlights

  • Standardized development environment using Dev Containers for VS Code, CLion, and other IDEs.
  • Supports hardware acceleration and physical audio access through configurable container settings.
  • Clean build process that keeps source files separate from generated binaries and object files.
  • Built-in testing support via CTest to verify builds before installation.
  • Flexible installation process that supports standard system-wide deployment.
