Media Lovin' Toolkit is an open source multimedia framework, designed and developed for television broadcasting. It provides a toolkit for broadcasters, video editors, media players, transcoders, web streamers and many more types of applications. The functionality of the system is provided via an assortment of ready to use tools, XML authoring components, and an extensible plug-in based API.

By providing a common set of utilities in a single library, it enables developers to easily create video editors as used by Kdenlive and OpenShot. This enables effort to be pooled around a single library for developing this complex piece of software.

Technical overview[edit]

MLT provides a lean API with minimal dependencies (POSIX and C99). The design is modular allowing for the addition of new components and making integration simple with other multimedia libraries and applications. Support is available for the authoring and manipulation of time-based media including playlists, multiple tracks, filters, and transitions using DOM.

High-level language bindings exist for C++, Java, Lua, Perl, PHP, Python, Ruby, and Tcl. Mlt take advantage of Multi-core processor and GPU processing.

MLT has a modular design that supports multiple libraries like FFmpeg and Jack. Through FFmpeg, MLT is able to support nearly all audio and video formats with optimized operations. A comprehensive suite of video and audio effects including image scaling, alpha-compositing, deinterlacing, masking, motion-tracking, audio mixing, audio gain, and wipe transitions.

  • A selection of output targets/profiles including HD
  • An XML authoring schema designed to leverage the full capabilities of the system
  • YAML-based metadata and schema for documentation of modules, their services, and parameters
  • Live IP streaming output via FFmpeg
  • Command line programme: melt


  • Comprehensive Client–server protocol and API for playout scheduling
  • MVCP, based upon work in dv1394d and designed based upon SGI MVCP
