MLT is a LGPL multimedia framework designed for video editing.

This document provides a quick reference for the minimal configuration, build and installation of MLT.

See the docs/ directory for usage details.

See the website for development details and a contributing guide.

Configuration is triggered by running:

cmake .

More information on usage is found by viewing CMakeLists.txt and the cmake man page.

Once configured, it should be sufficient to run:

cmake --build .

to compile the system. Alternatively, you can run cmake with -G Ninja and use ninja to compile.

To execute the mlt tools without installation, or to test a new version on a system with an already installed mlt version, you should run:

source setenv

NB: This applies to your current shell only and it assumes a bash or regular bourne shell is in use.

The install is triggered by running:

cmake --install .
