New major version. Required for kdenlive.

Version 7.0.1

This version is just build fixes for the most immediate problems with the somewhat new but exclusive build system in v7.

  • Fixed docker image not working.
  • Fixed a system-installed build cannot finds its modules and data.
  • Fixed the python installation path for binaries.
  • Added support for the DESTDIR environment variable when creating melt symlink.
  • Increased the build constant for the maximum size of a line of a properties file.
  • Fixed the vid.stab metadata install path.

Version 7.0.0

This is a major new version that breaks API to add a major new feature to the framework: retiming. This is accomplished through new classes mlt_chain and mlt_link. And since we are breaking API we decided to clean house by removing deprecations and switching the build system over entirely to CMake. For more information see our [migration guide](

  • Added mlt_link and Mlt::Link classes.
  • Added a link value to service type in the service metadata schema.
  • Added a boolean animation parameter attribute to the service metadata schema.
  • Added mlt_animation_shift_frame() and Mlt::Animation::shift_frames().
  • Added mlt_animation_get_string().
  • Fixed using a stale cached property animation string.
  • Added mlt_image and Mlt::Image classes.
  • Remove legacy "height + 1" workaround in image allocation.
