Version 7.2.0

This is the first major maintenance release for the new major version 7 rendering it much more production ready. Plus there are a few nice new features.


  • Added support for mlt_properties as a child of mlt_properties including XML (de)serialization:
    • mlt_property_set_properties()
    • mlt_property_get_properties()
    • mlt_properties_set_properties()
    • mlt_properties_get_properties()
    • mlt_properties_get_properties_at)(
    • Mlt::Properties::set()
    • Mlt::Properties::get_props()
    • Mlt::Properties::get_props_at() Applications can use this to store structured data in its own namespace, for example "shotcut:markers". And modules could use this for hierarchical parameters.
  • Fixed crash in mlt_transition upon inserting or removing a track.
  • Stopped loading mlt_profile until needed in mlt_chain creation.


  • Added filter gpstext that is similar to dynamictext based on data in a GPX file.

  • Fixed a crash with YUYV422 (YUY2) input in avformat producer.
  • Fixed data race condition in timeremap link.
  • Fixed compiling avformat module with FFmpeg git beyond v4.4 with many deprecations removed.
  • Fixed alpha channel size calculation in brightness filter.
  • Restore legacy tracker and the new DaSiam tracker for OpenCV >= 4.5.3 in the opencv_tracker filter.
  • Fixed a crash in opencv_tracker on shape_width = 0.
