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.

Framework

• 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.

Modules

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

• Added a pixelate option to the opencv_tracker filter's blur property.
• Fixed center_bias of crop filter not working with use_profile.
• Fixed some missing RGB mlt_image_format renames after change in v7.0.0. This primarily affected presets and service metadata.

• Fixed timer filter's new speed property interaction with start delay.
• 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.
