This version is a general maintenance release with a bunch of fixes, improvements, and additions.

Framework

• Fixed some data races in mlt_consumer, mlt_deque, and mlt_property.
• Fixed the mlt_events listener incorrect owner argument.
• Added support for the LC_ALL environmant variable on Windows.
• Fixed the argument to mlt_factory_init() not working on Windows.
• Fixed mlt_service_identify() not reliable in some use cases.
• Added some default and copy constructors and assignment operators to mlt++
  • Filter()
  • Filter( const Filter &filter )
  • Filter& operator=( const Filter &filter )
  • Producer( const Producer &producer )
  • Producer& operator=( const Producer &producer )
  • Properties( const Properties &properties )
  • Properties& operator=( const Properties &properties )
  • Service( const Service &service )
  • Service& operator=( const Service &service )
  • Transition()
  • Transition( const Transition &transition )
  • Transition& operator=( const Transition &transition )
• Added mlt_luma_map:
  • mlt_luma_map_init
  • mlt_luma_map_new
  • mlt_luma_map_render
  • mlt_luma_map_from_pgm
  • mlt_luma_map_from_yuv422
• Fixed preset overrides depend on the XML attribute order.
• Fixed serializing an animated property with a new length.

Modules

• Fixed interpolation in rotoscoping filter.
• Fixed crop filter not working with color producer.
• Fixed some data races in the sdl and sdl2 consumers.
• Fixed some data races in the avformat producer.
• Added a movit.flip filter to the opengl module.
• Fixed using filters on frei0r producers.
• Added support for in and out attributes on the "consumer" xml element.
• Fixed using an in point with the multi consumer.
• Fixed avfilter fails if the image size changes.
• Fixed showing superfluous decimals for seconds in the timer filter.
• Stop serializing an invalid producer as an "INVALID" text producer in xml.
• Fixed an access violation crash in wave filter.
• Added the meta.media.color_range property to the avformat producer.
• Fixed full range yuv422p not converted correctly in the avformat producer.
• Fixed the text filter not working with pango.
• Fixed a regression using dynamictext with pango.
• Added a position property to avfilter for filters that need position info.
• Fixed avfilter.subtitles not using the source position.
• Added an analyze property to vidstab filter. When set, analysis only starts and the results file written if true.
• Fixed crash combining affine the affine filter with the shape filter.
• Added interlace detection from AVCodecContext.field_order.
• Changed the avformat producer to not use the rescale.interp frame property. Previously, when interp == nearest, it would relax seeking. Now, seek accuracy is reduced during trick play (rewind or fast forward).
• Fixed sws flags for auto-inserted scalers in avfilter.
• Fixed a double free crash in ladspa filter on channel count mismatch.
• Refactored the composite and luma transitions to use mlt_luma_map.
• Refactored the pgm producer and shape filter to use mlt_luma_map.
• Refactored the lumas module to use mlt_luma_map.
• The lumas module is now disabled by default and must be explicitly enabled.
• Added property animation to the threshold filter.
• Added a cairoblend_mode filter to the frei0r module to affect a frei0r.cairoblend transition used to composite/blend tracks.
• Added support for new vaapi options to the avformat consumer:
  • connection_type: x11 or drm
  • driver
  • kernel_driver
• Fixed the timewarp producer with a colon in the filename.
• Fixed a relative file name with a colon in it in the xml producer.
• Fixed defaulting to album or poster art if there is another video stream.
• Fixed parameter animation in frei0r plugins when using frame threads. This change also enables frame-threading for more plugins.
• Improved the qtblend filter to not process alpha if no transparency.
• Added a background_color property to the qtblend filter.
• Fixed the opencv.tracker incorrect behavior on cut clips.
• Changed opencv.tracker to store absolute frame numbers.
• Fixed incorrect frame offset on render in opencv.tracker.
• Add an alpha_over property to luma transition. This addresses a behavior regression in version 6.14.0.
• Fixed noimagecache not working in the avformat producer.

Other

• Mlt++ now requires C11 compiler support.
• Fixed closing melt SDL2 window from window manager (i.e. close button).
• Added -repository option to the melt command.
• Added unit tests for Mlt::Event.
• Fixed returning image data for Python 3.
• Switch to python3 by default.
• Updated the prores encoding presets to set vendor ID and colr atom.
• Added a CMake build system. This is not yet prefered over the existing configure script and Makefiles and has less flexibility. It is a start and has limited support.
