Version 7.6.0

This version adds image slice-threading to many filters and full support for full range color. All inputs are normalized to and processed at the range specified by the consumer property color_range that defaults to tv/mpeg (limited).

Framework

• Added Mlt::Animation::next_key() and previous_key() with error checking.
• Fixed the moduledir and mltdatadir variables in the pkg-config file.
• Removed calling setlocale() in mlt_factory_init() (moved to melt option -setlocale).
• Added mlt_properties_copy() and Mlt::Properties::copy().
• Changed some primarily internal property names to consolidate on "consumer." as a prefix convention for all consumer properties copied to mlt_frames.
• Added consumer property deinterlacer to replace deprecated deinterlace_method.
• Fixed full range color from producer to consumer.
• Added mlt_slices_size_slice() helper function.
• Fixed choppy playback due to large values in frame_rate_num or frame_rate_den in mlt_consumer.
• Added performance optimization for a single slice in mlt_slices.

Modules

• Added audiolevelgraph video filter to the qt module.
• Added property segment_gap to the audiospectrum video filter.
• Added segments property to the audiolevelgraph and audiospectrum filters.
• Fixed loading image sequence with extended UTF-8 characters in the name of a folder for the qimage producer.
• Fixed a crash in avformat producer if the rotate property is set after the first frame is fetched.
• Added the invert_mask property to the shape video filter.
• Changed avformat producer to normalize frame rates very close to non-integer broadcast frames 24/1.001, 30/1.001, and 60/1.001.
• Converted the chroma and chroma_hold filters' key property to a proper color type.
• Added slice threading to:
  • avformat producer (with FFmpeg v5)
  • swsscale (with FFmpeg v5)
  • lift_gamma_gain
  • shape
  • charcoal
  • vignette
  • wave
  • threshold
  • tcolor
  • sepia
  • mirror
  • invert
  • grain
  • lines
  • spot_remover
• Improved the speed of the oldfilm filter.
• Added a faster box_blur filter to the core module and deprecated the boxblur filter in the kdenlive module.
• Fixed preview scaling for the avfilter.gblur filter.
• Fixed incorrect text overlap in kdenlivetitle producer.
• Improved audio synchronization in avformat when playing in reverse.
• Added much more service metadata (documentation).
• Fixed full range 10-bit video input in avformat producer.
• Fixed full range color handling in:
  • avformat producer
  • avcolor_space
  • brightness
  • resize
  • luma transition
  • movit.convert
  • charcoal
  • invert
  • shape
• Fixed identifying unsupported colorspaces in avformat producer.
