• Fixed mask_apply filter with custom transition.
• Added input_chmask & output_chmask properties to mono filter.
• Added channel_mask property to LADSPA/LV2/VST2 filters.
• Added channel_mask to the volume filter.
• Added an outline video filter.
• Fixed a deadlock on image with a % in the name in qimage producer.
• Added scrubbing to the decklink consumer.
• Fixed & not decoded to & in the xml producer.
• Fixed converting BT.709 to BT.2020 in the avformat module.
• Fixed building a ladspa module without JACK as dependency.
• Deprecate a JACK Rack XML file in the jackrack and ladspa modules.
• Added filter qtblend_mode.
• Fixed incorrect alpha channel breaking optimization of qtblend.
• Fixed pixel format gbrap (Ut Video with alpha channel) in the avformat producer.
• Fixed opencv_tracker filter on cut playlist clips.

• Disable the SDL1 module in CMake by default.
• Changed melt now exits with 1 if the producer is invalid.
• Various changes to work with MSVC compiler.

[Bruce Dubbs]

Now version 7.34.1, but the changes do not apply to BLFS: "Fixed compiling with Qt 5."

[Bruce Dubbs]

Now version 7.36.1

[Bruce Dubbs]

Version 7.36.1

• Fixed construcing a new producer with a null profile.
• Fixed constructing a xml-clip profile.

Version 7.36.0

Framework

• Added mlt_image_default_colorspace()
• Added mlt_image_default_trc()
• Added mlt_image_default_primaries()
• Added mlt_color_convert_trc()
• Added the mlt_consumer property mlt_color_trc to drive a new color_transform normalizer filter. This sets the color transfer function to use for image/video effects. It is beneficial and correct to use linear color for any pixel mixing whether for blending or interpolation.
• Removed atexit(mlt_factory_close) in mlt_factory_init(). Close the factory yourself if you feel the need to (not generally needed when exiting a process).
• Prevent possible crash in mlt_service_connect_producer().
• Added mlt_profile_is_valid() and Mlt::Profile::is_valid().
• Fixed crash on invalid profile (CVE-2025-65834) in:
  • mlt_consumer_start()
  • mlt_factory_producer()
  • xml producer

Modules

• Drop support for Qt 5.
• Fixed bad color in luma transition's dissolve (regression in v7.34.0).
• Fixed HLG HDR broken in decklink consumer (regression in v7.34.0).
• Fixed warnings when flushing audio in the avformat consumer.
• Added support for hwaccel=vulkan to the avformat producer.
• Added a color_transform normalizer filter to the core module to convert all image/video producers to and from linear color. It is abstract in the core module and drives the following filters:
  • avfilter.zscale
  • sws_colortransform
  • avfilter.scale
• Added filter sws_colortransform that is more efficient than avfilter.swscale but requires FFmpeg 8.
• Changed the default property values of the null consumer:
  • real_time: -1
  • terminate_on_pause: 1
• Changed the luma and movit.luma transitions to progress linearly with linear color_trc.
• Fixed the alpha channel dropped by the xml-clip producer.
• Added mlt_image_rgba64 format to:
  • avcolor_space filter
  • avdeinterlace filter
  • affine filter and transition
  • audiolevelgraph filter
  • audiospectrum filter
  • audiowaveform filter
  • autofade filter
  • avformat producer and consumers
  • box_blur filter
  • brightness filter
  • pillar_echo filter
  • color producer
  • dropshadow filter
  • dynamictext filter (when used with qtext)
  • frei0r.alpha0ps filter
  • frei0r.alphagrad filter
  • frei0r.alphaspot filter
  • frei0r.bluescreen0r filter
  • frei0r.select0r filter
  • frei0r.transparency filter
  • gpsgraphic filter
  • gpstext filter
  • gradientmap filter
  • hslprimaries filter
  • hslrange filter
  • kdenlivetitle producer
  • lift_gamma_gain filter
  • lightshow filter
  • mask_apply (when used with qtblend)
  • movit.convert filter
  • outline filter
  • qtblend filter and transition
  • qtcrop filter
  • qtext producer
  • shape filter
  • spot_remover filter
  • strobe filter
  • subtitle filter (when used with qtext)
  • swscale filter
  • text filter (when used with qtext)
  • timeremap link
  • timer filter (when used with qtext)
  • vqm transition
• Changed the mask_apply filter default transition to qtblend.
• Removed the maximum for the alpha property on the brightness filter so that you can _increase_ the opacity of an existing alpha channel.
• Fixed background image scaling in the gpsgraphic filter.
• Fix audio artifacts with pcm_s24le in mkv in avformat producer.

Other

• Removed bitrate and quality limits in the vp9 and webm avformat presets.
• Fixed melt on Windows not reading file path/name with extended characters (regression in v7.34.0).
• Fixed building the ruby bindings with Ruby 3.0.
• More fixes for MSVC.
• Removed win32/strptime.c and replaced with Qt functions.
• Stop showing melt usage on error exit.
