MLT Release Notes

---

Version 7.30.0

Framework

• Fixed Mlt::Producer::set_creation_time() not exported on i686.
• Fixed Mlt::Properties::set(int64_t) symbol version.
• Fixed mlt_factory_init() on Linux/BSD may fail to initialize when compiled with -DRELOCATABLE.
• Added generic non-drop-frame timecode in mlt_property.c. Previously, it was only done for 30000/1001 and 60000/1001 frame rates, but 24000/1001 is especially important as well.
• Added support for MLT XML embedded in chains. This, along with xml-clip producer handles mismatching frame rate between parent and child producers and facilites time-affecting links on the child.
• Added mlt_image_full_range(const char *color_range) where any of the following strings return true (1): full, jpeg, pc.

Modules

• Added xml-clip producer.
• Fixed link in and out properties arenot serialized in the xml consumer.
• Added hslprimaries and hslrange filters to the plus module.
• Added a gradientmap filter to the plus module.
• Fixed avfilter audio filters with FFmpeg 7.
• Fixed incorrect frame rate for AVCHD (and possibly others) in avformat.
• Fixed window_id property in consumer sdl2 by using SDL_CreateWindowFrom(), especially important for embedding in GTK+ or Qt.
• Fixed text not rendering in transition vqm since Qt 6.
• Added decimals keyword to gpstext filter and move RAW keyword check.
• Fixed time_offset property handling in gpstext filter.
• Fixed reading and writing SRT files with unicode in the path.
• Fixed subtitle_feed filter on producers with an in point > 0.
• Fixed opaque alpha channels become translucent in luma transition.
• Fixed a crash in the mix transition with consumer producer.
• Fixed freeze filter freezing too much.
• Fixed avfilter.fillborders with preview scaling.
• Fixed non-proportional scaling in qtblend transition and filter.
• Fixed avfilter color distortion with mlt_image_rgb and mlt_image_rgba.
• Extended support for colorspace=2020 consumer propeerty and the BT.2020 colorspace in the avformat producer and consumer. This does not imply HDR, which is signaled through a color_trc property.

• Added support for mlt_image_yuv420p10, mlt_image_yuv444p10, and mlt_image_yuv422p16 in avfilter, swscale, and rescale filters. This facilitates using these pixel formats end-to-end when using only FFmpeg producers, certain avfilters, and avformat consumer. This means it is possible to do 10-bit end-to-end on the CPU when being careful to select compatible components and options to avoid conversions. One can pass-through HDR; however, you must set the color_trc and pix_fmt properties on the avformat consumer (see ffmpeg -h full for these values). The avformat consumer automatically converts MLT colorspace (integer value) to FFmpeg's colorspace and color_primaries (unless explicit) options.

Other

• Cleaned up the examples in src/swig.
• Changed the x264-medium preset to a higher quality.
