MLT - v7.10.0 released

Nov 1, 2022

The highlight of this version is support for Qt 6.

Fixed some unguarded null pointers.
Added MLT_REPOSITORY_DENY environment variable to skip loading a module (colon delimited list of file names without extension, for example “libmltqt”).
Fixed frame corruption with one frame transition.
Changed so-called test-card frame with audio to show a checkerboard:
- Added mlt_image_fill_checkerboard()
- Added mlt_image_fill_white()
Preserve the producer creation_time property when creating a chain.
Added mlt_image_rgba_opaque().
Fixed getting a property as a timecode or clock value with 24 or 23.98 fps in mlt_property.c.

Added support for Qt 6:
- Added MOD_QT6 and BUILD_TESTS_WITH_QT6 CMake options.
- Allow installing building and installing both Qt 5 & 6 modules.
- Avoid loading both Qt 5 & 6 modules by preferring Qt 5 (use MLT_REPOSITORY_DENY=libmltqt to block Qt 5 and use Qt 6).
- This is limited to the qt module for now and not glaxnimate (still a work-in-progress).
Added support for WebP animation to qimage producer.
Added gps_graphic filter to the qt module.
Added the format property in each producer’s get_frame method to indicate the producer’s default/preferred mlt_image_format to facilitate an optimization in the qtblend transition when the B frame is opaque and has the same aspect ratio.
Added property animation to all audio visualization filters in the qt module.
Improved TGA format detection in qimage filter.
Fixed qtblend transition has incorrect scaling with consumer scaling.
Fixed an case of incorrect alpha scaling in qtblend transition.
Fixed luma transition not updated when resource property changes.
Added the alpha_operation property to the shape filter.
Updated the glaxnimate git submodule to version 0.5.1.
Fixed lines filter in oldfilm regression in v7.6.0.
Added dbpeak property to the audiolevel filter in dB.
Fixed memory leak using some frei0r plugins in conjunction with an affine that animates the rect property.
