- Update to version 7.2.0
Framework:
* Added support for `mlt_properties` as a child of
`mlt_properties` including XML (de)serialization:
+ `mlt_property_set_properties()`
+ `mlt_property_get_properties()`
+ `mlt_properties_set_properties()`
+ `mlt_properties_get_properties()`
+ `mlt_properties_get_properties_at)(`
+ `Mlt::Properties::set()`
+ `Mlt::Properties::get_props()`
+ `Mlt::Properties::get_props_at()`
Applications can use this to store structured data in its
own namespace, for example "shotcut:markers". And modules
could use this for hierarchical parameters.
* Fixed crash in `mlt_transition` upon inserting or removing a
track.
* Stopped loading `mlt_profile` until needed in `mlt_chain`
creation.
Modules:
* Added filter `gpstext` that is similar to `dynamictext`
based on data in a GPX file.
* Added speed parameter to `timer` filter.
* Added WebP presets for `avformat` consumer.
* Added a pixelate option to the `opencv_tracker` filter's
`blur` property.
* Fixed `center_bias` of `crop` filter not working with
`use_profile`.
* Fixed some missing RGB `mlt_image_format` renames after
change in v7.0.0. This primarily affected presets and
service metadata.
* Fixed a crash when changing preview scaling in `timeremap`
link.
* Fixes problems due to adding redundant normalize filters
upon loading a producer from XML.
* Ensure filters added by the `loader` producer always come
first in list.
* Fixed a crash using `shape` and `affine` filters together on
`color` producer.
* Fixed a crash when a `vidstab` file fails to open.
* Changed `vidstab` filter to save its file in ASCII text mode.
* Fixed a clang LTO error in the `decklink` module.
* Fixed a video decoding regression on some videos in the
`avformat` producer.
* Fixed a crash in the `audiowaveform` filter.
* Fixed loading a relative filename from XML for `mask_start`
with `shape`.
* Fixed "#filedate#" in `dynamictext` filter when used with
`timeremap` link.
* Fixed `timer` filter's new `speed` property interaction with
`start` delay.
* Fixed a crash with YUYV422 (YUY2) input in `avformat`
producer.
* Fixed data race condition in `timeremap` link.
* Fixed compiling `avformat` module with FFmpeg git beyond
v4.4 with many deprecations removed.
* Fixed alpha channel size calculation in `brightness` filter.
* Restore legacy tracker and the new DaSiam tracker for OpenCV
>= 4.5.3 in the `opencv_tracker` filter.
* Fixed a crash in `opencv_tracker` on `shape_width` = 0.
* Fixed incorrect handling of in and out points and duration
in the `opencv_tracker` filter.
* Fixed the `composite` transition leaking left border of an
image on the right side on uneven width.
* Fixed a problem handling some UTF-8 in thhe `typerwriter`
filter.
Other:
* Added support for the `RELOCATABLE` CMake option for Linux
or BSD build.
