MLT Release Notes
-----------------
Version 7.2.0
This is the first major maintenance release for the new major version 7
rendering it much more production ready. Plus there are a few nice new features.
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.
Version 7.0.1
This version is just build fixes for the most immediate problems with the
somewhat new but exclusive build system in v7.
* Fixed docker image not working.
* Fixed a system-installed build cannot finds its modules and data.
* Fixed the python installation path for binaries.
* Added support for the `DESTDIR` environment variable when creating melt symlink.
* Increased the build constant for the maximum size of a line of a properties file.
* Fixed the vid.stab metadata install path.
Version 7.0.0
This is a major new version that breaks API to add a major new feature to the
framework: retiming. This is accomplished through new classes `mlt_chain` and
`mlt_link`. And since we are breaking API we decided to clean house by
removing deprecations and switching the build system over entirely to CMake.
For more information see our
[migration guide](https://mltframework.org/docs/v7migration/).
Framework
* Added `mlt_chain` and `Mlt::Chain` classes.
* Added `mlt_link` and `Mlt::Link` classes.
* Added a `link` value to service `type` in the service metadata schema.
* Added a boolean `animation` parameter attribute to the service metadata schema.
* Added `mlt_animation_shift_frame()` and `Mlt::Animation::shift_frames()`.
* Added `mlt_animation_get_string()`.
* Fixed using a stale cached property animation string.
* Added `mlt_image` and `Mlt::Image` classes.
* Remove legacy "height + 1" workaround in image allocation.
* Fixed a crash on setting `timewarp` speed higher than 23x.
* Added `mlt_audio_silence()`.
* Removed `mlt_image_opengl`.
* Replaced variadic arguments in `mlt_events` with new `mlt_event_data` APIs.
* Removed `mlt_geometry` APIs.
* Renamed `mlt_image_rgb24a` as `mlt_image_rgba`.
* Renamed `mlt_image_rgb24` to `mlt_image_rgb`.
* Renamed `mlt_image_glsl` to `mlt_image_movit`.
* Renamed `mlt_image_glsl_texture` to `mlt_image_opengl_texture`.
* Removed virtual function `mlt_frame::get_alpha_mask()`.
* Removed `mlt_frame_get_alpha_mask()`.
* Removed deprecated functions:
- `mlt_sample_calculator`
- `mlt_sample_calculator_to_now`
- `mlt_channel_layout_name`
- `mlt_channel_layout_id`
- `mlt_channel_layout_channels`
- `mlt_channel_layout_default`
- `mlt_slices_init`
- `mlt_slices_close`
- `mlt_slices_run`
- `mlt_playlist_move_region`
- `Mlt::Playlist::move_region`
* Fixed a rounding error calculating display aspect ratio in `mlt_profile_from_producer()`.
Modules
* Added a `timeremap` link to the core module with animatable `map` property.
(Speed can increase or decrease between keyframes including reverse.)
* Added `chain` and `link` XML elements to `xml` module.
* Added "meta.media.has_b_frames" property to `avformat` producer.
* Removed deprecated modules:
- `dv`

* Converted filters to use new `mlt_image` class:
- `brightness`
- `imageconver`
- `mirror`
- `spot_remover`
* Deprecated the `audiowave` filter.
* Added the ability to build the `jackrack` module without JACK to get only
LADSPA producers and filters.
* Deprecated `start` and `end` properties for the following filters:
- `brightness`
- `panner`
- `boxblur`
- `wave`
- `volume`
* Removed deprecated `font` property from `pango` producer.
* Improved album art (attached pic) detection in `avformat` producer.
* Improved the `resample` filter to have less artifacts and use less memory.
Other
* CMake: nearly complete rewrite.
* Removed the old configure bash scripts and Makefiles.
* Added `-chain` and `-link` options to `melt` command line.
Version 6.26.1
This version fixes a major regression in the avformat producer to read from
network URLs.
Version 6.26.0
This is the last planned release of major version 6. Version 7 will be released
soon and introduce some minor API breakage while removing deprecations.
The main new feature in this version is hardware-accellerated decoding!
However, this is a basic implementation: It always returns the uncompressed
video to the CPU memory with no pipelining to filters. Even when coupled with
hardware encoding in the avformat consumer it must transfer the video. Also,

Version 6.2.0 - April 20, 2016
There are no framework changes in this release. The major announcement is the
introduction of support for libavfilter! This is still a work-in-progress.
It is limited to FFmpeg 2.3 and up, and there are a number of filters that
are black-listed because they are known to not integrate with MLT, which is
not a full libav* environment or simple wrapper for it. There are likey
avfilters that are not yet black-listed but might not work because they
have not been completely tested. Also, they do not support MLT's keyframable
property animation nor its frame-threaded parallelism due to architectural
or integration limitations. However, some avfilters are slice-threaded
(internal parallelism), and that works. Finally, libavfilter filtergraph
syntax is not supported either.
All of the supported libavfilters are exposed as MLT filters beginning with
the prefix "avfilter." All of the avfilter parameters are exposed as MLT
properties with the "av." prefix to prevent clashes with MLT properties.
You can run `melt -query filters` to see the new avfilters, and
`melt -query filter=avfilter.rotate`, for example, to view generated
documentation for an individual filter.
Here is a list of notable fixes and enhancements in this release:
* Added support for libavfilter to avformat module.
* Added auto-rotate support to avformat producer.
* Added animated GIF preset for avformat consumer.
* Prevent serializing and deserializing mlt_type property to xml module.
* Fixed relative paths for WebVfx "plain:" resources in xml module.
* Updated libebur128 to v1.1.0 in plus module.
* Added dynamic_loudness filter to plus module.
* Added loudness_meter filter to plus module.
* Qt 5 fixes for kdenlivetitle producer.
* Added gradients and text shadows to kdenlivetitle producer.
* Added support for building rtaudio against external build of lib.
* Upgraded bundled RtAudio to v4.1.2.
* Added status parameters to ladspa producer and filters.
