nia f42f225ec7 mlt: Update to 6.26.1
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,
there is no automatic software/CPU fallback and no resource management.

Modules
  * Added support for `hwaccel` query string parameter to the `avformat`
    producer. It accepts the following values:
    vaapi (Linux/BSD), cuda (Linux), videotoolbox (macOS), d3d11va (Windows), dxva2 (Windows)
  * Added support for `hwaccel_device` query string parameter to the `avformat`
    producer. This is only used with vaapi (device path) and cuda, d3d11va, or
    dxva (number).
  * Improved the usage of image slice threading in `frei0r`. This only applies
    when `threads`=0 and only works with some frei0r plugins that you must decide
    yourself.
  * Added an ellipse item to `kdenlivetitle` producer.
  * Added support for PNG and GIF as album art in the `avformat` producer.
  * Added BT.2020 color space metadata to the `avformat` producer.
  * Resolved many FFmpeg deprecations in the `avformat` producer making it possible to support AV1 decoding.
  * Added a `strobe` fitler that periodically makes the alpha channel transparent.
  * Added a new `typewriter` text filter (currently only works with the
    kdenlivetitle producer).
  * Improved sound quality for lower pitch shifts in `rbpitch`.
  * Fixed speed of trick play in the `jack`, `rtaudio`, `sdl_audio`, and `sdl2_audio` consumers.
  * Fixed matrix for independent channels in `swresample` filter.
  * Fixed leading zeros for the `timer` filter.
  * Fixed flickering using `affine` with a `luma` transition.
  * Fixed a crash using RGBA images in the `qimage` producer (regression in v6.22.0).
  * Fixed `brightness` filter misbehaves on `alpha` > 1.
  * Fixed writing `flac` format file does not set its duration in the `avformat` consumer.
  * Fixed an infinite loop in `rbpitch` filter.
  * Fixed `ttl` in the `qimage` producer.
  * Fixed building with OpenCV 4.5
  * Fixed artifacts with multiple HTML `qtext` filters and frame threading.
  * Deprecated the `start` and `end` properties on the following (use property
    animation instead):
    - brightness
    - panner
    - boxblur
    - wave
    - volume
  * Deprecated the following services:
    - data_show
    - region
    - transition filter
    - autotrack_rectangle
    - motion_est
    - slowmotion

Other
  * CMake:
    - Fixed building without SWIG.
    - Added many "MOD_..." options to explictly disable modules.
    - Added src/tests and the option `BUILD_TESTING`, which defaults off.
    - All dependency checks moved to top level CMakeLists.txt.
    - Install melt man page.
    - Install oldfilm SVG files.
    - Added src/examples.
    - Install framework/metaschema.yaml.
    - Fixed `plusgpl` datadir.
    - Added all swwig/ languages.
    - Increased C++ standard to C++14.
  * Added an `AV1` encoding preset.
  * Improved documentation of the requirement for C11.
  * The minimum version of FFmpeg is v4.0 and Libav is no longer supported.


Version 6.24.0

  * Trigger a `property-changed` event on `mlt_properties_pass_list`.
  * Fixed using a video transition with a video clip on an audio track.
  * Reduce the amount of service caching to 2X #tracks to reduce memory usage.

Modules
  * Added the `pillar_echo` filter to the plus module.

  * Fixed possible abort or deadlock on recursive pthread mutexes in `avformat` producer.
  * Fixed a crash in `crop` filter with large `center_bias` value when `use_profile` is 1.
  * Fixed a white video frame appearing on threaded rendering in `freeze` filter.
  * Fixed MLT XML DRD to permit empty playlists, which may occur on empty tracks in a multitrack.
  * Fixed initializing QApplication in the `qimage` producer.
  * Fixed interpolation when scaling with the `affine` rect and geomety properties.

Other
  * Fixed CMake build on MSYS2 and Windows Craft.
  * Added the Python binding to the CMake build.
  * Added the `sdl` (v1) module to the CMake build.
  * Removed minrate and maxrate from the `webm` avformat consumer preset.
