    meta.preset.name).

- Update to version 6.8.0
  * This version improves support for multi-channel audio and
    adds some new manipulation functions to the mlt_animation
    API.
  Framework:
  * Added support for musl C library.
  * Added functions for audio channel layouts:
    + mlt_channel_layout_name()
    + mlt_channel_layout_id()
    + mlt_channel_layout_channels()
    + mlt_channel_layout_default()
  * Added channel_layout property to mlt_consumer.

  * Disabled memory pooling by default and require compile macro
    USE_MLT_POOL to re-enable it.
  * Fixed reliability of keyframed properties serializing
    properly.
  * Fixed parsing non-animated string as an animation.
  * Added more functions to mlt_animation:
    + mlt_animation_key_set_type()
    + mlt_animation_key_set_frame()
    + Mlt::Animation::key_set_type()
    + Mlt::Animation::key_set_frame()
  Modules:
  * Fixed some crashes in qimage producer especially with alpha
    channel.
  * Fixed >2 channel audio output in the SDL consumers.
  * Fixed >2 channel audio output in the rtaudio consumer on
    Windows.
  * Fixed vorbis encoding with FFmpeg v3.4+.
  * qimage and qtext are now higher priority than gtk2 pixbuf
    and pango by the loader producer.
  * Added support for more channel counts to decklink consumer.
  * Added swresample filter based on libswresample from FFmpeg.
    This is now the preferred channel count normalizing filter
    used by the loader producer.
  * Fixed the strange "Undefined constant" and "Unable to parse
    option value" log messages in the the avformat consumer.
  * Fixed GIF and DPX writing in avformat consumer.
  * Reduced the memory usage of the affine transition and
    filters.
  * Fixed a crash in kdenlivetitle producer.
  * Fixed a crash in the rotoscoping filter.
  * Fixed frame rate reported in Matroska and WebM files
    produced by the avformat consumer.
  * Added sdl2_audio consumer.
  * Fixed alpha channel support for more pixel formats in the
    avformat producer.
  * Converted the affine transition to use mlt_rect and
    mlt_animation.
  * Fixed LADSPA plugins with mono channel audio.
  Other:
  * Fixed a melt command line parsing bug when argument supplied
    to -transition.
  * Fixed melt with SDL2 on Windows not using stdio and stderr.
  * Improved speed of the vp9 avformat consumer preset.
