mlt-6.10.0

[Bruce Dubbs]

New minor version.

[Bruce Dubbs]

This version fixes bugs and supports serializing animation keyframes with a specified time format (previously only frame number).

Framework

• Reverted mlt_pool change in v6.8.0 pending further testing.
• (USE_MLT_POOL compiler define is now a 0/1 boolean, defaults to 1.)
• Fixed crash regression in v6.8.0 "parsing non-animated string as an animation."
• Added pointer checks to mlt_animation.
• Changed producer cache size heuristic in mlt_multitrack to be more liberal.
• Fixed handling reserved characters in names for YAML in mlt_properties.
• Added clamping to prevent computing negative in and out points to mlt_producer.
• Added functions to serialize animation with a time format:
  • mlt_animation_serialize_cut_tf()
  • mlt_animation_serialize_tf()
  • mlt_property_get_string_tf()
  • mlt_property_get_string_l_tf()
  • mlt_properties_get_value_tf()
  • Mlt::Properties::get(int, mlt_time_format)
  • Mlt::Animation::serialize_cut(mlt_time_format, int, int)
• Added functions to clear a property to mlt_properties:
  • mlt_property_clear()
  • mlt_properties_clear()
  • Mlt::Properties::clear()

Modules

• Fixed enabling sliced pix_fmt conversion in avformat producer.
• Fixed incorrect seek and sync on audio files with discard packets.
• Added support for avcodec_send_frame() API to avformat consumer.
• Fixed compile errors with Libav master.
• Fixed a crash in affine transition.
• Fixed a crash in ladspa filters when consumer frame rate is low (e.g. <= 8).
• Fixed a crash in boxblur filter.
• Added animation support to boxblur hori and vert properties.
• Fixed a crash in movit.convert.
• Fixed incorrect alpha in affine transition blending routine.
• Converted frei0r from deprecated mlt_geometry to mlt_animation API.
• Fixed tilde in text string for pango producer.
• Fixed using more than one channelcopy filter.
• Fixed the mono filter reducing volume level.
• Fixed degraded audio scrubbing in sdl2_audio consumer.
• Converted dynamictext filter to use affine transition for more correct
• alpha compositing and sub-pixel positioning.
• Added time format support for animation keyframes to the xml consumer.
• Added animation support to more affine transition properties:
  • fix_rotate_x
  • fix_rotate_y
  • fix_rotate_z
  • fix_shear_x
  • fix_shear_y
  • fix_shear_z
  • ox
  • oy
  • scale_x
  • scale_y
• Fixed gaps in text when characters overlap in qtext and kdenlive producers.
• Fixed a crash in pixbuf producer with multiple render threads.
• Converted the oldfilm vignette filter from mlt_geometry to mlt_animation.

Other

Numerous updates to mlt-xml.dtd. Categorized many of the encode presets (using meta.preset.name).
