ToDo

• make mlt_position time-oriented
• producer_avformat:
  • reduce usage of properties improves performance?
  • top_field_first working?
• consumer_avformat:
  • beginning of mpeg2 is high quantisation (need repro case)
• expand color spaces, pixel formats, and audio formats
• rework (fezzik) normalisation to be a more lazy activity within the framework, possibly through...
• convert mlt_frame helper functions into frame virtual functions that services can override
• add a gstreamer producer that uses decodebin
• add gstreamer consumer support?
• add producer_avdevice
• add consumer_avdevice
• add filter_postproc (or integrate into producer_avformat)
• add filter_swscale
• add filter_audiooffset
• add consumer_jack
• add producer_jack
• add outline support to filter_pango based on kino
• add drop shadow filter or drop shadow in pango titler - we might be able to do this today, possibly with minor changes
• pan/crop filter that can request full resolution image from its producer - affine? rescale? - use to enable Ken Burns effect
• multi-output virtual consumer?
• pass-through for formats that can support this
• add animation (key-frames and interpolation of property values)
• add doxygen code documentation
• test unit framework:
  • check
  • cutest
  • simplectest
• westley deep copy broken
• debug and troubleshooting functions/tools
• allow services to load properties from file specified via special property name (properties?)
• support jack transport (see xjadeo)
• lazy normalization of field order in filter_resize
• gegl module?
• liboil module? => gavl
• mencoder filters module?
• avidemux filters module?
• veejay (and related vjing) module? => frei0r and/or forthcoming gavl filters
• VideoJack^? (vjack) support?
• logarith producer and consumer
• Donald Graft's inverse telecine filters
• add ServerMonkey^? (ECMAScript, XML DOM, and SVG) producer for SVG animations
• add D-Bus interface
• support for multiple consumers possibly through a master consumer and some properties conventions to control audio/video output of slave consumers and to control which slave consumer controls timing
• add more traversal and manipulation functions to framework

Done

• add a module metadata system to replace services.txt (in progress)
• consumer_avformat:
  • more properties (in progress)
  • better properties handling via ffmpeg option parsing? (in progress)
• producer_avformat:
  • better seeking on temporally compressed video
  • multi-thread support
  • single avformat context possible? Dropped - does not seem to be required or help performance, and it will create grief if we need distinct audio and video seeking
• consumer_avformat:
  • multi-thread support
• remove MLT_NORMALISATION: interplays with the consumer "profile" property, which is also not extensible. consumer profile does not contain framerate info as normalisation does. affected:
  • mlt_frame default properties
  • mlt_producer default properties
  • mlt_geometry: would require nw and nh params not -1 (ok)
  • vmfx/filter_shape, core/transition_luma, core/transition_composite: location of lumas
  • core/filter_data_show: location of feed properties file
• more consumer profiles (HDV patch)
• bug: frames dropped on transcode using consumer_avformat
• address intel darwin compilation
• cleanup compilation warnings especially in westley and jackrack modules
• move module binaries to libdir/mlt (MLT_REPOSITORY) what about .dat files?
• overhaul plugin registration to not use .dat files and to let apps register services
