Roadmap

• parallel-processing (in progress, nearly complete)
• Donald Graft's inverse telecine filters (in progress, done but needs a framerate decimation filter)
• add the ability to override avformat's detected top-field-first flag
• add audio balance/pan filter
• add PropertyAnimation (key-frames and interpolation of property values)
• support for multiple consumers or tee-like functionality
• add a framerate normalization filter
• improve support for unlocked DV audio to prevent long-term A/V synchronization problems
• test unit framework:
  • check
  • cutest
  • simplectest
• use motion_est module for scene change detection
• expand motion_est module to track filter masks
• make mlt_position time-oriented
• add support for pipe input to avformat producer (replace usage of ffplay in Kdenlive, will allow application of filters like vectorscope and RGB parade)
• integrate blender (gvfx)
• Bob+Weave for slow motion or double framerate
• add support for top field first output based on a consumer property setting
• rework (loader) normalisation to be a more lazy activity within the framework, possibly through...
• lazy normalization of field order in filter_resize
• expand color spaces, pixel formats, and audio formats (help from gavl or liboil?)
• add field-aware scaler
• add sharpen filter (probably to frei0r)
• pass-through for formats that can support this
• add filter_postproc (or integrate into producer_avformat)
• add filter_audiooffset
• add consumer_jack
• add producer_jack
• add outline support to filter_pango based on kino
• add a gstreamer producer that uses decodebin2
• add gstreamer consumer support? (or implement a gstreamer element gstmlt)
• center crop filter to normalize aspect ratio by cropping instead of padding - think center crop widescreen to 4:3
• AFD support - related to above
• XML deep copy broken (necessary? move to bug tracker)
• allow services to load properties from file specified via special property name ("properties"?)?
• support jack transport (see xjadeo)
• gegl module?
• liboil module? => gavl (or Orc?)
• mencoder filters module?
• avidemux filters module?
• VideoJack (vjack) support?
• add ServerMonkey (ECMAScript, XML DOM, and SVG) producer for SVG animations
• add D-Bus interface (to the server)
• add more traversal and manipulation functions to framework
• add OpenGL output - perhaps to consumer_sdl
• expand YAML Tiny parser to support JSON
• convert melt syntax to YAML Tiny / JSON
• subtitle support
• integrate SoundTouch into producer_framebuffer
• add shared-mime-info loader based on [http://webcvs.freedesktop.org/mime/xdgmime/][xdgmime]]
• add rational type and property type and convert things like aspect ratios and frame rates to use it
• add SNMP support to Melted
• add 'fx cut' to XFER command in Melted
• add support for OnSiteBroadcast's requirements
• UDP Producer

Done

• improve exception handling throughout (ongoing)
• pan/crop filter that can request full resolution image from its producer - affine? rescale? - use to enable Ken Burns effect
• add frame cache
• add Yadif deinterlace filter
• add doxygen code documentation
• add avformat-validate producer alias that serializes as avformat, which does not validate
• integrate NVIDIA VDPAU
• improve seeking on AVCHD
• support embedding SDL window in Qt apps on OS X
• improve support for floating point audio by not requiring so many PCM conversions in the audio processing stack
• convert mlt_frame helper functions into frame virtual functions that services can override
• improve support for RGB by not requiring so many Y'PbPr conversions in the image processing stack
• update documentation on wiki as a result of renaming
• rename things to move away from tackiness and potential trademark violation:
  • MLT = Media Lovin' Toolkit
  • inigo -> melt
  • westley -> xml (.mlt extension)
  • fezzik -> core/loader
  • dvcp -> mvsp (MLT video server protocol)
  • valerie -> libmvsp
  • miracle -> melted (MLT video server daemon)
  • albino -> melted-console
  • humperdink -> melted-client
• debug and troubleshooting functions/tools => mlt_log
• add filter_swscale
• veejay (and related vjing) module? => frei0r
• add a module metadata system to replace services.txt
• consumer_avformat:
  • more properties
  • better properties handling via ffmpeg option parsing
• 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
