Roadmap

Upcoming (0.5.0)

• Ongoing: Streamline API and implementation for (conceptual) simplicity and robustness
• Ongoing: Porting code to use updated libraries.
• Nearly complete: New parameter system for adjusting plugin options during runtime
• Nearly complete: New commandline tool (lv-tool) to query, run and test visualizations
• TODO: Revamp plugin interface to more naturally support OOP
• TODO: Improve event handling for plugins
• TODO: Re-implement LV::Bin (VisBin) as LV::Sequence (VisSequence)
• TODO: Complete basic examples of using LV (both C and C++)
• Ongoing: New website

Maintenance (0.4.x)

• Ongoing: Backporting of lv-tool.
• Ongoing: Stability and memory leak fixes.
• Ongoing: Porting code to use updated libraries.

Future

• Beat detection system
• Multi-channel (> 2 channel) audio input
• Comprehensive profiling system
• More test waveforms for input_debug
• Fully DAG pipelines
• Unify actors and morphs
• Scripting capabilities using Lua or JavaScript
• Allow mixing of OpenGL and software-rendered visualisations
• Multi-core CPU+GPU rendering
• Optimisation with better use of vectorised CPU instructions, and better cache friendliness
• GUI for lv-tool
• GUI for visually graphing and configuring pipelines
• Port more plugins (ProjectM, Milkdrop, AVS, etc.)
• Android app
• Libvisual plugins for all major media frameworks

0.5.0

System              Summary         Detail  Author

VisParamCollection 	implement 	A new parameter-type that holds a list of possible-options. (Like menu-entries in a drop-down menu) 	starlon
VisBeat 	        implement       Beat-detection API 	starlon
VisParam 	        refactoring     Parameter boundaries are currently stored within VisUI, this should be placed within VisParam. Introduce new list-type. 	starlon
VisAudio 	fix 	Fix crashes that occur with some alsa-drivers. 	rigid
plugins/input/alsa 	implement 	Implement parameters for better tuning of alsa-options 	rigid
plugins/input/alsa 	fix 	Change "ALSA Buffer Overrun" Message from "critical" to "warning" 	  rigid
VisParam 	implement 	Callbacks for parameter checking 	starlon
plugins/actor/lv_analyzer 	implement 	Implement parameters (bars/scale/color...) 	rigid

0.6.0

The goal of the 0.6.0 release is to give application developers a easier to support framework. Part of the strategy is to make displaying plugins easy and also give application developers a good API to access plugin configuration.

Features / TODO

System 	Summary 	Detail 	Author
VisPipeline 	Implement 	Design and implement a system for maintaining pipelines of visualisation plugins, transformation and morphing.
VisBin 	rewrite 	Reimplement VisBin from scratch and make use of VisPipeline for all it's pipeline management.
VisMem 	mem_copy additions 	Create a mem copy that is rowstride aware.
VisVideo and libvisual-display 	on the fly depth change 	Add support to schedule video depth change requests to the display layer.
VisVideo and libvisual-display 	on the fly prefered FPS set 	Add support to schedule a prefered FPS on the fly and propagate this to the display layer.
VisVideo and libvisual-display 	update by rectangle 	Add support for rectangle updates in
VisVideo and the underlaying display layer.
VisVideo and libvisual-display 	pBuffer support 	Add pBuffer support to libvisual and it's displaying stack so plugins like projectM can use it.
VisVideo and libvisual-display 	GL support 	Research what is missing from our GL support stack.
VisSongInfo 	final touches 	Finish up the VisSongInfo framework and allow clients like amaroK to display cover art overlayed in visualisations.
VisParam and VisUI 	refactoring 	Parameter boundries are currently stored within VisUI, this should be placed within VisParam. Also both systems need some serious love to fight bitrotting.
libvisual-display 	implement / refactor 	Create the library and setup the environment.
libvisual-display 	implement / refactor 	X11 driver.
libvisual-display 	implement / refactor 	X11 fullscreen driver.
libvisual-display 	implement / refactor 	GLX drivers.
libvisual-widgets 	implement 	Qt VisUI driver.
libvisual-widgets 	implement / refactor 	gtk1 VisUI driver.
libvisual-widgets 	implement / refactor 	gtk2 VisUI driver. 

0.8.0

All 	Review 	Do a big overall code review 	Everyone
All 	Review 	Do a big overall API review 	Everyone
VisScript 	New module 	New module for super fast evaluation of mathematical expressions 	 Sepp Wijnands and Dennis Smit
VisMem 	Buffer pools and Object pools to improve the memory model 	Dennis Smit
All 	Optimalization 	Find more hot spots for SIMD optimization, do this as generic as possible 	   Dennis Smit
VisFourier 	Enhancements 	SIMD optimalization 	Dennis Smit
VisFourier 	Enhancements 	2D FFT 	Chong Kai Xiong
All 	Refactoring 	Make a generic macro system that can compile our assembly both with gcc and intel syntax style inline assembly compilers. Also we've observed many blocks of instructions that are everywhere the same, we could create a small meta language of macros to make this nicer
