Daala Planning
This is an overview of the Daala project roadmap.
Information on this page is highly subject to update and change.
Please help reach out to us if you are interested in contributing to the project. We would love your help!
Plans for 2014
See
this etherpad
for details. Most information has moved there. See also the
weekly meeting minutes
on
Daala
for current efforts.
Plans for September, 2013 to March, 2014
Improve existing techniques
Examining and significantly modifying some of the basic coding tools within Daala to improve efficiency and quality:
1) Lapped Transforms
Monty's LT demo
Time-Domain Lapped Transforms
wiki page
2) Frequency Domain Intra-prediction
Monty's Intra-prediction demo
Intra-prediction
wiki page
3) Time/Frequency resolution switching
Monty's TF switching demo
4) Chroma from Luma (CfL)
Monty's CfL demo
5) Motion Compensation tools
Research new techniques
Investigate the following to see if they should be adopted into Daala:
1) Edge-directed Interpolation
smarter's EDI demo in Javascript
2) Multi-frame Motion Compensation
Testing tools
1) Experiment with command-line encode/decode/performance tools
Help people try the codec
Self-testing
Improvement metrics for casual contributors to verify changes
2) Prototype RTP in GIPS/webrtc.org/browser code
3) Prototype HTTP streaming.
Plans for March, 2014 to September, 2014
From March, 2014 to June, 2014: Tuning the various coding tools and components of Daala (assumes investigation and major modifications of the basic coding tools are completed)
By September, 2014: Be able to show significant quality improvements compared to Daala's performance today (September, 2013).
Plans for 2015
Schedule by task
Schedule by person
Progress and Planning Tools
Every week a
Mumble meeting
will occur to discuss current development.
Every month the team will create a detailed task list of what they plan to do for that month.
Every 6-8 weeks the team will report on what they have accomplished.

September 2015
Videolan Dev Days
took place. There are videos on
arewecompressedyet.com
got a new images tab for comparing images between different Daala builds
