Daala is the codename for a new video compression technology.
The effort is a collaboration between the Mozilla Foundation, the Xiph.Org Foundation and any other contributors that wish to help.
The goal of the project is to provide a video format that's free to implement, use and distribute, and a reference implementation with technical performance superior to H.265.
Please see the links below or the main page for more information.

Communication
You are encouraged to join the
Weekly Meetings
You are also welcome to attend the public weekly progress meetings by installing and using Mumble.
The address is mf4.xiph.org and the port is 64738 (you can run mumble://mf4.xiph.org:64738 within your browser as a shortcut).
The meetings occur on Tuesdays at 9AM Pacific Time (5PM UTC/GMT).
The meeting agenda used to be available at this Etherpad, the October 13, 2015 meeting is available on Google Docs and, following the migration to Etherpad Lite, the meeting agenda and minutes are now available at this Etherpad.
Other
- Doom9 Forum discussion - generic forum thread regarding Daala
Daala Etherpads - you can request a free account to view these. You should receive access within a few days.Mozilla are transitioning to Etherpad Lite.- Daala Project Status Board - what Daala bits the Mozilla people are working on
Coding
You can get a copy of the latest Daala Source Code from git.xiph.org or GitHub. Please stick to the Coding Style Guide.
- Xiph Code Reviews - there is a proposal on the review process here
- Daala's issues - Issue/bug tracker on Github
- Continuous Integration Tests - these run every time a new commit is made to the Daala git master, to make sure the new code hasn't broken existing functionality.
- OggDaala - definitions for embedding Daala video within an Ogg container.
Demos
- Daala Video Player - an example implementation of a Daala decoder and player, ported to Javascript using Emscripten.
Codec Techniques
- Demo Articles - explanations on certain techniques used in Daala (and other Xiph.Org projects)
- Edge-Directed Interpolation (source code)
- More Edge-Directed Interpolation
- Intra-prediction
- Macroblock Coefficient Zigzag Graph - HTML page generated using tools/draw_zigzags.c from the Daala source code.
- Still Image Screenshots - comparison between Daala's Lapped Transform and Haar methods, and JPEG/x264/x265.
Documents
- Chroma from Luma (CfL)
- Perceptual Vector Quantisation (PVQ) - see also Applying PVQ Outside Daala
- Overlapped Block Motion Compensation (OBMC)
- C API Documentation
- Image Coding Thesis by Yushin Cho
- Maximising Coding Efficiency Through Block Rotation and why it won't work well within Daala

- Daala Technologies Poster
IETF Drafts
- Time-Domain Lapped Transforms (TDLT) - documents the Lapped Transform pre- and post-filters used for block-edge decorrelation
- Perceptual Vector Quantisation (PVQ) -
- Coding Tools - documents Entropy Coding, Integer Transforms and other techniques
- Internet Video Codec (NetVC) Requirements - explains what requirements and use cases Daala is trying to cater for
- Internet Video Codec (NetVC) Testing and Quality Measurement
