Daala: Difference between revisions

From XiphWiki

Latest revision as of 20:24, 25 May 2021

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.

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.

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.
