Revision as of 12:28, 24 May 2015
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.
Wiki Pages
- Digital Primers - educational videos about audio/video technology
Project Communication
You are encouraged to join the
- #daala IRC channel at freenode.net
- If you don't have an IRC client, you can use Freenode' webchat instead.
- Daala Email List
You are also welcome to attend the 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 can be found at this Etherpad.
