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
You are also welcome to attend the weekly progress meetings 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).
