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.
