Daala
Daala is the code-name for a new video compression technology.
The effort is a collaboration between Mozilla Foundation, the Xiph.Org Foundation and any other contributors that wish to help.
The goal of the project is to provide a free-to-implement, -use and -distribute digital media format
and reference implementation with technical performance superior to H.265.
