Daala video compression
Daala is the code-name for a new video compression technology.
The effort is a collaboration between Mozilla Foundation,
Xiph.Org Foundation and other contributors.
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.
