next generation video: Introducing Daala

by on June 21, 2013
 

Xiph.org is now leaking out a few details about their new video coded “Daala” that trades the classic DCT representation of frames and video, used in  most other codecs, for a “lapped transform”.

Daala is a new general-purpose video codec currently under development at Xiph.Org. Our performance target is roughly a generation beyond current ‘next-generation’ codecs like VP9 and HEVC, making Daala a next-next-generation effort. As with other Xiph codecs, the Daala format is and will always be royalty-free with a permissive FOSS license.

This is just the first of what I presume will be several pieces detailing Daala’s operation, but it seems to imply the possibility of a lossless-compression mode (similar to PNG), along with some interesting power efficiency and compression features that would be useful.
