Opus and Daala: State of the Art Royalty-free Codecs

Opus is a state-of-the-art royalty-free lossy audio codec convering more applications than any other single audio codec— from low latency VoIP to high fidelity music storage. After five years of open development, including contributions from Xiph.Org, Skype/Microsoft, Mozilla, Broadcom, and many individual developers, Opus was standardized in 2012 by the IETF in RFC 6716 and has since been deployed to hundreds of millions of computers and devices.


Daala is a new open effort to build a state-of-the-art video codec targeting compression performance beyond HEVC and VP9. Leveraging the experience we had with Opus we are building a new technical framework for video coding the ground up to avoid patent thickets and be royalty free: By breaking from the common design pattern of block based transform codecs we avoid many licensing complications and create an opportunity to better resolve some of the weaknesses of existing formats.

Google's VP9 video codec nearly done; YouTube will use it

Google's VP9 video codec nearly done; YouTube will use it | The Machinimatographer | Scoop.it

One of the biggest video sites on the Net will use Google's next-generation video compression technology after it's fully defined on June 17.

 

The VP9 bitstream definition, which describes how video is compressed into a stream of data so it can be transmitted efficiently over a network, has been in beta testing for a week, said Matt Frost, senior business product manager for the WebM Project.

 

Paul Wilkins, a Google codec engineer, detailed the final schedule for the VP9 bitstream definition Thursday in a mailing list post.

 

WebM will be updated to accommodate the new video codec and a new audio codec called Opus, too, said another Google employee, Lou Quillio.
