    Dr. Timothy B. Terriberry has volunteered for the Xiph.Org Foundation---a non-profit organization that develops free, open multimedia protocols and software---since 2002, and has worked for the Mozilla Corporation in various capacities since 2008. In addition to leading Mozilla's efforts to contribute to the Alliance for Open Media, he ran the Daala project that produced a number of the technologies incorporated into AV1, was the lead developer of the Theora video codec, was one of the developers of the Opus audio codec, and has helped maintain most of Xiph's other codecs. Timothy received dual B.S. and M.S. degrees from Virginia Tech in 1999 and 2001, respectively, in both Mathematics and Computer Science, and a Ph.D. in Computer Science from the University of North Carlina at Chapel Hill in 2006.

Abstract

Last year, the Alliance for Open Media released its next-generation video codec AV1. It achieves better compression than proprietary competitors, while its patents can be licensed via a royalty-free, open-source friendly license. With a broad array of industry support including all major browser vendors, many hardware partners, internet streaming video and conferencing providers, we think this is our best chance yet to create a successful video codec that achieves wide deployment. However, agreeing on the standard was just the first step. This talk will discuss the road from specification to production, the current state of AV1 deployment, and our own efforts to write an AV1 encoder in Rust, rav1e. It is intended for a technical audience, but does not require previous signal processing experience.
