My first technical writing regarding the new AV1 codec is up at Xiph.Org. We've been working on AV1, heads-down, for a long time and my writing took a hiatus for almost that entire period. Now that it's out, it's time to continue the technology pages that I started with Daala.
"AV1 is a new general-purpose video codec developed by the Alliance for Open Media. The alliance began development of this new codec using Google's VPX codecs, Cisco's Thor codec, and Mozilla's/Xiph.Org's Daala codec as starting point. AV1 leapfrogs the performance of VP9 and HEVC, making it a next-next-generation codec. The AV1 format is and will always be royalty-free with a permissive FOSS license."
