TL;DR: Daala as discussed by the authors is a new royalty-free video codec that attempts to compete with state-of-the-art royalty-bearing codecs by using technology that is as different as possible from traditional approaches to achieve this.
Abstract: Daala is a new royalty-free video codec that attempts to compete with state-of-the-art royalty-bearing codecs. To do so, it must achieve good compression while avoiding all of their patented techniques. We use technology that is as different as possible from traditional approaches to achieve this. This paper describes the technology behind Daala and discusses where it fits in the newly created AV1 codec from the Alliance for Open Media. We show that Daala is approaching the performance level of more mature, state-of-the art video codecs and can contribute to improving AV1.

TL;DR: This work explores using Daala's keyframe format for still picture coding and shows how it has improved over the past year.
Abstract: Daala is a new royalty-free video codec based on perceptually-driven coding techniques. We explore using its keyframe format for still picture coding and show how it has improved over the past year. We believe the technology used in Daala could be the basis of an excellent, royalty-free image format.

TL;DR: The Daala project is a royalty-free video codec that attempts to compete with the best patent-encumbered codecs, and which compares favorably with HEVC on still images, and is on a path to do so for video as well.
Abstract: The Daala project is a royalty-free video codec that attempts to compete with the best patent-encumbered codecs. Part of our strategy is to replace core tools of traditional video codecs with alternative approaches, many of them designed to take perceptual aspects into account, rather than optimizing for simple metrics like PSNR. This paper documents some of our experiences with these tools, which ones worked and which did not, and what we’ve learned from them. The result is a codec which compares favorably with HEVC on still images, and is on a path to do so for video as well.

28 Aug 2017TL;DR: In this paper, the authors provide an overview of high efficiency video coding (HEVC) and all its extensions and profiles, and present nearly 300 projects and problems included, and about 400 references related to HEVC alone.
Abstract: High Efficiency Video Coding and Other Emerging Standards provides an overview of high efficiency video coding (HEVC) and all its extensions and profiles. There are nearly 300 projects and problems included, and about 400 references related to HEVC alone. Next generation video coding (NGVC) beyond HEVC is also described. Other video coding standards such as AVS2, DAALA, THOR, VP9 (Google), DIRAC, VC1, and AV1 are addressed, and image coding standards such as JPEG, JPEG-LS, JPEG2000, JPEG XR, JPEG XS, JPEG XT and JPEG-Pleno are also listed. Understanding of these standards and their implementation is facilitated by overview papers, standards documents, reference software, software manuals, test sequences, source codes, tutorials, keynote speakers, panel discussions, reflector and ftp/web sites – all in the public domain. Access to these categories is also provided.
