Rust AV1 encoder (rav1e) project
Applications of Digital Image Processing XLII, 2019Last 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 and ...

AV1: Implementation, Performance, and Application
SMPTE Motion Imaging Journal, 2020With the finalization of the AVI specification, the Alliance for Open Media (AOM) has set high expectations for it. The prospect of a royalty-free alternative to high efficiency video coding (HEVC) has many supporters in the industry, particularly those seeking a standard for streaming applications that is optimized for over-the-top (OTT) delivery ...

Introducing AV1 Codec-Level Video Steganography
2022Steganography is the ancient art of concealing messages into data. High research interest has grown over the last years, however, techniques in literature are only focused on standard and in some way legacy multimedia formats (e.g., H.264). Moreover, most video steganography techniques are based on concealing data into contents of each frame employing ...

Adaptive interpolation filter scheme in AV1
2017 IEEE International Conference on Image Processing (ICIP), 2017Video codecs heavily depend on sub-pixel level motion compensation to achieve superior compression performance. Interpolation filters with both anti-aliasing and denoising properties play a critical role in producing high quality prediction at sub-pixel positions.

Wavefront Parallel Processing for AV1 Encoder
2018 Picture Coding Symposium (PCS), 2018The emerging AV1 coding standard brings even higher computational complexity than current coding standards, but does not support traditional Wavefront Parallel Processing (WPP) approach due to the lacking of syntax support. In this paper we introduced a novel framework to implement WPP for AV1 encoder that is compatible with current decoder without ...

AV1 In-loop Super-resolution Framework
Applications of Digital Image Processing XLII, 2019The AV1 codec added a new in-loop super-resolution mode that allows a frame to be encoded at a lower resolution, and then super-resolved normatively to the full resolution, before updating the reference buffers. While encoding at lower resolution and super-resolving to a higher resolution is not a new concept, this is the first time such a mode has ...

Machine Learning Accelerated Transform Search For AV1
2019 Picture Coding Symposium (PCS), 2019AV1 is the state-of-the-art open and royalty-free video compression format that achieves significant bitrate savings over previous generation of video codecs. One of AV1’s major improvement over its predecessor VP9 is the support of more diverse and flexible transform size and kernel selection.

Short Video Performance Evaluation of AV1 Coding Tools
2021 Data Compression Conference (DCC), 2021Short videos, ranging from a few seconds to a few minutes, have become popular in many video production. So we need efficient coding tools to compress these videos. AV1 is an emerging open-source and royalty-free video compression format jointly developed and finalized in early 2018 by the Alliance for Open Media.

In-loop Frame Super-resolution in AV1
2019 Picture Coding Symposium (PCS), 2019AV1 is a recently standardized royalty-free video codec from the industry consortium Alliance for Open Media. One of the most innovative coding tools supported in AV1 is an in-loop frame super-resolution mode, that allows an encoder to code any frame at a horizontally reduced spatial resolution by one of several levels, followed by upsampling and super-
