Jingning Han,Bohan Li,Debargha Mukherjee,Ching-Han Chiang,Adrian Grange,Cheng Chen,Hui Su,Sarah Parker,Sai Deng,Urvang Joshi,Yue Chen,Yunqing Wang,Paul Wilkins,Yaowu Xu,James Bankoski +14 more
TL;DR: A technical overview of the AV1 codec design that enables the compression performance gains with considerations for hardware feasibility is provided.
Journal ArticleDOI
An Overview of Coding Tools in AV1: the First Video Codec from the Alliance for Open Media
Yue Chen,Debargha Mukherjee,Jingning Han,Adrian Grange,Yaowu Xu,Sarah Parker,Cheng Chen,Hui Su,Urvang Joshi,Ching-Han Chiang,Yunqing Wang,Paul Wilkins,Jim Bankoski,Luc Trudeau,Nathan E. Egge,Jean-Marc Valin,Thomas Davies,Steinar Midtskogen,Andrey Norkin,Peter de Rivaz,Zoe Liu +20 more
TL;DR: A technical overview of key coding techniques in AV1 is provided and the coding performance gains are validated by video compression tests performed with the libaom AV1 encoder against the libvpx VP9 encoder.
Proceedings ArticleDOI
Novel inter and intra prediction tools under consideration for the emerging AV1 video codec
Urvang Joshi,Debargha Mukherjee,Jingning Han,Yue Chen,Sarah Parker,Hui Su,Angie Chiang,Yaowu Xu,Zoe Liu,Yunqing Wang,Jim Bankoski,Chen Wang,Emil Keyder +12 more
TL;DR: New tools in AV1 are described that improve the prediction of pixel blocks before transforms, quantization and entropy coding are invoked and improve intra, inter and combined inter-intra prediction.
Proceedings ArticleDOI
Machine Learning Accelerated Partition Search for Video Encoding
TL;DR: A multi-scale multi-stage machine learning(ML) based framework to accelerate partition block size search that includes a collection of ML models, each dedicated to make a simple decision for a particular block size at a particular stage during the partitioning rate-distortion optimization(RDO) process.
