Meta & Google Workshop
Title: Alliance for Open Media Workshop, sponsored by Meta & Google
Abstract: The Alliance for Open Media was formed in 2015 and produced its first specification, AV1, in 2018 with the goal of being a royalty-free video coding standard. We will present an overall status update on the adoption and performance of AV1 as well as progress towards a potential future video coding standard, through sets of new coding tools contributed by AOMedia members. Advances in video quality metrics will also be presented, as well as related topics.

Dr. Ioannis Katsavounidis is part of the Video Infrastructure team, leading technical efforts in improving video quality and quality of experience across all video products at Meta. Before joining Meta, he spent 3.5 years at Netflix, contributing to the development and popularization of VMAF, Netflix’s open-source video quality metric, as well as inventing the Dynamic Optimizer, a shot-based perceptual video quality optimization framework that brought significant bitrate savings across the whole video streaming spectrum. He was a professor for 8 years at the University of Thessaly’s Electrical and Computer Engineering Department in Greece, teaching video compression, signal processing and information theory. He was one of the cofounders of Cidana, a mobile multimedia software company in Shanghai, China. He was the director of software for advanced video codecs at InterVideo, the makers of the popular SW DVD player, WinDVD, in the early 2000’s and he has also worked for 4 years in high-energy experimental Physics in Italy. He is one of the co-chairs for the statistical analysis methods (SAM) and no-reference metrics (NORM) groups at the Video Quality Experts Group (VQEG). He is actively involved within the Alliance for Open Media (AOMedia) as co-chair of the software implementation working group (SWIG). He has over 150 publications, including 50 patents. His research interests lie in video coding, quality of experience, adaptive streaming, and energy efficient HW/SW multimedia processing.
Dr. Ryan Lei is currently working as a video codec specialist and technical lead in the Video Infrastructure Media Algorithm team at Meta. His focus is on algorithms and architecture for cloud based video processing, transcoding, and delivery at large scale for various Meta products. Ryan Lei is also the co-chair of the Alliance for Open Media (AOM) testing subgroup and is actively contributing to the standardization of AV1 and AV2. Before joining Meta, Ryan worked at Intel as a principal engineer and codec architect. He worked on algorithm implementation and architecture definition for multiple generations of hardware based video codecs, such as AVC, VP9, HEVC and AV1. Before joining Intel, Ryan worked at ATI handhelp department, where he implemented embedded software for hardware encoder/decoder in mobile SoCs. Ryan received his Ph.D. in Computer Science from the University of Ottawa. His research interests include image/video processing, compression, adaptive streaming and parallel computing. He has (co-) authored over 50 publications, including 17 patents.
Dr. Debargha Mukherjee received his M.S./Ph.D. degrees in ECE from University of California Santa Barbara in 1999. Since 2010 he has been with Google LLC, where he is currently a Principal Engineer/Director leading next generation video codec research and development efforts. Prior to that he was with Hewlett Packard Laboratories, conducting research on video/image coding and processing. Debargha has made extensive research contributions in the area of image and video compression throughout his career, and was elected to IEEE Fellow for leadership in standard development for video-streaming industry. He has (co-)authored more than 120 papers on various signal processing topics, and holds more than 200 US patents, with many more pending. He currently serves as a Senior Area Editor of the IEEE Trans. on Image Processing, and as a member of the IEEE Visual Signal Processing and CommunicationsTechnical Committee (VSPC-TC).
Dr. Balu Adsumilli is currently the Head of Media Algorithms group at YouTube/Google, leading transcoding infrastructure, audio/video quality, and media innovation at YouTube. Prior to this, he led the Advanced Technology group and the Camera Architecture group at GoPro, and before that, he was Sr. Staff Research Scientist at Citrix Online. He received his masters at the University of Wisconsin Madison, and his PhD at the University of California Santa Barbara. He has co-authored more than 120 papers and 100 granted patents with many more pending. He serves on the board of the Television Academy, on the board of NATAS Technical committee, on the board of Visual Effects Society, on the IEEE MMSP Technical Committee, and on ACM MHV Steering Committee. He is on TPCs and organizing committees for various conferences and workshops, and currently serves as Associate Editor for IEEE Transactions on Multimedia (T-MM). His fields of research include image/video processing, audio and video quality, video compression and transcoding, AR/VR, visual effects, video ML/AI models, and related areas.
