Title: Challenges in video processing at scale
Lecturer: by Dr. Ioannis Katsavounidis (Meta)
Abstract: Social media enabled video sharing and distribution at massive scale. We will cover the basics of video processing, with emphasis on adaptive bitrate streaming, transcoding pipelines, objective quality metrics and efficiency of video encoders, both in terms of rate-distortion and in terms of energy trade offs The importance of convex hull to characterize and optimize such efficiencies will be presented, together with the Dynamic Optimizer framework that can be used to perform this type of optimizations at individual shot, sequence or corpus levels. We will expand into a low-complexity variant of dynamic optimizer that can be used to solve efficiency problems at scale. Finally, we will offer insights in how modern video coding standards can be designed to offer even higher coding efficiency without necessarily increasing energy requirements.
