What you'll learn

  • Explore Scanner, a new system for analyzing video data, as well as a wide range of video analysis and processing applications and their workload characteristics

Description

A decade ago, systems like Apache Spark and Hadoop made it possible to process big numerical and textual data workloads on clusters of hundreds of machines. Today, the majority of data in the world is video, and companies like Google and Netflix are starting to develop bespoke in-house solutions for processing this big video data at scale.

Alex Poms and Will Crichton offer an overview of Scanner, the first open source distributed system for building large-scale video processing applications. Scanner is being used at Stanford for analyzing TBs of film with deep learning on GCP and at Facebook for synthesizing VR video on AWS. Alex and Will begin by outlining the space of large-scale video analytics applications, and then dive deep into the specific workload characteristics of these applications and how they differ from traditional big data analytics. You’ll learn how Scanner is designed to address these workloads and discover detailed examples of existing applications written in Scanner that have been scaled out to hundreds of machines in the cloud.
