An Overview of new Video Coding Tools under consideration for VP10 - the successor to VP9

摘要

Google started an open-source project, entitled the WebM Project, in 2010 to develop royalty-free video codecs for the web. The present generation codec developed in the WebM project - called VP9 - was finalized in mid-2013 and is currently being served extensively by YouTube, resulting in billions of views per day. Even though adoption of VP9 outside Google is still in its infancy, the WebM project has already embarked on an ambitious project to develop a next edition codec VP10 that achieves at least a generational bit-rate reduction over the current generation codec VP9. Although the project is still in early stages, a set of new experimental coding tools have already been added to baseline VP9 to achieve modest coding gains over a large enough test set. This paper provides a technical overview of these coding tools.
