Google has recently finalized a next-generation open-source video codec called VP9, as part of the libvpx repository WebM project (http://www.webmproject.org/). Starting from VP8 released by in 2010 baseline, various enhancements and new tools were added, resulting bit stream VP9. The was with exception essential bug fixes June 2013. Prior to release, however, all technical developments being conducted openly public experimental branch for many months. This paper provides brief overview coding included along performance comparisons other state-of-the-art codecs—namely, H.264/AVC HEVC—on standard test sets. While completely fair comparison is impossible conduct because limitations respective encoder implementations, tests show VP9 be quite competitive mainstream codecs.
