VP9 in libvpx achieves bitrate reductions comparable to H.265 (HEVC) without patent fees, though at higher computational cost. The 2023 updates to libvpx have reduced VP9 encoding time by ~20% via improved threading and SIMD optimizations (AVX-512). A Decade of Innovation: The Architectural Legacy and

libvpx is the open-source video codec library developed by Google, widely used for encoding and decoding VP8 and VP9 video streams. While the project was open-sourced in 2010, anniversary milestones for the library often highlight its critical role in the adoption of royalty-free web video standards and its integration into platforms like YouTube and the WebRTC framework.

At the Google I/O conference on , Google announced it would release the VP8 codec—acquired through the $124.6 million purchase of On2 Technologies —as an open-source project under a BSD-style license.
