Chromium Blog: Celebrating 10 years of WebM and WebRTC

Starting from VP8 in 2010, the WebM Project has delivered up to 50% video bitrate savings with VP9 in 2013 and an additional 30% with AV1 in 2018 – with adoption by YouTube, Facebook, Netflix, Twitch, and more. Equally importantly, the WebM team co-founded the Alliance for Open Media which has freely licensed the IP of over 40 major tech companies in support of open and free codecs.

SVT-AV1 0.8.7 (2021-05-08)

Encoder
  • Feature optimizations: creating new mode decision / encode-decode feature levels allowing better speed / quality trade-off granularity
  • Preset repositioning after adopting new levels
  • Preset 8 achieving similar speed levels to that of x265 medium in the VOD (shot-based encoding) use-case while maintaining quality gains
  • New 1-pass and 2-pass VBR implementation ported from libaom and adapted to the SVT architecture – still a WIP
  • Cleaned up old VBR and CVBR RC code along with the lookahead mechanism associated with them
  • Improvements for TPL algorithm to handle long clips and easy content
  • Added HDR support and color primaries SEI signaling (off by default until integrated with ffmpeg)
  • Memory optimizations, cleaning up data structures to reduce memory usage up to 2× memory reduction in multi-threaded VBR environment
  • Additional AVX2 and AVX512 optimizations
  • Cleaned up unused command line parameters except the config params that are linked to ffmpeg
  • Update user guide and documentation
