x266 – Cutting edge open source code for VVC encoding by MulticoreWare Inc.


SAN JOSE, Calif .– (COMMERCIAL THREAD) – The Joint Video Expert Team (JVET), made up of experts in MPEG video coding from ISO / IEC and VCEG from ITU-T, has achieved a key milestone by completing version 1 of Versatile Video Coding (VVC) standard in July 2020.

VVC was developed with the aim of achieving twice the encoding efficiency of the well-known HEVC standard (Rec. ITU-T H.265 | ISO / IEC 23008-2); that is, averaging about 50% bit rate reduction compared to HEVC for similar subjective video quality, or significantly better visual quality at similar bit rate to HEVC.

MulticoreWare announces the formation of the x266 consortium and the development of open source code for VVC encoding is already underway. Likewise, MulticoreWare’s x265 consortium led the development of open source x265 code for HEVC encoding and has become the most widely used HEVC encoding software.

The application areas of x266 will include encoding of high definition (HD) and ultra high definition (UHD-4K and 8K) video for broadcast, live streaming, over the top video distribution (OTT), broadcast Adaptive Bit Rate (ABR) streaming, video storage and archiving, surveillance, screen content sharing, video conferencing, video games, eSports, immersive media such as 360 ° video, virtual reality (VR) etc.

x266 will be able to encode video with Standard, High Dynamic Range and Wide Color Gamut. It will also offer the user the possibility to find a compromise between coding speed and coding efficiency. The initial release of x266 software will support single-layer encoding of 10-bit video in 4: 2: 0 chroma format. More advanced versions will support multi-layered encoding, video greater than 10-bit depth, and chroma formats greater than 4: 2: 0.

Dr Ajay Luthra, CEO of Picsel Labs, commented: “With efficiency significantly higher than currently deployed encoding standards, VVC will begin to replace them and be the driving force behind the success of next-generation video distribution and storage products. ”

“The x266, an open source VVC codec developed by MulticoreWare, will provide an edge in video compression areas by reducing transmission cost and maintaining quality for streaming companies, video conferencing companies and more. The open source VVC consortium formed by MulticoreWare with leading Tier 1 companies will have a significant impact on the market, ”said Arun Ramanathan, vice president and general manager – Media & AI Analytics.
