Fraunhofer HHI describes the standard as the successor to HEVC/H.265 and as targeting roughly 50 percent bit-rate reduction at the same subjective quality across a broad set of media applications. VVenC followed that standardization milestone quickly. Its public GitHub repository was created in September 2020, and its wiki says the initial version was released in September 2020. The project was initiated to provide a publicly available, fast, efficient encoder based on VTM but redesigned with SIMD optimizations, improved search algorithms, multi-threading, and practical encoder features. ### 採用の歴史 Fraunhofer presents VVenC as the encoder half of an open VVC toolchain. Its documentation references a 2021 ACM Multimedia paper on a complete end-to-end open-source VVC toolchain, and the wiki describes encoded bitstreams as decodable by standard-compliant decoders such as VVdeC or VTM and usable in multimedia pipelines. ### 使われ方 Users typically feed raw video into VVenC through the command-line encoder or integrate the encoder library for VVC experiments. The project emphasizes predefined quality/speed presets, frame-level rate control, perceptual optimization, and expert controls for researchers or codec engineers who need to tune compression behavior. ### パッケージ好きにとっての重要性 VVenC is significant because reference encoders prove a standard but are usually too slow for everyday experiments. VVenC gives package users an installable, optimized, BSD-licensed VVC encoder that can generate real bitstreams for testing decoders, muxers, adaptive-streaming workflows, and codec comparisons. ### タイムライン - July 2020: VVC/H.266 was finalized. - September 2020: VVenC's public repository was created and the project wiki identifies the initial release. - October 2020: Early public VVenC releases appeared. - 2021: Fraunhofer-associated papers documented VVenC as an open optimized VVC encoder and part of an end-to-end open-source VVC toolchain. ### Related projects - VVdeC is the companion decoder; VTM is the VVC reference model; FFmpeg and GPAC-style multimedia pipelines are natural downstream integration points for encoded VVC bitstreams. ### ソース - - - - - ## セキュリティノート broad file, network, media, or database tool signal. - **Geiger リスク:** blue / 中 - broad file, network, media, or database tool signal ## 他のパッケージマネージャ記録 - Nix - vvenc: normalized package name match | nixpkgs package indexes: pkgs/by-name/vv/vvenc/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
