It deliberately ships code, not title keys or device certificates, which is central to how distributions package it. ### プロジェクトの歴史 VideoLAN presents libaacs as a research project for understanding AACS through an open-source library, developed mainly by an international group of Doom9 developers. The project sits near libbluray in the VideoLAN media stack, filling the AACS layer needed by players and tools. ### 採用の歴史 The library was adopted by Unix media stacks because VLC, FFmpeg-adjacent workflows, and Blu-ray playback tools needed a packaged AACS implementation. Its no-keys policy made it easier for repositories to carry the library while leaving key databases and certificates outside the package. ### 使われ方 Users normally install libaacs as a runtime support library for Blu-ray playback or diagnostics, while packagers expose aacs_info for inspection. Encrypted-disc playback still depends on separately supplied legal keys or certificates. ### パッケージ好きにとっての重要性 libaacs is a classic packaging boundary case: the code is useful and free, but the practical playback story depends on data the project intentionally does not distribute. ### タイムライン - 2010s: VideoLAN hosted libaacs as an open implementation of AACS and linked it from the VideoLAN projects list. - 2020-07-23: VideoLAN published the 0.11.0 source tarball. - 2022-02-27: VideoLAN published the 0.11.1 source tarball. ### Related projects - Related projects include VLC, libbluray, libbdplus, Doom9 community research, and the AACS specification maintained by AACS LA. ### ソース - - - - ## セキュリティノート library-like package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - library-like package without higher-risk signals ## 他のパッケージマネージャ記録 - Debian apt - libaacs-bin - 0.11.1-4+b1: normalized package name match | Debian stable package indexes: libaacs-bin from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | free-and-libre implementation of AACS (tools) | https://www.videolan.org/developers/libaacs.html - Debian apt - libaacs-dev - 0.11.1-4+b1: normalized package name match | Debian stable package indexes: libaacs-dev from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | free-and-libre implementation of AACS (development files) | https://www.videolan.org/developers/libaacs.html - Debian apt - libaacs0 - 0.11.1-4+b1: normalized package name match | Debian stable package indexes: libaacs0 from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | free-and-libre implementation of AACS | https://www.videolan.org/developers/libaacs.html - Nix - libaacs: normalized package name match | nixpkgs package indexes: pkgs/by-name/li/libaacs/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - Ubuntu apt - libaacs-dev - 0.11.1-2build1: normalized package name match | Ubuntu 24.04 LTS package indexes: libaacs-dev from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | free-and-libre implementation of AACS (development files) | https://www.videolan.org/developers/libaacs.html - Ubuntu apt - libaacs0 - 0.11.1-2build1: normalized package name match | Ubuntu 24.04 LTS package indexes: libaacs0 from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | free-and-libre implementation of AACS | https://www.videolan.org/developers/libaacs.html - apk - libaacs - 0.11.1-r1: normalized package name match | Alpine Linux edge package indexes: libaacs from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | libaacs is a research project to implement the Advanced Access Content System specification | https://www.videolan.org/developers/libaacs.html - apk - libaacs-dev - 0.11.1-r1: normalized package name match | Alpine Linux edge package indexes: libaacs-dev from https://dl-cdn.alpinelinux.org/alpine/edge/community/x86_64/APKINDEX.tar.gz | libaacs is a research project to implement the Advanced Access Content System specification (development files) | https://www.videolan.org/developers/libaacs.html - pacman - libaacs - 0.11.1-4: normalized package name match | Arch Linux sync databases: libaacs from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | Advanced Access Content System | https://www.videolan.org/developers/libaacs.html - MacPorts - libaacs: normalized package name match | MacPorts ports tree: multimedia/libaacs/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
