Its documentation describes the API as targeting MPEG-4 Systems and ISO Base Media File Format style MP4 files, a container lineage derived from Apple's QuickTime file format. ### プロジェクトの歴史 The project originated as part of the mpeg4ip codebase and was separated into its own maintained library because the MP4 container code was useful independently after mpeg4ip support faded. The mp4v2.org revival fork was created after the Google Code-hosted project had been abandoned, with goals including build-system modernization, import of fixes from downstream forks, security fixes, updated API documentation, and support for additional formats. ### 使われ方 MP4v2's practical surface is split between its library and command-line tools. Applications use the library to inspect and mutate MP4 tracks, samples, chapters, artwork, and iTunes-style metadata, while package users get utilities such as mp4art, mp4chaps, mp4file, mp4subtitle, mp4tags, mp4track, and mp4trackdump. It occupies a legacy but still packaged niche beside FFmpeg/libavformat, Bento4, GPAC, and Go-based ISOBMFF libraries: direct programmatic MP4 manipulation with small companion tools. ### ソース - - - - - - ## セキュリティノート narrow executable package without higher-risk signals. - **Geiger リスク:** グリーン / 低 - narrow executable package without higher-risk signals ## ソースデータベース詳細 - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** mp4v2 - **Version Scheme:** 0 - **Revision:** 0 - **Conflicts With:** bento4 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## 他のパッケージマネージャ記録 - Nix - mp4v2: normalized package name match | nixpkgs package indexes: pkgs/by-name/mp/mp4v2/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - MacPorts - mp4v2: normalized package name match | MacPorts ports tree: multimedia/mp4v2/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 ## 関連リンク - [Terminal utility packages](https://pkg.so/ja/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Networking and protocol packages](https://pkg.so/ja/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [Media and graphics packages](https://pkg.so/ja/media-graphics-tools/) - Matched media, image, audio, video, or graphics metadata. - [Homebrew utility packages](https://pkg.so/ja/brew-utility-packages/) - Matched Homebrew package provider. - [libvmaf](https://pkg.so/ja/brew/libvmaf/) - Shares pkgdb curated category or tags: cli, library, media, video. - [ffms2](https://pkg.so/ja/brew/ffms2/) - Shares pkgdb curated category or tags: cli, library, media, video. - [mkvtomp4](https://pkg.so/ja/brew/mkvtomp4/) - Shares pkgdb curated category or tags: cli, media, mp4, video. - [libwebm](https://pkg.so/ja/brew/libwebm/) - Shares pkgdb curated category or tags: cli, library, media, video. - [mp4ff](https://pkg.so/ja/brew/mp4ff/) - Shares pkgdb curated category or tags: cli, media, mp4, video. - [ffmpeg](https://pkg.so/ja/brew/ffmpeg/) - Shares pkgdb curated category or tags: cli, media, video. - [jasper](https://pkg.so/ja/brew/jasper/) - Shares pkgdb curated category or tags: c, cli, library, media. - [gd](https://pkg.so/ja/brew/gd/) - Shares pkgdb curated category or tags: c, cli, library, media. - [ffmpegthumbnailer](https://pkg.so/ja/brew/ffmpegthumbnailer/) - Both packages work with overlapping file formats or content types.
