The official old download page identifies 2.8.22 as the final stable release from the 2.8 branch, cut from master on 2015-09-05 and released as 2.8.22 on 2023-10-29. The branch is significant because upstream notes it includes changes from ffmpeg-mt and Libav snapshots from August 2015. That places it in the long post-fork reconciliation period when distribution packages and application build scripts often cared about exact FFmpeg/Libav API and ABI behavior. ### 採用の歴史 As a formula, ffmpeg@2.8 serves compatibility rather than new-feature adoption. Homebrew's formula API marks it deprecated but not disabled and builds from the official 2.8.22 tarball, showing it survives as an older release-line package for consumers that still need it. The official 2.8 changelog is dominated by maintenance and security-style fixes in later point releases, including bounds checks, overflow fixes, parser hardening, and demuxer/decoder corrections. That is typical of an old multimedia branch kept alive for downstream stability. ### 使われ方 Users install a versioned FFmpeg formula when an application, script, or build dependency expects 2.8-era command behavior or library versions. The package still provides the familiar FFmpeg tools such as `ffmpeg`, `ffprobe`, `ffplay`, and, in this line, `ffserver`. For direct media conversion, the command-line model is the same as FFmpeg generally: read inputs, choose streams and options, then write outputs. The difference is the release line and linked dependency set, not a separate interface. ### パッケージ好きにとっての重要性 Versioned FFmpeg formulas matter because multimedia stacks are sensitive to codec availability, library ABI versions, and behavior changes. `ffmpeg@2.8` is a compatibility anchor for the Feynman branch rather than the recommended path for new users. The branch tells package historians where old consumers froze: FFmpeg 2.x libraries, 2015 branch point, long-tail point releases, and a Homebrew package kept available even after deprecation. ### タイムライン - 2015: FFmpeg 2.8 branch cut from master on 2015-09-05. - 2015: FFmpeg 2.8 `Feynman` announced about three months after 2.7. - 2023: FFmpeg 2.8.22 released on 2023-10-29 as the final stable 2.8 branch release listed by upstream. - 2026: Homebrew formula API lists ffmpeg@2.8 as deprecated but not disabled, sourced from ffmpeg-2.8.22.tar.xz. ### Related projects - FFmpeg is the upstream project. - ffmpeg-full and ffmpeg are related Homebrew FFmpeg packaging variants. - Libav and ffmpeg-mt are historically relevant because upstream 2.8 release notes mention imported changes from both. ### ソース - - - - - - ## セキュリティノート ffmpeg@2.8 に一致するローカルシークレット処理マニフェストは見つかりませんでした。将来の対応で安定したパッケージ URL を使えるよう、Nucleus パッケージメタデータはここに公開されています。 ## ソースデータベース詳細 -
