Internally it is C++, while the public API is pure C, making it linkable from C-compatible applications. FFMS2 has historically tracked FFmpeg and Libav API churn closely. Its changelog records support for recent FFmpeg builds, VapourSynth support in the 2.18 era, API and index improvements across the 2.x releases, removal of old Libav support in 2.40, and a 5.x line that raised minimum FFmpeg requirements. ### 採用の歴史 The package matters most in video scripting and fansubbing-adjacent workflows where Avisynth or VapourSynth scripts need reliable opening, indexing, seeking, VFR handling, Unicode path handling, and access to FFmpeg's broad demuxer and decoder support. Package managers expose the ffmsindex tool and the library/plugin pieces so scripts can build repeatable indexes before frame access. ### 使われ方 End users most visibly use FFMS2 through the Avisynth or VapourSynth source plugin, while developers can link the C API. The ffmsindex executable builds index files so later frame and audio access can be deterministic instead of relying on ad hoc seeking through containers. ### パッケージ好きにとっての重要性 FFMS2 is a dependency-sensitive media package: it wraps FFmpeg, but its value is hiding FFmpeg API complexity from script authors and applications. The changelog's repeated compatibility entries explain why packagers care about aligning FFMS2 releases with the FFmpeg versions in the same repository. ### タイムライン - 2013: FFMS2 2.18 added VapourSynth support. - 2020: FFMS2 2.40 removed old Libav support and refreshed FFmpeg API usage. - 2024: FFMS2 5.0 fixed FFmpeg 6.1 compatibility and made FFmpeg 6.1 the minimum. - 5.1: FFMS2 raised its minimum requirement to FFmpeg 7.1. ### Related projects - FFmpeg is the decoding and demuxing foundation. Avisynth and VapourSynth are the scripting environments where FFMS2's source plugins are most visible. ### 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 -
