Its history is less about mass-market video editing and more about digital preservation: it gives archivists and media engineers a focused way to validate timecode, recording timestamps, DIF structure, and other DV-specific consistency signals. ### プロジェクトの歴史 The upstream changelog records a first official 0.9.0 release on 2009-04-27, based on MediaInfo 0.7.15 beta, with STA error detection, timestamp and timecode reporting, recording date/time detection, gap detection, and start/end flag detection. Version 1.0.0 followed days later on 2009-04-30 with better support for large QuickTime MOV files and NULL-padded DIFs. During 2009 and 2010 the tool quickly grew from a DV stream inspector into both CLI and GUI-oriented software, adding XML output, Final Cut Pro XML output, table views, summaries, and lower memory usage for large files. MediaArea's own product metadata later listed version 1.4.2 dated 2017-09-26 and described the application as a cross-platform multimedia/video tool. ### 採用の歴史 DV Analyzer's adoption sits in the same preservation-tool ecosystem as other MediaArea projects such as MediaInfo, MediaConch, QCTools, DVRescue, and BWF MetaEdit. It is packaged in Homebrew as a command-line tool because preservation pipelines often need repeatable batch checks instead of manual playback. ### 使われ方 Users run the `dvanalyzer` executable against DV essence or DV-in-container files to generate quality-control reports about timecode continuity, recording timestamps, audio/video structure, and other DV-specific errors. It is useful after tape capture, before ingest, or while triaging a collection of legacy DV recordings. ### パッケージ好きにとっての重要性 For package maintainers, DV Analyzer is notable because it preserves a very specific media-forensics niche rather than a broad playback or transcoding feature set. It is also a small example of the MediaArea pattern: wrap deep container/bitstream knowledge in a repeatable CLI that preservation shops can compose with other tools. ### タイムライン - 2009-04-27: First official 0.9.0 release, based on MediaInfo 0.7.15 beta. - 2009-04-30: Version 1.0.0 added large MOV support and improved NULL-padded DIF handling. - 2009-09-01: Version 1.3.0 adapted the source for both CLI and GUI use and added XML output. - 2010-05-02: Version 1.4.0 reduced memory use and fixed PAL timecode math issues. - 2017-09-26: MediaArea product metadata lists DV Analyzer 1.4.2. ### Related projects - DV Analyzer is part of the broader MediaArea preservation family, alongside MediaInfo for general media metadata, MediaConch for conformance checking, QCTools for audiovisual quality analysis, and DVRescue for DV tape-rescue workflows. ### 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 ## Combined YAML source View the package source record on GitHub.
