mediainfo-d 26.4.2

mediainfo-d

D language bindings for libmediainfo

Upstream reference:

• MediaInfoLib project: MediaArea/MediaInfoLib
• Latest upstream release: 26.01
• D binding entry points live in source/mediainfodll.d and source/mediainfo.d
• Checked-in C/C++ reference copies live in docs/MediaInfo/MediaInfo.h, docs/MediaInfo/MediaInfoList.h, docs/MediaInfo/MediaInfo_Const.h, docs/MediaInfo/MediaInfo_Events.h and docs/MediaInfoDLL/MediaInfoDLL.h

Prerequisites:

• You must have libmediainfo installed on your system
• A working D compiler and Dub.

Usage:

• Add 'mediainfo-d' as a dependancy to your dub project file.
• Please also read the dub documentation for details.

Runtime lifecycle:

• MediaInfo instances register themselves with the singleton loader on construction and release their registration on destruction.
• The shared library is no longer unloaded from individual MediaInfo destructors.
• Call MediaInfoDLL.Cleanup() at program shutdown once no MediaInfo objects are alive.
• If shutdown ordering is uncertain, MediaInfoDLL.Cleanup(true) forces the unload after you have logged the inconsistency yourself.
• The legacy MediaInfoDLL_Load() and MediaInfoDLL_UnLoad() helpers remain available for explicit reference-counted loading.

Local workflow:

• Use scripts/build.sh for library builds.
• Use scripts/test.sh for unit tests and coverage.
• Use scripts/build-docs.sh for documentation builds; generated docs are written to build/docs.
• Test vectors live in test/mediainfo-vectors.json.

import mediainfodll;  /* Import the D binding module into scope */
import mediainfo;   /* Import optionally a more OO layer, WIP */

Todos:

• Port the higher level C++ classes to D

Provenance:

• The bundled C/C++ headers are verbatim reference copies of the upstream MediaInfoLib API surface; they are kept in-repo so ABI drift can be reviewed locally.
• Keep the copies and the D bindings in sync so ABI changes stay visible in the diff.
• The exact upstream source snapshot is not encoded in the files themselves; use the upstream Git tags/releases together with these copies to reconstruct the source level when updating the wrapper.
• Current local wrapper coverage is intentionally narrower than upstream 26.01; the missing pieces are tracked in TODO.md.

Annotation: While working on the dub package, I found some older work at jpf91/MediaInfoD. I adapted and ported some of the code and the example to D2 and the latest libphobos for the dub packaging.
