At a glance

The movie library: manages a library of movie items (metadata, thumbnails, video processing) for the browsing surfaces. The reference binary exposes a single meaningful export — CreateMovieFactory — and a notable D3D9-based video processor among its RTTI classes (Movie Maker 2012 still used D3D9 paths for certain video processing, even as the main engine moved to D3D11).

From WLXMovieLibrary.def:

CreateMovieFactory @1
DllCanUnloadNow     DllGetClassObject
DllRegisterServer  DllUnregisterServer

Implementation notes

• CreateMovieFactory is the entry to the library object model; factory behavior is contract-pinned.
• The D3D9 video processor surfaces the older d3d9.lib link (present in the common system libs of the root CMake file) — kept because the original used it.
• Movie browser features in the main app's MediaBrowser talk to this library for library-level queries (aggregated movie items).

Testing

• tests/WLXMovieLibrary/ — per-module C++ tests.
• Contract coverage for the factory in tests/mmr-python.
• Exercise app: apps/movielibrary (submodule).
