| Microsoft DirectX 8.1 (C++) |
Microsoft® DirectShow® must work on multiple platforms; in particular, it also runs on Microsoft Windows NT® 3.51, which does not have DirectDraw® capabilities. The filters therefore cannot link statically to the DirectDraw library. To make the platform dependencies easier to handle, this class manages loading and unloading the library and creating the initial IDirectDraw interface.
