DirectX and Windows Media Technologies DirectX gives a developer fast low-level access to a system's sound and graphics hardware while continuing to operate through the high-level features of Windows CE's Win32 interfaces. It lets you interact with video and audio hardware installed on your system in a device-independent manner. You can improve an existing device or implement a new system together with its driver, without having to rewrite your application code. In addition, by adding Microsoft DirectShow® and Windows Media Technologies, DirectX provides the developer easy APIs to stream, parse, decode, and render compressed multimedia audio and video data streams. DirectX is built on Microsoft's Component Object Model (COM) and consists of a set of fast low-level libraries that you can call to create and use objects such as surfaces, palettes, textures, lobbies, sound buffers, and musical instruments. Layered over these low-level interfaces are APIs for implementing consumer audio and video devices, as well as broadband and Internet multimedia streaming. We will be releasing the first Windows CE Platform Builder DirectX components this summer as part of Windows CE 2.12 DXPAK. It contains the following multimedia components: * DirectDraw®—2D graphics, including memory management, fast bit block transfers, overlays, and flips, all compatible with GDI. * DirectSound®—capturing, mixing, and playing sounds. * DirectShow®—playback of multimedia audio and video streams and files, support for multimedia codecs. * Windows Media® Player (WMP)—Microsoft ActiveX® controls for playback of all major multimedia types using DirectShow. Additional DirectX DXPAK components planned for future Windows CE releases include: * DirectMusic®—composition and playback of message-based musical data. * Direct3D® Immediate Mode (IM)—interactive 3D graphics and rendering. * DirectPlay®—networked multi-player gaming. * DirectInput®—personal input devices, including force feedback. (DirectInput is already available as part of the core Windows CE 2.12 release.) * Windows Media Services (WMS) client filters and codecs—multimedia streaming over the Internet, including support for low-bandwidth connections using MSAudio and MS MPEG-4 video. Selected components of Windows CE DirectX 6 and media technologies will be available as part of Windows CE 2.12 on the X86, MIPS R4300, and SH4 CPUs. Additional DirectX media components, especially those needed for DVD and home electronics devices, and enhanced support for Windows CE CPUs, are planned for future DXPAK releases. Windows CE for Dreamcast already contains DirectDraw, DirectSound, DirectMusic, Direct3D IM, DirectInput, and DirectPlay. These highly optimized, driver-based implementations are particular to the Sega Dreamcast hardware and are available as a separate SDK, but they are not part of the general Windows CE DXPAK releases. We will have much more to say about Dreamcast later in this article.
