Architecture
The Microsoft® Windows Media™ Player control is built on Microsoft® DirectShow® technology. DirectShow is based on Component Object Model (COM) architecture, which employs components called filters that can be plugged in to process multimedia data. Each filter is designed to receive digital input, process the data, and pass the results on to the next filter. The filters are arranged in a configuration called a filter graph.
DirectShow technology is based on several Microsoft services, including:
- Microsoft® DirectDraw® for two-dimensional graphics hardware acceleration.
- Microsoft® DirectSound® for audio mixing and low-latency audio.
- Microsoft® Direct3D® for three-dimensional graphics hardware acceleration.
Filters and filter graphs can be created by implementing COM interfaces that use the class libraries and documentation provided by the DirectShow Software Development Kit (SDK). However, it is not necessary to understand Microsoft® Visual C++® programming or COM to use the Windows Media Player control.
The following diagram illustrates the relationship between DirectShow and the Windows Media Player control.
