DirectShow (Windows CE 5.0)

Send Feedback

DirectShow® is a middleware architecture that provides a pipeline for media playback and capture. The DirectShow API enables playback of multimedia content from local storage or from streamed sources over a network, or the Internet. The architecture is designed to support sources, formats, codecs, and hardware devices.

DirectShow uses filters to manage and manipulate multimedia data. These filters perform actions, such as parsing, decoding, formatting, or rendering, on a multimedia streams. You can extend DirectShow media support by writing your own filters.

The output of one filter can be directed to the input of one or more other filters in what is called a filter graph. By constructing filter graphs using the Filter Graph Manager (FGM), you can use DirectShow as a flexible intermediary to translate various types of input into various types of output.

Microsoft DirectShow allows for high-quality playback of multimedia streams by supporting codecs for a variety of formats, including the following:

  • Advanced Streaming Format (ASF)
  • Motion Picture Experts Group (MPEG)
  • Audio-Video Interleaved (AVI)
  • MPEG Audio Layer-3 (MP3)
  • Waveform Audio (WAV)
  • Windows Media Audio and Video (WMA and WMV)

The codecs available on a Windows CE device depend on the OS design for that device.
