An earlier version of the documentation stated that this filter can decode "MPEG-2 audio. For streams with a channel configuration of two or more speakers, the decoder does one of the following:. Alternatively, when the application builds the filter graph, it can set the desired media type on the output pin. The DirectShow decoder also accepts different input types than the Media Foundation decoder. The decoder's input pin supports the following property sets through IKsPropertySet :.
Starting in Windows 7, the decoder supports trick mode through the rate-change property set. It supports playback rates in the range [0. Skip to main content. This browser is no longer supported.

It creates that is, instantiates a device object for each data type to be decoded in hardware, such as audio and video data types. This filter supports plug-ins that allow expansion for new interfaces. These filters enable playback of video using hardware video ports, and provide support for blending low-bandwidth video streams, such as the closed caption decoder output stream.
Dedicated buses transfer decoded video streams from an MPEG-2 decoder to the display card. Microsoft provides software support for these interfaces by using the DirectDraw hardware abstraction layer HAL with video port extensions VPE to pass video that was decoded in hardware to the video graphics array VGA. Copyright protection for DVD is provided by encrypting sectors on a disc and then decrypting those sectors before decoding them.
