IBitstreamProcessor (Windows Embedded CE 6.0)

1/6/2010

This interface is the primary initialization interface of the media renderer. The media renderer object should implement the IBitstreamProcessor interface. Methods in this interface are called by the metadriver in order to prepare the media driver to play a particular media type.

A pointer to an IBitstreamProcessor interface can be obtained by calling the IUnknown::QueryInterface method of a media renderer object and specifying the IID_IBitstreamProcessor reference identifier.

The IBitstreamProcessor interface exposes the following methods.

Method	Description
IBitstreamProcessor::Init	Initializes the microprocessor hardware.
IBitstreamProcessor::SetBitstreamType	Sets the bit-stream type to a defined value.
IBitstreamProcessor::GetLabeledDMAChannel	Retrieves the DMA channel by its name.
IBitstreamProcessor::GetDMAChannelCount	Returns the number of DMA channels for a previously selected bit-stream type.
IBitstreamProcessor::GetDMAChannel	Retrieves the DMA channel by index.

The IDVDTitleSet interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:

• AddRef
• QueryInterface
• Release
