IMediaBuffer (Windows Embedded CE 6.0)

1/6/2010

This interface provides methods for manipulating a data buffer. Any buffer passed to a Microsoft DirectX Media Object (DMO) must implement this interface.

The following table shows the methods for IMediaBuffer in the order the compiler calls them.

Method	Description
SetLength	Specifies the length of the data currently in the buffer.
GetMaxLength	Retrieves the maximum number of bytes this buffer can hold.
GetBufferAndLength	Retrieves the buffer and the size of the valid data in the buffer.

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

• AddRef
• QueryInterface
• Release

Requirements

Header	dmo.h
Library	Dmoguid.lib
Windows Embedded CE	Windows CE .NET 4.1 and later
