IMFMediaBuffer Interface

Represents a block of memory that contains media data. Use this interface to access the data in the buffer.

Syntax

interface IMFMediaBuffer : public IUnknown

Remarks

If the buffer contains 2-D image data (such as an uncompressed video frame), you should query the buffer for the IMF2DBuffer interface. The methods on IMF2DBuffer are optimized for 2-D data.

To get a buffer from a media sample, call one of the following IMFSample methods:

IMFSample::ConvertToContiguousBuffer
IMFSample::GetBufferByIndex

To create a new buffer object, use one of the following functions.

Function	Description
MFCreateMemoryBuffer	Creates a buffer and allocates system memory.
MFCreateMediaBufferWrapper	Creates a media buffer that wraps an existing media buffer.
MFCreateDXSurfaceBuffer	Creates a buffer that manages a DirectX surface.
MFCreateAlignedMemoryBuffer	Creates a buffer and allocates system memory with a specified alignment.

Header: Declared in mfobjects.h (include mfidl.h).
