The IMediaBuffer interface provides methods for manipulating a data buffer. Buffers passed to the IMediaObject::ProcessInput and ProcessOutput methods must implement this interface.
In addition to the methods inherited from IUnknown, the IMediaBuffer interface exposes the following methods.
| Method | Description |
| GetBufferAndLength | Retrieves the buffer and the size of the valid data in the buffer. |
| GetMaxLength | Retrieves the maximum number of bytes this buffer can hold. |
| SetLength | Specifies the length of the data currently in the buffer. |
