Class DMO

java.lang.Object
  de.humatic.dsj.com.DMO

All Implemented Interfaces:

COMObject

Direct Known Subclasses:

DMOAudioEffect, DMOVideoEffect

public class DMO
extends java.lang.Object
implements COMObject

Baseclass for DMO (DirectX Media Object) implementations. DMO's are media processing units that can be hosted in various architectures (DirectShow, WindowsMedia FormatSDK, MediaFoundation). In DirectShow they are used via a DMOWrapperFilter and - apart from parameter control, which this class or its subclasses provide - can be mostly treated like classic DirectShow filters. To get hold of a DMO object use COMFactory.queryInterface(..) on the wrapper filter with an interface ID of IID_IMediaObject and cast the returned COMObject to either DMO, DMOAudio- or DMOVideoEffect.
Windows uses a unified parameter type, defined as MP_DATA, with DMOs which always is 32 bit long, but may be interpreted as int, float, bool etc. dsj uses floats instead, because most parameters actually take float values. You can simply cast int values to float and use 1 for true / 0 for for false where needed.
