构造方法详细信息

BasicProcessor

public BasicProcessor()

方法详细信息

isConfigurable

protected boolean isConfigurable()

A processor is configurable.

覆盖：

类 BasicPlayer 中的 isConfigurable

getTrackControls

public javax.media.control.TrackControl[] getTrackControls()
                                                    throws NotConfiguredError

Return the tracks in the media. This method can only be called after the Processor has been configured. A NotConfiguredError is thrown if getTrackControls is called and the Processor is in the Unrealized or Configuring states.

指定者：

接口 Processor 中的 getTrackControls

返回：

An array of the tracks in the media. An emtpy array is returned if there is no TrackControl available for this Processor.

抛出：

NotConfiguredError - if the Processor is Unrealized.

getSupportedContentDescriptors

public javax.media.protocol.ContentDescriptor[] getSupportedContentDescriptors()
                                                                        throws NotConfiguredError

Return all the content-types which this Processor's output supports. The Processor builds the ContentDescriptor array according to the input DataSource attached to the Processor and according to the codecs and multiplexers installed in the system.

指定者：

接口 Processor 中的 getSupportedContentDescriptors

返回：

An array of the the content-types supported by the Processor.

抛出：

NotConfiguredError - if the Processor is Unrealized.

setContentDescriptor

public javax.media.protocol.ContentDescriptor setContentDescriptor(javax.media.protocol.ContentDescriptor ocd)
                                                            throws NotConfiguredError

Set the output content-type. If setContentDescriptor is not called, the output DataSource's output will be on individual tracks.

指定者：

接口 Processor 中的 setContentDescriptor

参数：

outputContentDescriptor - the content-type of the output.

返回：

The content descriptor that most closely matches the specified content descriptor or null if the specified content descriptor cannot be set.

抛出：

NotConfiguredError - if the Processor is Unrealized. realized state and it does not support format changes after it has been realized.

getContentDescriptor

public javax.media.protocol.ContentDescriptor getContentDescriptor()
                                                            throws NotConfiguredError

Return the output content-type.

指定者：

接口 Processor 中的 getContentDescriptor

返回：

The current output content-type.

抛出：

NotConfiguredError - if the Processor is Unrealized.

getDataOutput

public javax.media.protocol.DataSource getDataOutput()
                                              throws NotRealizedError

Return the output DataSource of the Processor. The output DataSource is the output connection of the Processor through which it supplies the processed streams.

指定者：

接口 Processor 中的 getDataOutput

返回：

The output DataSource of the Processor.

抛出：

NotRealizedError - if the Processor is not realized.
