Constructor Summary

AudioMediaDeviceImpl()
Initializes a new AudioMediaDeviceImpl instance which represents a MediaDevice with MediaType AUDIO and a MediaDirection which does not allow sending.

AudioMediaDeviceImpl(javax.media.CaptureDeviceInfo captureDeviceInfo)
Initializes a new AudioMediaDeviceImpl which is to provide an implementation of MediaDevice with MediaType AUDIO to a CaptureDevice with a specific CaptureDeviceInfo.

Method Summary

void	connect(javax.media.protocol.DataSource captureDevice) Connects to a specific CaptureDevice given in the form of a DataSource.
(package private) javax.media.protocol.CaptureDevice	createCaptureDevice() Creates the JMF CaptureDevice this instance represents and provides an implementation of MediaDevice for.
(package private) javax.media.Renderer	createRenderer() Initializes a new Renderer instance which is to play back media on this MediaDevice.
List<RTPExtension>	getSupportedExtensions() Returns a List containing (at the time of writing) a single extension descriptor indicating RECVONLY support for mixer-to-client audio levels.
protected javax.media.protocol.CaptureDevice	superCreateCaptureDevice() Invokes the super (with respect to the AudioMediaDeviceImpl class) implementation of MediaDeviceImpl.createCaptureDevice().

Constructor Detail

AudioMediaDeviceImpl

public AudioMediaDeviceImpl()

Initializes a new AudioMediaDeviceImpl instance which represents a MediaDevice with MediaType AUDIO and a MediaDirection which does not allow sending.

AudioMediaDeviceImpl

public AudioMediaDeviceImpl(javax.media.CaptureDeviceInfo captureDeviceInfo)

Initializes a new AudioMediaDeviceImpl which is to provide an implementation of MediaDevice with MediaType AUDIO to a CaptureDevice with a specific CaptureDeviceInfo.

Parameters:

captureDeviceInfo - the CaptureDeviceInfo of the CaptureDevice to which the new instance is to provide an implementation of MediaDevice

Method Detail

connect

public void connect(javax.media.protocol.DataSource captureDevice)
             throws IOException

Connects to a specific CaptureDevice given in the form of a DataSource.

Overrides:

connect in class AbstractMediaDevice

Parameters:

captureDevice - the CaptureDevice to be connected to

Throws:

IOException - if anything wrong happens while connecting to the specified captureDevice

See Also:

AbstractMediaDevice.connect(DataSource)

createCaptureDevice

javax.media.protocol.CaptureDevice createCaptureDevice()

Creates the JMF CaptureDevice this instance represents and provides an implementation of MediaDevice for.

Overrides:

createCaptureDevice in class MediaDeviceImpl

Returns:

the JMF CaptureDevice this instance represents and provides an implementation of MediaDevice for; null if the creation fails

createRenderer

javax.media.Renderer createRenderer()

Initializes a new Renderer instance which is to play back media on this MediaDevice.

Overrides:

createRenderer in class MediaDeviceImpl

Returns:

a new Renderer instance which is to play back media on this MediaDevice or null if a suitable Renderer is to be chosen irrespective of this MediaDevice

getSupportedExtensions

public List<RTPExtension> getSupportedExtensions()

Returns a List containing (at the time of writing) a single extension descriptor indicating RECVONLY support for mixer-to-client audio levels.

Specified by:

getSupportedExtensions in interface MediaDevice

Overrides:

getSupportedExtensions in class AbstractMediaDevice

Returns:

a List containing the CSRC_AUDIO_LEVEL_URN extension descriptor.

superCreateCaptureDevice

protected javax.media.protocol.CaptureDevice superCreateCaptureDevice()

Invokes the super (with respect to the AudioMediaDeviceImpl class) implementation of MediaDeviceImpl.createCaptureDevice(). Allows this instance to customize the very CaptureDevice which is to be possibly further wrapped by this instance.

Returns:

the CaptureDevice returned by the call to the super implementation of MediaDeviceImpl#createCaptureDevice.
