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.
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.

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

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.
