Method Detail

createStream

protected org.jitsi.impl.neomedia.jmfext.media.protocol.pulseaudio.DataSource.PulseAudioStream createStream(int streamIndex,
                                                                                                            javax.media.control.FormatControl formatControl)

Creates a new PullBufferStream which is to be at a specific zero-based index in the list of streams of this PullBufferDataSource. The Format-related information of the new instance is to be abstracted by a specific FormatControl.

Specified by:

createStream in class AbstractPullBufferCaptureDevice

Parameters:

streamIndex - the zero-based index of the PullBufferStream in the list of streams of this PullBufferDataSource

formatControl - the FormatControl which is to abstract the Format-related information of the new instance

Returns:

a new PullBufferStream which is to be at the specified streamIndex in the list of streams of this PullBufferDataSource and which has its Format-related information abstracted by the specified formatControl

doDisconnect

protected void doDisconnect()

Closes the connection to the media source specified by the MediaLocator of this DataSource. Allows extenders to override and be sure that there will be no request to close a connection if the connection has not been opened yet.

Overrides:

doDisconnect in class AbstractPullBufferCaptureDevice
