Constructor Detail

DataSource

public DataSource()

Initializes a new DataSource instance.

DataSource

public DataSource(javax.media.MediaLocator locator)

Initializes a new DataSource instance.

Parameters:

locator - associated MediaLocator

Method Detail

setOrigin

public void setOrigin(int streamIndex,
                      int monitorIndex,
                      int x,
                      int y)

Set origin of ImageStream.

Parameters:

streamIndex - stream index

monitorIndex - monitor index

x - x coordinate

y - y coordinate

createStream

protected AbstractPullBufferStream 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
