MovieBuilder.ImageDataSource(int width, int height, int frameRate, java.util.Vector images)

Method Summary

void	connect()
void	disconnect()
java.lang.String	getContentType() Content type is of RAW since we are sending buffers of video frames without a container format.
java.lang.Object	getControl(java.lang.String type)
java.lang.Object[]	getControls()
javax.media.Time	getDuration() We could have derived the duration from the number of frames and frame rate.
javax.media.MediaLocator	getLocator()
javax.media.protocol.PullBufferStream[]	getStreams() Return the ImageSourceStreams.
void	setLocator(javax.media.MediaLocator source)
void	start()

Method Detail

setLocator

public void setLocator(javax.media.MediaLocator source)

Overrides:

setLocator in class javax.media.protocol.DataSource

getLocator

public javax.media.MediaLocator getLocator()

Overrides:

getLocator in class javax.media.protocol.DataSource

getContentType

public java.lang.String getContentType()

Content type is of RAW since we are sending buffers of video frames without a container format.

Overrides:

getContentType in class javax.media.protocol.DataSource

connect

public void connect()

Overrides:

connect in class javax.media.protocol.DataSource

disconnect

public void disconnect()

Overrides:

disconnect in class javax.media.protocol.DataSource

start

public void start()

Overrides:

start in class javax.media.protocol.DataSource

stop

public void stop()

Overrides:

stop in class javax.media.protocol.DataSource

getStreams

public javax.media.protocol.PullBufferStream[] getStreams()

Return the ImageSourceStreams.

Overrides:

getStreams in class javax.media.protocol.PullBufferDataSource

getDuration

public javax.media.Time getDuration()

We could have derived the duration from the number of frames and frame rate. But for the purpose of this program, it's not necessary.
