Renderer

public interface Renderer implements PlugIn

A Renderer is a media processing unit that renders input media to a pre-defined destination, such as the screen or system speaker. It has one input and no outputs--rendering is the final stage of the media processing pipeline.

If a Renderer implements the Clock interface, it can be used by a Player as the master time base for synchronization. In this case, the Renderer should update the media time and time-base time as it processes the media.

since: JMF 2.0

public javax.media.Format setInputFormat(javax.media.Format format)
Sets the Format of the input data.
return

public void stop()
Halts the rendering process.
