Interface MediaProcessorListener

public interface MediaProcessorListener

MediaProcessorListener is an interface that may be used to receive events generated by a MediaProcessor. To use this interface, instantiate an object that implements this interface and pass it to the addMediaProcessorListener method of the MediaProcessor.

Field Summary

static java.lang.String	PROCESSING_ABORTED Posted to indicate that the processing has been aborted and the MediaProcessor has moved into UNREALIZED state.
static java.lang.String	PROCESSING_COMPLETED Posted to indicate that the processing has been completed and that the MediaProcessor has moved into UNREALIZED state.
static java.lang.String	PROCESSING_ERROR Posted to indicate that the processing was interrupted because of some error and the MediaProcessor has moved into REALIZED state.
static java.lang.String	PROCESSING_STARTED Posted to indicate that the MediaProcessor has moved into STARTED state and is processing input.
static java.lang.String	PROCESSING_STOPPED Posted to indicate that the MediaProcessor has moved into STOPPED state and paused processing.
static java.lang.String	PROCESSOR_REALIZED Posted to indicate that the processor has been moved from UNREALIZED into REALIZED state.

Method Summary

void	mediaProcessorUpdate(MediaProcessor processor, java.lang.String event, java.lang.Object eventData) This method is called to deliver an event to a registered listener when a MediaProcessor event is observed.
