All Implemented Interfaces:

AudioObject, AudioSink, javax.media.ControllerListener, javax.media.datasink.DataSinkListener

public class AudioMediaURLSink

extends DefaultAudioSink

implements javax.media.ControllerListener, javax.media.datasink.DataSinkListener

Writes audio data to a URL using the JMF packages, with content type defined by one of the FileTypeDescriptor String fields, eg MPEG_AUDIO, QUICKTIME etc

Note: AudioSources that have an AudioFormat that is big-endian, or 8-bit often produce bad results.

Constructor Summary

AudioMediaURLSink(java.net.URL url, java.lang.String outputContentType)
contentType should be one of the FileTypeDescriptor String fields, eg MPEG_AUDIO, QUICKTIME etc

Method Summary

void	controllerUpdate(javax.media.ControllerEvent evt)
void	dataSinkUpdate(javax.media.datasink.DataSinkEvent evt)
boolean	getKeepOpen()
void	setKeepOpen(boolean keepOpen) Used to keep the sink open even after receiving zero bytes from it's attached source - this allows RTP streams to operate correctly.
int	write(byte[] data, int offset, int length) Used to write data to this sink - called by the AudioSource which this sink is connected to (if its startSending method is used) so need not be called explicitly by an application.
