Constructor Detail

RecorderRtpImpl

public RecorderRtpImpl(RTPTranslator translator)

Constructor.

Parameters:

translator - the RTPTranslator to which this instance will attach in order to record media.

Method Detail

addListener

public void addListener(Recorder.Listener listener)

Implements Recorder.addListener(Recorder.Listener).

Specified by:

addListener in interface Recorder

Parameters:

listener - the new Listener to be added to the list of listeners interested in notifications from this Recorder

removeListener

public void removeListener(Recorder.Listener listener)

Implements Recorder.removeListener(Recorder.Listener).

Specified by:

removeListener in interface Recorder

Parameters:

listener - the existing Listener to be removed from the list of listeners interested in notifications from this Recorder

getSupportedFormats

public List<String> getSupportedFormats()

Implements Recorder.getSupportedFormats().

Specified by:

getSupportedFormats in interface Recorder

Returns:

a List of the formats in which this Recorder supports recording media

setMute

public void setMute(boolean mute)

Implements Recorder.setMute(boolean).

Specified by:

setMute in interface Recorder

Parameters:

mute - the new value of the mute property

getFilename

public String getFilename()

Implements Recorder.getFilename(). Returns null, since we don't have a (single) associated filename.

Specified by:

getFilename in interface Recorder

Returns:

the filename we are last started or stopped recording to, null if not started.

setEventHandler

public void setEventHandler(RecorderEventHandler eventHandler)

Sets the instance which should be notified when events related to recordings (such as the start or end of a recording) occur.

Specified by:

setEventHandler in interface Recorder

Parameters:

eventHandler - the RecorderEventHandler to set.

start

public void start(String format,
                  String dirname)
           throws IOException,
                  MediaException

Starts the recording of the media associated with this Recorder (e.g. the media being sent and received in a Call) into a file with a specific name.

Specified by:

start in interface Recorder

Parameters:

format - unused, since this implementation records multiple streams using potentially different formats.

dirname - the path to the directory into which this Recorder will store the recorded media files.

Throws:

IOException - if anything goes wrong with the input and/or output performed by this Recorder

MediaException - if anything else goes wrong while starting the recording of media performed by this Recorder

getMediaStream

public MediaStream getMediaStream()

Gets the MediaStream associated with this Recorder.

Specified by:

getMediaStream in interface Recorder

Returns:

the MediaStream associated with this Recorder.

stop

public void stop()

Description copied from interface: Recorder

Stops the recording of the media associated with this Recorder (e.g. the media being sent and received in a Call) if it has been started and prepares this Recorder for garbage collection.

Specified by:

stop in interface Recorder

update

public void update(javax.media.rtp.event.ReceiveStreamEvent event)

Implements ReceiveStreamListener.update(ReceiveStreamEvent). rtpManager will use this to notify us of ReceiveStreamEvents.

Specified by:

update in interface javax.media.rtp.ReceiveStreamListener

controllerUpdate

public void controllerUpdate(javax.media.ControllerEvent ev)

Implements ControllerListener.controllerUpdate(ControllerEvent). Handles events from the Processors that this instance uses to transcode media.

Specified by:

controllerUpdate in interface javax.media.ControllerListener

Parameters:

ev - the event to handle.

activeSpeakerChanged

public void activeSpeakerChanged(Long ssrc)

Implements ActiveSpeakerChangedListener.activeSpeakerChanged(Object). Notifies this RecorderRtpImpl that the audio ReceiveStream considered active has changed, and that the new active stream has SSRC ssrc.

Specified by:

activeSpeakerChanged in interface org.jitsi.utils.dsi.ActiveSpeakerChangedListener<Long>

Parameters:

ssrc - the SSRC of the new active stream.

getSynchronizer

public SynchronizerImpl getSynchronizer()

Description copied from interface: Recorder

Gets the Synchronizer of this Recorder.

Specified by:

getSynchronizer in interface Recorder

Returns:

the Synchronizer of this Recorder.

setSynchronizer

public void setSynchronizer(Synchronizer synchronizer)

Description copied from interface: Recorder

Sets the Synchronizer that this instance should use.

Specified by:

setSynchronizer in interface Recorder

Parameters:

synchronizer - the Synchronizer to set.

connect

public void connect(Recorder recorder)
