Class Recorder
java.lang.Object
org.openni.Recorder
The Recorder class is used to record streams to an ONI file.
After a recorder is instantiated, it must be initialized with a specific filename where the
recording will be stored. The recorder is then attached to one or more streams. Once this is
complete, the recorder can be told to start recording. The recorder will store every frame from
every stream to the specified file. Later, this file can be used to initialize a file Device, and
used to play back the same data that was recorded.
Opening a file device is done by passing its path as the uri to the
Device.open(String)
method.

Method Details

create
Initializes a recorder. You can initialize the recorder only once. Attempts to initialize more than once will result in an error code being returned. Initialization assigns the recorder to an output file that will be used for recording. Before use, theaddStream(VideoStream, boolean)
function must also be used to assign input data to the Recorder.- Parameters:
fileName
- The name of a file which will contain the recording.
-
getHandle
public long getHandle()This function return recorded handle.- Returns:
- OpenNI recorder handle.
-
addStream
Attaches a stream to the recorder. Note, this won't start recording, you should explicitly start it usingstart()
method. As soon as the recording process has been started, no more streams can be attached to the recorder.- Parameters:
stream
- The stream to be recorded.allowLossyCompression
- If this value is true, the recorder might use a lossy compression, which means that when the recording will be played-back, there might be small differences from the original frame. Default value is false.
-
start
public void start()Starts recording. Once this method is called, the recorder will take all subsequent frames from the attached streams and store them in the file. You may not add additional streams once recording was started. -
stop
public void stop()Stops recording. You may usestart()
to resume the recording. -
destroy
public void destroy()Destroys a recorder. This will also stop recording.
