Constructor Detail

FFAudioInputStream

public FFAudioInputStream(FFNativePeerInputStream nativePeerInputStream,
                          AudioFormat format,
                          long frameLength)

Creates a new FFAudioInputStream backed by the given native peer.

Parameters:

nativePeerInputStream - native peer that reads and decodes audio data

format - audio format of the decoded PCM data

frameLength - total frame count, or AudioSystem.NOT_SPECIFIED

Method Detail

getFrameLength

public long getFrameLength()

Overrides:

getFrameLength in class AudioInputStream

isSeekable

public boolean isSeekable()

Indicates whether this stream is seekable. Typically, stream based streams (as opposed to file-based streams) are not seekable.

Returns:

true or false

seek

public void seek(long time,
                 TimeUnit timeUnit)
          throws UnsupportedOperationException,
                 IOException

Positions the stream at the desired timestamp.

Parameters:

time - time

timeUnit - time unit

Throws:

UnsupportedOperationException - if the operation is not supported

IOException - if something goes wrong
