Interface DefaultAudioSink.AudioProcessorChain

All Known Implementing Classes:

DefaultAudioSink.DefaultAudioProcessorChain

Enclosing class:

DefaultAudioSink

public static interface DefaultAudioSink.AudioProcessorChain

Provides a chain of audio processors, which are used for any user-defined processing and applying playback parameters (if supported). Because applying playback parameters can skip and stretch/compress audio, the sink will query the chain for information on how to transform its output position to map it onto a media position, via getMediaDuration(long) and getSkippedOutputFrameCount().

Method Summary

Modifier and Type	Method and Description
PlaybackParameters	applyPlaybackParameters(PlaybackParameters playbackParameters) Configures audio processors to apply the specified playback parameters immediately, returning the new parameters, which may differ from those passed in.
AudioProcessor[]	getAudioProcessors() Returns the fixed chain of audio processors that will process audio.
long	getMediaDuration(long playoutDuration) Scales the specified playout duration to take into account speedup due to audio processing, returning an input media duration, in arbitrary units.
long	getSkippedOutputFrameCount() Returns the number of output audio frames skipped since the audio processors were last flushed.

Method Detail

getAudioProcessors

AudioProcessor[] getAudioProcessors()

Returns the fixed chain of audio processors that will process audio. This method is called once during initialization, but audio processors may change state to become active/inactive during playback.

applyPlaybackParameters

PlaybackParameters applyPlaybackParameters(PlaybackParameters playbackParameters)

Configures audio processors to apply the specified playback parameters immediately, returning the new parameters, which may differ from those passed in. Only called when processors have no input pending.

Parameters:

playbackParameters - The playback parameters to try to apply.

Returns:

The playback parameters that were actually applied.

getMediaDuration

long getMediaDuration(long playoutDuration)

Scales the specified playout duration to take into account speedup due to audio processing, returning an input media duration, in arbitrary units.

getSkippedOutputFrameCount

long getSkippedOutputFrameCount()

Returns the number of output audio frames skipped since the audio processors were last flushed.
