Direct Known Subclasses:

AudioSink

@Generated("io.github.jwharm.JavaGI")
public class AudioBaseSink
extends BaseSink

This is the base class for audio sinks. Subclasses need to implement the ::create_ringbuffer vmethod. This base class will then take care of writing samples to the ringbuffer, synchronisation, clipping and flushing.

Constructor Details

AudioBaseSink

public AudioBaseSink(MemorySegment address)

Create a AudioBaseSink proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

getType

public static Type getType()

Get the GType of the AudioBaseSink class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected AudioBaseSink asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class BaseSink

createRingbuffer

public AudioRingBuffer createRingbuffer()

Create and return the GstAudioRingBuffer for this AudioBaseSink. This function will call the ::create_ringbuffer vmethod and will set this AudioBaseSink as the parent of the returned buffer (see gst_object_set_parent()).

Returns:

The new ringbuffer of this AudioBaseSink.

getAlignmentThreshold

public ClockTime getAlignmentThreshold()

Get the current alignment threshold, in nanoseconds, used by this AudioBaseSink.

Returns:

The current alignment threshold used by this AudioBaseSink.

getDiscontWait

public ClockTime getDiscontWait()

Get the current discont wait, in nanoseconds, used by this AudioBaseSink.

Returns:

The current discont wait used by this AudioBaseSink.

getDriftTolerance

public long getDriftTolerance()

Get the current drift tolerance, in microseconds, used by this AudioBaseSink.

Returns:

The current drift tolerance used by this AudioBaseSink.

getProvideClock

public boolean getProvideClock()

Queries whether this AudioBaseSink will provide a clock or not. See also gst_audio_base_sink_set_provide_clock.

Returns:

true if this AudioBaseSink will provide a clock.

getSlaveMethod

public AudioBaseSinkSlaveMethod getSlaveMethod()

Get the current slave method used by this AudioBaseSink.

Returns:

The current slave method used by this AudioBaseSink.

reportDeviceFailure

public void reportDeviceFailure()

Informs this base class that the audio output device has failed for some reason, causing a discontinuity (for example, because the device recovered from the error, but lost all contents of its ring buffer). This function is typically called by derived classes, and is useful for the custom slave method.

setAlignmentThreshold

public void setAlignmentThreshold(ClockTime alignmentThreshold)

Controls the sink's alignment threshold.

Parameters:

alignmentThreshold - the new alignment threshold in nanoseconds

setCustomSlavingCallback

public void setCustomSlavingCallback(AudioBaseSinkCustomSlavingCallback callback)

Sets the custom slaving callback. This callback will be invoked if the slave-method property is set to GST_AUDIO_BASE_SINK_SLAVE_CUSTOM and the audio sink receives and plays samples.

Setting the callback to NULL causes the sink to behave as if the GST_AUDIO_BASE_SINK_SLAVE_NONE method were used.

Parameters:

callback - a GstAudioBaseSinkCustomSlavingCallback

setDiscontWait

public void setDiscontWait(ClockTime discontWait)

Controls how long the sink will wait before creating a discontinuity.

Parameters:

discontWait - the new discont wait in nanoseconds

setDriftTolerance

public void setDriftTolerance(long driftTolerance)

Controls the sink's drift tolerance.

Parameters:

driftTolerance - the new drift tolerance in microseconds

setProvideClock

public void setProvideClock(boolean provide)

Controls whether this AudioBaseSink will provide a clock or not. If provide is true, gst_element_provide_clock() will return a clock that reflects the datarate of this AudioBaseSink. If provide is false, gst_element_provide_clock() will return NULL.

Parameters:

provide - new state

setSlaveMethod

public void setSlaveMethod(AudioBaseSinkSlaveMethod method)

Controls how clock slaving will be performed in this AudioBaseSink.

Parameters:

method - the new slave method

payload

protected Buffer payload(Buffer buffer)

payload data in a format suitable to write to the sink. If no payloading is required, returns a reffed copy of the original buffer, else returns the payloaded buffer with all other metadata copied.

builder

public static AudioBaseSink.Builder<? extends AudioBaseSink.Builder> builder()

A AudioBaseSink.Builder object constructs a AudioBaseSink with the specified properties. Use the various set...() methods to set properties, and finish construction with AudioBaseSink.Builder.build().
