@Generated("org.javagi.JavaGI")
public abstract class AudioVisualizer
extends Element

A baseclass for scopes (visualizers). It takes care of re-fitting the audio-rate to video-rate and handles renegotiation (downstream video size changes).

It also provides several background shading effects. These effects are applied to a previous picture before the render() implementation can draw a new frame.

Constructor Details

AudioVisualizer

public AudioVisualizer(MemorySegment address)

Create a AudioVisualizer instance for the provided memory address.

Parameters:

address - the memory address of the native object

AudioVisualizer

public AudioVisualizer()

Create a new AudioVisualizer.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the AudioVisualizer class.

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected AudioVisualizer asParent()

Return this instance as if it were its parent type. Comparable to the Java super keyword, but ensures the parent typeclass is also used in native code.

Overrides:

asParent in class Element

Returns:

the instance as if it were its parent type

decideAllocation

protected boolean decideAllocation(Query query)

render

protected boolean render(Buffer audio,
 VideoFrame video)

setup

protected boolean setup()
