Method Summary

Modifier and Type	Method	Description
void	run(AudioFormatInfo info, Set<AudioPackFlags> flags, @org.jspecify.annotations.Nullable byte @Nullable [] src, @org.jspecify.annotations.Nullable byte @Nullable [] data, int length)	Packs length samples from src to the data array in format info. The samples from source have each channel interleaved and will be packed into data.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, int, java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, int) method.
default void	upcall(MemorySegment info, int flags, MemorySegment src, MemorySegment data, int length)	The upcall method is called from native code.

Method Details

run

void run(AudioFormatInfo info,
 Set<AudioPackFlags> flags,
 @org.jspecify.annotations.Nullable byte @Nullable [] src,
 @org.jspecify.annotations.Nullable byte @Nullable [] data,
 int length)

Packs length samples from src to the data array in format info. The samples from source have each channel interleaved and will be packed into data.

upcall

default void upcall(MemorySegment info,
 int flags,
 MemorySegment src,
 MemorySegment data,
 int length)

The upcall method is called from native code. The parameters are marshaled and run(org.freedesktop.gstreamer.audio.AudioFormatInfo, java.util.Set<org.freedesktop.gstreamer.audio.AudioPackFlags>, byte[], byte[], int) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, int, java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, int) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
