Method Summary

Modifier and Type	Method	Description
void	run(AudioFormatInfo info, Set<AudioPackFlags> flags, byte[] dest, byte[] data, int length)	Unpacks length samples from the given data of format info.
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 dest, MemorySegment data, int length)	The upcall method is called from native code.

Method Details

run

void run(AudioFormatInfo info,
 Set<AudioPackFlags> flags,
 byte[] dest,
 byte[] data,
 int length)

Unpacks length samples from the given data of format info. The samples will be unpacked into dest which each channel interleaved. dest should at least be big enough to hold length * channels * size(unpack_format) bytes.

upcall

default void upcall(MemorySegment info,
 int flags,
 MemorySegment dest,
 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 function pointer will be allocated in this arena

Returns:

the native function pointer
