Method Summary

Modifier and Type	Method	Description
FlowReturn	run(CollectPads pads, CollectData data, Buffer buffer)	A function that will be called when a (considered oldest) buffer can be muxed.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment) method.
default int	upcall(MemorySegment pads, MemorySegment data, MemorySegment buffer, MemorySegment userData)	The upcall method is called from native code.

Method Details

run

FlowReturn run(CollectPads pads,
 CollectData data,
 Buffer buffer)

A function that will be called when a (considered oldest) buffer can be muxed. If all pads have reached EOS, this function is called with null buffer and null data.

upcall

default int upcall(MemorySegment pads,
 MemorySegment data,
 MemorySegment buffer,
 MemorySegment userData)

The upcall method is called from native code. The parameters are marshaled and run(org.freedesktop.gstreamer.base.CollectPads, org.freedesktop.gstreamer.base.CollectData, org.freedesktop.gstreamer.gst.Buffer) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the function pointer will be allocated in this arena

Returns:

the native function pointer
