Method Summary

Modifier and Type	Method	Description
void	run(Segment segment, long pts, long dts, long duration, @Nullable Structure info)	Signals that the GstAggregator subclass has selected the next set of input samples it will aggregate.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment, long, long, long, java.lang.foreign.MemorySegment) method.
default void	upcall(MemorySegment sourceAggregator, MemorySegment segment, long pts, long dts, long duration, MemorySegment info)	The upcall method is called from native code.

Method Details

run

void run(Segment segment,
 long pts,
 long dts,
 long duration,
 @Nullable
 @Nullable Structure info)

Signals that the GstAggregator subclass has selected the next set of input samples it will aggregate. Handlers may call gst_aggregator_peek_next_sample() at that point.

upcall

default void upcall(MemorySegment sourceAggregator,
 MemorySegment segment,
 long pts,
 long dts,
 long duration,
 MemorySegment info)

The upcall method is called from native code. The parameters are marshaled and run(org.freedesktop.gstreamer.gst.Segment, long, long, long, org.freedesktop.gstreamer.gst.Structure) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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