Method Summary

Modifier and Type	Method	Description
int	run(CollectPads pads, CollectData data1, ClockTime timestamp1, CollectData data2, ClockTime timestamp2)	A function for comparing two timestamps of buffers or newsegments collected on one pad.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, MemorySegment, long, MemorySegment, long, MemorySegment) method.

Method Details

run

int run(CollectPads pads,
 CollectData data1,
 ClockTime timestamp1,
 CollectData data2,
 ClockTime timestamp2)

A function for comparing two timestamps of buffers or newsegments collected on one pad.

Parameters:

pads - the GstCollectPads that is comparing the timestamps

data1 - the first GstCollectData

timestamp1 - the first timestamp

data2 - the second GstCollectData

timestamp2 - the second timestamp

Returns:

Integer less than zero when first timestamp is deemed older than the second one. Zero if the timestamps are deemed equally old. Integer greater than zero when second timestamp is deemed older than the first one.

upcall

default int upcall(MemorySegment pads,
 MemorySegment data1,
 long timestamp1,
 MemorySegment data2,
 long timestamp2,
 MemorySegment userData)

The upcall method is called from native code. The parameters are marshaled and run(CollectPads, CollectData, ClockTime, CollectData, ClockTime) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(MemorySegment, MemorySegment, long, MemorySegment, long, MemorySegment) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
