Method Details

run

boolean run(CapsFeatures features,
 Structure structure)

A function that will be called in gst_caps_filter_and_map_in_place(). The function may modify features and structure, and both will be removed from the caps if false is returned.

Parameters:

features - the GstCapsFeatures

structure - the GstStructure

Returns:

true if the features and structure should be preserved, false if it should be removed.

upcall

default int upcall(MemorySegment features,
 MemorySegment structure,
 MemorySegment userData)

The upcall method is called from native code. The parameters are marshaled and run(CapsFeatures, Structure) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

Parameters:

arena - the arena in which the function pointer is allocated
