Method Details

run

FlowReturn run(CollectPads pads,
 CollectData data,
 Buffer inbuffer,
 Out<Buffer> outbuffer)

A function that will be called when inbuffer is received on the pad managed by data in the collectpad object pads.

The function should use the segment of data and the negotiated media type on the pad to perform clipping of inbuffer.

This function takes ownership of inbuffer and should output a buffer in outbuffer or return null in outbuffer if the buffer should be dropped.

upcall

default int upcall(MemorySegment pads,
 MemorySegment data,
 MemorySegment inbuffer,
 MemorySegment outbuffer,
 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, io.github.jwharm.javagi.base.Out<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, 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
