Method Summary

Modifier and Type	Method	Description
void	run(@Nullable Element source)	This signal is emitted after the source element has been created for, so the URI being discovered, so it can be configured by setting additional properties (e.g. set a proxy server for an http source, or set the device and read speed for an audio cd source).

Method Details

run

void run(@Nullable Element source)

This signal is emitted after the source element has been created for, so the URI being discovered, so it can be configured by setting additional properties (e.g. set a proxy server for an http source, or set the device and read speed for an audio cd source).

This signal is usually emitted from the context of a GStreamer streaming thread.

upcall

default void upcall(MemorySegment sourceDiscoverer,
 MemorySegment source)

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

toCallback

default MemorySegment toCallback(Arena arena)

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

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
