Method Details

run

void run(DiscovererInfo info,
 @Nullable
 @Nullable GError error)

Will be emitted in async mode when all information on a URI could be discovered, or an error occurred.

When an error occurs, info might still contain some partial information, depending on the circumstances of the error.

upcall

 MemorySegment info,
 MemorySegment error)

The upcall method is called from native code. The parameters are marshaled and run(org.freedesktop.gstreamer.pbutils.DiscovererInfo, org.gnome.glib.GError) is executed.

toCallback
