setAppSinkAdaptersActive()

void GStreamer::setAppSinkAdaptersActive	(	QObject *	adapterParent,
		bool	active
	)

Toggle every appsink adapter parented under adapterParent. Used to drop frames at the appsink while the host window is hidden/minimized — saves CPU vs. running the full decode→render path against a non-visible sink. Safe to call repeatedly; no-op when no adapters exist.
