Constructor & Destructor Documentation

◆ IPTVSignalMonitor() [1/3]

IPTVSignalMonitor::IPTVSignalMonitor	(	int	db_cardnum,
		IPTVChannel *	_channel,
		bool	_release_stream,
		uint64_t	_flags = `0`
	)

Initializes signal lock and signal values.

Start() must be called to actually begin continuous signal monitoring. The timeout is set to 3 seconds, and the signal threshold is initialized to 0%.

Parameters

db_cardnum	Recorder number to monitor, if this is less than 0, SIGNAL events will not be sent to the frontend even if SetNotifyFrontend(true) is called.
_channel	IPTVChannel for card
_flags	Flags to start with
