Detailed Description

Frames per second computation for a stream.

Public Member Functions
void	connect (Stream *stream)
	Connects to a stream's signals.

void	disconnect (Stream *stream)
	Disconnects from a stream's signals.

void	setUseDeviceTimestamp (bool flag)
	Use the device vs. arrival timestamp (default is false)

void	setNumberOfFrames (int val)
	Set the number of frames to use for computing the FPS (default is 10)

void	setRounding (int digits)
	Round FPS to the provided decimal digits, disabled if negative (default is 0)

void	setUpdateInterval (double seconds)
	Set upper limit on how frequently to recompute the FPS.

double	fps ()
	Return current FPS or zero if not available yet, and also resets the changed flag.

bool	changed () const
	Returns whether the FPS value has changed since it was last retrieved.

Public Member Functions inherited from SignalReceiver

	Default constructor.

	SignalReceiver (const SignalReceiver &other)
	Copy constructor, does not copy any existing signal connections from other.

SignalReceiver &	operator= (SignalReceiver rhs)
	Assignment operator, disconnects all existing connections, does not copy any existing signal connections from rhs.

virtual	~SignalReceiver ()
	Virtual destructor disconnects from all connected signals.
