Function Documentation

PLAYERC_EXPORT playerc_ptz_t* playerc_ptz_create	(	playerc_client_t *	client,
		int	index
	)

Create a ptz proxy.

PLAYERC_EXPORT void playerc_ptz_destroy ( playerc_ptz_t * device )

Destroy a ptz proxy.

PLAYERC_EXPORT int playerc_ptz_query_status ( playerc_ptz_t * device )

Query the pan and tilt status.

Parameters:

device Pointer to proxy object.

PLAYERC_EXPORT int playerc_ptz_set	(	playerc_ptz_t *	device,
		double	pan,
		double	tilt,
		double	zoom
	)

Set the pan, tilt and zoom values.

Parameters:

device	Pointer to proxy object.
pan	Pan value, in radians; 0 = centered.
tilt	Tilt value, in radians; 0 = level.
zoom	Zoom value, in radians (corresponds to camera field of view).

PLAYERC_EXPORT int playerc_ptz_set_control_mode	(	playerc_ptz_t *	device,
		int	mode
	)

Change control mode (select velocity or position control)

Parameters:

device	Pointer to proxy object.
mode	Desired mode (PLAYER_PTZ_VELOCITY_CONTROL or PLAYER_PTZ_POSITION_CONTROL)

PLAYERC_EXPORT int playerc_ptz_set_ws	(	playerc_ptz_t *	device,
		double	pan,
		double	tilt,
		double	zoom,
		double	panspeed,
		double	tiltspeed
	)

Set the pan, tilt and zoom values (and speed)

Parameters:

device	Pointer to proxy object.
pan	Pan value, in radians; 0 = centered.
tilt	Tilt value, in radians; 0 = level.
zoom	Zoom value, in radians (corresponds to camera field of view).
panspeed	Pan speed, in radians/sec.
tiltspeed	Tilt speed, in radians/sec.

PLAYERC_EXPORT int playerc_ptz_subscribe	(	playerc_ptz_t *	device,
		int	access
	)

Subscribe to the ptz device.

PLAYERC_EXPORT int playerc_ptz_unsubscribe ( playerc_ptz_t * device )

Un-subscribe from the ptz device.
