Member Function Documentation

void SphereDriver::Main

(

)

[virtual]

Main method for driver thread.

drivers have their own thread of execution, created using StartThread(); this is the entry point for the driver thread, and must be overloaded by all threaded drivers.

Reimplemented from Driver.

References Driver::ProcessMessages().

Here is the call graph for this function:

int SphereDriver::ProcessMessage	(	QueuePointer &	resp_queue,
		player_msghdr *	hdr,
		void *	data
	)			[virtual]

Message handler.

This function is called once for each message in the incoming queue. Reimplement it to provide message handling. Return 0 if you handled the message and -1 otherwise

Parameters:

	resp_queue	The queue to which any response should go.
	hdr	The message header
	data	The message body

Reimplemented from Driver.

References Driver::device_addr, Message::MatchMessage(), PLAYER_ERROR1, PLAYER_MSGTYPE_CMD, PLAYER_MSGTYPE_REQ, PLAYER_MSGTYPE_RESP_ACK, PLAYER_PTZ_CMD_STATE, PLAYER_PTZ_REQ_STATUS, Driver::Publish(), player_msghdr::size, and player_msghdr::type.

Here is the call graph for this function:

int SphereDriver::Setup

(

)

[virtual]

Initialize the driver.

This function is called with the first client subscribes; it MUST be implemented by the driver.

Returns:

Returns 0 on success.

Implements Driver.

References player_camera_data::format, PlayerCc::max(), PlayerCc::min(), PLAYER_CAMERA_FORMAT_MONO8, PLAYER_CAMERA_FORMAT_RGB888, and PLAYER_ERROR.

Here is the call graph for this function:

int SphereDriver::Shutdown

(

)

[virtual]

Finalize the driver.

This function is called with the last client unsubscribes; it MUST be implemented by the driver.

Returns:

Returns 0 on success.

Implements Driver.

References Driver::StopThread().

Here is the call graph for this function:

void SphereDriver::YUV422toRGB	(	uint8_t *	argInputData,
		uint8_t *	argOutputData
	)			[private]

Conversion of YUV422 pixel data into RGB ( CCIR 601 ).

R = (Y - 16) * 1.164 + (V-128) * 1.596 G = (Y - 16) * 1.164 - (U-128) * 0.391 - (V-128) * 0.813 B = (Y - 16) * 1.164 + (U-128) * 2.018

The formulas are approximated by

R = Y * (291/250) + V * (399/250) - 223 G = Y * (291/250) + U * (319/1000) - V * (813/1000) + 35 B = Y * (291/250) + U * (1009/500) - 277
