Member Function Documentation

◆ Main()

void CameraUvc::Main ( )

privatevirtual

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.

Implements ThreadedDriver.

References PLAYER_CAMERA_COMPRESS_JPEG, PLAYER_CAMERA_DATA_STATE, PLAYER_CAMERA_FORMAT_RGB888, and PLAYER_MSGTYPE_DATA.

◆ MainQuit()

void CameraUvc::MainQuit ( void )

virtual

Cleanup method for driver thread (called when main exits)

Overload this method and to do additional cleanup when the driver thread exits.

Reimplemented from ThreadedDriver.

◆ ProcessMessage()

int CameraUvc::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.
