Detailed Description

RTSP State Machine, dispatches incoming events to the corrent handler.

Function Documentation

int init_state	(	rtsp_thread *	rtsp_th,
		short	event
	)

Handles RTSP events when the controller is in INIT state

Parameters:

	rtsp_th	The controller for which to handle the events
	event	The event generated by handle_rtsp_pkt

Returns:: 0 if everything is ok, 1 on error

int playing_state	(	rtsp_thread *	rtsp_th,
		short	event
	)

Handles RTSP events when the controller is in PLAYING state

Parameters:

	rtsp_th	The controller for which to handle the events
	event	The event generated by handle_rtsp_pkt

Returns:: 0 if everything is ok, 1 on error

int ready_state	(	rtsp_thread *	rtsp_th,
		short	event
	)

Handles RTSP events when the controller is in READY state

Parameters:

	rtsp_th	The controller for which to handle the events
	event	The event generated by handle_rtsp_pkt

Returns:: 0 if everything is ok, 1 on error

Here is the call graph for this function:

int recording_state	(	rtsp_thread *	rtsp_th,
		short	event
	)

Handles RTSP events when the controller is in RECORDING state. Every event in this state will do nothing, because recording is not implemented

Parameters:

	rtsp_th	The controller for which to handle the events
	event	The event generated by handle_rtsp_pkt

Returns:: Always 0, because recording is not implemented

void* rtsp ( void * rtsp_thrd )

RTSP packets handling main loop Each rtsp controller forks a thread running this loop to handle incoming answers If there are packets pending on the incoming transports it will call handle_rtsp_pkt

Parameters:

rtsp_thrd

The rtsp thread/controller for which to run the loop
